The KEA 211-NC3-1-8 automatic system replaces the NC3-1-8 automatic system distributed by SEG. All
functions of the replaced automatic system are fulfilled. In addition, there are other useful functions. The
contact loads of the output relays correspond with those of the replaced automatic system or can support
higher loads. All functions and settings can be parametrised using the Kuhse PARAWIN software. All func-
tions allocated to the genset are included for sprinkler operation (according to VDS 2100-22). The automatic
system is delivered with a standard parametrisation for the replacement of an NC3-1-8. The installation and
warning information must be observed.
Additional functions are:
17 relays, 14 of them can be parametrised on many functions.
Speed measurement via pick-up (no longer possible via speedometer generator) with thresholds for start-
ing, ignition, nominal and overspeed,
10 alarms, parametrisable for operating current and standby current contacts, warning and stopping,
switching off generator or not
All LEDs of the alarms can be used as operating displays if they are not used for alarm generation.
Alarms 9 and 10 can also be delayed by the contacting and are also active in the OFF position (e.g. as a
leakage warning system).
The alarms are labelled by easily replaceable paper strips.
The voltages and frequencies are monitored for underscoring and exceeding. In the event of an error,
alarm messages can be displayed in this context. In addition, the rotating field of the mains voltage can
be monitored.
Enhanced functions for the control of circuit-breakers and operation with transfer synchronisation.
The operation of the automatic system is simple and uncomplicated, as it is carried out directly via the usual
keys for all KUHSE automatic systems. Deviating functions are marked in blue.
Subject to technical change without notice.

INSTALLATION AND WARNING INFORMATION
All information in this manual must be observed.
The connection of the unit must be carried out carefully, as a wrong connection could lead to the
destruction of the unit. The connection regulations must be observed.
The PE(N) must be connected to the point marked with the earthing symbol.
The installation and commissioning must only be carried out by sufficiently qualified personnel.
Applicable regulations, especially those of the VDE must be observed.
The parametrisation of the unit must be carried out in such a way that endangerment of persons
and property is excluded.
If the battery has to be disconnected, the charging unit must be switched off.
The battery negative potential must be earthed at the input terminal on the switchboard. The
minimum cross-section is 10 mm2.
The supply voltage (12 or 24 V DC) is selected using a switch located on the circuit board under
the hood.
If the supply voltage of the automatic system was switched off, it must only be switched on again
after approx. 20 seconds.
All the coils must be provided with a freewheeling diode (for DC voltage) or with a quench circuit
matching the inductance of the coil. This also applies for all relays and inductances that are used
differently in the switchgear or are externally controlled.

NOT IMPLEMENTED OR MODIFIED FUNCTIONS The optional connection of a tachometer generator is omitted, instead the input for a pick-up with an evalua-
tion of the ignition, starting, nominal and overspeed is intended as standard.
The START INHIBITOR input is only effective prior to a start and releases it as soon as a signal is no longer
pending. If the signal ceases during the operation, a running genset is not switched off.
The remote control of all operating buttons is reduced to the operating mode selection and the functions
HORN OFF and ALARM OFF.
The EMERGENCY START is omitted.
DISPLAYS AND KEYS
Functions of the keys
Selection of the operating mode
The operating modes are selected by four keys. The selected operating mode is displayed by LEDs. The keys
can be locked via an input (e.g. via connection of an external key-operated control switch), so that the unau-
thorised or random change of a defined operating mode is prevented. The operating modes described below
can be selected using the keys.
START key
The motor can be started in the MANUAL operating mode by actuating this button. If the motor needs to be
preheated, press the MANUAL and START keys at the same time. Actuating this key is ineffective when the
machine is running or also in any other selected operating mode.
LED TEST key
The functioning of all LEDs of the automatic system can be tested by this key. To control other signal lights
of the switchgear during the lamp test, a relay can be parametrised to this function.
ALARM OFF key
Due to an actuation impulse of this key, the acoustic signal issued by this alarm is deleted, the message
continues to flash. After a second confirmation, it changes over to continuous lighting. After the cause of the
error has been eliminated, the LED display is deleted by actuating the button again.

TA211NC3-1-8 UK - 5 / 21 - 08/28/17
General displays
The two upper rows of the LEDs provide important information on the operating processes and error mes-
sages. The displays described below are intended as standard.
Monitoring on
Using this green LED (after the genset start-up), the release of the operating-dependent delayed alarms is
signalled. As soon as the motor has started up, this LED flashes until the monitoring is released. The moni-
toring is switched off if there is a total failure of all "running" criteria, the automatic system is locked.
