PLEASE READ THE FOLLOWING SAFETY INSTRUCTIONS...
Follow the below steps to test the function of the F50-ATS.
BEFORE TESTING
:
Ensure air conditioning units and other high current users are switched off. It is
harmful for the transfer switch to switch over power sources while under load.
Shut down all power sources to the RV
Label power sources clearly that testing is in progress.
If accessible, remove the lid of the ATS to visually check function.
ATS FUNCTION TESTING:
1. Plug in the shore power cable and turn on the dockside shore power breaker, as soon
as the shore side breaker is turned on you will hear a clunk noise immediately as the
shore power contactor engages inside the ATS, power is then supplied to the RV from
the ATS line out feed.
2. Turn off the shore side power breaker to shut down power to the RV, you will hear a
clunk as the Shore power contactor disconnects (keep the shore power cord connected
with no power for further testing).
3.Start the Generator in the RV and wait for it to run up to speed, as soon as power is fed
to the ATS from the generator the green LED indicator light on the internal ATS PCB will
illuminate, the ATS has a 20-30 second time delay before engaging the internal contactor
to allow for the generator to warm up. After 20-30 seconds you will hear a clunk noise as
the generator contactor engages inside the ATS, power from the generator is now supplied
to the RV from the ATS line out feed.
4. Shut down the generator
ATS SWITCHING TESTING:
To test the switching function after both function tests have passed:
1. Turn on the shore cord shore side breaker to engage the shower power contactor, power
is now being supplied to the RV by the shore power.
2.Start the generator and wait for it to warm up, after 20-30 seconds you will hear a clunk as
the unit automatically switches over power sources from shore power to generator.
3.Turn off shore power from the shore side breaker and confirm the generator is feeding the
line out, the power supply should not be interrupted by doing this.
4.Turn on the shore power shore side breaker again which will engage the shore power
contactor. While the shore power is still connected and on, then turn off the generator, this
will then disengage the generator contactor and automatically switch to running on shore
power feed.
