  • Page 2 The system pressure is controlled via a single point in the system. This is not a cascading pressure control scheme. The X8I features an Energy control mode that takes the guesswork out of manually programming the schedules and sequence of multiple compressor systems.
  • Page 3 Using the real-time clock feature and pressure schedule functionality, the X8I can be instructed to change among the tables at any time based on time of day and day of the week. This functionality allows the X8I to switch among multiple different system configurations without disruption to control.
  • Page 4 X8I front panel. Configurable Auxiliary Input/Output (I/O) Contacts The X8I is equipped with auxiliary I/O contacts that can be configured to control the X8I and the system components or to activate remote alarms.

  • Page 5: Installation

    It should be free of flow restrictions, excessive pressure drops and excessive demand surges. A common receiver tank is an excellent choice. The pressure transducer can be located up to 330 ft (100 m) from the X8I.

  • Page 7: Operation

    Compressors can be maintained off-line to minimize losses due to system leaks in pressurized systems idle during non-productive periods. Once the X8I is properly set up it will operate automatically. Every X8I comes preset from the factory in ENER mode and with typical default settings. For more information, please reference the X8I Quick Set-Up Guide.
  • Page 8 These products are supplied and ordered separately depending on the compressors to be connected. Compressor Interface Each air compressor in your system must be interfaced to the X8I. Interface methods may vary depending on the compressor type and/or local control configuration. Currently, all compressors with the exception of the recently introduced R-Series fixed- speed contact-cooled rotary compressor, will connect via either an ir-PCB (hardwire connection) or an ir-485/irV-485 Gateway (RS485 connection).
  • Page 9 The ir-PCB expansion module is suitable for wall mounting and must be located adjacent to the X8I unit (max 33 ft or 10 m).
  • Page 10 VSD box; in some cases, a CT is installed on the drive to determine compressor speed. Multiple VSD boxes can be connected to the X8I as long as the number of compressors does not exceed the maximum number of compressors (8). The VSD box connects to the X8I controller via the two-wire RS485 network.
