I have an Intellitec Model 700 EMS. Yesterday the rear air conditioner stopped working. Discovered no AC power to unit. All lights on EMS panel lit. Green light on EMS control board lit. Only discrepancy I can find is that power from 20 amp breaker TO EMS relay is present, but only 2 volts FROM relay to unit. I shut off AC and DC power for 10 minutes. Upon re-energizing, EMS display lit up in 1 sec. intervals as usual and audible click heard on all relays. Still no power to air conditioner. (30 amp or GENSET power applied.) Took hot wire from output side of EMS relay and attached it to 20 amp breaker. Air conditioner works! I suspect the relay or entire control need replaced.
1. Will continued operation with one EMS relay bypassed cause any lasting damage to rest of control board? (We can self-regulate power usage.)
2. Are individual Intellitec relays replaceable?
3. Any other thoughts?
It's Saturday (Intellitec closed) and 104 in Indianapolis!
