NO LOAD TEST:
To allow a timed No Load Test of the engine/generator set while using the
AMF control application, a digital input contact from an external timer
must be programmed for NO LOAD Test
(Refer to Section 10.5.8
for
programming details).
The sequence of operation for a No Load Test condition is as follows:
•
With the utility supply normal and the generator stopped, a no load
test sequence may be initiated by closing an external exercise timer
contact to the programmed digital input for No Load Test.
•
Once the external exercise timer contact closes, the engine will start
and come-up to normal operating speed and voltage. The MEC will
issue an alarm of a No Load Test condition. The connected transfer
switch will remain on the utility and the generator will not transfer on
load.
Note
: should the utility supply fail, the generator will
automatically transfer on load.
•
The engine will continue to run as long as the external exercise timer
contact remains closed.
•
Once the external exercise timer contact opens, the engine will
continue to run for its cooldown time as programmed, then it will
automatically stop.
