Measuring and monitoring relays
General information
interface
interface
The following statements apply to all devices, unless
contradirected by the information contained in the device’s
specific technical data sheet.
Standards
The devices meet the current standards and regulations:
“Measuring relays and protective facilities”
EN 60255-6:1994
“Thermal protection for rotating electrical machines”
EN 60947-8:2003
“Low-voltage switching devices”
EN 60947-5-1:2004
“Insulation monitoring devices for monitoring of AC networks
through a superimposed DC voltage”
VDE 0413-2:1973
DIN EN 61557-2:1998
“Equipping of power systems with electronic devices”
EN 50178:1997
Rated voltage UN
The voltage type is represented by the indication AC, DC or
AC/DC of the relevant rated voltage.
V AC
These devices are designed for operation under AC voltage.
The corresponding rated frequency is indicated.
V DC
These devices are designed for operation under DC voltage.
We have indicated either the permissible amplitude and the
maximum value of the voltage characteristic of the
superimposed AC voltage according to DIN 41755-1 or the rated
frequency. Devices for which a rated frequency has been
indicated, can also be operated at an unfiltered voltage from a
bridge rectification (no half-wave rectification). In this case the
operating voltage is the root-mean-square value of the voltage.
Ud = arithmetic mean value
uuess = amplitude (peak-to-peak displacement)
û = absolute maximum value of the voltage characteristic = umax
612
AC/DC
These devices are designed for operation under AC and DC voltage.
They can be operated with an unfiltered voltage from a bridge
rectification (no half-wave rectification). The operating voltage is the
root-mean-square value of the voltage.
Operating voltage range
If the rated voltage is indicated as a range, for example 110 to 127 V
and a permissible operating range between 0.8 and 1.1 x UN, the
operating range will extend from 0.8 x 110 V to 1.1 x 127 V.
Rated frequency
The devices can be operated within the indicated range, for
example 50 to 60 Hz, without any restrictions. When 50 to 60 Hz
is indicated, the devices have a frequency selector. When 50 or
60 Hz is indicated, the devices are designed for the relevant
frequency.
Operating range
0.95 to 1.05 x rated frequency. When a rated frequency range is
indicated, for example 50 to 60 Hz, the permissible operating
range is 0.95 x 50 Hz to 1.05 x 60 Hz.
Rated consumption
Devices that are designed for operation with AC voltage are
specified in VA and W corresponding to the rated frequency. If
several rated frequencies are indicated, or a range, the indication
will always refer to 50 Hz. For devices designed for operation
with DC voltage, the values are indicated for a DC voltage
without superimposition. For devices designed for operation
under AC and DC voltage, the same values are indicated as for
AC devices. When the consumption changes during the
functional sequence, the highest value is always indicated. If the
device‘s consumption can be higher for a short period of time, for
example at power ON (DC system, economy connection), its
value will be indicated additionally. Due to capacitors in the
power supply, an increased switch-on peak occurs in electronic
devices.
Release value
When the devices are operated through inductive proximity
switches in 2-wire designs or through long lines in case of AC
voltage, a residual voltage is still applied to the devices, although
the excitation voltage has been switched off. For proper
functioning of the devices this voltage must be lower than the
release value. LEDs for function indications may burn weakly in
case of a residual voltage.

Measuring and monitoring relays
General information
interface
Half-wave rectification
Various devices are equipped with an internal half-wave
rectification. As the devices must be adjusted for operation with
2-wire inductive proximity switches, their half-wave rectification
value is indicated in the key data.
Recovery time
For proper functioning of the device, the value must not fall
below the specified value. See the function diagram for additional
information. This value does not imply that an interruption is
permissible.
Inductive proximity switches in 2-wire design
Inductive proximity switches are subject to specified values for
the residual current that is allowed to flow over the load when
the switch is disabled. These maximum values contradict the
requirement for power consumption of the triggered contactors
and relays to be as low as possible. The market offers inductive
proximity switches with far lower residual currents. In order to
adjust them to the required data of the switches, a field device
can be added parallel to the load (mandatory for field devices
with integrated half-wave rectification). Not all relays can be
operated parallel to the control input, pulse input or zero input
with an additional load. A corresponding indication is made for
each device under “Technical data”.
Mean value of the fault
Deviation of the arithmetic mean value of all the measured values
from the pre-selected value.

The indications relate to end value of the range.
Fixed values
The indications relate to the rated value.
Dispersion
Dispersion means the difference between the smallest
measured value and the largest measured value at a certain
setting and constant setting variable values. The indications for
the devices relate to the pre-selected time value.
Influence of the supply voltage
If an additional error is caused by changing the supply voltage,
this influence is indicated in % for each % of change to the
supply voltage. The rated value is the reference point. This
indication refers to the entire operating range.
Influence of the ambient temperature
If an additional error is caused by changing the ambient
temperature, this influence is indicated in % for each K of
temperature change. The reference point is + 20 °C. This
indication refers to the entire operating range.
Fault influence
If an influence occurs that exceeds the standard value, it must be
indicated accordingly.
Digital
Never set all the selector switches to zero. The position of the
selector switches should not be changed during the functional
sequence, as otherwise this may cause functional faults.

