25 TEST
Color: gray
Operating mode TEST
By actuating the "TEST" push-button, the engine is started, and engine monitoring is
activated. No power circuit breakers are operated. This is carried out in the event
of mains failure and when emergency power is switched on.
Start of a load test
A load test is enabled via the actuation of the "GCB ON"
push-button. In addition to the functions of "TEST" mode, the GCB is
synchronized or the MCB is opened according to the CB logic and
the GCB is then switched to the black busbar. The power can be
changed by actuating the setpoint value push-buttons.
End of a load test
The "LOAD TEST" can be terminated by actuating the "GCB
OPEN" or "MCB ON" push-button (depending on power circuit
breaker logic). In "STOP" or "AUTOMATIC" mode without request
signal, the genset is stopped with a reduction of power.

(STOP)
Color: red
Operating mode STOP
By selecting the "STOP" mode, the genset is always shut down. The shutdown pro-
cedure is as follows:
Stopping process:
•
the "STOP" mode is selected,
•
the real power is reduced,
•
the GCB is opened at 5 % of the rated generator real power,
•
coasting is carried out according to the parameters in order to cool the engine.
If the discrete input at terminal 64 is configured as control input using the parameter "Op.mode blocked by
Ter.63" and energized, it is possible for units with Package P01 from version 4.3010 to select the operation
mode externally using the control inputs at terminals 127 and 128. The functionality is described in the follow-
ing table:
