24: Lockout Active – The drive is in a lockout condition and cannot be started.
24: Main Contactor - The drive’s main contactor is energized, bypassing the pre-charge
resistors.
25:
Output Contactor Control – When there is an output contactor for each inverter in a
parallel inverter drive, each inverter should have a digital output programmed to control
its output contactor.
26:
Shunt Trip Non Fail Safe – Relay 2 on the Computer Card must always be incorpo-
rated in the logic to trip the shunt on the feeding circuit breaker. Additional digital outputs
may be programmed as shunt trip non fail safe outputs and incorporated in the logic. For
a Parallel Inverter Drive, one of the CCI digital outputs shoud be programmed as a shunt
trip output. Non Fail Safe outputs are normally de-energized.
27:
Shunt Trip Fail Safe – Relay 2 on the Computer Card must always be incorporated in
the logic to trip the shunt on the feeding circuit breaker. Additional digital outputs may be
programmed as shunt trip non fail safe outputs and incorporated in the logic. For a
Parallel Inverter Drive, one of the CCI digital outputs shoud be programmed as a shunt
trip output. Fail Safe outputs are normally energized.
