10 Programmable Inputs and
Outputs
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.
10.1 Programmable Inputs
Fig. 23 Programmable Inputs
A number of programmable inputs are available on the
GD Pilot TS. The number of inputs can vary depending
on how your compressor is set up.
The inputs can be assigned to
monitor conditions or devices when the contacts
on the appropriate terminals are opened, or
to activate functions when the contacts on the
appropriate terminals are closed.
Note
A certain number of programmable inputs may already
be occupied by pre-installed accessories and/or
optional equipment. Refer to the circuit diagram
supplied to check which inputs are freely available.
Caution
If monitoring equipment has been pre-installed and
connected to programmable inputs, you may not
change the corresponding settings, as doing so
would disable the monitoring equipment.
If a programmable input channel is activated, i.e. an
external source has been connected but a function has
not been allocated to this input, the message
Input
“x”
will appear on the screen. This indicates that a
programmable input has been detected (x is the
number of the relevant programmable input) but the
controller does not understand how to process this input
signal.
The following options may be assigned to the
programmable inputs:
10.1.1 External
Fault
This creates an
External Fault
error message
(E412) on the display. This would be used, for example,
if a crucial external component sent out an error signal.
As it has been assigned as a Fault, this will immediately
cause the machine to shut down.
10.1.2 External
Warning
This creates an
External Warning
message (A615)
on the display. This would be used, for example, if an
external component sent out an error signal. This would
be used for a non-critical component as the machine
would not shut down.
10.1.3 Fault
Dryer
In this feature, the input would be connected to a dryer.
The compressor would shut down in the event of a fault
occurring with the dryer. Fault message E413 would be
displayed.
10.1.4 Warning
Dryer
In this feature, the input would also be connected to a
dryer. Warning message (A608) would be displayed on
the controller screen in the event of a monitored
parameter exceeding the values pre-set on the dryer.
However, the compressor would keep running.
10.1.5
Fault Condens. Drain
This feature would shut down the compressor if the
Condensate Drain unit was faulty. Fault message
(E414) would be displayed.
