Diagram 6: Installing the Sensor WARNINGS Care should be taken when removing and refitting the Sensepoint XCD plug-in Sensor to the Sensor Socket so that damage to the connection pins can be avoided. If using an anti-seize compound, the threads should be thinly coated with an approved silicone free compound e.g.
Electrical connections WARNINGS Sensepoint XCD is designed for installation and use in Zone 1 or 2 hazardous areas in many countries including Europe and Class 1 Division 1 or 2 area applications in North America. Installation must be in accordance with the recognized standards of the appropriate authority in the country concerned.
Caution: All electrical connections should be made in accordance with any relevant local or national legislation, standards or codes of practice. The Sensepoint XCD transmitter may be wired in either Current SOURCE or Current SINK configuration. These two options are offered to allow greater flexibility in the type of control system that it can be used with.
Sensepoint XCD Technical Manual SPXCDHMANEN Issue 2 6.2 Terminal connections Note: Ensure that none of the wires in the terminal area cause an obstruction when refitting the Display Module. Ensure that the socket on the Display Module is fully engaged in the Display Module Connector on the Terminal Module.
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.
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.
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.
