No 3-Phase Power

No 3-phase power fault occurs if a run command has been sent

from the control module to the contactor (or pilot relay) and voltage

isn’t present at the motor terminals. This will not result in a lockout

condition; If demand remains, the compressor will continue to

attempt to run until voltage at the motor is present. This fault will

typically occur during start-up.
