The control panel has three operating buttons and the hour counter to memorize the number of machine
operating hours (Fig. 43-44).
1 ON
- green button.
It enables the compressor to be started up.
The button has a light inside that comes on
when it is pressed.
(The general switch must be in the “ON”
position).
2 OFF
- red button.
It enables the compressor to be stopped.
The button has a light inside that comes on
when the power supply is connected.
3 MANUAL PURGE
- yellow button.
It enables the condensate to be purged
manually.
This function permits the pressure present
inside the condensate separators and the
filter to be discharged, evacuating the con-
densate through the electromagnetically-
controlled valves.
This operation is normally carried out by the
timer at regular intervals.
4 HOUR COUNTER
It enables the actual operating hours to be
memorized in order to be able to carry out
the maintenance work as provided for.
