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.

Manual Controls

These controls are located on a panel behind the Control Panel door. They are provided to assist in

initial system start-up and provide emergency manual breaker trip capability. During normal opera-

tions they should not need to be used.

Close Load 1

This button closes the Load 1 circuit breaker during start-up. It only functions if the Tie breaker is

open.

Close Load 2

This button closes the Load 2 circuit breaker during start-up. It only functions if the Tie breaker is

open.

Trip Load 1

This button is used to manually trip the Load 1 circuit breaker and is provided for emergency pur-

poses.
The light on this push button will go out when load is being supplied through the breaker. Pressing

this button when the light is out will result in loss of power to an on-line load.

Trip Load 2

This button is used to manually trip the Load 2 circuit breaker and is provided for emergency pur-

poses.
The light on this push button will go out when load is being supplied through the breaker. Pressing

this button when the light is out will result in loss of power to an on-line load.

Trip Tie

This button is used to manually trip the Tie circuit breaker and is provided for emergency purposes.
