  • Page 7: Introduction

    E Point to detect two gases in two separate locations. The E3Point network platform supports different protocols over an RS-485 link, such as Modbus or BacNet MS/TP master. It is well suited for commercial use in certain outdoor environments, and indoor environments, such as parking garages and mechanical rooms.
  • Page 8: Installation

    Installation Installation Locating the Sensor Since the E Point units are shipped with custom network diagrams that indicate best locations for installation, the remaining considerations are installation height and detection obj ectives. If the primary application is the fastest possible leak detection, mount the sensor near the potential leak sources.
  • Page 9: W All Mounting

    Installation W ARNING: Some materials such as, but not limited to, tetraethyl lead, silicones, some sulfur, phosphorus, and chlorinated compounds, may have a poisoning e ect resulting in a loss of sensitivity. W all Mounting Mounting is usually done on concrete walls or columns, but the unit can be mounted on any vertical surface.
  • Page 10 Installation Close the unit cover and tighten screws to 29.7 in-lb (3 Nm). Do not remove PC board when removing knockouts. Knockout on back is not for conduit entry. General Mounting Considerations: Must be easily accessible for calibration and maintenance. Mount the sensor close to the potential leak source for fastest possible leak detection.
  • Page 11: Duct Mounting

    Installation Duct Mounting Special Duct Mount Installation This option works best for airflows between 500–4000 ft./min. The E Point must be duct mounted using the custom box provided with the duct mount version. All of the components housed within the box are factory assembled.

    W iring W iring Guidelines Electrical wiring must comply with all applicable codes. Operating conditions and site equipment that may be involved should be discussed with local operating personnel to determine if any special needs should be considered. Ground the shield at the main control panel. Connect the shield wire in the sensor terminal block labelled shield.

DO NOT connect any wires to these locations. W ire: Signal wiring should be done with #20-24 AW G shielded twisted pair cable Belden 9841 or similar.
  • Page 17: Installation Test

    Installation Test Installation Test Once the unit has been mounted and all wiring connections are complete, a test of the unit’ s functions is recommended. It is necessary to access the unit’ s programming menus to perform the test: Power up the unit and allow 5 minutes for the warm-up procedure to complete (allow 15 minutes for the O sensor).

  • Page 19: Operation

    Operation Operation The E Point gas detection system is factory configured to conform to specific standards. It is designed to be operational after physical installation and warm-up procedures. Start-Up Procedure Before applying power, check all wiring for continuity, shorts, grounds, etc.
  • Page 20: User Interface

    Operation Sensor W arm Up W hen the unit is first powered up, sensors must go through a 5 minute warm-up (15 minutes for the O sensor), during which time the unit displays W arm-Up. The 4-20 mA is maintained at 4 mA for all sensors; however, the O sensor is maintained at (approximately) 17.4 mA (equal to 20.9%).

    Using the Programming Menus Relay Menu The Relay menu allows users to select Latch, Failsafe, or SetDelay. Press enter to access the Relay menu options, then scroll to select Relay #1 or Relay #2. * Menu * Relay Relay #1 Relay Use the arrow keys to scroll to the desired option and press enter to select one of the four following options:...
  • Page 24: Buzzer Menu

    Using the Programming Menus Buzzer Menu The Buzzer menu allows users to select whether or not the built-in audible alarm can be silenced by pressing a keypad button and which events will activate the buzzer. * Menu * Buzzer Press enter in the main Buzzer menu screen. The Buzzer screen displays either Activate or Silence.
  • Page 25: Alarm Menu

    Using the Programming Menus Alarm Menu CAUTION: Only quali ed, knowledgeable personnel should use the programming functions of this unit. Factory settings conform to speci c standards (see Specifications). Any changes made to Alarm Levels may a ect manufacturer’ s stated standards compliance. The Alarm menu allows users to define different alarm levels than the factory settings.
  • Page 26: Restore Menu

    Using the Programming Menus The Hyst(eresis) screen displays. This value, added to the alarm level, tells the unit at which level to deactivate the alarm (e.g. Alarm level A is 25 ppm, minus a hysteresis level of -05, gives a deactivation level of 20 ppm). Use the arrow keys to increase or decrease the value and press enter.
  • Page 27: Temp Menu

    Using the Programming Menus Temp Menu The Temp menu allows users to define the maximum temperature for the device temperature alarm, which can be used to activate the device connected to the relay. * Menu * Temp Press enter to access the Temp menu, then select either Disable or Enable.
  • Page 28: Set Zero Menu

    Using the Programming Menus Set Zero Menu Only use the Set Zero function when the unit no longer displays zero. See Periodic Inspection and Maintenance. This option allows users to set the sensor Zero. In the main Set Zero screen, press enter to begin. If there is a remote sensor connected, you must scroll to select Z1 (built-in sensor) or Z2 (remote sensor).
  • Page 29 Using the Programming Menus Set Span menu W ARNING: If the calibration gas concentration exceeds alarm setpoints, alarms will be triggered. Either change alarm levels so the alarms are not triggered, or put the entire system in service mode so no external equipment (lights, fans, ventilators, buzzers) will be activated.