The display goes out at the beginning of the shut-down process.
Automatic system locked
This LED indicates that the automatic system is locked for further start attempts and thus genset operation is
inhibited. The automatic system is unlocked by selecting the OFF operating mode (after eliminating the cause
of the error). To do so, any actuated external Emergency OFF buttons must also be unlocked. The display is
switched on in continuous light operation by a signal on the Quick Stop input (Emergency Stop), or together
with such alarms that lead to the shut-down of the genset.
Start control
The LED start control indicates a pending start. The function
is similar to the charging check of a car. Furthermore, it shows if the
start prerequisites have been fulfilled. It is switched on for an automatic start,
or for selection of the MANUAL operating mode (in expectation of a manual
start). Any auxiliary drives and the start prerequisites
are switched on, the display flashes in the normal mode.
As soon as the auxiliary drives or the starting conditions release the start via the
START INHIBITOR input, the display changes over to steady light,
as long as either the generator or a Pick-up indicates that the
genset has started up.
The display goes out as soon as the genset exceeds the ignition speed during start-up
(detected by the D+ signal of the generator
or by the revolution transmitter signal according to the parametrisation). It continues
as a steady light again if the pending signals fail during the operation.
The display flashes in quick succession if the time for the start release
has expired without the start being released.
False start / Motor malfunctions
This alarm is controlled by three criteria. That's why this message has expired needs to be interpreted. The
message is controlled
FALSE START. If the genset has not started at the end of the starting program,
the alarm is issued. It is displayed with a steady light (without flashing),
the automatic system is locked.
MONITORING FAILED. If all signals for the
speed measurement (generator voltage, generator or Pick-up) fail during operation,
this alarm is issued. It is displayed with two short flashing impulses,
the automatic system is locked.
MOTOR DOES NOT SWITCH OFF If the genset still runs after the stop time has expired,
this alarm is issued. It is displayed by normal flashing,
the automatic system is not locked.
BELT RIP. This alarm can be released or deactivated. If
the generator does not supply voltage with an available generator voltage,
this alarm is issued. The display flashes in quick succession. It can be parametrised
if stopping is carried out immediately or if the
automatic system is to be locked only after a normal stop.

Mimic diagram / Voltage monitor
The mimic diagram displays the mains infeed, the generator, the mains and generator circuit breakers and the
busbar. Green LEDs below the mains or generator symbol indicate if the respective voltage is within the
limits. These LEDs flash as soon as the voltages are within their limits, but the release time has not yet
expired.
The positions and any messages of the mains and generator switch are displayed by green LEDs below the
OFF keys (O). They indicate the following conditions:
In the event of a BREAKER TRIPPING SIGNAL (if parametrised), the respective LED
flashes like a normal alarm (slow flashing with equally long light and dark phases).
The LED briefly flashes once during the synchronisation of the switch.
If the SYNCHRONISATION DISRUPTED alarm (if parametrised) is pending,
the LED briefly flashes twice. However, it is overridden by the MAINS IS ON
or GENERATOR IS ON signal.
If the SWITCHING OFF IS HINDERED, it flashes with short pulses.
If the mains or the generator is switched on, the LEDs show
the position of the switch with a continuous light. Thus, it overrides the above
messages, as the switch was finally able to switch on.
FUNCTIONS
Start release / Start inhibitor
The auxiliary drives (e.g. space fan, shutters) and the start preconditions, which are only required for the start
phase (e.g. prelubrification pump), are immediately switched on in the MANUAL and TEST operating modes,
and switched on in AUTO with a start command. The switch-on duration of the start preconditions (para-
metrisable) is time-limited. They are switched off after start-up of the genset, the auxiliary drives remain
switched on during the operation and a parametrisable idle time. The functions can be parametrised to output
relays. If all required criteria are fulfilled, the START INHIBITOR signal is taken away and thus the START
RELEASE is given.
Attention: The function, which shuts down a running genset by taking away the signal during operation, is
not implemented.
Start release
After switching on the start preconditions and auxiliary drives, the START CONTROL display flashes as long
as no start release is required. The start is inhibited as long as the L- signal is available on the START
INHIBITOR input.
Start release / Start inhibitor for sprinkler operation
For the start requirement for sprinkler operation, the start is released immediately or, if important precondi-
tions are necessary, after a (short) parametrised time, independent of the signal to the START INHIBITOR
connection. The external input signal is ignored.
