Step 1. Check for a start signal from the transfer switch
| ATS MODEL | COMMAND | PASS | FAIL |
|---|---|---|---|
| WINCO | Check continuity between Start and Bat – on switch | Continuity. The generator should be running | No continuity: Go to Step 2 |
| ASCO165 ASCO185 | Closed on Start = Continuity between terminal block 7 terminals 4 and 5 | Continuity: The generator should be running unless we are sure the time delays for cool down have expired. If the contact does not open after time delays replace transfer switch controller | No continuity: Go to Step 2. 185 Switches – check QV battery |
Step 2. Check if generator is in a cool down delay.
| ATS MODEL | COMMAND | PASS | FAIL |
|---|---|---|---|
| WINCO ASCO165 ASCO185 | Go to generator controller > Check to see if it is in a cool down delay. If so, wait for it to expire. Beware of stacked time delays | Generator in a time delay: Should be running. Go to Step 3 | Generator not in time delay but running: Troubleshoot generator or ATS board for improper shutdown |
Step 3. Adjust Time Delays to Prevent Nuisance Calls
| ATS MODEL | COMMAND |
|---|---|
| WINCO | Not applicable |
| ASCO165 | Fixed time delays. Can only adjust generator delays. Adjust the generator controller time delay to reduce stacked delays. Generator delay won’t start until transfer switch removes start signal |
| ASCO185 | Select the proper generator cool down and adjust Switch 1 Actuator 10 On (Up) 2 Minute Off (Down) 5 Minutes Adjust the generator controller time delay to reduce stacked delays. Generator delay won’t start until transfer switch removes start signal |
