Function
The Main screen menu shows in short the compressor operation status and is the gateway to all functions
implemented in the regulator.
Procedure
The Main screen is shown automatically when the voltage is switched on.
If the function keys or arrow keys (1, 2 and 3) are not used for about 4 minutes, the regulator will
automatically return to the Main screen.
Exception is made when the screen is left untouched when modifying data in the regulator. In this case, the
screen will remain unchanged, since the regulator does not take a decision whether to accept or refuse the
new data.
The display indicates:
• The name of the sensor of which the actual reading is displayed
• The unit and actual reading of the sensor
• Messages regarding the compressor operating condition (e.g. “Automatically Loaded”), a service
need or a fault (motor overload, shut-down, warning, sensor error)
• Just above the three function keys (F1/F2/F3), the actual functions of these keys
When more than one message needs to be displayed (e.g. both warning and service), the
messages will be displayed one after the other for 3 seconds.