Remote selection of the operating mode
The operating modes OFF, MANUAL, AUTO and TEST can be selected via three contacts if the operation
selection on site (connection C22 or terminal 29) is locked by L-. The MANUAL remote selection is selected
by simultaneous signal transmission to F9 and F5 (terminals X2/4 and X2/6). In order to select a new operat-
ing mode, all inputs must first be released and the new function must then be specified.
Acknowledging external error and horn off
These two orders are summarised into a REMOTE ACKNOWLEDGEMENT. A steady signal only gives an order
so that L- must be applied several times for switching off the horn and deleting the alarms.
The first impulse (L-) to connection F8 (terminal 32) switches the horn off. A new alarm would switch it on
again.
A second impulse deletes the alarms if they are released by the parametrisation for this (e.g. smoke detectors,
etc. should not be remotely acknowledgeable). The MAINS and GENERATOR CIRCUIT BREAKER TRIPPED, and
MAINS and GENERATOR OFF HINDERED and BELT RIP are also deleted.
3
TA211NC3-1-8 UK - 7 / 21 - 08/28/17
If the alarm contact is still pending, remote acknowledgement of this alarm is not possible. If the automatic
system is inhibited by the QUICK STOP input, it cannot be unlocked by the remote acknowledgement as long
as the signal is pending, but only on site by release of the input signal.
Transfer synchronisation
The transfer synchronisation (if the additional units necessary for frequency adjustment, possibly voltage
adjustment and switch-on command for synchronism are available) is carried out, deviating from the original
wiring of the NC3. Thus, the procedure is clearer and the controller safer. A signal is issued to switch on the
synchronisation system. Furthermore, contactor and circuit breaker must be switched on via the switch-on
pulses issued by the automatic system.
The synchronisation duration (parametrisable) is monitored. If no synchronisation has been carried out, it is
possible to select whether a switch should be carried out with an interruption or whether the synchronisation
attempt should be continued. The D1 connection (terminal 33) can be used to select whether a switch should
be carried out with or without an interruption.
The transfer synchronisation is only released if the mains and generator voltage monitors do not show any
false voltages.
Attention: This function assumes a wiring change of the mains and generator circuit contactor or switch. The
procedure is thus clearer and the controller safer.
OPERATING MODES Off operating mode
The OFF position is automatically selected (reset function) during the application of battery voltage in order
to prevent the triggering of an unintentional start-up. When switching to OFF FROM ANOTHER OPERATING
MODE:
– A genset operation is immediately ended
– Previously displayed error messages, except the fault messages 9 and 10, are deleted as long as their
alarm contact is still active
– The automatic system is unlocked. However, if the QUICK STOP INPUT (EMERGENCY STOP) is still active,
unlocking is not possible; the AUTOMATIC SYSTEM LOCKED message remains.
Manual operating mode
Start and stop
The auxiliary drives and start preconditions are immediately switched on. After the start release, the genset
can be started up via the START button. In order to switch off the genset, the OFF or (in the event of missing
start with load) AUTOMATIC operating mode must be selected.
Using the MAINS OFF (O) key, the mains can also be switched off when the genset is at a standstill, the
MAINS ON (I) key is used to switch it on again for error-free mains voltage. The motor can be started using
the START key.
Attention: A button for manual stopping is not intended.
Heat treatment
By pressing the MANUAL and START buttons at the same time, the starter is not actuated, but the heat treat-
ment is switched on. If the MANUAL button is then released or only the START button is pressed, the starter is
switched on. For the AUTO and Test operating modes, the start delay is used for the heat treatment.
Switching mains/Generator
If the generator voltage with its voltage and frequency values is within the value limits, the generator can be
switched on. The switching between mains and generator operation and vice versa is always carried out with
the parametrised switching breaks if the GEN-ON or MAINS ON key is used.
It is also possible to first switch off the mains or the generator with the respective OFF key and then switch
on the generator or the mains with the respective ON key. Thus, it is possible to disconnect the busbar from
the power supply. The actuation of the ON keys remains ineffective if the voltage of the selected system
(mains or generator) does not lie within the specified limits.
3
TA211NC3-1-8 UK - 8 / 21 - 08/28/17
All switching processes are only carried out manually and not automatically. Even a remote start command
does not lead to automatic switch-on of the generator. Also, the mains is not automatically switched on if an
error message occurs during generator operation (e.g. GENERATOR OVERCURRENT), which switches off the
generator.
Auto operating mode
Start with generator loading
The automatic start can be carried out by four parametrisable functional types. Thus, all possibilities of the
NC3-1-8 are enabled in a simple manner.
