ENABLED WITH CONTROL UNIT IN AUTOMATIC MODE (For programming see page 10)
after a pause of 3 seconds, the engine starts and continues to run for the WEEKLY TEST TIME (programmed to 3
minutes).
This test will be repeated automatically every week on the exact day and at the hour to which it has been
programmed. During the automatic test cycle, WEEKLY AUTOMATIC TEST is shown on the display.

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 faults overfrequency,
overspeed and emergency of the generator are 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 unit is programmed in this way).

WEEKLY AUTOMATIC TEST
When a fault occurs on the mains, (detected by the internal voltmetric relay, or by the external call), once the
ime have elapsed, the control unit commands the opening of the mains
contactor, and starts the generator set.
With engine running and generator voltage normal and once the GENERATOR TO POWER USERS
CONNECTION DELAY has elapsed, 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, the control unit commands
the opening of the generator contactor, after the GENERATOR-MAINS INTERLOCK time the mains contactor
closes
The COOLING TIME allows and facilitates subsequent cooling of the engine before stopping it.

On pressing key , 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 control unit remains in test mode, positions itself
as in automatic operation and commands the closing of the generator contactor.
