Using the KERYS Tactil Man-Machine Interface, the under
load test is started by pressing the corresponding key.
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.