(1) Start only via the internal mains voltage monitor.
(2) Start only by the external start command with load.
(3) Start only if the internal mains voltage monitor and simultaneously the external start command with
load command issued.
(4) Start only if the internal mains voltage monitor or the external start command with load issues the
command.
Attention: For start triggering (3), the start is carried out when the internal voltage monitor indicates a power
failure and the remote start is also issued. If only the remote start is removed, but the power has failed, the
genset is switched off, however it is not switched back to the failed mains. The switching-on of the mains is
carried out at the end of the power failure.
In the event of a missing start command (see start triggering (1) to (4)), genset is in standby mode. If the
entered limit values (according to the parametrisation) are no longer observed for the voltage or frequency of
the internal voltage monitor, the power delay is recognised with a delay. The green LED below the mains
symbol after expiry of this parametrised delay time. The external voltage monitor input has no influence on
the green voltage display.
The genset is started according to the required start function. The FALSE START/MOTOR ERROR message is
issued and the automatic system is inhibited if the genset has not started at the end of the start program.
After the start-up of the genset, the mains is switched off and the generator is switched on as soon as the
nominal generator voltage and frequency are reached after a switching break (parametrisable). If the mains is
defective, with respective parametrisation the switching-off can already be carried out prior to the start in
order to protect the consumer.
After normalisation of the mains voltage and release of the external input (according to the required function
type), a delay time (switch-back delay) elapses before the generator is switched off and switched on again
after a switching break.
In order to prevent heat congestion, if it was loaded the genset continues to run unloaded for the adjusted idle
run time and then is shut down.
For the operating modes (2) and (4), the generator operation is switched over without interruption for intact
mains voltage and released transfer synchronisation.
Attention: If an alarm occurs that switches off the generator while the idle time is not acknowledged, the
automatic system is locked as an automatic emergency power operation is no longer possible.
Start without generator loading
If no start with load is pending, the genset can be started by
the sprinkler requirements or
the start without generator loading input.
A switchover to generator operation is only carried out with a simultaneous start command with load or
power failure. If these start commands are issued alone, the genset runs unloaded. A mains parallel operation
such as for the NC3-1-8 is not possible, as a power, a cos-phi controller and a power cut protection are
necessary for this. Here, the Kuhse KEA 201 SPL automatic system should be used, which fulfils all func-
tions (power failure protection, synchronising unit, synchronising locking unit, power and cos phi controller)
according to the VDE regulation AR-N 4105.
Mains circuit breaker tripping
The automatic system can be parametrised in such a way that the start and the switching to generator opera-
tion can also be carried out if the mains switch fails due to an error. In this case, the genset runs automatical-
ly and takes over the substitute power supply. The green MAINS IS ON LED flashes for the display of this
error.
3
TA211NC3-1-8 UK - 9 / 21 - 08/28/17
For switching back to the mains, the MAINS CIRCUIT BREAKER TRIPPING message must be deleted (ALARM
OFF button). For problem-free mains voltage, the automatic system switches back to mains operation after
expiry of the switching-back time.
Test operating mode
After button selection to the TEST position, the start program is triggered. If the generator voltage with its
voltage and frequency values lies within the parametrised value limits, the mains can be switched off and the
generator can be switched on with the GEN-ON (I) or MAINS OFF (O), or the generator can be switched off
and the mains can be switched on with MAINS ON (I) or GEN-OFF (O). If the transfer synchronisation func-
tion (L- to connection C20, or terminal 33) is selected, switching over to this operating mode is carried out
without interruption.
If a start command with load or MAINS CIRCUIT BREAKER TRIPPING (if parametrised) during test operation,
operation is switched over to generator operation. Then, it is not possible to manually switch off the genera-
tor circuit breaker. Manual operation of the switch is only possible after removal of the start command (pos-
sibly also deletion of the MAINS CIRCUIT BREAKER TRIPPING alarm) and expiration of the switching-back
time.
In order to switch off the genset, the OFF or AUTO operating mode must be selected (in the event of missing
start with load command).
SPRINKLER OPERATION A L- signal on the C19 input (terminal 31) triggers a start without load, in order to supply an electrical sprin-
kler pump. The following functions are intended for the operation of an electrical sprinkler pump:
Switching of all switching-off alarms (overspeed alarm remains switched off for electronic speed sensor,
demand VDS 2100-22) to warning
Optionally, the inhibition of the generator switching-off function for GENERATOR OVERCURRENT, for
example
Start program to 6 (parametrisable) start attempts
For ending the sprinkler requirement: Cancellation of sprinkler operation after the SPRINKLER IDLE TIME
or only manual shutdown (demand VDS 2100-22)
For the duration of the acceleration time of the sprinkler pump: Switching off the emergency power
consumers or no interruption of the emergency power supply.
