setpoint period, the Recycle Delay will prevent the com-
pressor 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 Control" display.
•
Pumpdown Delay - This message shows the remain-
ing time in minutes for pumpdown delay. If the com-
pressor is in Pumpdown, the Pumpdown Delay will
prevent the compressor from stopping until the delay
time expires or the suction pressure falls below the "On
when above" pumpdown setpoint. This time delay is
intended to provide enough time to remove the refrig-
erant gas.
Note: While in pumpdown, the delay time and the "On
when above" setpoint can be overridden to force the
compressor to stop by pressing the [Compressor
Stop] screen command key again.
COMPRESSOR ALARM STATUS BOX:
The alarm status is displayed in the indented box below the
Compressor status box. The status box is blank with no
message if there are no alarms or shutdowns present.
One of the following messages could be shown:
•
ALARM - This message flashes when an alarm is
present. An alarm is a condition that requires an op-
erator to acknowledge it and allows the compressor to
continue to run if it is running.
•
SHUTDOWN - This message flashes when a shutdown
is present. A shutdown is a condition that requires an
operator to acknowledge it and causes the compres-
sor to shut down. If the compressor cannot be stopped,
it is minimally run in a protected state.
An Alarm or Shutdown message indicates an Alarm or Shut-
down point has been reached, or exceeded. Select the
[Alarms/Shutdown] key from the "Main Menu" display for
details. For additional shutdown information, select the
[Alarms/Shutdown] key from the "Main Menu" display and
then the "Freeze" display.
When a Shutdown occurs, the display backlight will flash 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 flashing backlight.
SETPOINT BOX:
The following items are shown:
•
Setpoint - This is the current control setpoint maintained
by the internal capacity control.
•
Actual - The current reading of the pressure or tem-
perature that was chosen as the compressor control
setpoint.
