Remote start function after a power failure
After a power failure the remote switch must be
switched OFF and then ON again so that the com-
pressor starts.
If an automatic restart is desired after a power fail-
ure, this function must be activated accordingly
(see chapter "Setting automatic restart after a
power failure") and the remote switch must still be
set to "ON" when the power supply comes back on
line.
5.5.8 Remote Load and Off-Load (FS)
This function makes it possible to remotely switch
an FS compressor, e.g. from a control room, off
and on-load.
DANGER
In this operating mode, the compressor
may start up automatically at any time.
➯
Provide the compressor with warn-
ing signs.
➯
Keep the compressor room locked.
➯
Instruct personnel.
➯
Install the main switch according to
EN 60204 and attach a warning sign
to it.
NOTICE
Material damage
➯
Only potential-free contacts may be con-
nected to the terminal strip.
External voltages result in destruction of the
controller.
➯
The potential-free contacts must not be
more than 20 metres away from the termi-
nal strip.
If necessary, coupling relays must be fitted
in the switch cabinet.
Activating the function "Remote Load and

is activated, the on-load/off-load command can
only be given via the remote load input. All internal
pressure setpoints are ignored. If the line pressure
exceeds the set compressor rated pressure due
to a permanent remote load signal by more than
0.5 bar, "Warning A606:Line Pressure high" is dis-
played. As long as warning "A606" is active, the
remote load input is deactivated.
