lock the room containing the compressor and
instruct your staff.
Fit the main switch specified by EN60204 and fit
the appropriate warning signs on it.

12.4 Remote Start / Stop
12.4.1 Description
Danger
In this operating mode, the compressor may start
up automatically at any time.
Caution
Only potential-free contacts may be connected
to the terminal strip. External voltages will
destroy the GD Pilot TS.
The potential-free contacts must not be more
than 20 metres away from the terminal strip. If
necessary, coupling relays must be fitted in the
control cabinet.
The remote start / stop function allows the operator to
start and stop the compressor from a remote location.
This function is permanently programmed and has its
own dedicated terminals (see circuit diagram supplied
with your compressor).
The unit continues to run while the potential-free
contact is closed. If the contact is opened, the soft-stop
is undertaken and the unit stops.