Contacts
Output circuit according to EN 60947-5-1:2004.
Contact material
The contact material is indicated in “Technical data”. So far,
there is no known contact material that would be perfect for the
variety of application options. The major characteristics of the
most important contact materials are listed in the following.
Hard silver
Ag Cu has good conductivity, a high resistance to corrosion and a
low welding tendency. It is suitable for medium to high switching
capacities. An especially sulfurous atmosphere facilitates the
oxidation that may cause contact interruptions. Ag Cu is not
suitable for switching voltages < 6 V.
Silver-cadmium oxide
(Variations indicated with letter W) Ag Cd O contacts have a
lower welding tendency, a higher resistance to corrosion and a
better arc extinction than Ag Cu contacts. Therefore they are
especially well suited for switching inductive and capacitive
loads. Its oxidation resistance is higher than that of Ag Cu.
Ag Cd O is not suitable for switching voltages < 12 V.
Silver nickel
Ag Ni, an important material for inductive loads (6 – 380 V).
Suitable for switch-on current between 10 mA and 100 A. The
contacts have good resistance to corrosion, a low welding
tendency and higher contact resistances than Ag contacts.
614
Silver alloy, gold-plated
Silver alloys with a high resistance to corrosion (Ag Ni, Ag Sn O2)
are used underneath the gold plating, so that the same life span
as with Ag Ni, Ag Cd O or Ag Sn O2 can be expected after the
gold plating is permeated through higher or inductive loads. Low
voltages and currents are safely switched with gold plating.
Please ensure that the gold layer, if required, is not destroyed by
improper use prior to the contact’s intended use.

Application category
In EN 60497-5-1:2004, application categories are indicated for
auxiliary circuit switches. They clearly define the intended
purpose of the switching devices in combination with the rated
operating voltage Ue, the rated operating current Ie, the number
of operating cycles and the test cycle.
EC directives and declaration of conformity
This general technical information applies for all the devices that
may be covered by one or more of the following EC directives:
EC Machine Directive 98/37/EG
EC EMC Directive 89/336/EWG
EC Low-Voltage Directive 73/23/EWG
Voltage type
Application category
AC voltage

The conformity of the devices that meet the requirements of the
corresponding EC directive is indicated by the CE mark of
conformity on the type plate. Information about which directives
and standards are met by the devices is provided by the EC
Declaration of Conformity. If the devices identified as such do not
meet all the directives during the directive’s transition period, this
will be mentioned in the documents that accompany the device.
The devices without the EC mark of conformity meet the
respective standards indicated. This indication functions as
declaration of conformity in the sense of article 10 of the EC
Low-Voltage Directive 73/23. The devices that were put on the
market after 1995-12-31 must meet the requirements of the
EMC Directive. In case of replacement devices that cannot be
operated on their own and do not carry the CE mark, the user
himself is responsible for the proper installation according to
§ 5 sec. 5 EMVG and for the fulfillment of the protection
requirements according to § 4 sec. 1 EMVG. Wieland Electric
GmbH will provide users with the EC declarations of conformity
on request.

Terminal markings and position of the terminals
All devices designed for operation under DC voltage are
protected against destruction in case of incorrect wiring. If this
protection is designed as bridge rectification, the device will work
properly even in the case of incorrect poling. In this case, the
circuit diagram of the corresponding device‘s will not show any
polarity. If the poling protection is designed as half-wave
rectification, the device will not work in the case of incorrect
poling. For an optimal interference suppression of device‘s
designed for AC voltage, terminal A1 should be assigned to L1
and terminal A2 to N. When a control-power transformer is used,
terminal A2 should always be assigned to the line common for all
load bearing devices. In the circuit diagrams in the catalog, the
position of the terminals corresponds to the assignment on the
device.
Subject to change without further notice
Safety instructions
Installation, start-up, modification and retrofit of all devices must
be performed by a qualified electrician only! Disconnect the
device/system from the load prior to starting any work! Follow
the safety instructions of electrical engineering and the trade
association! Negligence of the safety instructions may cause
death, grievous bodily harm or severe material damage!

