How will I know if the controller is non-operational?
1. The indicator lights are not showing proper indications.
2. The switch transfers even if there is no loss of utility power and no transfer test operation or exercise with transfer
is confirmed.
3. The relays are not operating according to the normal sequence (no voltage from the board socket to supply the
relay coils).
4. The engine exerciser has malfunctioned even if the battery is new, or exercises at a random schedule, or does
not function.
5. The generator would not start even when a start signal is verified or does not shut down.
6. The command buttons, DIP switches or potentiometers are non operational.
7. Discoloration or indication of damaged components visible on the circuit board.
8. Remote control switches are not functioning even though proper values have been set.
9. No power present at inputs from the harness.
Consult technical support group to verify the conditions
What should I do if the indicator lights are not functioning properly?
1. Check to determine if correct voltage is applied across the main contacts. This requires opening the enclosure
door and wearing the appropriate PPE.
2. Check that voltage sensing wires have continuity.
3. If the voltage across the terminals is acceptable, but the lights are not operational, then the controller should be
replaced.
Note: Checking these items requires an ASCO Services technician or a licensed electrician!

Why won’t the engine exerciser light blink after setting (press and hold the button)
the exerciser?
1. Check engine start contacts to confirm they change position. If it doesn’t, controller may be non-conforming,
replace controller
2. If start contacts change position, generator may have a problem. Contact local generator distributor.
3.
Check the 9-volt battery and the S2 dipswitch setting of the battery. It should be ON.

Why doesn’t the engine exerciser light blink to indicate the remaining number of
days until the next exercise period?
1. After the exercise period stops, the flashing light will remain on to indicate that the exercise is enabled and another
exercise will be conducted after a week.
