The below values are all setpoints
online Pressure – The compressor will load when the package discharge
pressure falls below this value.
Range (in PSI): 65 to Offline Pressure - 10
offline Pressure – The compressor will unload when package discharge
pressure rises above this value.
Range (in PSI): 75 to Rated Pressure + 10. Note that the range will be reduced
by 7 psi when operating a TAS machine.
Lead/Lag – When this box is checked the compressor is operating as a lead
machine. Unchecking the box causes the machine to run as a lag machine.
Lag offset – If the machine is running as a lag compressor, the lag offset will
be subtracted from the online and offline setpoints.
Range (in PSI): 0 – 45, depending on the online and offline setpoints. The Lag
Offset will never allow you to exceed the minimum or maximum values of the
online and offline setpoints.
Mode of operation – Selection for R4-11 is Online/Offline only - determines
how the compressor will try to maintain a specific pressure.
online/offline – The compressor will load the machine by energizing a
•
solenoid that opens the inlet valve and closes the blowdown valve when
package discharge pressure falls below the online pressure setpoint. The
compressor will unload the machine by de-energizing the solenoid when
pressure rises above the offline pressure setpoint.
Unloaded Stop Time – Time period that the machine must run unloaded
before the motor is allowed to stop after a stop command is received.
Range (in seconds): 10 - 30
Starter Time – Time period that the compressor needs in order to come up
to operating speed after a start command before being able to produce air.
Range (in seconds): 5 - 30
The parameters on these pages are adjustable any time.

The below values are all setpoints
Enable Auto-Restart – Enabling this will allow the compressor to stop if it
has been running unloaded for a period of time, and the motor has exceeded
its minimum running time (10 minute in most cases).
Auto-Restart Time – The time period the compressor must run unloaded
before stopping in auto-restart. This time period begins the moment that
package discharge pressure rises above the offline setpoint. Both this time
period and the minimum motor run timer (10 minutes) must be satisfied
before the compressor will stop in auto restart.
Range (in seconds) 2 - 60
Auto-Restart Delay – The time period after the package discharge pressure
has fallen below the online setpoint before the compressor can automatically
restart.
Range (in seconds): 0 - 60
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.
