Network address
The network address assigns to the driver an address for the serial
connection to a supervisory system via RS485, and to a pCO controller via
pLAN, tLAN, Modbus®.
Parameter/description
CONFIGURATION
Network address
For network connection of the RS485/Modbus® models the
communication speed also needs to be set, in bits per second, using the
parameter "Network settings". See paragraph 6.1.
Refrigerant
The type of refrigerant is essential for calculating the superheat. In
addition, it is used to calculate the evaporation and condensing
temperature based on the reading of the pressure probe.
Parameter/description

1= R22; 2= R134a; 3= R404A; 4= R407C; 5= R410A;6= R507A;

R423A; 19= R407A; 20= R427A; 21=R245Fa; 22=R407F
Valve
Setting the type of valve automatically defi nes all the control parameters
based on the manufacturer's data for each model.
In Manufacturer programming mode, the control parameters can then
be fully customised if the valve used is not in the standard list. In this case,
the driver will detect the modifi cation and indicate the type of valve as
"Customised".
Parameter/description
CONFIGURATION
Valve:
1= CAREL E X V;
2= Alco EX4; 3= Alco EX5; 4= Alco EX6; 5= Alco EX7; 6= Alco EX8
330Hz suggested by CAREL; 7= Alco EX8 500Hz specifi ed by Alco; 8=
Sporlan SEI 0.5-11; 9= Sporlan SER 1.5-20; 10= Sporlan SEI 30; 11=

Danfoss ETS 12.5-25B; 15= Danfoss ETS 50B; 16= Danfoss ETS 100B;
17= Danfoss ETS 250; 18= Danfoss ETS 400; 19= two CAREL E
connected together 20= Sporlan Ser(I)G, J, K.; 21= Danfoss CCM
10-20-30; 22= Danfoss CCM 40
Important:
•
two CAREL E X V valves connected together must be selected if two
CAREL E X V valves are connected to the same terminal, to have parallel
or complementary operation;
•
as described, control is only possible with CAREL E
•
not all CAREL valves can be connected: see paragraph 2.5.
Pressure probe S1
Setting the type of pressure probe S1 defi nes the range of measurement
and the alarm limits based on the manufacturer's data for each model,
usually indicated on the rating plate on the probe.

Parameter/description
CONFIGURATION
Sensor S1
Ratiometric (OUT=0 to 5V)
1= -1 to 4.2 barg
2= 0.4 to 9.3 barg
3= -1 to 9.3 barg
4= 0 to 17.3 barg
5= 0.85 to 34.2 barg
6= 0 to 34.5 barg
7= 0 to 45 barg
21= -1 to 12.8 barg
22= 0 to 20.7 barg
23= 1.86 to 43.0 barg
Important: in case two pressure probes are installed S1 and S3,
they must be of the same type. It is not allowed to use a ratiometric probe
and an electronic one.
Note: in the case of multiplexed systems where the same pressure
probe is shared between multiple drivers, choose the normal option for
the fi rst driver and the "remote" option for the remaining drivers. The same
pressure transducer can be shared between a maximum of 5 drivers.
Example: to use the same pressure probe, -0.5 to 7 bars, for 3 drivers
For the fi rst driver, select: -0.5 to 7 barg
For the second and third driver select: remote -0.5 to 7 barg.
See paragraph 2.6
Note:
•
the range of measurement by default is always in bar gauge (barg).In
the manufacturer menu, the parameters corresponding to the range
of measurement and the alarms can be customised if the probe used
is not in the standard list. If modifying the range of measurement, the
driver will detect the modifi cation and indicate the type of probe S1
as "Customised".
•
The software on the driver takes into consideration the unit of measure.
If a range of measurement is selected and then the unit of measure is
changed (from bars to psi), the driver automatically updates in limits
of the range of measurement and the alarm limits.BY default, the main
control probe S2 is set as "CAREL NTC". Other types of probes can be
selected in the service menu.
•
Unlike the pressure probes, the temperature probes do not have any
modifi able parameters relating to the range of measurement, and
consequently only the models indicated in the list can be used (see
the chapter on "Functions" and the list of parameters). In any case,
in manufacturer programming mode, the limits for the probe alarm
signal can be customised.
