OPERATION
The control panel commands are enabled.
Starting with key
stopping with key .
CONTROL FOR MAINS-GENERATOR CONTACTORS
It is left to the key
.
By pressing on the key, the load is switched from the mains to the generator and vice versa.
PROTECTIONS
The generator set protection function in manual mode can be programmed in two ways:
· Display only of the fault that has intervened WITHOUT STOPPING the engine. The generator overfrequency fault is
programmed with stopping of the engine. It cannot be programmed without stopping of the engine.
· Display of the fault that has intervened WITH ENGINE STOPPING. (The control panel is programmed in
this way).
When a fault occurs on the mains, (detected by the internal oltmetric relay, or by the external call), once
the 2 seconds have elapsed, the control unit commands the opening of the mains contactor control, and
starts the generator set. With engine running and generator voltage normal and once the GENERATOR TO
POWER USERS CONNECTION DELAY has elapsed (programmed to 7 sec.) the generator contactor closes.
While it is running the generator set is protected from possible faults. When the mains voltage is restored
and the MAINS ACCEPTANCE time has elapsed (programmed to 40 sec.), the mains contactor closes (after
the GENERATOR-MAINS INTERLOCK time, programmed to 1,5 sec. not adjustable).
The COOLING TIME (programmed to 120 sec.) then allows the engine to be cooled easily before it is stop -
ped.
Press button until the warning led comes on.
The engine cannot be started in any way and, if running the engine is stopped without carrying out engi -
ne cooling. The mains contactor stays closed. The LEDs and the instruments are active.
On pressing key up the lighting , we obtain the engine startup cycle as in automatic,
and the power users remain supplied by the mains. If a mains fault occurs during the test, the power unit
remains in test mode, positions itself as in automatic operation and commands the closing of the genera -
tor contactor.
ENABLED WITH POWER UNIT IN AUTOMATIC OR TEST MODE is indicated by the display .
If the relative switch is positioned on TEST ENGAGED the general alarm is activated intermittently (for 8
sec.). When the general alarm is deactivated, and after a pause of 3 seconds, the engine starts and conti -
nues to run for 3 minutes.
This test will be repeated automatically every week on the exact day and at the hour to which the
TEST ENGAGED switch has been positioned.
STOPPING OF ENGINE DURING THE TEST
Press button and move to function .
UPDATING OF THE HOUR LEAVING THE SWITCH ON TEST ENGAGED
Keep pressed at the same time keys and until the icon TEST starts to flash.
Press key within 3 sec..
The weekly test cycle is therefore obtained as if the relative switch had been repositioned.
