Discharge Pressure alarm setpoint before notification
of the alarm.
Shutdown Delay - The minimum time in seconds that
the Discharge Pressure is greater than or equal to the
high Discharge Pressure shutdown setpoint before the
compressor will shut down.
If “dual discharge control” has been enabled in Factory
Setup, either Mode 1 or Mode 2 setpoints must be chosen.
CONTROL SETUP -
COMPRESSOR SAFETIES - ”SUCTION SAFETIES” SCREEN
“Activated” will be shown at the control setpoints that have
been selected. The following special selection keys are on
this display:
[High Discharge Mode 1] - Is shown if Mode 2 is acti-
vated so that the operator can change to mode 1 set-
points.
[High Discharge Mode 2] - Is shown if Mode 1 is activated
so that the operator can change to mode 2 setpoints.
High Suction Pressure Shutdown - If the Suction Pres-
sure is greater than or equal to this setpoint, for the
shutdown time delay, the compressor will be shut down.
Alarm Delay - the minimum time in seconds that the
Suction Pressure is greater than or equal to the high
Suction Pressure alarm setpoint before notification of
the alarm.
Shutdown Delay - The minimum time in seconds that
the Suction Pressure is greater than or equal to the
high Suction Pressure shutdown setpoint before the
compressor will shut down.
The following suction pressure setpoints are on this control
setpoint display:
High Suction Pressure Stop Load - If the Suction Pres-
sure is greater than or equal to this setpoint, the com-
pressor will be prevented from further loading until the
Suction Pressure is less than this setpoint. This set-
point helps avoid forced unloading.
High Suction Pressure Force Unload - If the Suction
Pressure is greater than or equal to this setpoint, the
compressor will be forced to unload until the Suction
Pressure is less than this setpoint. This setpoint helps
avoid a high Suction Pressure alarm or shutdown.
High Suction Pressure Alarm - If the Suction Pres-
sure is greater than or equal to this setpoint, for the
alarm time delay, an alarm occurs.
