Remote Stop
When the remote start-up/stop function is activated (P07), the compressor will execute a controlled stop, as if the interface stop
button was pressed, when the remote start-up/stop input is in open circuit.
Remote Start-up
When the remote start-up/stop function is activated (P07), the compressor will execute a normal start-up sequence when the
remote start-up/stop input switches from open to shorted circuit. If it's shorted, the start-up/stop input must be opened and
shorted again to start a remote start-up sequence. The local start-up of the control will be disabled.
Enable remote load:
When the digital input to enable remote load is active, the local or the pressure communication settings will be neglected and the
compressor will respond to the digital input for remote load. The compressor will automatically respond to the pressure setting
method defined in the configurations (local or by communication), when the digital input to enable remote load is not activated.
Remote Load
When the digital input to enable remote load is active, the compressor will load when the digital input to enable remote load is
activated and unload when the remote load input is deactivated. All the pressure safety settings remain active when the remote
load functions are used.
Note: If the line pressure is higher than the one set for the alarm level, the release solenoid will be powered off. The solenoid will
remain unpowered for 10 seconds after the pressured drops below the alarm level.
