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.
10.8 Special oils
Description
Different oils meet different needs:
4000 hours oil : longer interval between 2 drainage operations - 4000 hours under standard conditions of
use.
8000 hours oil : longer interval between 2 drainage operations - 8000 hours under standard conditions of
use.
Food Grade Oil: use of the compressor in the agricultural food & beverage industry.
Note:
If this option is chosen on a machine that has previously run on standard oil, the flushing procedure must
first be strictly complied with.
The indicated oil exchange intervals are valid for standard operating conditions (see section Reference
conditions and limitations ) and nominal operating pressure (see section Compressor data ). Exposure of the