We reserve the right to make technical changes that result in

Measuring and monitoring relays
Voltage measuring relay NMU 1001
interface
interface
Voltage measuring relay
• For monitoring the upper and lower limit values of single phase voltages
• 3 measuring ranges from AC / DC 0.5 to 500 V
• Sinusoidal, square, delta waveforms
• 16 ON-delay times selectable: no delay, 0.1 s to 3 h
• Frequency range of the measuring variable between 45 and 400 Hz
• Multi-functional: Open-circuit or closed-circuit principle; hysteresis 3 % or
10 % from the setpoint
Applications
• Monitoring of voltage levels
• Monitoring of interference voltage in networks with external power supply
• Monitoring of field excitation of motors
• Monitoring of frequency drives
• Monitoring of analog correcting variables
Functions
The NMU 1001 is a monitoring relay with three measuring ranges for single-phase
voltages between AC / DC 0.5 V and AC / DC 500 V. The frequency range covers 45 Hz
to 400 Hz at AC. The measured value is recorded with an integrated full wave rectifier.
Therefore it is possible to monitor non-sinusoidal currents or voltages (e.g. voltages
with harmonic component). With AC, the devices evaluate the rectifier value calibrated
on the root-mean-square of a sine voltage. With DC measuring values, a rectification is
performed and the mean value is monitored. The effective value itself is not
monitored. As output contact, 1 change-over contact is available. There is an electrical
isolation between the auxiliary supply, the measuring circuit and the output circuit
(relay contact).
Notes
• Operation of the function switch or the time switch during the timing period will
immediately terminate the timing operation.
• With the delay “–” (no delay) and with simultaneous active function (of the response
value), the NMU 1001 will respond to the instantaneous value of the monitoring
variable at a certain threshold and cause the output relay to switch into “quick time”
(see “Response time” under “Technical data”).
• Disconnect the connection cables of the voltage measuring relay prior to performing
an insulation or voltage test.
Circuit diagram
The three measuring ranges are adjusted through the different connections of the
input terminals B1, B2, B3 and B4. The response value is adjusted with the
potentiometer Vx. The device functions and the ON-delay time are adjusted by using
the rotary switches (see “Settings”).
Function of the open-circuit principle
After applying the supply voltage and transgression of the lower limit (<) or upper limit
(>) values of the pre-selected response value, the output relay switches into the ON
position. This occurs according to the pre-selected ON-delay time. When the
monitoring variable returns to the response value, the output relay switches into the
OFF position depending on the adjustment of the hysteresis ( 3 % or 10 %).
Function of the closed-circuit principle
After applying the supply voltage and after the standby time tB, the output relay
switches into the ON position. The transgression of the lower limit (<) or upper limit
(>) of the pre-selected response value, according to the selected function, causes the
output relay to switch back into the OFF position depending on the pre-selected
ON-delay time. When the monitoring variable returns to the response value, the
output relay switches into the ON position depending on the adjustment of the
hysteresis (3 % or 10 %).

Settings:
• Measuring range AC/DC 5 to 50 V (terminals B1 and B3)
• Poti Vx set to 0.5 (0.5 x measuring range end value 50 V) = 25 V (response value)
• Rotary switch ON-DELAY set to 100 s
• Function rotary switch set to > 3
If the monitoring value exceeds the response value of 25 V, the LED TRIPPED will begin
to flash. After the pre-selected ON-delay time of 100 s, the output relay switches into
the ON position and the LED TRIPPED burns continuously. If the actual monitoring
value falls below the response value minus the hysteresis of 3 %, the output relay will
switch back into its OFF position. If it falls below the response value before the preselected ON-delay time is reached, the LED TRIPPED will extinguish (see the Function
diagram).

• Rotary switch ON-DELAY set to “–”
• Function rotary switch set to > 10
If the measured value falls below the response value of 4 V, the output relay will switch
into the OFF position without an ON-delay time, and the LED TRIPPED will light.
If the actual monitoring value exceeds the response value plus the hysteresis of 10 %,
the output relay will switch into the ON position. The LED TRIPPED will extinguish (see
Function diagram).

Voltage measuring relay
• For monitoring the upper and lower limit values of single phase voltages
• 3 measuring ranges from AC / DC 0.5 to 500 V
• Sinusoidal, square, delta waveforms
• 10 time ranges: no delay, 0.1 s to 3 h for the ON-delay time
• Frequency range of the measured value between 45 and 400 Hz
• Multi-functional: open-circuit or closed-circuit principle; hysteresis 3 % or
10 % from the setpoint
Lw
Applications
• Monitoring of voltage levels
• Monitoring of interference voltage in networks with external power supply
• Monitoring of field excitation of motors
• Monitoring of frequency drives
• Monitoring of correcting variables
Functions
The voltage measuring relay SUM 1001 is a monitoring relay for single-phase voltages.
The measured value is fed in through different terminals (see table I) according to the
desired measuring range. With the setpoint potentiometer, the response value can be
adjusted analogically within the pre-selected measuring range. The on-time delay can be
adjusted with the time range switch and the time setpoint potentiometer (see table II).
Function of the open-circuit principle
After applying the supply voltage and transgression of the lower or upper limit values
(depending on the selected function – see table III) of the pre-selected response value,
the output relay switches into the ON position. This occurs either according to the
pre-selected ON-delay time or immediately. The transgression of the limit values
(underflow or overrange) of the response value, according to the selected function, by
at least 3 % or 10 % (hysteresis) causes the output relay to switch back into the OFF
position.
Notes
• The power supply is electrically isolated from the measuring circuit and is
displayed by LED SUPPLY.
• The measured value is recorded with an integrated full wave rectifier. Therefore
it is possible to monitor non-sinusoidal voltages (e.g. voltages with harmonic,
square or delta voltages ranging between 45 and 400 Hz).
• With AC, the devices evaluate the rectifier value calibrated on the root-meansquare of a sine voltage.
• With DC measuring values, a rectification is performed and the mean value is
monitored.
• With NO DELAY and simultaneous active function overrange (> V), the
monitoring relays will respond to the instantaneous value of the monitoring
variable at a certain threshold and cause the output relay to switch into “quick
time” (see Technical Data).
• Disconnect the connection cables of the voltage measuring relay prior to
performing an insulation or voltage test.
Circuit diagram
Function of the closed-circuit principle
After applying the supply voltage, the relay switches into the ON position after tB. The
transgression of the lower or upper pre-selected limit values, according to the selected
function, causes the output relay to switch back into the OFF position depending on
the pre-selected ON-delay time. Depending on the pre-selected hysteresis (3 % or
10 %), the output relay switches back into the ON position after the corresponding
transgression of the lower or upper response value.

