10.6 Rotation direction indicator - Phase controller
Description
The phase controller enables permanent and easier verification of the rotation direction of the
machine by means of a diode. This prevents any risk of physical damage by disabling the
compressor start up in case of phase reversal or if a phase is disconnected and indicates a
machine fault.
Marking on the motor of the standard machine version identifies the motor fan rotation direction
during the start up phase. Work on the electric network or the machine may change the rotation
direction and damage the compressor which must be detected quickly.
10.7 Remote starting and stopping
Description
This option allows the compressor to be remotely started and stopped. However, in all cases,
stopping the compressor at the machine itself is essential. If the compressor is shut down from
remote it may be restarted from remote as well.
Technical features
This option requires configuration of the electronic controller and installation of an informative
insert on the door of the compressor electric cabinet.
Whenever the compressor is shut down, the emergency push-button must be pressed or the
electricity isolating switch opened.
For any intervention to be conducted on the machine, it is essential to activate the
emergency stop of the machine in order to ensure safe conditions and electrical diagram.
