NOTE
The connection of the compressor module
(STD) shown in these operating instructions is
suitable for most compressor control systems.
These operating instructions can only describe
the function of the compressor module (STD),
but not the detailed installation in any possible
compressor model (third party manufacturers).
Installation and functional implementation must
be done in accordance with the associated com-
pressor documentation and possibly in consulta-
tion with the compressor manufacturer.
Digital Inputs
NOTICE
Property damage
If a compressor module (STD) is installed, the
pressure switch on the compressor may no
longer provide any protective against overpres-
sure.
➯
For compressors that are not equipped with
an independent overpressure detection
system, it is recommended that a pressure
switch be integrated in the fault circuit of the
compressor, so that any local overpressure
situation will stop the compressor indepen-
dently of the GD PILOT TS master.
The module detects the compressor status via
three digital inputs, the status of which is shown by
three LEDs on the module. A voltage of 24 to 230
V AC or DC may be connected to each input.
There are three connections available for each in-
put:
24..48 V UC connection
110..230 V UC connection
COM connection
The signal voltage used must be fed to the appro-
priate connection.
"Operating" digital input
A signal must be connected to this input that in-
dicates that the compressor is ready to produce
compressed air if a remote On-Load signal is sent.
For compressor controllers that do not have such
a signal, the input can be connected to a common
fault signal for the compressor.
This informs the GD PILOT TS master, that there
is no fault at the compressor.
"Motor" digital input
Contacts A1 and A2 of a main contactor coil can
be connected directly to this input.
If the compressor controller energizes the coil of
the main contactor, the compressor module de-
tects the voltage across the coil and informs the
master that the motor is running.
For compressor controllers that have no main con-
tactor, any output can be used that indicates that
the motor is running, e.g., a fan contactor or soft-
start signal.
"On-Load" digital input
The control valve coil can be connected directly to
this input.
If the compressor controller energizes the coil of
the control valve, the compressor module detects
the voltage across the coil and informs the master
that the compressor is On-Load.
Any output that indicates that the compressor is
On-Load can also be used.

The compressor is controlled by two or three dig-
ital outputs. The status of these outputs is indi-
cated by three LEDs.
These digital outputs are two-way contacts and
can be adjusted to the requirements of the com-
pressor controller, in that the appropriate terminals
are selected.
"Enable Remote On-Load" digital output
Do not use this output to switch the compressor on
and off.
This output should cause a changeover from inter-
nal controls to control by means of the digital out-
puts of the compressor module.