The supply of the sprinkler pumps is usually taken care of directly by the generator and thus prior to the
switch to the emergency power consumers. In the event of the emergency power failure, the consumers can
be switched off for a parametrisable period of time in order for enough energy to be available for the acceler-
ation time of the sprinkler pump. Furthermore, it is possible to parametrise that the consumer switches re-
main switched on or switch off in the event of an overload on the side of the consumers.
Sprinkler operation is automatically cancelled after the sprinkler requirement is removed after an entered idle
time or can only be ended manually (demand VDS 2100-22). If the automatic system is parametrised for
manual shutdown, the LED of the OFF operating mode flashes as soon as the sprinkler input is free. Stopping
can then be carried out via the OFF operating mode (or always via Emergency Stop).
If stopping should commence after the idle time and the Off operating mode is selected, the generator
switches off and is switched back to mains operation if the mains voltage is intact. However, the genset
remains switched on until the sprinkler input is free again. In this case, if stopping should commence inde-
pendently of the sprinkler input, the Emergency Stop must be actuated.
ERROR MESSAGES / PROGRAMMABLE OPERATION DISPLAYS Any of the 10 LEDs can either display an error message or be parametrised as an operation display.
Use as an operation display
These displays are independent of the selected operating mode. Thus, they can be used as displays of opera-
tional conditions via contact inputs or as internal flags of operation conditions as normal signal lamps. The
PARAWIN software is required for parametrisation. The flag list contained in it can be found further down.
Use as an error message
The automatic system includes the possibility of processing 10 alarms. The alarms are designated with
labelled text strips. The control is carried out by contact inputs or internal flags (overspeed, battery un-
dervoltage, mains or generator voltage error, etc.). The PARAWIN software is required for parametrisation.
3
TA211NC3-1-8 UK - 10 / 21 - 08/28/17
The flag list referenced in it is specified further down. For contact inputs, the respective alarm is triggered
with the closing (operating current circuit) or with the opening (standby current circuit) of the signal contact
against L-.
The alarms are basically divided into three groups:
Alarms that are only monitored delayed after start-up of the motor (e.g. LOW OIL PRESSURE). The release
can be recognised on the green MONITORING ON display.
Alarms that are also monitored when the motor stops (e.g. BATTERY UNDERVOLTAGE), except in the OFF
operating mode. They are designated as without delay.
The alarm messages 9 and 10 are always monitored, even in the OFF operating mode. They are used for
messages (e.g. LEAKS). The horn is not switched on in the OFF operating mode, but the alarms are not in-
cluded in the collective alarm. They behave like normal alarms if an active operating mode (so not OFF)
is selected.
The alarms are configured as follows:
Alarm is active or locked
Contact is in standby current or operating current
Delayed or undelayed monitoring
Warning or switching-off function
In addition for warning alarms: With or without generator switch-off and stop after idle time in automatic
operation.
Function and operation
The accruing of an error message is displayed by the LED flashing. At the same time, the acoustic signal (for
the entered duration) is controlled. With a pulse of the ALARM OFF key (or automatically after the entered
time), the acoustic signal is switched off. However, the LED continues to flash. If the value 0 sec. is entered
for the duration of the horn switch-on, no automatic switch-off is carried out: The horn remains switched on
until manually deleted.
Due to a second button actuation of ALARM OFF, the message switches from flashing light to continuous
light. Due to the necessary second acknowledgement, e.g. the switching off of the acoustic signal generator
after an automatic switch-off, it can be distinguished which error message has newly occurred.
The display is deleted after the error is eliminated after renewed actuation of the ALARM OFF key.
For messages that lead to the switching-off of the genset, the further operation is inhibited, displayed by
AUTOMATIC SYSTEM LOCKED. In order to unlock, the OFF operating mode (any actuated external Emergency
OFF buttons must also be unlocked) must be selected.
Attention: If the generator is switched off due to a warning alarm in automatic operation, the motor is
stopped after the idle time and the automatic system is locked.
Alarms 9 and 10
Both these alarms can be delayed from 0 to 240 sec. by the signal transmission, i.e. for the alarm contact to
issue an error, the signal must be pending for a parametrised time. Furthermore, both these alarms are also
effective in the Off operating mode (Off), but without switching on the horn. Thus, criteria (e.g. tank over-
filling, leakage warning) that always have to be reported can be monitored.
