  • Page 22 Installation 2. Feed the cable through the cable gland. 3. Turn over the detector module and locate the terminal blocks on the back. Remove the terminal blocks by pulling them toward the center of the module. 4. Connect the cable to the appropriate terminal block, referring to the relevant wiring diagram.
  • Page 23: Ground Connections

    Installation 2.9 Ground Connections Effective grounding is crucial to ensure stable Modbus communications and to limit the effects of radio frequency interference. Ground points are provided inside the back box. In order to prevent false readings or alarms as a result of ground loops, ensure that the shield of all cables are grounded at a single point, preferably at the controller.
  • Page 24: Securing The Detector Module To The Back Box

    Installation 2.10 Securing the Detector Module to the Back Box 1. Remove the front cover from the detector module to expose the four retaining screws as follows: a) Pull the flap on the bottom side to expose the remote gassing port and front cover locking feature.
  • Page 25: Remote Gassing Connection

    Installation 4. Replace the front cover. Place the front cover into the detector module in the position shown and rotate it clockwise until it locks into position. 2.11 Remote Gassing Connection NOTE Use the remote gassing connection for bump test only. Perform calibrations using the calibration cap accessory.
  • Page 26: Commissioning

    Chapter Commissioning NOTE The Sensepoint XCL gas detector is supplied from the factory pre-calibrated. However, it is strongly recommended that the detector response is checked and if necessary, re-calibrated before placing it into service. Refer to Calibration on page 34 for details on the correct calibration procedure.
  • Page 27 Commissioning 2. Remove the detector module of Sensepoint XCL. 3. Configure the sink/source mode of the detector. Refer to Current Source/Sink Selection on page 17 on details of how to do this. 4. Configure the required inhibit level of the detector. Refer to section Inhibit Level Selection on page 17 on details of how to do this.
  • Page 28: Status Indicator

    7. Remove power and refit the detector module to the back box. 8. Refit the front cover. 9. Apply power. The Sensepoint XCL will enter a warm-up mode during which time the status indicator will be steady yellow and the output (mA version) will be held in an inhibited state.
  • Page 29 Commissioning Warning: The indicator alternatively flashes green and yellow when the gas detector is in a warning state. Fault: The indicator flashes yellow when the gas detector is in a fault state. Inhibited: The indicator is on steady yellow when the user has placed the detector into the inhibit state for maintenance or repair.
  • Page 30: Maintenance

    Chapter Maintenance 4.1 Using the Control Buttons It is possible to perform basic maintenance functions on the Sensepoint XCL gas detector without the use of the mobile app. This is achieved through the use of two control buttons inside the detector. Familiarize yourself fully on the operation of these buttons before attempting to use them.
  • Page 31: Maintenance Status Indicator

    Maintenance To escape and discard all changes: This escape function can be used at any time during the procedures detailed in the following sections. Press and hold the DOWN button for 5 seconds. 4.2 Maintenance Status Indicator There is another indicator on the rear of the detector module for easier maintenance.

    Maintenance Calibration gas purge While the calibration gas is purged, the indicator is on steady yellow Cancel When a task is cancelled, the indicator flashes yellow with three short pauses. 4.3 Calibration Cap The following table shows the recommended flow rate and stabilization time for each of the gas types.
  • Page 33 Maintenance 1. Remove the front cover. a) Pull the flap on the bottom side to open it. b) Insert a thin, straight tool, such as a small screwdriver, into the hole to the right of the remote gassing port. c) Apply slight pressure to the tool, turn the cover counterclockwise until it stops.
  • Page 34: Calibration

    Maintenance 5. Refer to the regulator manufacturer for instructions on how to start and stop the gas flow from the cylinder. CAUTION Always use a gas cylinder that is within its expiration date. 4.4 Calibration NOTE On versions that feature the Bluetooth® link, it is preferential to use a smartphone running the app to perform maintenance tasks.
  • Page 35 Maintenance the calibration cap. For details about how to use a calibration cap, see Calibration Cap on page 32. c) Apply fresh air to the detector, and wait for a few minutes until the reading is stable. d) Using the UP and DOWN buttons, adjust the output voltage so that the voltmeter is reading slightly above zero, and then decrease the reading slowly so that it reads zero.
  • Page 36: Bump Test

    Maintenance c) Make sure that the reading voltage out returns to zero. If there is any doubt that the detector is not in fresh air, apply cylinder air. Otherwise, an alarm may occur. 6. Use the cancel function to return to normal monitoring mode. If repeated calibration attempts continue to fail, replace the gas sensor with a new one, and then try again.
  • Page 37: Replacing The Sensor

    Do not replace the sensor without first a) removing power to the Sensepoint XCL or b) placing the sensor into the sensor maintenance mode. Connect your smartphone to the Sensepoint XCL via Bluetooth. Tap the Maintenance button and select Change Sensor. Follow the on-screen instructions.
  • Page 38: Resetting Alarms And Faults

    Maintenance 3. Remove the sensor cover. a) Loosen the screw on the top of the sensor cover. b) Holding the screw, tilt it downwards from the upper edge of the cover. 4. Pull out the gas sensor to remove it. 5.
