Compressor operating mode may be set AUTOMATIC or CONTINUOUS:
AUTOMATIC: this is the setting used in most cases (factory setting). In this operating mode, idling is
timed; at the end of the count, the compressor stops, preparing for subsequent automatic start-up (see
also paragraph 7.3 STARTING the compressor). This promotes energy saving if there is no or a very
low request for compressed air.
CONTINUOUS:this setting should be used in very particular applications characterized by a considerable
variation in compressed air consumption combined with a reduced plant accumulation capacity. With
this setting, the compressor starts unload run without ever stopping the motor and is therefore able to
supply air continuously in the case of a request from the network. The system configured in this way
is highly reactive. However, one of the drawbacks of this operating mode is that it entails higher power
consumption due to the fact that the compressor is always running (see also paragraph 7.3 STARTING
the compressor).

control options.
If the compressor is equipped with a CAN-BUS interface, the network-continuous / network-program
control options are also visible and can be selected.
Compressor control can be set to:
LOCAL: this is the basic (factory) setting that permits control from the keyboard
REMOTE: with this setting, the compressor can be controlled by means of an external remote switch.
For the electrical connections, refer to the following submenu (refer to the following paragraph "Type of
remote control")
PROGRAM: enables the daily or weekly programming set and enabled in the PROGRAMMING menu
(see paragraph 7.4.2.6)
NET-CONTINUOUS: this is the setting for control of a sequence of compressors, without daily/weekly
program
NET-PROGRAM: this is the setting for control of a sequence of compressors according to the daily/weekly
program set
Dryer control
This menu is used to activate/de-activate the dryer
Type of remote control
For remote control, modifications must be made to the wiring of the compressor as described in
paragraph 6.5.
When compressor control is set to REMOTE (see previous submenu), three types of control methods
are possible:
ON/OFF is the setting that makes it possible to control switching ON/OFF of the compressor. This is
the factory setting (that most frequently used) which makes it possible to exploit the control logic of the
compressor using the pressure signal measured locally by the machine
