1.2.2 Transmitter electronics module and Relay options The transmitter electronics module may be equipped with 4 electromechanical relays or 4 solid-state relays which are mounted to the main terminal board via plastic standoffs. Relay boards are field replaceable by simply unlocking the plastic standoffs with a small flat head screw driver. Remove relay board after unlocking standoffs, insert the replacement relay board, and then lock the plastic standoff with the screw driver. See F

SECTION 2: Wiring and installation 2.1 Field Installation Warning Wiring codes and regulations may vary. ATEX requires that supply connection wiring must be rated at least 5°C above the maximum ambient temperature of 85°C. Wiring must comply with all applicable regulations relating to the installation of electrical equipment in a hazardous area and is the responsibility of the installer. If in doubt, consult qualified personnel before wiring the system. Warning Do not open the tr

Armored Cable preparation procedure: 1. Prepare the armored instrument cable as illustrated in Figure 5 and follow all assembly and/or preparation instructions provided by the cable and/or cable gland manufacturer. 2. Install cable gland and reducer onto the cable. 3. Ensure four (4) inches of wire length is available for connecting to terminals inside the junction box. 4. Use a small flat head screw driver when connecting wires to connector terminals. See Figure 6. 5. Connect sensor w

Warning Before wiring, ensure that power to transmitter is switched off. When connecting cable wires, use a small screwdriver to gently press down and hold the spring connector open. Insert the appropriate wire into the open connector hole, releasing the screwdriver to secure the wire. See Figure 6. Figure 6: Connecting wires Warning Avoid touching electronic components, as they are susceptible to electrostatic discharge (ESD). Refer to Appendix A, “Electrostatic Sensitive De

2.1.4 Remotely mounted sensors jumper configuration Sensor separation from the transmitter may extend up to 2000 feet in which case a junction box is required. When mounting sensor remotely (separating sensor from transmitter), Jumpers JP1 and JP2 should be installed over the pins. Jumpers and pins are located on the main terminal board near the sensor terminals. JP1 is for channel 1 and JP2 is for channel 2. Refer to Figure 8. Figure 8: Separation Jumpers positions

2.1.5 Sensor and Transmitter terminals Warning Before wiring, ensure power to the unit is switched off. Connect the sensor wires to the sensor terminals of the transmitter and connect the transmitter’s power and output terminals to the wiring leading to the Power source/panel. Refer to the configuration tables below for sensor as well as transmitter power and output terminal designations. Table 1: Sensor and Transmitter Terminals Sensor Terminals Transmitter Power Terminals Senso

SECTION 3: Transmitter and faceplate description 3.1 Transmitter Power Up After power is applied to the transmitter, a warm-up routine will begin, the duration of which depends on the sensor type. The display will indicate the sensor warming up and the Status LED will flash Slow Red and current output will be 3.0mA. After the warm-up period, the transmitter will enter normal operation and the screen will display: “Channel 1 00 %LEL (or PPM), Channel 2 00 %LEL (or PPM).” For dual
