30 User’s Manual GC315xx-GC400xx
INFORMATION! : The operating sequence described above is generic and in some cases may
not correspond to the one implemented in your system. For further information, please contact your
installer/Manufacturer.
The sole purpose of the “TEST” sequence is that of testing the Generator set in order to check the
operating condition in preparation for a possible emergency situation (e.g. a Black out) and to
periodically keep the mechanical parts efficient and lubricated.
The TEST sequence can be scheduled and executed automatically by the Gen-set control module
and periodically with a programming schedule, or manually by means of the operator panel. To
activate the manual sequence, the device must be in the “AUTO” mode. Pressing the “START”
button in this mode activates the Generator set for the “TEST” sequence. The engine stays on,
without switch between the MCB and GCB contactors. It will be up to the operator to end the
“TEST” by pressing “START” again.
WARNING! Pressing the "STOP" button during the test activates an alarm which prevents
the restart of the engine, which can only be reset in the "OFF RESET" mode.
INFORMATION! If a fault occurs on the Mains during the “TEST” phase, causing the automatic
activation of the Generator, the operating mode independently passes from “TEST” to automatic
“AUTO”. When the Mains returns, the mode remains in “AUTO”.
The “TEST” sequence does not foresee the load test with switching from the Mains to the Generator
so as not to cause an unnecessary Black out on the Load. However, it is possible that your system
has been configured to handle the load in “TEST” (parameter P.0222).

not correspond to the one implemented in your system. For further information, please contact your
