  • Page 17: Power

    Sensepoint XCD RTD Technical Manual SPXCDHMRTEN Issue 1 6.3 Power The Sensepoint XCD transmitter requires a power supply from the controller of between 18Vdc and 32Vdc. Ensure that a minimum supply of 18Vdc is measured at the sensor, taking into account the voltage drop due to cable resistance.

  • Page 18: Cabling

    Sensepoint XCD RTD Technical Manual SPXCDHMRTEN Issue 1 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 RTD Technical Manual SPXCDHMRTEN Issue 1 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.

    Electrochemical sensors should NOT be incinerated as this action may cause the cell to emit toxic fumes. Honeywell Analytics recommends that gas detectors are tested and re-calibrated on a six- monthly basis, or according to site practice. For Sensepoint Toxic sensors that are used either directly with XCD RTD transmitter or remotely mounted in a separate junction box, please refer to individual sensor manual for specific recommended calibration periods.
