The controller can also perform an automatic restart
after any power loss period.
For this to be done, you must have read the following
safety notices and authorise the unlimited automatic
restart by entering an authorisation code.
Please request the required code from Gardner Denver
Technical Support.
Danger
In this operating mode, the compressor may
start automatically at any time and for an
unlimited duration after a power loss.
Check the safety regulations that apply in your
country (e. g. EN1012-1, EN60204) to ascertain
whether you are allowed to perform an
unlimited automatic restart and establish which
safety precautions must be taken.
Always fit the compressor with warning signs,
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.
To authorise the unlimited automatic restart, proceed as
follows:
1) Enter the code on the “Access Code” tab.

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.
