To Next PageTo Next PageWhy ASCO POWER TECHNOLOGIES Switch does not transfer the load to emergency source after the gen-set starts?
The ASCO POWER TECHNOLOGIES Switch may not transfer the load to the emergency source if the generator output circuit breaker is not closed or if the generator frequency is below 57 Hz. Allow the Transfer to Emergency Delay (0 to 5 min.) to expire. If you need an immediate transfer, press the BYPASS TIME DELAY button.
Why ASCO POWER TECHNOLOGIES Switch gen-set does not start when the TRANSFER SWITCH TEST button is pressed?
If the ASCO POWER TECHNOLOGIES Switch gen-set does not start, hold the TRANSFER SWITCH TEST button for 15 seconds, or ensure the outage lasts long enough to account for the 1 or 3 second Momentary Normal Source Outage Delay, plus engine cranking and starting time.
What to do if ASCO POWER TECHNOLOGIES Switch gen-set does not stop after load retransfer to the normal source?
If the ASCO POWER TECHNOLOGIES Switch gen-set doesn't stop after load retransfer, allow the 5-minute Unloaded Running Delay to time out.
What to do if ASCO POWER TECHNOLOGIES Switch does not transfer the load to normal source when normal returns?
If the ASCO POWER TECHNOLOGIES Switch doesn't transfer the load to the normal source, wait for the Retransfer to Normal Delay (1 second to 30 minutes) to time out. For immediate re-transfer, press the BYPASS TIME DELAY button.
