    CHAPTER 2 - INSTALLATION FLUID COMPONENTS, INTL Figure 2-7. Auxiliary Relay Board Wiring Diagram Wiring Remote Enclosure with Auxiliary Relay Refer to the "Wiring the Remote Enclosure" section to run the cable between the local and remote enclosures. In most cases the auxiliary relay board is in the same enclosure as the control circuit. Both boards are mounted on the same panel and have been wired together at the factory.
  • Page 18: Wiring A Remote Control Circuit To A Auxiliary Relay Board

    FLUID COMPONENTS, INTL CHAPTER 2 - INSTALLATION Make sure that the proper relays have been selected for the intended load. See Appendix A for the auxiliary relay board configuration drawing. When connecting the relay wiring, do so with complete understanding of what the process requires of the instrument. The instrument has dual DPDT or single 4PDT relay output contacts dependent on the jumper configuration for each alarm switch point.
