Target Pressure – The compressor will vary its speed in order to maintain a
package discharge pressure as close to this value as possible.
Range (in psi): 65 - 145 (non-TAS compressors)
: 65 – 138 (TAS Equipped Compressors)
Automatic Stop Pressure – The compressor will stop if the package
discharge pressure reaches this value and the compressor is running at
minimum speed.
Range (in psi): Target +1 to Target +10
Immediate Stop Pressure – The compressor will stop if the package
discharge pressure reaches this value, regardless of its speed.
Range (in psi): Auto Stop Pressure to Auto Stop Pressure +10

The options set points are similar to the operator set points except these set
points cannot be changed while the unit is running.
Compressor Control – Enabling this setpoint allows the compressor to be
controlled by a serial or Ethernet device, such as an X8I. This is equivalent to

the "Sequencer" option on older Intellisys controllers.
Remote Start/Stop – Enabling this setpoint allows the compressor to be
started and stopped using the digital inputs on the controller.
Enable PoRo – Enabling this setpoint will allow the compressor to
automatically restart after a power outage has been restored if the
compressor was running loaded at the time of the outage. PORO is an option
which must be purchased and installed before this feature can be turned ON.
PoRo Time – Time after the controller power has been restored and
controller has finished booting before the compressor will perform a PORO
start.
Scheduled Start Day – Day (or days) of the week for which a scheduled start
will be performed. The compressor will start when its onboard clock matches
the day, hour, and minute of the scheduled start setpoints. Scheduled Start/
Stop is an option which must be purchased and installed before this feature
can be turned ON.
Scheduled Start Hour – Hour of the day for which a scheduled start will be
performed. Scheduled Start/Stop is an option which must be purchased and
installed before this feature can be turned ON.
Scheduled Start Minute – Minute of the hour for which a scheduled
start will be performed. Scheduled Start/Stop is an option which must be
purchased and installed before this feature can be turned ON.
Scheduled Stop Day – Day (or days) of the week for which a scheduled stop
will be performed. The compressor will stop when its onboard clock matches
the day, hour, and minute of the scheduled stop setpoints. Scheduled Start/
Stop is an option which must be purchased and installed before this feature
can be turned ON.
Scheduled Stop Hour – Hour of the day for which a scheduled stop will be
performed. Scheduled Start/Stop is an option which must be purchased and
installed before this feature can be turned ON.
Scheduled Stop Minute – Minute of the hour for which a scheduled stop will
be performed. Scheduled Start/Stop is an option which must be purchased
and installed before this feature can be turned ON.
Note that in order to disable Scheduled Start/Stop, the Scheduled Start
and Stop days, hours, and minutes must match exactly��

Sensor calibration can only take place when the machine is stopped and
there is no pressure on the sensor. Calibration only needs to take place after
a sensor is replaced, the controller is replaced, the controller software is
upgraded, or the operator suspects the sensor reading is in error. Calibrate
a sensor by selecting the checkbox beside the sensor name. Note that the
checkbox may appear too quickly to be visible. Calibration can be confirmed
by verifying that the sensor value now reads zero.
Each of the sensors listed below can be calibrated.
•
Note that if a sensor is currently reading a value that is ± 10% of its
range from zero, the sensor will not be able to be calibrated and an
warning will be logged in the event log�� Make sure the sensor is being
exposed to atmosphere before attempting calibration��
