The following signals (if needed) are directly applied to the control unit:







Voltage of mains and generator
Current of generator
Four analogue sensors
Pick-up
Two analogue output signals
Optical fibre or USB for parameterisation
Two CAN bus systems.
Although the control system is protected against reverse polarity, the correct polarity when connecting the battery voltage must be strictly observed, as reverse diodes or other electronic parts of the
switchboard may possibly be damaged.
The fuse on the RZ 071-D will be blown if the control system is connected with the wrong polarity!
Due to the fact that most of the control relays may be configured for various functions, only the
status print out of the supplied control unit is to be considered as a binding document. It must be
observed, that in case of a possible replacement of a unit, any modifications made after commissioning cannot be taken into account by the manufacturer.
5.1.

Select a line by pressing the keys [↓] (down) and [↑] (up). The selection starts again with the other
end of the 'page', when the top or bottom of the 'page' is reached.
To select directly the ACTUAL VALUES group: hold down the LED TEST button, and press [←].
To display the group CURRENT ALARMS hold down LED TEST and press [→].
To modify a parameter: first enter the relevant IDENT-NUMBER.
Note: Parameters of group 0, -GENERAL PARAMETERS-, can be modified without entering this number.
Parameters are modified as follows:
1. Select the required parameter group with the [←] and [→] buttons.
2. Select the required parameter line with the [↓] and [↑] buttons.
3. Press OFF and LED TEST (function: PARA ON or PARA OFF) together. This opens parameterisation
mode as can be seen by the specific cursor [ █ ]. The selection of the group cannot be changed
now.
4. Press [↓] / [↑] to select the desired parameter.
5. Press OFF and ALARM OFF (ENTER function) together to select the parameter line. The shape of

PIN Number, Ident-Number
To modify a parameter, you first have to enter the relevant IDENT-NUMBER. This number is compared
with the PIN NUMBER, and if they are identical, the user is authorised to parameterise the device. The
user can chose any PIN NUMBER between 00000 and 50000. The PIN NUMBER and IDENT-NUMBER are
factory-set to 00000.
A special IDENT-NUMBER can be enquired from the factory if you forget your PIN NUMBER, so that a
new PIN NUMBER can be entered. Modify the PIN NUMBER as follows:
1.Enter the currently valid Ident-Number. The pin number is now also shown.
2.Enter a new PIN Number.
The Ident-number previously entered is now no longer valid.
The IDENT-NUMBER is deleted 15 minutes after the last input, if the user has not previously set it to an
invalid value.
The automatic deletion of the IDENT-NUMBER is, however, not carried out while 00000 is set as
the PIN.

The control unit can control up to 64 alarms. The texts and trigger inputs for alarms 1 to 19 and 49 to
64 are variable, i.e. their texts and actuation are determined by the parameterisation software
PARAWIN. The alarms are actuated by terminals 1 to 14 or free terminals on the relay unit RZ 071-D or
by internal flags (e.g. controller failures, limit value on an analogue channel too high, etc.). The
parameterisation is described above.
Alarms can be divided into three groups:
 Alarms that are monitored only after a delay when the engine is running (e.g. LOW LUB OIL
PRESSURE), called DELAYED. The green MONITORING ON indicator shows that they are monitored.
 Alarms, which are monitored even when the engine is at a standstill, except in operation mode
OFF, (e.g. BATTERY UNDERVOLTAGE), called UNDELAYED.
 Alarm signals 13 and 14 are always monitored, even in operation mode OFF. They are used for
alarms such as LEAKAGE. In operation mode OFF the audible signal is not switched on, but the
alarms are collected together in common alarms. They act just like normal alarms when any other
operation mode than OFF is selected.
The alarms are configured as follows:
 Alarm is active or inactive
 Contact is normally open or normally closed
 Delayed or undelayed monitoring
 Warning or shutdown
 In addition for warning alarms: With or without generator cut off and stop after the re-cooling period
in AUTO mode.
The genset is stopped after the re-cooling period and the automatic control is locked if the
generator is cut off after a warning alarm in the AUTO mode.

At terminal inputs, an alarm is triggered when the corresponding signalling switch closes (normally
open, make contact) or opens (normally closed, break contact). In case of analogue signals an alarm
is triggered, when the actual value is higher than the UPPER LIMIT (alarm pre-set for make contacts) or
the actual value is lower than the LOWER LIMIT (alarm pre-set for break contacts). Alarms 11 to 14 can
additionally be parameterised as break signals of output relays, i.e., the corresponding relay is
activated when the alarm is inactive.
8.2.
Alarm Announcing and Acknowledgement
As long as no new alarm is waiting for acknowledgement, the ACTUAL ALARMS group can be selected
with the [←] and [→] buttons, or by pressing LED TEST and the [→] button at the same time.
The indicator COMMON ALARM (yellow one in the left row of the panel) is flashing when an unacknowledged alarm is present. The acoustic signal is switched on at the same time. Press the ALARM OFF
button to turn off the acoustic signal and bring up the page of the ACTUAL ALARMS on the display.
The alarm text is preceded either by <NEW> if the alarm has not been acknowledged or <ACKN> if it
has been acknowledged.

Display when no alarms
are activated
Press the ALARM OFF button to acknowledge the indicated alarm or to delete a previously acknowledged alarm if the cause of the malfunction has been removed.
When all alarms have been acknowledged, the COMMON ALARM indicator stops flashing and lights
up steadily. It starts to flash again when a new alarm is notified.
The COMMON ALARM switches off when all alarms have been deleted. Move through the activated
alarms with the [↑] and [↓] buttons to acknowledge or delete them with the ALARM OFF button.
If no alarms are pending, the announcement -NO ALARMS PRESENT is displayed.
If the generator is switched off by a warning alarm whilst in AUTO mode, the motor is stopped
after the re-cooling time, and the automatic mode is locked.
8.3.
Explanation of Alarms
8.3.1.
Engine keeps running
This alarm is announced when the engine is still running after the stop procedure. It means that the
stopping equipment of the engine (stopping solenoid, gas valve, etc.) is defective.
8.3.2.
Engine fails to start
This alarm comes up (and the automatic operation is locked) when the engine is not running after the
start sequence.
8.3.3.
Engine fault
This alarm is activated if the engine stops without having a stop command from the control unit. The
control system is locked at the same time.
8.3.4.
Overspeed
The generator frequency or a pick-up signal is used for monitoring overspeed. The alarm GENERATOR
UNDERVOLTAGE must be enabled as a shutdown alarm when the generator frequency is used. This
also protects the engine if the generator voltage fails.
8.3.5.
Alarms 13 and 14
The input signals for these two alarms can be delayed for 0 to 240 seconds. That means that the
alarm contact must be activated for the programmed time before the alarm comes up. Furthermore
these two alarms are also enabled in the operation mode OFF, however without the audible signal.
Fault signals, which have to be always signalled, can be monitored by this (e.g. tank filling level,
leakage).