After the pre-selected ON-delay time of 210 s, the output relay switches into the ON
position and the LED TRIPPED burns continuously. If the actual measured value falls
below the setpoint minus the hysteresis of 3 %, the output relay will switch back into its
OFF position. If it falls below the measured value before the pre-selected ON-delay time
is reached, the LED TRIPPED will extinguish (see Function diagram 1).

Current measuring relay
• For monitoring the upper and lower limit values of single phase voltages
• 2 designs, each with measuring ranges between AC/DC 2 and 500 mA
or 0.1 and 15 A
• Sinusoidal, square, delta waveforms
• 16 ON-delay times selectable: no delay, 0.1 s to 3 h
• Frequency range of the measuring variable between 45 and 400 Hz
• Multi-functional: Open-circuit or closed-circuit principle; hysteresis 3 %
or 10 % from the setpoint
Applications
• Monitoring of current levels
• Monitoring of power requirements
• Monitoring of frequency drives
• Monitoring of correcting variables
• Monitoring of heating elements
Functions
The NMI 1001 is a monitoring relay for single-phase currents. There are two types
with different measuring ranges. The frequency range covers 45 Hz to 400 Hz at AC.
The measured value is recorded with an integrated full wave rectifier. Therefore it is
possible to monitor non-sinusoidal currents (e.g. currents with harmonic component).
With AC, the devices evaluate the rectifier value calibrated on the root-mean-square of
a sine voltage.
With DC measuring values, a rectification is performed and the mean value is
monitored. The effective value itself is not monitored. As output contact, 1 changeover contact is available. There is an electrical isolation between the auxiliary supply,
the measuring circuit and the output circuit (relay contact).
Notes
• Operation of the function switch or the time switch during the timing period will
immediately terminate the timing operation.
• With the delay “–” (no delay) and simultaneous active function overflow (of the
response value), the NMI 1001 will respond to the instantaneous value of the
monitoring variable at a certain threshold and cause the output relay to switch into
“quick time” (see the ‘Response time’ under Technical Data).
• Disconnect the connection cables of the current measuring relay prior to performing
an insulation or voltage test.
Circuit diagram
The three measuring ranges are adjusted through the different connections of the
input terminals B1, B2, B3 and B4. The response value is adjusted with the
potentiometer Ix. The device functions and the ON-delay time are adjusted by using
the rotary switches (see “Settings”).
Function of the open-circuit principle
After applying the supply voltage and transgression of the lower limit (<) or upper limit
(>) values of the pre-selected response value, the output relay switches into the ON
position. This occurs according to the pre-selected ON-delay time. When the
monitoring variable returns to the response value, the output relay switches into the
OFF position depending on the adjustment of the hysteresis ( 3 % or 10 %).
Function of the closed-circuit principle
After applying the supply voltage and after the standby time tB, the output relay
switches into the ON position. The transgression of the lower limit (<) or upper limit
(>) of the pre-selected response value, according to the selected function, causes the
output relay to switch back into the OFF position depending on the pre-selected ONdelay time. When the monitoring variable returns to the response value, the output
relay switches into the ON position depending on adjustment of the hysteresis (3 %
or 10 %).

• Rotary switch ON-DELAY set to “–”
• Function rotary switch set to > 10
If the monitoring value exceeds the setpoint of 50 mA, the LED TRIPPED will begin to
flash. After the pre-selected ON-delay time of 100s, the output relay switches into the
ON position and the LED TRIPPED burns continuously. If the actual monitoring value
falls below the response value minus the hysteresis of 3 %, the output relay will switch
back into the OFF position. If it falls below the response value before the pre-selected
ON-delay time is reached, the LED TRIPPED will extinguish (see the Function diagram).
If the monitoring value falls below the setpoint of 12 A, the output relay will switch into
the OFF position without an ON-delay time, and the LED TRIPPED will light.
If the actual monitoring value exceeds the response value plus the hysteresis of 10 %,
the output relay will switch into the ON position.

• For monitoring the upper and lower limit values of single phase voltages
• 2 designs, each with measuring ranges between AC/DC 2 and 500 mA
or 0.1 and 15 A
• Sinusoidal, square, delta waveforms
• 10 time ranges: no delay, 0.1 s to 3 h for the ON-delay time
• Frequency range of the measuring variable between 45 and 400 Hz
• Multi-functional: Open-circuit or closed-circuit principle; hysteresis 3 % or
10 % from the setpoint
Lw
Applications
• Monitoring of current levels

