Control System Components

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 vdc output is located at 1A15 – J2 – 4 (+) to J2-6 (Ground)

The Voltage DC Output can source a maximum of 22 mA of current.

This output is Voltage DC only, 4- 20mA is not supported.

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.

Pressure based

With the Enhanced Protection EPRO option, a condenser pressure transducer is installed and the pressure is measured.

If the Condenser Pressure sensor goes out of range due to either an open or short, a pressure sensor diagnostic will be called and the output will go to end of range low. That is, for an out of range low on the sensor, the output will be limited to

2.0VDC. For an out of range high on the sensor, the output will be limited to 2.0 VDC.

Note: Controls allow Delta Pressure or condenser pressure output, but not both.