8.3.6.
Battery voltage Monitor
A relay (with a break function) can be programmed for the direct output of the battery voltage monitor.
It is energised if the voltage is good. A remote signal is possible by this even in the operation mode
OFF.
8.3.7.
Analogue Input Alarms
The analogue inputs can be fitted with modules for various sensors (PT100, PT1000, current loops,
thermal elements, VDO sensors, MotoMeter for engine temperature and oil pressure etc.). For each
analogue input, two threshold levels can be set to trigger an alarm.
8.3.8.
Mains CB tripped
The mains circuit breaker can be monitored for automatic tripping (e.g. by an installed over-current
tripping device). The alarm is internally triggered if no feedback signal M AINS CB IS ON is detected after
running out of the mains CB closing pulse.
Furthermore it can be selected whether the engine should start and take the load or not (according to
VDE standard 0107) in the operation modes AUTO or TEST. The alarm must in this case be cancelled
for switching back to mains supply after the switch-back delay.
8.3.9.
Mains CB does not cut off
The alarm occurs when the mains CB is not off two seconds later after the Off-command. This alarm
can control a relay by which an additional mains coupling breaker can be switched off to allow the
generator to supply the consumers.
8.3.10. Generator CB tripped
The generator circuit breaker can be monitored for automatic tripping (e.g. by an installed over-current
tripping device). Additionally the mode WARNING/SHUTDOWN must be programmed for this alarm. The
alarm is internally triggered in case no feedback signal G ENERATOR CB IS ON is detected after running
out of the generator closing pulse.
8.3.11. Generator CB does not cut off
The alarm occurs when the generator CB is not off two seconds later after the Off-command. The
genset gets an internal start command and by this keeps the engine running and the generator CB
remains on.
The engine stops when in this case a shutdown alarm occurs. An additional generator coupling
breaker can be switched off by a programmed relay to prevent that the engine is operated with reverse
power.
8.3.12. Alarms of the voltage monitors
An alarm is announced if a monitored voltage or frequency of mains or generator is out of its range.
The alarm itself has no influence of the actual voltage or frequency monitoring. That means, if the
monitor has stated a failure and triggered the alarm and later on the monitored function is again within
its limit, the alarm is still present until it is cancelled. For the internal controlling however, the actual
state is used which means, that the monitored function is effective as NORMAL.
8.3.13. Monitoring of the currents
The generator currents can be monitored for
 overcurrent (e.g. 110 %)
 short-circuit (e.g. 300 %)
 unbalanced currents and
 thermal overload.
The Response Diagram for Thermal Overload, is shown further below.
8.3.14. Synchronisation failure
A timer is started when the synchronisation begins. An alarm is triggered if no synchronisation has
happened when this delay time is up. It is programmable if in this case a changeover with a break is
done or if the synchronisation remains on.
8.3.15. Load controller failure
An alarm is indicated when after a pre-set time the actual load has not matched the pre-set load value
(the actual load has to be at least once inside the dead zone). The genset can be stopped or a peak
load command can be removed in this case.

8.3.16. PF controller failure
An alarm is indicated when after a pre-set time the actual PF has not matched the pre-set PF (the
actual PF has to be at least once inside the dead zone). The genset can be stopped or a peak load
command can be removed in this case.
8.3.17. Reverse power
The generator CB must be switched off if the engine fails in parallel operation.
8.3.18. Running hours till Maintenance elapsed
The remaining running hours till the maintenance of the engine is shown in S ETPOINTS. A warning
alarm (if programmed) is given if the time period has elapsed. The counter for the time period till the
next maintenance must be set after the first one is done. This is only possible with ParaWin by
authorized persons. In case the goodwill period is set to 0 hours, this counter will stop at zero hours
and not show negative hours when the period is exceeded.
8.3.19. Maintenance period exceeded
An additional alarm (if programmed) occurs if the normal period and the additional goodwill period are
over. The reset is only possible for authorized persons. No alarm will occur in case the goodwill period
is set to 0 hours. This alarm can only be reset by the supplier!
9.
Mains Failure Protection in Parallel Operation
The mains voltage is monitored according to the limits of the VDE-AR-N 4105 or E VDE-AR-N 4105.
In addition, the voltage controller can be enabled for standard emergency power operation. This
applies to VDE-AR-N 4105 only. Due to the reduced tolerances of this standard, sensitive consumers
are safeguarded against too large deviations.
After parallel operation is established, the parameterised time elapses before the monitoring is
activated. This allows voltage, current and frequency to settle after the synchronisation. Should
subsequently a mains failure be detected, the mains switch is instantly set to OFF, and the standard
mains voltage monitor to Undervoltage. In this case, the parameterised delay for the mains voltage
monitor is disabled. Depending on the actual operating mode, the genset switches to idle emergency
mode or shuts down.
Even a brief interruption of the mains triggers the voltage monitor’s delay to run after the mains
voltage has recovered. According to the genset’s operation mode, it synchronises to the mains, or – in
case of genset standstill – the mains is switched on again. All below-listed additional functions can be
enabled or disabled for mains failure detection. This applies to the VDE-AR-N 4105 only.
9.1.
Monitoring Deviations in Voltage and Frequency
This monitoring can be enabled as a supplement to the requirements according to the VDE-AR-N
4105. After each measurement, voltage and frequencies values of the mains are stored and compared
to the previous values, even if the systems are not running in parallel. If in parallel operation, the
difference between the previous and current value (du/dt, df/dt) exceeds the parameterised value, this
is indicated as a mains failure. These measurements allow large deviations in voltage or frequency to
be treated as mains failures.
9.2.
Vector Shift
This monitoring can be enabled as a supplement to the VDE-AR-N 4105. The time duration of the
present voltage period is compared to the previous one. A deviation is converted to degrees. This is a
measurement of a vector shift. If the deviation exceeds the parameterised reference value, it is most
likely that a mains failure has occurred.

