After validation of the test, the
orange LED
on the test keypad lights up steady.
During the start-up phase, and until the alternator voltage and generating set speed
stabilise, the
green LED
underneath the symbol for the generating set flashes and
becomes steady at the end of this phase.
The installation is then controlled via the programmable controller in accordance with the configuration of the application:
normal/emergency source switchover
grid
coupling
etc.
The Normal/Emergency switchover with grid coupling is only possible by carrying out a load test.
The purpose of the off load test is to start a single GS or to couple a power plant (x generating sets) to the
emergency busbar.
Important
At any time the generating set may be stopped by pressing
Stop
or by pressing
0
on the
test keypad.
Pressing
Stop
may interrupt the power supply, depending on its status when the key is pressed (e.g.
isolated grid operation).
The generating set will stop after a cooling delay (180 seconds by default).
Important
The
green LED
underneath the generating set symbol goes out to indicate that the
generating set has stopped.
