CAPACITY/VOLUME - Shows what is presently con-
trolling the Slide Valve and from what source it was
initiated. The following sources may be shown:
Capacity:
• Manual
• Automatic
• Remote -- Communications
• Remote -- IO
• Remote -- 4-20 Input
• Remote -- Sequencing
• Manual -- Browser
VOLUME:
• Manual
• Automatic
RUN HOURS – The total amount of time in hours that
the compressor motor has run.
WARNING/SHUTDOWNS STATUS BOX - The Warn-
ing/Shutdowns Status is displayed below the Capac-
ity/Volume status box. This status box is blank with
no message if there are no warnings or shutdowns
present.
If a Warning or Shutdown occurs, a fl ashing mes-
sage will be shown, identifying the type of warning or
shutdown. As an example, if the Oil Temperature has
been less than or equal to the Low Oil Temperature
Warning setpoint for its time delay setting, then a
Low Oil Temperature Warning will be shown. If the
warning is not cleared by the operator, and the Oil
Temperature continues to drop to a point that is less
than or equal to the Low Oil Temperature Shutdown
setpoint for its time delay setting, then a Low Oil
Temperature Shutdown is issued, and the compres-
sor, if running, will stop. The defi nitions for the two
types of messages are as follows:
WARNING - A specifi c warning message fl ashes
when a warning is present. A warning is a con-
dition that requires operator acknowledgement
but allows the compressor to continue to run if it
is already running.
A Warning message indicates that a warning
setpoint has been reached, or exceeded.
SHUTDOWN - This specifi c shutdown message
fl ashes when a shutdown is present. A shutdown
is a condition that requires an operator to ac-
knowledge, and causes the compressor to shut
down.
A Shutdown message indicates that a shut-
down setpoint has been reached, or ex-
ceeded.
When a Shutdown occurs, the display back-
light will fl ash on and off to alert an operator

of the shutdown. This visual alarm will help
get the attention of the operator in a noisy
engine room environment where audible
alarms may not be heard. Pressing any key
on the keypad will clear the fl ashing back-
light.
OIL LUBRICATION DEVICE STATUS BOX - The oper-
ating status is shown for the following devices:
• Oil Pump - (If selected in the Confi guration)
– The On or Off message is shown for the
status of the oil pump. The Manual or Auto
message is shown to indicate the position of
the HAND-OFF-AUTO switch. If dual pump
control was enabled in Confi guration, the
lead pump (either Oil Pump 1 or Oil Pump
2) is shown.
• Oil Heater - The On or Off message is
shown for the status of the oil separator
heater(s).
MOTOR STATUS BOX - The following items are
shown:
• Motor Amps - The actual motor amps is
shown.
• %FLA - The percentage of the drive motor
full load amperage rating that the motor is
currently using: % (FLA x SF)
• Kilowatts - The actual calculation of the
kilowatt usage of the compressor motor. It
is based on the calculation of KW = (√3 x V
x A x PF) / 1000.
• Recycle Delay - This message shows the
remaining time in minutes for Recycle De-
lay. 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 compressor motor
from successive restarts.
Note: The remaining recycle delay time can
be cleared from the Motor screen
COMPRESSOR STATUS BOX - Shows the present
operating status of the compressor and from what
source it has been initiated:
Compressor Mode - One of the following mes-
sages is shown:
• Manual - A compressor manual start or
stop command was sent.
• Automatic - The compressor auto com-
mand was sent. The compressor starting
and stopping is being controlled from auto-
matic cycling control setpoints at the panel.