9.3.
Sealing the Setpoints
Inside the KEA, on the middle PCB – see Controller_PCB further below – you will find a jumper. If you
remove this, you will no longer be able to modify the following parameters:
 Mains failure if du/dt > … Hz
 du/dt enabled
 Mains failure if df/dt > … Hz
 df/dt enabled
 Mains failure if vector shift > … degrees
 Vector shift enabled?
If the jumper is removed and the KEA cover sealed, the setpoints you have entered cannot be
changed. Setting the mains voltage monitoring to 110 % according to VDE-AR-N 4105 is only
modifiable with ParaWin and password. All other limits are fixed.
9.4.
Mains Failure Protection according to E VDE-AR-N 4120
On the low-voltage side of a medium-voltage system, the monitoring proposes deviating functions for
switching off the generator. These requirement are met by KEA 201 SPL03 as of version 9.

Mains Reference Load Control Operation
When the specified mains reference load is exceeded, the genset starts, but not until after a time
delay (max. 240 sec.) to suppress unnecessary starts. Upon parallel connection of mains and
generator, the controlling is based on a parameterised reference load.
The mains reference load must be larger than or equal to the difference between the genset’s stop
loading and the starting point.
As soon as the consumer load falls, the generator output is reduced in order to maintain the parameterised load level at its reference. If the generator output falls below the generator power setpoint, the
start command to the genset will be cancelled – after a delay. The genset unloads to the minimum that
is set and then shuts down.
Now the mains reference load rises by the amount of the aborted genset power. Hence, select the
parameter values so as to ensure the starting point is not immediately exceeded once again.
In order to protect against return feed into the mains, a limit is provided. If this is fallen short of, the
genset is immediately turned off. Always select the parameters so that the aborted power does not
cause the starting point to be exceeded. This signal can be parameterised as an error message.
High and Low-Tariff (HT and LT)
The starting point of the maximum mains load and the succeeding control can be set differently for
high and low-tariff periods. Likewise, the starting and ending times of the low-tariff period can be
entered. This also allows the load control to be switched off during the LT periods.
Furthermore, for both periods, the power control can be switched off via a switch on the relay unit.
The power limitation according to VDE-AR-N 4105 is valid for parallel operation, provided the monitoring is enabled in ParaWin.

11.
Peak Load Operation Mode
1. The genset is started by a peak load command. If the genset is already running in TEST mode,
the system switches to parallel operation.
2. After parallel operation is accomplished, the internal power and PF controller is enabled and the
generator loaded. During the parallel operation, the internal power and PF (cos φ) control unit
is enabled and the generator loaded. The internal power and PF control is described further
below.
3. After the peak load command is disabled in AUTO mode, the genset is unloaded – and at a load
of 10 % of the generator switched off.
If the peak load command is given TEST or M ANUAL mode, you should switch back to the AUTO
mode to allow all following automatic processes to run.
The KEA 201 can detect a power failure during peak load operation. The KEA will then directly switch
off the mains, thus immediately shifting to emergency power operation.
After mains recovery and elapsed switch-back delay, the genset will synchronise with the mains. A
pending peak load command will cause the system to return to mains parallel operation – or switches
off if there is no start command.
12.
Mains Operator’s Load Levels
The mains operator is to specify the maximally allowed load in the following steps: 0%, (stop) 30%,
60%, and 100% (full load). For this, two terminal inputs are provided:

Enabling Mains Parallel Operation
13.1.
Description
The start is enabled if for at least 60 sec. the following is met:
 Frequency in the range 47.5 Hz - 50.05 Hz
 Voltage in the range 85 % - 110 % of UNOM
In addition, a percentage load of 30, 60 or 100 % must be specified.
If the genset operates in parallel with the mains, the mains failure monitoring, power and PF controlling operate according to the VDE-AR-N 4105. This can be supplemented with the internal vector
shift relay.
The line-to-line voltages are to be calculated from the phase-to-neutral voltages. For this, clockwise rotation fields at the measurement inputs are mandatory, the mains and generator monitoring for the isolated operation thereby switched off.
The switching points of the VDE monitoring system can be changed via a special password and
can also be sealed.
After a power failure, the protection against overvoltage (>U, averaged over 10 min.) is continuously determined until measurements of most-recent 10 min. are available. Consequently, if for
instance the value averaged over the first 3 min. already exceeds 110 % of the nominal voltage, the
mains failure is instantly detected – rather than not until after 10 min.

