2.6. Starting the compressor
The compressor can be started according to the following procedures depending on the status of the
compressor.

The “OFF” message on the controller display indicates that the compressor is properly powered, waiting to be
started, and that the last switch-off was caused by pressing the “OFF” push button on the controller (local switch-
off).
To start the compressor, use local controls, that is, press the “ON” button on the control unit.
Note! In this condition, opening and closing the remote contact will not produce any effect whatsoever.
Starting the compressor in “---” status
The “---” message on the controller display indicates that the compressor is properly powered, waiting to be
started, and that the remote START/STOP contact is in the OPEN position (STOP position).
To start the compressor, use the relevant procedure described below, depending on how the last switch-off
occurred.
• If the compressor was running (no matter whether loaded, unloaded or in stand-by) and was then switched
off remotely, that is, by opening the relevant contact, then the “---” message appears. To restart the
compressor, close back the remote contact.
• If the compressor was switched off locally, that is, by pressing the OFF button on the controller, and the
remote contact was opened AFTER the switch-off, the “---” message appears.
1. To restart the compressor, close the remote contact.
2. Press the ON button on the controller.