• Monitoring of frequency drives
• Monitoring of analog correcting variables
• Monitoring of heating elements
Circuit diagram
Functions
The current measuring relay SUM 1001 is a monitoring relay for single-phase voltages.
The measured value is fed in through different terminals (see table I) according to the
desired measuring range. With the setpoint potentiometer, the response value can be
adjusted analogically within the pre-selected measuring range. The on-time delay can be
adjusted with the time range switch and the time setpoint potentiometer (see table II).
Function of the open-circuit principle
After applying the supply voltage and transgression of the lower or upper limit values
(depending on the selected function – see table III) of the pre-selected response value,
the output relay switches into the ON position. This occurs either according to the
pre-selected ON-delay time or immediately. The transgression of the limit values
(underflow or overrange) of the response value, according to the selected function, by
at least 3 % or 10 % (hysteresis) causes the output relay to switch back into the OFF
position.
Function of the closed-circuit principle
After applying the supply voltage, the relay switches into the ON position after tB. The
transgression of the lower or upper pre-selected limit values, according to the selected
function, causes the output relay to switch back into the OFF position depending on
the pre-selected ON-delay time. Depending on the pre-selected hysteresis (3 % or
10 %), the output relay switches back into the ON position after the corresponding
transgression of the lower or upper response value.
628
Notes
• The power supply is electrically isolated from the measuring circuit and is displayed
by LED SUPPLY.
• The measured value is recorded with an integrated full wave rectifier. Therefore it is
possible, in certain ranges, to monitor non-sinusoidal currents (e.g. currents with
harmonic, square or delta voltages ranging between 45 and 400 Hz).
• With AC, the devices evaluate the rectifier value calibrated on the root-mean-square
of a sine voltage.
• With DC measuring values, a rectification is performed and the mean value is
monitored.
• With NO DELAY and simultaneous active function overrange (> V), the monitoring
relays will respond to the instantaneous value of the monitoring variable at a certain
threshold and cause the output relay to switch into “quick time” (see Technical
Data).
• Disconnect the connection cables of the voltage measuring relay prior to performing
an insulation or voltage test.

Table II:
• Time range end value NO DELAY
• Potentiometer setpoint set to any value = without ON-delay time
Table III:
• Function > A 3 %
• Function selector in position 4
If the measuring value exceeds the setpoint of 50 mA, the LED TRIPPED will begin to
flash. After the pre-selected ON-delay time of 210 s, the output relay switches into
the ON position and the LED TRIPPED burns continuously. If the actual measuring
value falls below the setpoint minus the hysteresis of 3 %, the output relay will
switch back into the OFF position. If it falls below the measured value before the preselected ON-delay time is reached, the LED TRIPPED will extinguish (see Function
diagram 1).
Table III:
• Function < A 10 %
• Function selector in position 8
If the measured value falls below the setpoint of 12 A, the output relay will switch into
the OFF position without an ON-delay time, and the LED TRIPPED will light. If the actual
measured value exceeds the setpoint plus the hysteresis of 10 %, the output relay will
switch into the ON position. The LED TRIPPED will extinguish (see Function diagram 4).

Applications
• Monitoring of field excitation of motors
• Monitoring of interference voltage in networks with external power supply
• Monitoring of overvoltage levels
• Monitoring of overcurrent levels
Function
The measuring relay is connected to a permanent supply voltage of 50 to 60 Hz. The
current or voltage to be monitored is supplied via terminals B1/B2. The supply voltage
circuit and the measuring circuit are electrically isolated by means of a transformer.
A response value and a release value are set on the relay. If the measured value
exceeds the response value, the relay will switch. If the measured value falls below
the release value, the relay will fall back into its initial position. The release value
is adjustable within the range between 0.5 and 0.95 of the response value.
SXT 12 – open-circuit principle
When supply voltage is applied, the SXT 12 is in OFF position.
If the response value is exceeded, it will switch into the ON position.
If it falls below the release value, the relay will switch back into the OFF position.

SXT 32 – closed-circuit principle
When supply voltage is applied, the SXT 32 switches into the ON position. If the

Notes
• Unfiltered or partially filtered DC voltages and currents can also be monitored in the
measuring circuit. It should be observed that the relay responds to the positive peak
values, but is adjusted to the corresponding root-mean-square values at 50 Hz.
• Negative currents are not measured but also not influenced
(same operating range as for the positive currents).

Application examples RPM monitoring
The rpm delivered by the tachogenerator is transformed into a voltage measurement.
This voltage (measured value) is monitored by the SXT 32 measuring relay. If the

position (closed-circuit principle). The fault will be indicated by lamp H1.
The flow can be controlled by the PLC.
Current monitoring for the load
If the current in the load (measured value) exceeds the pre-selected response value,
the relay switches into the OFF position (closed-circuit principle). The fault will be

The response time is the time interval
between the occurrence of a measured
value and the change-over of the relay. It is
influenced by the factor by which the
measured value exceeds the response
value. The permissible interference pulse
width is the duration of an interference
pulse at which the relay does not yet
respond.

