B)Refrigerant Differential Pressure Indication Output:

A 2 to 10 VDC analog output is provided instead of the previous condenser pressure output signal. This signal corresponds to a predetermined minimum and maximum pressure settings setup at commissioning of this feature. This relationship can be altered using the service tool if required.

The “Minimum Delta Pressure “ is typically set to 0 psi and will then correspond to 2 vdc. The “Maximum Delta Pressure “ is typically set to 30 psi and corresponds to 10 vdc.

The Minimum Delta Pressure Calibration setting has a range of 0- 400 psid (0-2758 kPa) in increments of 1 psid (1kPa). The Maximum Delta Pressure Calibration setting has a range of 1-400 psid (7-2758 kPa) in

increments of 1 psid (1kPa). The condenser refrigerant pressure is based on the Condenser Refrigerant Temperature sensor if the Condenser Pressure Option is selected as “Not Installed” at the display.

The evaporator refrigerant pressure is based on the Saturated Evaporator Refrigerant Temperature Sensor.

See CTV-PRB006-EN for additional information about condenser water temperature control.

In this example, 2 vdc corresponds to 0 psi differential and 10 vdc corresponds to 30 psi differential. The min value of 0 psi, and the max value of 30 psi are individually adjustable via the service tool.

Note: Typical settings for CVHE, F, G with refrigerant pumps are as follows.

Min pressure 0 psid (= 2 vdc)

Max pressure 6 psid (= 10 vdc)

Target tower control at 4 psid