Internal error messages
The following alarms are created by the software. They can be locked or activated by the parametrisation
(the exception is the false start message, which is always active).
Error messages of the voltage monitor
The criteria of the voltage monitor, recognised as faulty, released for monitoring (<U, >U, <f, >f), can be
displayed. They can, individually or collectively, control an error message or only be displayed.
Overspeed
For the overspeed monitoring, either the generator frequency or the frequency of a pick-up is used (according
to the parametrisation). The speed threshold can be parametrised.

False start
This alarm is always active and cannot be locked. If the genset has not started after the parametrised start
amount (normal or sprinkler operation), the alarm is issued. The FALSE START / MOTOR ERROR LED is per-
manently switched on (without flashing), the automatic system is locked for further start attempts. The
automatic system is unlocked via the OFF operating mode, so that a new start sequence can begin.
Speed measurement failed
If all criteria for the speed recognition, and thus for the error monitoring fail (according to parametrisation;
available generator voltage, generator terminal D+, Pick-up), the FALSE START/MOTOR ERROR alarm is
triggered, the genset is switched off and the automatic system is locked. For the display, the LED flashes in a
quick rhythm.
However, if this alarm occurs during the sprinkler operation, the genset remains in operation, the monitoring
of the motor remains switched on
Generator failed
This alarm can be locked or released. If the generator is driven together with the cooling fan, a belt rip can be
recognised. With available generator voltage, the generator must also have a positive signal on the terminal
D+. If it ceases or is not pending with an available generator voltage, the GENERATOR FAILED alarm is trig-
gered after approx. 10 seconds.
This error is displayed by a flashing impulse of the FALSE START / MOTOR ERROR LED.
Motor does not switch off
If the motor still runs after the stop process has expired (switching off of the stop solenoid) or without re-
newed starting order, the stop process is repeated and the FALSE START/MOTOR ERROR message is displayed.
The automatic system is not locked, so that the genset can immediately switch to generator operation for a
start requirement (power failure or sprinkler requirement).
This error is displayed by a flashing impulse of the FALSE START / MOTOR ERROR LED.
Synchronisation fault
The duration of the synchronisation can be monitored. If no switching is carried out during the parametrised
time, the switching is carried out optionally with an interruption or continued further without interruption.
The parametrisable SYNCHRONISATION HINDERED alarm does not switch on the collective alarm or the horn.
If this is required, the function can be placed on one of the alarms from 1 to 8.
The MAINS IS ON or GENERATOR IS ON LED of the selected mode briefly flashes once during the synchroni-
sation of the switch.
If the SYNCHRONISATION HINDERED alarm (if parametrised) is pending, this LED briefly flashes twice.
However, it is overridden by the MAINS IS ON or GENERATOR IS ON signal.
Monitoring of mains and generator switches
These messages are displayed via the different flashing pulses of the respective ON LEDs. The following
four functions can be summarised, so that only one alarm or signal relay SWITCHING ERROR is seized if
required. The reason for triggering the alarm is displayed by the respective LED in the mimic diagram. It is
important to note that the error function of the ALARM Off is deleted with the first press of a button, but must
be acknowledged several times for deleting the alarm (see above).

The flag for the required summary is the summary of the digits 42, followed by the determined hexadecimal
number (always with the leading zero).
Example: The GENERATOR CIRCUIT BREAKER TRIPPED and GENERATOR OFF HINDERED functions should
trigger an alarm. The sum of the key figures is (4+8) =12. The table shows that the hexadecimal number 0C
results for the decimal number 12. Thus, 420C is parametrised as a flag.
Mains circuit breaker tripping
The alarm is internally controlled if no MAINS IS ON feedback is carried out after the mains switch-on pulse
has expired. After a mains circuit breaker tripped, the MAINS IS ON LED flashes like a normal alarm with
equally long light and dark phases, the acoustic signal is issued and the collective alarm message is switched
on. Due to the ALARM OFF, the first actuation switches off the acoustic signal and the message is acknowl-
edged with a second press of ALARM OFF.
According to the parametrisation, the genset starts if a mains circuit breaker trips in the AUTOMATIC position
and takes over the supply. In this case, the alarm must be deleted for switching back to mains operation.
After deleting has been carried out, mains operation is switched back to after the switching-back delay if the
mains voltage is intact.
