HIGH PRESSURE MODULE  

Address = 96

Supply voltage to high pressure module

The power supply can be taken from the main module. It is 
important that + is connected to +.

Battery

Ensure that the valve closes if there is no supply voltage.

Stepper valve 

FX ventil type CCMT. 
Connector:
5: WHITE
6: BLACK
7: RED
8: GREEN

Canbus

Data communication to the main module.

Sensor inputs

• Pt 1000 ohm, AKS 11 or  AKS 21.

Contact input AUX 2

Signal from oil level, 
or input for fan alarm or another alarm.

Relay output AUX 2

Activation of de-superheating or hot gas dump.

RECEIVER MODULE    

Address  = 97

Supply voltage to high pressure module

The power supply can be taken from the main module. It is 
important that + is connected to +.

Battery

Ensure that the valve closes if there is no supply voltage.

Stepper valve 

FX valve type CCMT. 
Connector:
5: WHITE
6: BLACK
7: RED
8: GREEN

Canbus

Data communication to the main module.
The section must be terminated using a 120 ohm resistor.

Contact input AUX 3

Signal from heat recovery, 
or input for fan alarm or another alarm.

Relay output AUX 3

Activation of heat recovery, 
or AUX 3 output for de-superheating or hot gas dump.

MAIN MODULE

AO - Analog output, 3 pcs. AO1, AO3, AO4

Must be used if using frequency converters or EC motors. 
Connect 24 V on N and L (separate power supply) Avoid earth 
fault current.
 - Use double-insulated transformer. The secondary side must 
not be earthed. 
Obtain 0-10 volts from terminals Com-AO1, N-AO3 and N-AO4. 
PAY ATTENTION TO THE POLARITY of N.
(AO3 and AO4 are galvanically isolated. AO1 is not).

AI - Analog inputs, 

Pressure transmitters, 4 pcs. AI1 - AI4

Temperature sensors, 4 pcs. AI5 - AI8

• Pt 1000 ohm, AKS 11 or AKS 21.

DI - Digital switch inputs, 8 pcs. DI1 - DI8

The connection may be a shut-down or interruption function. 
Select what is to be activated during configuration.
(DI3 can be used as an AUX1 input, but only if regulated with 2 
MT compressors).

Supply

24 V a.c. or d.c. Class II is required.

17 VA

EXD 316, HP 

10 VA

EXD 316,  rec 

10 VA

Stepper valve, HP  _ _VA
Stepper valve rec.  _ _VA

Canbus

Communication to the high pressure module and to the receiver 
module
"L" to "L" and "H" to "H" 
A jumper must be connected between "H" and "R".
Terminate on the receiver module with a resistance of 120 ohm. 
If mounting an external display, the termination must be done 
differently. See next page.

Important!
In order to set the addresses 96 and 97, you must follow the re-
commended procedure. See next page.

Modbus

It is important that the installation of the data communication 
cable is carried out correctly. See separate literature, no. RC8AC.
Remember termination at the termination points.

DO - Digital outputs, 8 pcs.  DO1-DO8

DO5 and DO6 are solid state relays. The outputs are used for 
connecting a Bitzer CRII. If a Bitzer CRII is not being connected, 
output DO6 can be used for activation of an oil valve.
The relays are de-rated to the specified values.
The alarm relay will be driven under normal operation and 
will drop in the event of alarms and insufficient voltage to the 
controller.  
(DO3 can be used as an AUX1 output, but only if regulated with 
2 MT compressors).
