High RPM Alarm Delay - The minimum time in seconds
that the RPM is greater than or equal to the High RPM
alarm setpoint before notification of the alarm.
High RPM Shutdown Delay - The minimum time in sec-
onds that the RPM is greater than or equal to the High RPM
shutdown setpoint before the compressor will shut down.
Low RPM Stop Load - If the RPM is less than or equal to this
setpoint, the compressor will be prevented from further load-
ing until the RPM is greater than this setpoint. This setpoint
helps avoid forced unloading.
Low RPM Force Unload - If the RPM is less than or equal to
this setpoint, the compressor will be forced to unload until
the RPM is greater than this setpoint. This setpoint helps
avoid a low RPM alarm or shutdown.
Low RPM Alarm - If the RPM is less than or equal to this
setpoint, for the alarm time delay, an alarm occurs.
Low RPM Shutdown - If the RPM is less than or equal to this
setpoint, for the shutdown time delay, the compressor will
shut down.
Low RPM Alarm Delay - The minimum time in seconds that
the RPM is less than or equal to the Low RPM alarm set-
point before notification of the alarm.
Low RPM Shutdown Delay - The minimum time in seconds
that the RPM is less than or equal to the Low RPM shut-
down setpoint before the compressor will shut down.
Confirmed Running (RPM) - The value that the RPM is
greater than or equal to consider the compressor running.
Starting Maximum Delay - The time delay required for the
Slide Valve to unload below the “Highest Slide Valve posi-
tion to allow starting the compressor” setpoint and the en-
gine RPM’s to reach the “confirmed running” RPM’s set-
point.
