Liebert Series 610 user manual Manual Controls

Control Panel Description

Voltage Lockout

This light indicates the system voltages are too far apart to allow safe transfers and parallel operation of the UPS systems. To correct this condition, adjust the UPS system voltage to proper levels.

If both system voltages are adjusted correctly, and the PHASE LOCKOUT alarm is not present, then check the voltage detection circuitry. Contact Liebert Global Services for assistance.

Load Lockout

This light indicates insufficient UPS capacity to perform the selected operation. The control logic intelligently checks the UPS systems and the Loads based on the specific operation in progress.

Verify UPS capacity and shed load as necessary until UPS capacity is not being exceeded. If UPS capacity is sufficient, then check the load/capacity detection circuitry. Contact Liebert Global Services for assistance.

Logic Failure

This light indicates that a logic failure has occurred. No Tie operations are allowed while this condi- tion exists.

Check all tie control logic functions to determine the source of the fault. Contact Liebert Global Ser- vices for assistance.
