3.5 During operation (Fig. 3a)
1. When automatic operation LED (1) is alight, starting and
stopping of the motor is controlled automatically.
2. Check the readings on display (4). See below.
3. On reaching the pre-set unloading pressure, shown on
display (4), the compressor will run unloaded. The
operation of the compressor is automatically controlled
by the regulator depending on the air consumption.
4. To unload the compressor manually, press key
<<Unload>> (5) 1). To put the compressor back into
automatic operation, press key <<Load>> (5) 1).
Important
- If the compressor is stopped, it may start automatically.
See also section 1.2.1.
- The regulator will only react to a new control mode if the
new position of key (S5) is maintained for 3 seconds.
- To avoid unauthorized switching over to another control
mode, take out key (S5) after selecting the required mode.
See also section 1.2.3.
3.5.1 Checking the display (4-Fig. 3a)
1. Regularly check the display for readings and messages.
Normally, the main display (Fig. 3b) is shown, indicating
the compressor outlet pressure, the status of the compressor
and the functions of the keys below the display.
2. Always check the display and remedy the trouble if alarm
LED (3) is alight or blinks. See section 1.2. Also consult
the "User manual for Elektronikon regulator", section
"Submenu STATUS DATA".
3. The display will show a service message if one of the
monitored components is to be serviced; replace the
component, change the oil or grease the drive motor as
the case may be. Reset the relevant timer. Consult the
"User manual for Elektronikon
®
regulator", "Submenu
SERVICE".

According to the table, the minimum allowable temperature at the outlet of the compressor elements is 68°C.
Regulate the cooling water flow during loading to obtain a temperature between 70°C and approx. 75°C at the outlet of the
compressor elements
