Reading Alarm And Control Set Points
In addition to being able to read existing operating conditions, the factory set alarm and control
set points can also be prompted and displayed. The operating variables that are monitored have
preset alarm set points for high and low limits. The air / oil heater and optional air pre-heater also
have a control function to control air temperature.
The systems control and alarm set point values are listed in the table below. Note that the main
oil mist generator reservoir has a non-adjustable low oil level switch that provides an alarm when
the oil level falls below the set level, however there is no programmable set point feature for this
alarm.