Switching off mains hindered
The alarm is given if no MAINS IS OFF feedback is registered approx. 2 seconds after the switch-off com-
mand for the generator circuit breaker. In the event of emergency power failure, the genset is switched off
after the idle time, as the generator operation cannot be switched over. The MAINS IS ON LED flashes with
quick pulses. After the error has been rectified, the message must be deleted via ALARM OFF or by the selec-
tion of OFF operating mode.
Generator circuit breaker tripped
The alarm is internally controlled if no generator feedback is carried out after the GENERATOR IS ON switch-
on pulse has expired. After a generator circuit breaker tripped, the GENERATOR IS ON LED flashes like a
normal alarm with equally long light and dark phases, the acoustic signal is issued and the collective alarm
message is switched on. If the message is not acknowledged, the genset switches off after the idle time in
automatic operation.
Switching off generator hindered
The alarm is given if no GENERATOR IS OFF feedback is registered approx. 2 seconds after the switch-off
command for the generator circuit breaker. The genset includes a renewed start command and goes to gener-
ator operation. If a switch-off alarm occurs, the genset is now stopped. After the error has been rectified, the
message must be deleted via ALARM OFF or by the selection of OFF operating mode.
EMERGENCY STOP / EMERGENCY OFF (EXTERNAL) In order to trigger the Emergency Stop function, a pulse on the QUICK STOP INPUT (EMERGENCY STOP) is
sufficient. The input can be optionally switched (parametrisable) to operation or standby current. Thus,
independent of the operating mode:
the generator is switched off,
the genset is shut down,
the auxiliary drive is switched off,
the automatic system is locked for further start processes (display: AUTOMATIC SYSTEM LOCKED).
In order to unlock, the OFF operating mode must be switched. If the QUICK STOP signal is still pending, it
cannot be unlocked. The AUTOMATIC SYSTEM LOCKED display remains switched on.

Three additionally parametrisable signal relays, 35 DC, 1 Amp. They switch the joint signal of terminal 15
(optionally L+ or L-).
K15 relay: Terminal 12,
K16 relay: Terminal 13
K17 relay: Terminal 14.
The K15 and K16 relays can be used for the switch-on pulse of a mains and a generator circuit breaker. Here,
an auxiliary relay (with freewheeling diodes via the coils) should be used.
Information:
If freewheeling diodes are intended in the automatic system, the polarity of the contact voltages must not
be mixed up.
Deviations of the connection or of functions are marked here in blue.
Standard parametrisations of the relay are specified here in green.
All relays of the switchgear and of (also externally) controlled inductances must be equipped with free-
wheeling diodes or respective wiring in order to prevent switch-off peaks. Exceptions from this are the
relay outputs which are already equipped with freewheeling diodes internally. Please check these
measures.

PARAMETRISATION
Remote start / Start by internal mains monitor
The automatic start can be carried out by four parametrisable functional types. Thus, all possibilities of the
NC3-1-8 are enabled in a simple manner.
(1) Start only via the internal mains voltage monitor.
(2) Start only by the external start command with load.
(3) Start only if the internal mains voltage monitor and simultaneously the external start command with
load command issued.
(4) Start only if the internal mains voltage monitor or the external start command with load issues the
command.
Attention: For start triggering (3), the start is carried out when the internal voltage monitor indicates a power
failure and the remote start is also issued. If only the remote start is removed, but the power has failed, the
genset is switched off, however it is not switched back to the failed mains. The switching-on of the mains is
carried out at the end of the power failure.
Alarms and operation displays
The following parameters (excerpt from PARAWIN) are intended per display:
(1) No - LED 1: Display only, no error message (2) 3C08 - control via flag entry (3) AUWI - coding of the functions (4) No - error message without saving
Parameter (1) is set to <No>.
Parameter (2) determines the input signal. The following table shows the flag of the input terminals:
Connection to X1 Flag Connection to X1 Flag
Terminal 16 0201 Terminal 21 0240
Terminal 17 0202 Terminal 22 0280
Terminal 18 0204 Terminal 23 0302
Terminal 19 0210 Terminal 24 0304
Terminal 20 0220 Terminal 25 0308
The list with further possible input signals of internally derived flags is inserted as Annex A. The 3C08
entry in this example controls the alarm in the event of overspeed.
Parameter (3) determines the function (coding) of the error message. The following abbreviations are used:
A – operating current R – standby current
U – undelayed V – delayed
W – warning S – switch-off
I – generator remains on 0 – generator is switched off
For OPERATING CURRENT, the alarm is triggered if a contact is closed. For STANDBY CURRENT, the alarm is
respectively triggered if a contact is opened.