Measuring and monitoring relays
Voltage monitor SUW 1001
interface
DC or AC monitor without auxiliary supply
• For single-phase networks
• Large adjustment range and large operating range
• Adjustable upper and lower limit
• Closed-circuit principle
Applications
• Monitoring of emergency power systems
• Protection of EDP installations
• Building protection engineering
• Protection of PLC robot systems
• RPM monitoring with generator
• Monitoring of generator voltages
Circuit diagram
Function
A lower and an upper limit value are set via potentiometers on the voltage monitor.
After applying the supply voltage to terminals A1/A2, the voltage monitor switches
into its operating position (closed-circuit principle). This requires, however, that the
applied voltage lies between the two pre-selected limit values. After transgression of
the upper or lower limit value, the device switches into its OFF position.
• An additional auxiliary supply voltage is not required (two-wire technology)
• The limit values are set via potentiometers on the front of the unit
• The switching hysteresis is set to an permanent value
Note
• No electrical isolation between the measuring and input circuits

Protection of robotic systems
The SUW 1001 prevents malfunctioning of the PLC robot system when the voltage
fluctuations are too large.
If the limit value is exceeded, damage is limited to the PLC
(running in a safe mode), and an emergency shut-down is initiated for the robots.
Emergency power monitoring
The SUW 1001 monitors the main voltage.
If the main voltage fails or if it differs from its design value, the system will switch over
to a backup voltage (battery) (contacts 15-16, 25-26).

Applications
• Monitoring the supply voltage of installations such as:
• Crane and elevator systems
• Machines with reversal of rotational direction
• Pumps, condensers or compressor systems
• Air conditioning and ventilation systems
• Distribution stations
• Escalators
Function
The SAM 1001 monitors the external line voltages L1, L2, L3.
It monitors:
• whether three-phase voltages are applied
• the phase sequence
• the balance
If the parameters are faultless, the SAM 1001 will switch into its ON position. If one of
the conditions is not fulfilled, the relay will remain in its OFF position. The red LED
lights up. It is reset automatically after the fault has been eliminated.
If a phase failure occurs during operation, this will be recognized even when a voltage
feedback occurs through a connected field device. The relay falls back into its OFF
position and the red LED lights up. An imbalance limit value can be set on the relay.
A response time and release time of 1000 ms each is permanently set internally.
It prevents the relay from responding during short-term imbalance voltage increases
or line breakdown. The relay will not switch in case of balance voltage drops in the
network.

• Monitoring of three-phase current network fault on machines or systems, such as:
• Processing machines, palletizing systems, packaging machines
• Machines with reversal of rotational direction
• Escalators and elevator systems
• Pumps and compressors
• Air conditioning and ventilation systems
Circuit diagram
Function
The SPW devices monitor their external line voltages
(their own three-phase power supply) L1, L2, L3 for:
• Phase sequence in clockwise rotation
• Phase failure
• Phase voltage imbalance
• Phase shift
• Undervoltage
After applying the external line voltages L1, L2, L3 and with correct three-phase
current parameters, the SPW switches into the ON position (closed-circuit principle).
The green LED lights up. If one of the above mentioned conditions is not fulfilled, the
relay will remain in or switch into its OFF position. The SPW operates without auxiliary
supply voltage and neutral connection. The rated voltage for the three-phase current
networks can be pre-selected in 3 ranges – 3 AC 380 V, 400 V, 415 V – analog with a
potentiometer on the front of the device. If a fault occurs, the relay will switch into its
OFF position with a reaction time of 35 ms. The green LED will extinguish. After the
fault has been removed, the SPW automatically switches into its ON position and the
LED lights up.
Fault detection occurs at:
• Incorrect phase sequence
• Phase failure of 100%, such as wire breakage in the lines leading to the device
• Phase failure even at back-voltage up to 85%
• Undervoltage detection up to 20% of one, two or all three phases, related to the
adjusted voltage of 3 AC 380 V, 400 V, 415 V
• Phase voltage imbalance above 15%
• Phase shift of one phase compared to the other phases
The two devices differ in their contact assignments. The SPW 1004 is fitted with two
change-over contacts, while the SPW 1005 is fitted with one change-over contact.

Function
The SAP devices monitor their correct phase sequence after phases L1, L2, L3 have
been applied (clockwise rotation). With a pure ohmic load, a phase failure is also
detected.
After applying the external line voltages L1, L2 L3 and if the phase sequence is
correct, the relay will switch into the ON position. If one of the conditions is not
fulfilled, the relay will remain in the OFF position. The red LED lights up.
If a phase failure occurs during operation, the relay will switch back into the OFF
position (the red LED lights up), if no voltage feedback occurs through the connected
loads. It is reset automatically after the fault has been eliminated.
The two devices differ in their contact assignments.
The SAP 1002 is fitted with one change-over contact, while the SAP 1003 is fitted with
two change-over contacts.

Three-phase voltage monitor without auxiliary supply voltage
• Undervoltage detection of one, two or all three phases
• Adjustable undervoltage detection between 285 and 360 V
• Detection of phase failure of one, two or all three phases
• Rated three phase voltage 3 AC 400 V without neutral connection and
auxiliary supply voltage
• Reaction time 35 ms
• Closed-circuit principle
• Contact assignment: 2 change-over contacts
L
Application examples
• Monitoring of three-phase current – undervoltage faults and phase failure
of machines or systems, such as:
- Machines with reversal of the direction of rotation (cranes, robots, pumps,
excavators, conveyor systems, etc.)
- Chemical processes
- Test and calibration systems
Circuit diagram
Function
The SUW 3001 monitors the external line voltages (its own voltage supply) L1, L2, L3
for undervoltage and phase failure.
It works without a neutral connection and an auxiliary supply voltage.
Setting ranges
The three-phase undervoltage range of 3 AC 285 V to 360 V of all three phases can be
adjusted finely with an integrated potentiometer.
After applying the external line voltages L1, L2, L3, the voltages of which exceed the
voltage limit value, the SUW switches into its ON position (closed-circuit principle).
The green LED lights up. If the voltage falls below the pre-selected voltage limit value,
the relay will switch into its OFF position. The green LED extinguishes.
The rated voltage for three-phase current networks is 3 AC 400 V with a large
operating voltage range. The setpoint value of the undervoltage can be pre-selected to
between 285 and 360 V with a potentiometer. If a fault occurs, the relay will switch
into its OFF position with a reaction time of 35 ms. The green LED will extinguishes.
After elimination of the fault, the SUW switches automatically into its ON position and
the pre-selected 10 V hysteresis applies. The green LED lights up.
Fault detection occurs at:
• Phase failure of one, two or all three phases
• Undervoltage detection of one, two or all three phases, related to the adjusted
voltage of 3 AC 285 V to 360 V

