CDRP Refrigerant Pressure
Output Option 1A15:
Refrigerant Pressure Output can
be configured at commissioning
to correspond to either A) the
absolute condenser pressure, or
B) the differential pressure of the
evaporator to condenser
pressures.
This output is located at 1A15-
J2-4(+) to J2-6 (ground)
The Output can source a
maximum of 22 mA of current.
A) Condenser Pressure Output.
2 to 10 Vdc corresponds to 0
Psia to the HPC (in Psia) setting.
Temperature based
On standard machines the
Percent Condenser Pressure
Indication Output is based on the
Saturated Condenser Refrigerant
and a temperature to pressure
conversion is made.
If the Condenser Saturated
Temperature goes out of range
due to an open or short, a
pressure sensor diagnostic will
be called and the output will also
go to the respective out of range
value. That is, for an out of range
low on the sensor, the output
will be limited to 2.0 Vdc. For an
out of range high on the sensor,
the output will be limited to 10.0
Vdc.
