Ensure that the socket on the Display Module is fully engaged in the Display Module Connector on the Terminal Module.
  • Page 17: Power

    SPXCDHMANEN Issue 2 6.3 Power The Sensepoint XCD transmitter requires a power supply from the controller of between 16Vdc and 32Vdc. Ensure that a minimum supply of 16Vdc is measured at the sensor, taking into account the voltage drop due to cable resistance.
  • Page 18: Cabling

    Sensepoint XCD Technical Manual SPXCDHMANEN Issue 2 6.4 Cabling The use of industrial grade, suitably armoured field cable is recommended. For example, screened 3 cores (plus screen 90% coverage), suitably mechanically protected copper cable with a suitable M20 explosion-proof gland, or ¾” NPT steel conduit, with 0.5 to 2.5 mm2 (20 to 13 AWG) conductors.
  • Page 19: Ground Terminal Wiring

    Sensepoint XCD Technical Manual SPXCDHMANEN Issue 2 The Earth Screen of the field cable should be “tied to Earth” or connected to Ground at one point only. It is common practise to adopt a STAR EARTH connection regime where all instrumentation Screens are connected at one common point.
