6.5.2 DISPLAY PARAMETERS
The DPC™ Controller is capable of displaying a number of system parameters.
The following summarizes the parameters that can be accessed by the user from
the DPC™ Controller depending on the DPC™ version:
• Chiller Temperature (CHLLR TEMP): The Chiller Temperature is the temperature,
in degrees Fahrenheit, of the air at the coldest point in the air circuit.
• Compressor Status (CMPRSSR): Displays whether the refrigeration compressor
is “ON” or “OFF”.
• Discharge Pressure (P disch): Displays the discharge pressure of the refrigeration
system.
• Suction Temperature (T suction): Displays the suction temperature, in deg. F, of
the refrigeration system. This value is useful in determining superheat of the
refrigerant. (DPC™-Plus Only)
• Suction Pressure (P suction): Displays the suction pressure, in psig, of the refrig-
eration system. (DPC™-Plus Only)
• Inlet Air Pressure and Temperature (P AIR IN / T AIR IN): Displays the tempera-
ture, in °F and pressure, in psig, of the inlet compressed air.
(DPC™-Plus Only)
• Outlet Air Pressure and Temperature (P AIR OUT / T AIR OUT): Displays the
temperature, in °F and pressure, in psig, of the outlet compressed air.
(DPC™-Plus Only)
• Drain Interval (DRN INT): Displays the length of time, in minutes, between
operation of the solenoid drain.
• Drain On (DRN ON): Displays the length of time, in seconds, that the solenoid
drain is open.
• Cumulative Dryer Hours (CUM DRYER HR): Displays the length of time, in hours,
that the dryer has been operational.
Depressing the SELECT DISPLAY button repeatedly scrolls through the above
non-adjustable displays. The Customer Set Points appear at the end of the list
and may be adjusted by the end user to match seasonal refrigeration and drain
operation. These settings are as follows:
• Drain Interval (DRN INT)
• Drain On (DRN ON)
