SUCTION PRESSURE & TEMPERATURE BOX - The
following sensor information is displayed:
• Suction Pressure - Is measured at the
compressor inlet and the value is displayed
along with the unit of measure.
• Suction Temperature - Is measured at the
compressor inlet and the value is displayed
along with the unit of measure.
• Superheat - The temperature of the gas at
saturation temperature for a given period of
time.
DISCHARGE PRESSURE & TEMPERATURE BOX -
The following sensor information is displayed:
• Discharge Pressure - Is measured at the
compressor outlet and the value is displayed
along with the unit of measure.
• Discharge Temperature - Is measured at
the compressor outlet and the value is dis-
played along with the unit of measure.
• Superheat - Superheat is the term used to
describe the difference between the vapor
point (i.e., the temperature at which the
refrigerant evaporates at a given pressure)
and the actual temperature of the refriger-
ant exiting the evaporator coil.
QUANTUM™ LX COMPRESSOR CONTROL PANEL
OPERATION
OTHER PRESSURES AND TEMPERATURE BOX - The
following sensor information is displayed:
• Oil Pressure - The Oil Pressure Is mea-
sured prior to entering the compressor and
the value is displayed along with the unit of
measure.
• Oil Temperature - The Oil Temperature Is
measured prior to entering the compressor
and the value is displayed along with the
unit of measure.
• Filter Differential - If applicable, pressure
drop across the oil fi lter. The main oil in-
jection oil fi lter pressure drop value (dif-
ferential) is displayed along with the unit of
measure.
• Separator Temperature - The Oil Separator
Temperature value is displayed along with
the unit of measure.
• Process Temperature - If applicable, the
Leaving Process Temperature value is dis-
played along with the unit of measure.
• Balance Piston - If applicable, the Balance
Piston pressure reading is displayed along
with the unit of measure. This reading is a
measurement of the presence at the Bal-
ance Piston.
