QUANTUM™ HD COMPRESSOR CONTROL PANEL
OPERATION
090.040-O (JUNE 13)
Page 16
In the case of the screen shown, it is Suction Pres-
sure.
Setpoint - This will display the setpoint value that
has been assigned for the Control.
Actual - This will show the Actual value of the Con-
trol input.
Date - The actual date will be displayed at the center
of the Header, to the left of the time. The date must
fi rst be set correctly on the Confi guration screen.
Once set, the date will be automatically adjusted for
at the end of each month, much like the calendar fea-
ture of most modern watches. The primary use of
the date feature is to provide a date stamp for Warn-
ings and Shutdowns.
TIME - The actual time will be displayed in this box.
The time must fi rst be set correctly on the Confi gura-
tion screen. The time will also need to be adjusted for
those locations which observe Daylight Savings Time.
The primary use of the time feature is to provide a
time stamp for Warnings and Shutdowns.
PACKAGE OPERATING VALUES - This box area will show
certain critical package transducer and sensor readings.
Temperature and pressure information as well as motor
related data will be constantly monitored and shown. If
additional are required to be viewed from this screen,
they may be setup and viewed in the System Operating
Values box.
The following 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. 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 ac-
tual temperature of the refrigerant gas en-
tering the compressor .
Discharge
Pressure - Is measured at the compressor
outlet and the value is displayed along with
the unit of measure.
Temperature - Is measured at the compres-
sor outlet 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. 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 ac-
tual temperature of the refrigerant gas exit-
ing the compressor.
Oil
Pressure - The Oil Pressure is measured
prior to entering the compressor and the
value is displayed along with the unit of
measure.
Temperature - The Oil Temperature is mea-
sured prior to entering the compressor and
the value is displayed along with the unit of
measure.
Separator
Temperature - The Oil Separator Tempera-
ture value is displayed along with the unit
of measure.
Filter Differential - If applicable.
Pressure - Shows the pressure drop across
the oil fi lter. The main oil injection oil fi l-
ter pressure drop value (differential) is dis-
played along with the unit of measure.
Economizer - If applicable.
Pressure - The Economizer Pressure is
measured and the value is displayed along
with the unit of measure.
Motor Amps - The actual motor amps.
Motor Recycle Delay - This message shows
the remaining time in minutes for Recycle Delay.
If the compressor has started and shuts down
within the recycle time delay setpoint period, the
Recycle Delay will prevent the compressor from
starting until the delay time expires. This time
delay is intended to prevent damage to the com-
pressor motor from successive restarts.
Note: The remaining recycle delay time can
be cleared from the Motor screen
Motor %FLA - The percentage of the drive mo-
tor full load amperage rating that the motor is
currently using: % (FLA x SF)
Motor Run Hours – The total amount of time in
hours that the compressor motor has run.
Motor Kilowatts Est. - The actual calculation of
the kilowatt usage of the compressor motor. It is
