Simple Test
EMS-GC10 controller unit will go through the start sequence and run the engine for the
time set in parameter 7041 without any breaker operation. This sequence is initiated by
a digital input or the TEST push-button on the front. The test will run until the timer
expires. When the timer runs out, the stop sequence including cooling down will be
carried out.
If the timer in parameter 7040 is set to 0, the test is infinite. The test will be interrupted if
the mode is changed to: manual, semi-auto, or auto.
Full Test
The full test will start the genset, open the mains breaker and close the generator
breaker. When the test timer expires or the test is cancelled by mode change, the
generator breaker is opened, the mains breaker closed, and the generator is stopped
after the cool-down time.
NOTE: To run the full test, it is required that EMS-GC10 is in AMF
or LTO mode.
NOTE: It is possible to open and close the generator breaker and
the mains breaker in manual mode.
