DIN-RAIL REMOTE PULSE RECEIVER
The CLIP-485 pulse receiver makes it possible to remote-monitor the energy consumption data provided by several meters from
a PC, in which the ENERGY-VIEW software is installed.
◗ Each remote pulse receiver can concentrate up to a max of 8 output signals proceeding from the energy meters in the ENERGY
series and located at a maximum distance of 25 m
◗ Connection to the PC by the RS-485 serial line under the “MODBUS” protocol
◗ To each RS-485 serial line it is possible to connect (an AWG 32 cable is recommended):
— up to 31 remote pulse receivers without using signal amplifiers, provided that they are located no farther than 1000 m
— up to 247 remote pulse receivers in groups of 30, separated by proper signal amplifiers

CONTROL RELAYS - PSR/MCR/LCR
OVERVIEW
PSR
No-phase, voltage-asymmetry, phase-sequence relays
Relay to detect the exact phase sequence in three-phase systems and the
voltage imbalance caused by the reduction or loss of a phase. This device
is useful in applications in which it is essential to respect the phase
sequencing at startup or prevent high power-voltage fluctuation.
• The output relay is energized with a delay of 2s, only if all three phases
are powered and their sequence meets the coding of the input
terminals.
• When under operation, the output relay de-energises if phase sequence
is altered, there is a phase loss or if voltage imbalance exceeds the set
asymmetry threshold.
• Relay sensitivity can be adjusted between 70 % and 95 % of the rated
value by an Asymmetry trimmer (%) located on the front of the device. At
installation sensitivity can be adapted to the voltage imbalance that can
be tolerated by the equipment or system that the relay is meant to protect
(see box "Operation diagrams 2").
• To avoid undesired relay tripping in case of mild voltage imbalance, it is
recommended to adjust starting from the maximum asymmetry value
(70% of Un).
• Re-engagement is automatic as soon as normal power conditions are
restored or the phase sequence error disappears
• Following phase-asymmetry relay tripping, re-engagement is marked by
a hysteresis value that enables the output relay to be energised only
when the voltage value reaches above a predetermined ASYMMETRY
THRESHOLD (see box Operation diagrams 2”).
• Extreme ease of installation is ensured by a compact enclosure (a cover
protects control and adjustment elements) and by a very functional layout
of connection terminals, with loss-proof screws and IP20 protection
rating.
MCR Motor-alternation control relay
Alternation relay designed to provide a level wear and tear of pumps, compressors, generators, etc. when two units – a working unit and a standby unit –
are installed.
The operating principle is based on alternating start commands at every closure of the contacts controlled by an external automatic device (like a pressure
switch).
It is also possible to command alternate/simultaneous operation and changeover-control of several motors.
• Extreme ease of installation is ensured by a compact enclosure (a cover guard protects control and adjustment elements) and by a very functional layout
of connection terminals, with loss-proof screws and IP20 protection rating.
LCR
Electrically conductive liquid-level control relay
High-sensitivity relay to control the level of electrically conductive liquids. When associated to the suitable electrodes, and involved in the control circuit of
pumping systems, this device is used to keep the level in sumps or storage tanks within the established limits and to protect submersible pumps against
idle running.
The relay can also be used as a minimum/maximum liquid-level alarm, or as a no-liquid detector. The operation principle is based on the variation of the
resistance value in the liquid, detected by either 2 or 3 electrodes, depending on the material the sump or tank is made of, whether metal or not.

IMPORTANT
■ For correct relay operation, terminal 9 needs to be
connected to EARTH.
■ It is advisable for the conductors connecting the
electrodes to be separated from the power wires,
especially for long distances.
■ Otherwise, the use of shielded wires is
recommended.

controlled by the MAX electrode is reached

ALTERNATE/SIMULTANEOUS COMMAND OF TWO MOTORS
In this case both main contact P1/G1, and secondary contact P2/G2 are used,
which are controlled by two external automatic devices (like two pressure
switches) with two different tripping thresholds.
Every time contact P1/G1 trips, one of the two motors is started alternately, and
the work function is switched.
If contact P2/G2 trips, the second motor is started as a backup measure when, for
example, one pump is unable to meet the pumping requirements. See the box in
“Operating diagrams 2”.
If the line is powered when both contacts P1/G1 and P2/G2 are closed, the start of
the second motor is delayed by 2 seconds, the breakaway current - and
consequently the coil power-voltage fluctuation - are reduced to a half
Secondary contact P2/G2 keeps a "backup" function even in case of failure of
main contact P1/G1.
This means that one of the two motors will be instantly started and, 2 seconds
later, the backup motor will be started.

CONTROL OF ONE LIQUID LEVEL (DANGER LEVEL)
The output relay energises every time the liquid reaches the level controlled by the
LEVEL electrode.
Thee opposite occurs as soon as the electrode is not submersed in the liquid, as
the relay is not self-powered in this type of control.
