How do I perform a transfer test?
To perform a transfer test, flip the momentary switch to the transfer test position and hold it for 15
seconds or until the switch actually transfers over.
How does the ATS work?
When referring to an open transition transfer switch, the transfer switch main contacts moves in a quick
break - before make mode transition. There is no momentary parallel connection of the two sources and
no extended center-off position during transfer. The transition is quick. The ATS controller monitors the
voltage and frequency of the two sources (upon re-transfer or any transfer between 2 “live” sources) and
ensures that they are in-phase before the load is transferred (if enabled).
How does the engine exerciser work?
The engine exerciser works by closing the engine start contacts and keeping it closed in order to crank and
run the generator. The engine start contacts are kept closed until the exerciser operation timer expires
(approximately 20 minutes). Controller signals the engine start contacts to open up and shut the generator
down completely (after the 5 minute engine cool down period).
