Air flow monitoring
Air pressure switches monitor the air flow through
the cabinet of the integrated transformer
and the cabinet of the drive
Separate air pressure switches in each cabinet
monitor the air flow through the filter mats and the
air flow through the cabinets.
When the filter mats are clogged and the pressure
drop reaches the specified final pressure loss, the
message Conv1CoolAirFilter is displayed on the
CDP control panel and the alarm/fault lamp lights
up on the control compartment door.
When a fan of the drive or a fan of the integrated
transformer fails, the control system of the drive
switches on the stand-by fan automatically. The
failure of a fan is indicated on the CDP control
panel of the drive as follows:
• CoolCircuit1Alm if a fan of the drive fails
• CoolCircuit2Alm if a fan of the integrated trans-
former fails
The alarm fault lamp starts to flash.
