6. Compressor module (STD)
31
6.4 Connection to the GD Connect 12
The module is connected to the GD Connect 12 via the
built-in RS485 interface.
The wiring diagram showing how to connect the RS485
interface to the GD Connect 12 can be found in the
annex.
The DIP switch settings for addressing the module and
for switching bus termination on and off are also listed
there.
6.5 Connection to the compressor
Note
The connection of the compressor module (STD) as
shown in this document is intended as a guide for the
majority of compressor control systems in use. Some
compressors differ in terms of operation and/or function;
consult your compressor supplier/specialist for advice.
Wiring diagrams with examples showing how to connect
a compressor control to the module can be found in the
annex.
Danger
Switch off the power supply to the compressor,
before connecting the compressor module (STD) to
the compressor control.
Digital inputs
The module detects the compressor status via three
digital inputs, which are indicated via three LEDs on the
module.
A voltage in the range from 24 to 230V AC or DC can
be connected at each input.
Each input is routed to three terminals:
"24..48VUC" terminal
"110..230VUC" terminal
"COM" terminal
Note that the voltage used signal must be routed to the
appropriate terminal.
Important
Do not connect voltages of more than 250V to the
inputs.
If the voltages used exceed 250V, an auxiliary
contact must to be used to switch a suitable voltage
to the inputs.
The inputs may only be connected to power circuits
with appropriate fuse protection.
