The “Remote start” option allows to switch the unit on or off with-
out using the control panel located on the unit. The start module of
the control panel is replaced by a special module which provides
extra connections for the remote start/stop switch and the plant con-
tactor (voltage free contact), both to be installed by the customer.
The different positions of the starter switch ST are:
– : used to select normal start and to disable remote start.
– O : used to switch off the power supply from the battery. The unit
will not be able to start up.
– : used to select remote start.
To start up the unit locally, without using the remote
start/stop switch, proceed as follows:
– Switch off circuit breaker Q1. This is not necessary when a plant
contactor is installed between Q1 and the load.
– Put the starter switch in position . The unit starts a preheating cy-
cle which takes 12 seconds.
– After the preheating period, the unit will start. The starting attempt
will take maximum 12 seconds.
– Approximately 15 seconds after starting (stabilisation time for the
generator), the timer relay closes the voltage free contact and the
plant contactor is energized (if installed).
– Switch on circuit breaker Q1 in case no contactor is installed.
To stop the unit when the starter switch is in position ,
proceed as follows:
– Switch off the load.
– Switch off circuit breaker Q1.
– Let the engine run for about 5 minutes.
– Stop the engine by putting the starter switch in position O.
– Lock the side doors and the door of the indicators and control panel
to avoid unauthorized access.
To start up the unit from a remote location using the re-
mote start/stop switch, proceed as follows:
– Put the starter switch in position .
– Switch on circuit breaker Q1.
– Put the remote start/stop switch in position start. The unit starts a
preheating cycle which takes 12 seconds.
– After the preheating period, the unit will start. The starting attempt
will take maximum 12 seconds.
– Approximately 15 seconds after starting (stabilisation time for the
generator), the timer relay closes the voltage free contact and the
plant contactor is energized (if installed).
To stop the unit when the starter switch is in position ,
proceed as follows:
– Switch off the load.
– Let the engine run for about 5 minutes.
– Stop the engine by putting the remote start/stop switch in position
stop or by putting the starter switch in position O.
The plant contactor should be sized according to the
load. The maximum current through the voltage
free contact is 3 A.
The remote start/stop switch Sx has to meet the fol-
lowing specifications: 12 V DC, 4 A.
Refer to the circuit diagram for the correct connec-
tion of the plant contactor and the remote start/stop
switch.
The minimum voltage relay on the main circuit
breaker of the standard unit is eliminated and
replaced by a current coil which switches off Q1 in
case of an emergency stop or an earth fault.
