3. The display (3) will show a service message if a service
plan interval has been exceeded or if a service level for a
monitored component has been exceeded. Carry out the
service actions of the indicated plans or replace the
component and reset the relevant timer.
Warning Before carrying out any maintenance, repair or
adjustment, stop the compressor, press emergency
stop button (S3-Fig. 3.4), switch off the voltage
and depressurize the compressor.
Notes
- Whenever a warning, service request, sensor error or motor
overload message is displayed, the free spaces on the display
between function keys (9-Fig. 3.4) are filled with blinking
indicators (**).
- 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.
3.6.4 Manual control (Fig. 3.5)
Normally, the compressor runs in automatic operation, i.e. the
electronic regulator loads, unloads, stops and restarts the
compressor automatically. LED (8) is then alight.
Manually unloading
Press key "Unld" (F3). LED (8) goes out. The message
"Manual Unload" appears on the display. The compressor
remains running unloaded unless it is loaded again manually.
Manually loading
Press the key "Load" (F3). LED (8) lights up. The command
will switch the compressor to automatic operation again: the
compressor will be loaded if the air net pressure drops below
the programmed level.
Manually starting
In automatic operation, the regulator limits the number of motor
starts. If the compressor is stopped manually, it must not be
restarted manually within 5 minutes after the last stop.
Note
If the "Load" or "Unld" (unload) function is not indicated on
the bottom line of display (3), press key "Menu" (9) until the
function "Main" appears above key (F1), then press the key
"Main".
3.6.5 Stopping (Fig. 3.5)
1. Press stop button (1). LED (8) goes out. The message
