VOLTAGE FAILURE
If the alarm VOLTAGE FAILURE appears, then the unit is equipped with a
voltage monitor, which prevents operation in the event of over-voltage, under-
voltage, phase loss, or phase-sequence reversal. (See following pages.)
In this case, a person qualified to work with exposed line-voltage electric terminals
should determine which failure condition is present, and correct as necessary.
Continuous operation with voltages greater than 110% of nameplate voltage or less
than 90% of nameplate voltage may damage motorized equipment. Where this is the
case, consult an electrician for corrective measures.
Operation with a missing phase may damage motorized three-phase equipment.
Correct any missing phase.
Phase-sequence reversal will cause three-phase motors to turn backward.
If the supply blower fails to run, check the controller interface.