The settings according to VDE-AR-N 4120 are listed forth above.
For frequencies in the range 47.5 Hz – 50.00 Hz, a separation in consequence of a frequency
deviation is not permitted.
For the 5 most-recent events, date and time are stored, readable via the USB connection. Apart
from the average U>, all switching points are fixed.
By setting different thresholds for the mains and the generator monitor in parallel and emergency
operation (incl. sprinkler operation) according to VDE-AR-N 4105, you will be able to narrow the
limits.for emergency operation Please note that after a mains failure and switching to emergency
operation, the frequency and voltage control must under certain circumstances quickly bring the
system back into the specified limits.
13.2.
Setpoint for Power
The setpoint for mains parallel operation can be predefined:
 as an analogue signal, channel 4
 via a ZLT
 or as a parameterised fixed value.
An external setpoint value is stated as per mill of the nominal value, and the fixed value is stated in
kW. If the analogue channel is used, the minimum and maximum reference value are to be parameterised accordingly.
14.
Mains Recovery in Peak Load Operation
The start is enabled if the following is met:
 Frequency in the range 47.5 Hz - 50.05 Hz
 Voltage in the range 85 % - 110 % of UNOM
The delay after a power failure that lasts longer than 3 sec. is at least 60 sec. For power failures
lasting less than 3 sec. (short-time interruption), the synchronisation process can start after just 5 sec.
15.
Power Control
Via two inputs, the mains operator is to set a power limitation, the respective percentage restriction configurable. The reduction of the enabled amount of power takes place within a minute. For
the frequency range 47.5 Hz – 50.2 Hz, there is no further limitation of the power emitted.

If the frequency is equal to or higher than 50.2 Hz, it is not permitted to increase the power.
Instead, the present power level (at 50.2 Hz) is held.
Should the frequency still increase, the setpoint value of the power controller transforms into a
linear function with a slope of 40 % pro Hertz of the value at 50.2 Hz until it is switched off at 51.5
Hz, i.e. maximally reduced by 52 %.

If the frequency decreases, the power is increased according to the specified gradient until it
reaches the level at 51.5 Hz.
If the frequency still decreases, the genset can be operated with the enabled power level. In this
case, an increase in power will occur in steps of 10 % of the enabled power per minute. This is
followed by standard controlling.
Upon mains recovery, the power is increased in steps of 10 % per minute until it reaches the
required level. This is followed by standard controlling.
16.
Controlling Reactive Power
The VDE-AR-N-4105 specifies a characteristic curve or a fixed factor for the PF (cos φ). After a
start, the amount of reactive power is reached within 10 minutes. Values for the characteristic curve
are reached within 10 sec.
A standard curve specifies: Load in the range:
 0 % - 20 %: setpoint for cos φ = -/+ 0,9
 20 % - 50 %: setpoint for cos φ = -/+ 1.0
 50 % - 100 5: setpoint for cos φ linear in the range

Sprinkler Operation
The following functions are provided for operation of an electric sprinkler pump:
 Set all alarms as warning ones
 Start sequence with 10 (can be set by customer) start attempts,
 For the run-up of the sprinkler pump: pause or no pause for the emergency consumers,
 You can select when the sprinkler is no longer required, if the Sprinkler operation is cancelled after
the COOLING DOWN PERIOD AFTER SPRINKLER or is manually switched off.
The time stage for the COOLING DOWN PERIOD AFTER SPRINKLER CAN be set from 10 to 2400 seconds.
The sprinkler operation is not terminated automatically but must be ended manually if this stage is set
to 0 seconds.
In this is the case, the OFF mode indicator flashes.
The genset can now only be stopped via IMMEDIATE STOP or the mode OFF.
The pause duration of the emergency supply for the run-up of the sprinkler pump can be set from 0 to
24 seconds. The emergency consumers are not switched off if it is set to 0 sec.
The consumers are switched to generator supply if during the sprinkler operation a mains failure or a
remote start with load transfer occurs. The emergency consumers are switched back after expiry of
mains recovery delay when the mains voltage is restored or the remote start command is cancelled.
The sprinkler mode prevents that the genset is switched off or shut down due to an alarm. If a
shutdown alarm is triggered, however, the common alarm SHUTDOWN is issued.

