C. POWER CUT-OFF INTERLOCK INDICATOR DIAGNOSTICS

The purpose of an interlock system is to interfere with the operation of the lift if an unsafe condition is

present. When interlock systems are added to the lift, the light is an indication whether or not the interlock

is operating properly. The light is placed within the electrical system so that no matter which interlock

system/method is used, the light will be ON when the interlock allows operation of the lift and OFF when

the interlock has disabled the lift. When there is no interlock system installed, the light stays illuminated.

On all lift assemblies without the optional door operator, there is a light-assembly installed in the position

where the door operator circuit breaker would normally be mounted. The light indicates when power is

being supplied to the signal portion of the electrical system. The light will aid in diagnosing electrical

problems. Refer to Table [4-4]:

TABLE [4-4]: INTERLOCK INDICATOR TROUBLESHOOTING GUIDE

SYMPTOM POSSIBLE CAUSE

Light is not lit, lift does not

operate.

Control system circuit breaker is tripped.

Light is not lit, lift operates. Light needs to be replaced.

Light is lit, lift does not operate. If there is a problem with the lift electrical system, check the

power and/or the signal circuitry. Both may have to be

checked, but check the power circuitry first.