Circuit diagram
Functions
SBW 1004 – open-circuit principle
When the motor is switched on, the adjustable start-up override time on the relay
begins. After this time has elapsed, the SBW 1004 monitors the pre-selected phase
shift cos ϕ (in °). When the load falls, the phase shift becomes larger –
cos ϕ becomes smaller. If the pre-selected phase shift is exceeded, the relay will
switch into its ON position after expiration of the pre-selected response time. If the
phase shift falls below the pre-selected value – back to a normal load – the relay will
switch into OFF position after expiration of the pre-selected release time. The preselected response and release times (1000 ms) prevent the relay from responding
during brief deviations from the setpoint value.
SBW 1005 – closed-circuit principle
When supply voltage is applied, the relay switches into the ON position.
When the motor is switched on, the adjustable start-up override time on the relay
begins. After this time has elapsed, the SBW 1005 monitors the pre-selected phase
shift cos ϕ (in °). When the load falls, the phase shift increases – cos ϕ decreases. If
the pre-selected phase shift is exceeded, the relay will switch into its OFF position
after expiration of the pre-selected response time. If the phase shift falls below the
pre-selected value – back to a normal load – the relay will switch into the ON position
after expiration of the pre-selected release time. The pre-selected response and
release times (1000 ms) prevent the relay from responding during brief deviations
from the setpoint value.
SBW 1004/SBW 1005 – with fault memory
The fault memory is put into operation by shunting the terminals Y1, Y2. If the phase
shift falls below the pre-selected value – back to normal load – the relay will remain in
the ON/OFF position. The fault memory is cleared only by being reset; the relay
switches into the OFF/ON position. If the pre-selected phase shift is still exceeded,
the relay will switch into the OFF/ON position only during the resetting.
Note
• Short-circuit the transformer before

• If the rated motor current is higher than
5 A, a current transformer must be used.
The current transformer must be designed
for a load of RI + 2 x RL.

Application examples Monitoring a conveyor belt
The load monitor SBW 1004 controls the conveyance quantity. If too little material is
supplied – falling load – the relay will switch into its ON position after expiration of the
pre-selected response time.
Monitoring dust filters
The load monitor SBW 1005 monitors the filter for contamination. If the filter is
contaminated, the motor load falls – cos ϕ becomes smaller. If the pre-selected phase
shift is exceeded, the relay will switch into its OFF position after expiration of the preselected response time – closed-circuit principle. The fault is stored until the reset key
is operated manually.
Rated motor current > 5 A
Single-phase network, e.g. 230 V
Rated device voltage 3 AC 230 V
Principle
With an inductive load, the current lags behind the voltage by phase angle ϕ.
If the load on the motor falls, the phase angle becomes larger and subsequently cos ϕ
becomes smaller. This change of phase angle is a precise measure of the load change
at the motor shaft. The load monitor monitors the phase shift between the voltage
and the current under inductive loads in a sinusoidal single-phase and three-phase
network. (Not suitable for phase control and frequency-controlled motors).

• Short-circuit the transformer before
disconnecting the relay.
• If the rated motor current is higher than
5 A, a current transformer must be used.
The current transformer must be
designed for a load of RI + 2 x RL.

Monitoring of rolls
The load monitor SBW 1007 monitors the roll contact pressure. If the roll contact
pressure rises, the motor load also rises (cos ϕ becomes larger). If the phase shift falls
below the pre-selected value, the relay will switch into its OFF position (closed-circuit
principle).
Rated motor current 0.1 to 5 A
Three-phase network, e.g. 230 V
Rated device voltage 3 AC 230 V
Principle
With an inductive load, the current lags behind the voltage by phase angle ψ.
If the load on the motor falls, the phase angle becomes larger and subsequently
cos ϕ becomes smaller. This change of phase angle is a precise measure of the load
change at the motor shaft. The load monitor monitors the phase shift between the
voltage and the current under inductive loads in a sinusoidal single-phase and threephase network. (Not suitable for phase control and frequency-controlled motors).
Monitoring a crusher
The load monitor monitors the stone crusher for overload. If the phase shift falls below
the pre-selected value as the motor load rises (e.g. through jamming), the load monitor
will switch. The fault is stored until the reset key is operated.