Terminals 1–14: Input for alarms signals.
Terminal 15: Feedback signal: MAINS CB IS OFF.
An auxiliary contact (NC) of the mains CB (or contactor) is connected to this terminal. It shows the

Terminal 16: Feedback signal: GENERATOR CB IS OFF.
An auxiliary contact (NC) of the generator CB (or contactor) is connected to this terminal. It shows
the position of the breaker. The control unit is fitted with an interlocking circuit that prevents the
mains from switching on (without synchronising) as long as the generator supply is on.
Terminal 17: Operation mode selection is locked.
The selection of the operation modes by the push-buttons will be locked if a signal is applied at this
terminal. A key-operated switch, to prevent the selected mode from being changed by unauthorised
persons or by mistake, could perform this.
Terminal 18: Remote start with Load Transfer.
If an L[-] signal is connected, and the system is running in operation mode AUTO, the genset starts
with switchover to generator operation.
If the system is in TEST mode or has been started in AUTO mode via the command START WITHOUT
LOAD TRANSFER, the generator is automatically switched on.
If an L[-] potential is not applied – command START WITHOUT LOAD TRANSFER must not be displayed,
the generator will – upon the switch-back delay – be switched off, and the genset turned off – after
the delay.
Terminal 19: IMMEDIATE STOP.
The signal can be parameterised as normally-closed or normally-open – KEA display, Group 6,
PARAWIN, under ADDITIONAL PARAMETERS . The genset will be immediately shut down if a signal is
applied to this terminal. The control unit will be locked for any further starting attempts. To reset the
control unit, the operation mode has to be set to OFF. Resetting is only possible if the signal is no
longer connected, otherwise the indicator AUTOMATIC LOCKED would remain on.
Terminal 20: Overlapping synchronisation active.
If an L[-] signal is connected here, the load transfer between mains and generator supply (in operation mode TEST) and the re-connection to mains supply (in operation mode AUTO) will take place
without interruption by means of synchronized change-over.
If an L[-] potential is not applied, the change-over between mains and generator supply will take
place with configured breaks.
Terminal 21: Peak Load Command.
If an L[-] signal is connected here and you have selected the operation mode AUTO, the genset
starts and synchronises to the mains. It is gradually loaded according to a drive-up ramp. After the
peak load command is cancelled, the genset is unloaded, and – if the power falls below the load
relief value – the generator is turned off.
Terminal 22: Disabled regulation of mains reference load
Terminal 23: Sprinkler mode.
When an [L-] signal is connected to this terminal, the genset starts without changing over to generator supply, and all alarms serve only as warning ones – except for overspeed (only applicable if an
electronic speed controller is in use). The generator switch stays on, it can, however, be parameterised to switch off in the events of generator short-circuit or overload.
Terminal 24: Start enable input.
Any starting attempt emitted manually or automatically will be interlocked as long as there is no [L-]
potential connected to this terminal. It is therefore possible to incorporate relevant pre-start conditions before a signal is given to the starter motor for cranking. If this function is not used, a wire
jumper from [L-] to terminal no. 24 must be connected.
This function does not meet the requirements of the German Standards DIN VDE 0107, as a running genset will not be shut down; this function only protects the engine before start-up.
Terminal 25: Remote start without Load Transfer.
When a command is issued to this terminal, the genset starts in the AUTO mode without the generator being switched on. Only if a command is also issued to terminal 18 (Remote start with Load
Transfer), the generator breaker will be switched on. To switch off the generator breaker again,
both signals (terminals 18 and 25) must be cut!
Terminal 26: External command :GENERATOR OFF
If a command is applied here, the generator CB is immediately switched off and remains off as long
as the signal is applied.