A DELAYED alarm is only activated after start-up of the motor and the parametrised delay MONITORING ON,
an UNDELAYED ALARM is also active during standstill of the motor. In the OFF operating mode, all alarms
except 13 and 14 are not monitored.
A STOPPING alarm stops the motor, switches off the generator and locks the automatic system, a WARNING
ALARM only shows the emergence of the alarm.
Furthermore, it can be parametrised for warning alarms if the generator remains SWITCHED ON (I) or
SWITCHED OFF (0) in the event of an error. If a warning alarm occurs in automatic operation, which shuts
down the generator, the genset is switched off after the idle time shut-down and the automatic system is
locked.
3
TA211NC3-1-8 UK - 18 / 21 - 08/28/17
Page 18 of 21
Parameter (4) determines whether the message should remain saved if the input signal has ceased or if it is
automatically deleted. The parametrisation of this function must be weighed up carefully. It only makes
sense for warning error messages that do not switch off the generator.
Example: This can be useful for the Battery undervoltage error message after several start attempts, for
example. The operator of the system is informed (as always) by the acoustic signal and the collective alarm
in the event that this message occurs.
The battery charging takes place and can be used again after a corresponding amount of time. As long as the
BATTERY UNDERVOLTAGE message (then actually no longer available) is pending, the collective alarm
would also be active and possibly inhibits the accruing of a more important error.
Alarms 9 and 10
Both these alarms can be delayed from 0 to 240 sec. by the signal transmission, i.e. the alarm contact issues
an error, the signal must be pending for a parametrised time. Furthermore, both these alarms are also effec-
tive in the Off operating mode (Off), but without switching on the horn. Thus, criteria (e.g. tank overfilling,
leakage warning) that always have to be reported can be monitored.
Error messages of the voltage monitor
The criteria of the voltage monitor, recognised as faulty, released for monitoring (<U, >U, <f, >f), can be
displayed. They can, individually or collectively, control an error message or only be displayed. For this, the
required error message (or only display, according to the parametrisation of this message) of the input flag
can be found in the following table. It is important to note that a message must be entered as WARNING and
DOES NOT SWITCH-OFF GENERATOR for mains errors, as otherwise no emergency power supply mode is
possible. The messages must also always be parametrised in OPERATING CURRENT.
Function Flag Function Flag Function Flag Function Flag
Mains <U 3A01 Gen. <U 3A10 Mains <U or >U 3A03 Gen. <U or >U 3A30

Sprinkler operation
The following functions are intended for the operation of an electrical sprinkler pump:
Switching of all switching-off alarms (overspeed alarm remains switched off for electronic speed sensor,
demand VDS 2100-22) to warning
Optionally, the inhibition of the generator switching-off function for GENERATOR OVERCURRENT, for
example
Start program to 6 (parametrisable) start attempts
For ending the sprinkler requirement: Cessation of the sprinkler operation after the SPRINKLER IDLE TIME,
or only manual switching off
For the duration of the acceleration time of the sprinkler pump: Switching off the emergency power con-
sumers or no interruption of the emergency power supply.
The time stage for the sprinkler operation idle time can be set in the range of 20 to 2500 seconds. If it is
parametrised to 0 sec., the genset does not automatically switch off (demand VDS 2100-22). In this case, the
LED of the OFF operating mode flashes. The genset can then only be stopped via the OFF operating mode (or
always via QUICK STOP).
The interruption of the emergency current operation for the switching on of the sprinkler pump can be para-
metrised in the range of 0 to 25 sec. For the 0 sec. setting, there is no switching-off of the consumers. The
switching-off of the consumers begins with the SPRINKLER OPERATION signal.
If the sprinkler requirement is met, the emergency power consumers are also switched on during a power
failure or remote start. For return of the power or after removal of the remote start command, the emergency
power consumers are switched back to the mains after the switch-back delay.

Further relay functions
In order to control further functions of the switchgear (lamp test, manual operation or similar) diverse func-
tions are parametrisable to relay. The list of functions with the respective flags is listed further down. Fur-
thermore, non-listed functions of the relay can also be controlled. The possibility and the respective parame-
ter must be queried in the KUHSE SERVICE DEPARTMENT.
Example: A relay can be parametrised in such a way that it (for an intended manual level in the switchgear)
applies in the MANUAL and TEST operating mode.
The K15 to K17 (closer) relays switch the common potential of terminal 15. They can be used for issuing the
switch-on pulse for the mains and generator circuit breaker, indication of operational conditions, alarms, etc.