Circuit diagram
Functions
SMS 1002
After applying the supply voltage (A1/A2) and connection of the PTC
thermistor (T1/T2), the relay switches into the ON position. It operates according
to the closed-circuit principle and ensures safe switch-back into the OFF
position in case of the following malfunctions:
• Due to the increasing temperature, the PTC thermistor exceeds a resistance value in
the range ≥ 2500 Ω to ≤ 3600 Ω (when the temperature decreases and the PTC
thermistor’s resistance value ranges between ≤ 1500 Ω and ≥ 1000 Ω, the relay will
switch back into the ON position)
• The sensor circuit falls below a resistance value of < 20 Ω in case of short circuit
• Damage to the cables
• Power failure
The fault is indicated when the LED TRIPPED lights up. The fault is not stored.
SMS 1005
The basic function corresponds to that of the SMS 1002. An additional fault memory
prevents the relay from switching back into the ON position after elimination of the
fault. The fault memory can be cleared by operating the reset key only if the fault has
been eliminated. The SMS 1005 will be ready for another fault identification only if the
fault memory has been cleared or the supply voltage has been switched off for at least
250 ms.

Sensor
PTC thermistors (temperature sensors) are resistances with very high positive
resistance temperature coefficients. (PTC = positive temperature coefficient). They
are installed in the outlet air side of the stator end winding of those motors for which
the temperature diagram is known prior to manufacturing. Their rated operating
temperature (TNF) depends on the motor type. When the rated operating temperature
is exceeded, the resistance value of the PTC thermistors will increase abruptly. If this
sensor is connected to a motor protection relay/temperature monitor, the abrupt
increase in the resistance value will cause the relay to switch.

be switched back into the ON position (reset).
Monitoring transformer temperature
When the rated voltage temperature (TNF) is exceeded, the relay switches into the

Circuit diagram
Function
The digitally pre-selected limit value is compared with the measured value of the NiCrNi temperature sensor. If the measured value exceeds the limit value, and if there is
no damage in the sensor cable, the temperature monitor will switch. The >∂ LED
lights up. If the measured temperature value falls below the pre-selected hysteresis,
the STW will switch back into its initial position. Supply voltage, overtemperature, and
damage or short circuit of the sensor cable are displayed through the SUPPLY LED or
BREAK LED. The rated voltage is electrically isolated from the measuring circuit. STW

The temperature difference between the measuring point and the reference junction
generates a thermal voltage between the two elements. This is evaluated by the
STW. The equalizing conductors are used as an extension of the thermocouples
(principle diagram). They are installed from the connection of the thermocouple to the
reference junction (equalizing box, measuring point selector).
The equalizing conductors consist of a positive and a negative conductor. They have
the same thermoelectrical properties as the thermocouple up to +200 °C. For this
reason, no thermal voltages occur at the connection points. The highest temperature
for the equalizing conductors is + 200 °C, regardless of the insulation material used. If
the temperature at the connection point is higher, a thermal conductor must be used
instead of an equalizing conductor in order to achieve greater measurement accuracy.
Equalizing conductors are less expensive than thermal conductors. Normally they
have a larger cross section and a lower electrical resistance. From the economic point
of view they are better suited for long lines.

Temperature monitoring for baking installations
The temperature in the baking installation is monitored with the NiCr-Ni thermocouple.
If the set temperature limit value is exceeded (because the temperature regulation
failed due to the PLC), the STW will switch off the oven. At the same time a fault
signal is sent out through the second change-over contact.
Application examples
Temperature monitoring in galvanic processes
The temperature in the galvanic process is monitored with the NiCr-Ni thermocouple.
If the temperature rises to a dangerous value (over the set limit value), the heating is
switched off through the break contact 25/28. At the same time the fault indicator
lamp is switched on (contact 15/16).

• Supply voltage and control circuit electrically isolated
• ON-delay and OFF-delay times adjustable between 0.05 and 1 s
• Contact assignment:
SST 12: 2 change-over contacts

SST 12
Applications
• Protection of sensitive switching contacts such as measuring instruments,
manometers pressure monitors
• Avoidance of contact bouncing
• As timer relay for short times (ON-delay and OFF-delay times)
• As level monitor in connection with float switches
KST 12
Circuit diagram
Function
SST 12
The contact protection relay is constantly connected to a supply voltage. The supply
voltage circuit and the control circuit are electrically isolated by means of a
transformer.
If the control circuit is closed (for example by exceeding the limit value in a contact
manometer), the relay will switch into the ON position when the pre-selected
ON-delay time has elapsed.
When the control contact is opened, it will switch back into the OFF position after
elapse of the OFF-delay time. The ON-delay time and the OFF-delay time are identical.
The open control contact is supplied with a voltage ≤ 11 V DC. A current ≤ 2 mA DC
flows over the closed control contact. This way, the control contact is not overloaded.
Contact assignment: 2 change-over contacts
KST 12
It functions just like the SST 12, however the number of contacts are 1 NO, 1 NC.
Notes
• On contact manometers, a control contact indicates the exceeding of the preselected limit value. The contact should not impede the movement of the pointer.
In order to fulfill this condition, very small control contacts are used. They support a
maximum load of 25 mW.
With higher loads the contacts would be destroyed.
• A correct function is guaranteed if the total ohmic value of lines and contact
resistances does not exceed 500 Ω.
