Capacity control of the compressor depending
on the evaporation pressure using the extension
module for pressure control (option)
Installation of the extension module kit (part number
347 972 01):
• Plug the extension module into the top slot of the FI
control module and tighten the screw.
• Ratiometric pressure transmitter
– Install the pressure transmitter labelled
"2CP5-71-49" on the low-pressure side.
– Install the pressure transmitter labelled
"2CP5-71-47" on the high-pressure side.
– In the case of Schrader valves, install the pres-
sure transmitters without a copper gasket ring to
ensure safe opening.
For the wiring of the extension module, see schematic
wiring diagram.
Function and technical data of the extension module
• X1: 1, 2 and 3
– Input for ratiometric low-pressure transmitter.
– Correct function is indicated by blue LED.
• X1: 4, 5 and 6
– Input for ratiometric high-pressure transmitter
– Correct function is indicated by red LED.
• X2: 1
– Analogue output for transmitting the low-pressure
value to the FI (X11: 1: AI1).
• X2: 2
– Analogue output for transmitting the high-pressure
value to the FI (X11:2: AI2).
• X3: 1
– Input for 24 V DC power supply coming from the
FI (X12: 5).
• X3: 2, 3, 4, 5 and 6
– 24 V DC outputs.
– Allow simple wiring of the digital inputs of the fre-
quency inverter.
• X4: 4
– Digital output for automatic detection of the exten-
sion module by the frequency inverter
(X12: 3: DI6).
• X4: 5
– Digital input for receiving the start command for
the 2nd compressor from the frequency in-
verter(X12: 4: DO3).
– Switches the relay X5.
• X5: 1 and 2
– Potential-free relay for starting the 2nd com-
pressor.
– Max. voltage: 250 V AC.
– Protection from inductive or capacitive loads must
take place by external measures.
– Max. current: 6 A of resistive load.
