	or open contactor.
CONTACTOR CLOSE FAIL	Contactor failed to close on startup.	X

FAN OPEN	Fan open circuit or disconnected.	X

FAN SHORT	Fan short circuit.	X

PUMP OPEN	Pump open circuit or disconnected.	X

PUMP SHORT	Pump short circuit.	X

HW OVERSPEED	Hardware detected overspeed.	X

PRECHARGE PROTECTION	Stop PWM when large voltage differential exists	X
	between internal and external bus.
BUS CURRENT OFFSET	DC current sensor error.	X

S - Indicates a Certified Service Provider will be required to reset system.

NOTE

If a fault recurs after being cleared by the operator, and the condition persists, contact your Liebert technician.

Faults that initiate an AUTOSHUTDOWN include: MISER, RUNOUT, PWR SPLY VOLT (at high speed), and will require Service level and higher to reset.
