7.3 CONNECTION TO IPRO
7.4 CONNECTION TO ANALOGUE INPUTS
7.4.1 Temperature probes (NTC and PTC)
2-row sensors that do not require polarity to be respected.
Each sensor must be connected through one of the inputs (from Pb1 to Pb10) and
the common (PbC) as shown in the diagram below.
Recommendations:
- follow the diagram of the
device
used,
for
the
numbering.
- the configuration is
determined
by
the
application.
- if used as a digital input
(potential free - not live),
use the same connection
configuration as of the
sensors.
7.4.2 Pressure transducers and current probes (4 - 20 mA)
2-row sensors that r12Vdc power supply.
Each sensor must be connected through one of the inputs (from Pb1 to Pb10) and
the power supply (+12V) as shown in the diagram below.
Recommendations:
- follow the diagram of
the device used, for the
numbering.
- the configuration is
determined
by
the
application.
7.4.3 Pressure transducers and ratiometric pressure transducers (0 - 5V)
3-row sensors that r5Vdc power supply.
Recommendations:
- follow the diagram of the
device
used,
for
the
numbering.
-
the
configuration
is
determined
by
the
application.

CONNECTION TO XEC SUPERCAP
The XEC device and the XEV20D driver must be powered by two different
transformers; failure to observe this warning can cause damage to the XEC device or
to the XEV20D driver.
With a connection to the XEV20D driver, to control two electronic expansion valves,
two XEC modules must be used.
For both XEC modules, observe the correct power supply connection sequence
(connectors 1 of the XEC modules connected to the same pole of the transformer,
connectors 2 of the XEC modules connected to the other pole of the transformer).
8.1 CONNECTION TO THE XEV20D DRIVER WITH JUST ONE CONNECTED
VALVE
8.2 CONNECTION TO THE XEV20D DRIVER WITH TWO CONNECTED VALVES
