INTRODUCTION Building on the outstanding legacy of the Millennium Series, Net Safety’s latest innovation in this line of continuously evolving industrial transmitters and sensors, the Millennium II, pushes the boundaries of what you can expect from your detection system. Combined with state of the art “Smart” sensors, users will receive a detection system which is both versatile and reliable for fast, accurate and continuous monitoring of gases in extreme environments.
Enclosure Dimensions The Millennium II Transmitter enclosure is available in Aluminum (AL6061) and Stainless Steel (SS316). Dimensions are in inches and millimeters.
SECTION 1: Installation 1.1 Unpack Carefully remove all components from the packaging and check them against the enclosed packing list. Inspect all components for obvious damage such as broken or loose parts. If you find any components missing or damaged, notify the representative or Net Safety Monitoring, immediately. 1.2 Mounting Ensure transmitter and sensor are securely mounted, taking into consideration all requirements.
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.
1.2.3 Rotating electronics module relative to enclosure and conduit entries The electronics module consists of the relay board and faceplate (Display/CPU assembly) with main terminal board. To rotate the electronics module, follow these instructions: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Turn off power to transmitter and ensure area is de-classified. Remove the enclosure cover. Unscrew both the locking knobs and free from two metal standoffs. Lift transmitter faceplate from enclosure.
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.
It is the responsibility of the installer to install conduit seals where necessary, and to design conduit runs to ensure that condensation does not accumulate and collect inside the enclosure. 2.1.2 Cable choice and guidelines Radio Frequency Interference (RFI) can be caused by nearby electrical devices (transformers, high voltage equipment) as well as handheld communications devices/radios, which when activated, may impede the proper functioning of the transmitter and sensor.
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.
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 Device (ESD)”. 2.1.
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.
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.
2.1.6 Remote Reset If the alarm relays are configured for latching operation it may be desirable to reset latched alarms from a remote location. In this case a normally open, momentary push-button switch may be connected across terminals RST and COM. Figure 10: Remote Reset wiring 2.1.
2.1.8 Wiring drawings Wiring drawings show general ways in wiring the system for analog signal output. Consult qualified personnel on specific wiring requirements.

2.1.9 Installation Checklist Prior to operation, it is important to do the following checks. Ensure transmitter and sensor are properly and firmly mounted. Ensure that the enclosure certified stopping plug is tightened to unused conduit entry/opening, to maintain ingress protection and flameproof type protection. Ensure transmitter and sensor are not being obstructed; transmitter and sensor are accessible and target gas is not inhibited from reaching sensor.
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).
3.3 Status LED The Status LED can be solid Red or Green, or flashing Red or Green to indicate various states of the transmitter and sensor. Refer to “Sensor Status Registers, Status LEDs, Current Loop, and Display Messages”. 3.4 Current loop measurement (Test jacks) For convenience, a pair of test jacks for each analog output is provided on the front face of the display module. Attach mA meter probes to these jacks to check loop current without opening the circuit to insert the meter.

SECTION 6: Maintaining 6.1 Periodic response check Net Safety Monitoring recommends that a bump test be performed every 90 days to ensure continued functionality and accuracy of the detection system. Full calibration is recommended when the sensor fails to meet acceptable accuracy standards. This involves the application of calibration gas to the sensor, then the observation of the response LEDs, analog output, and external monitoring equipment.
6.3 Storage The transmitter and its electronic components/parts should be stored in locations free from dust and moisture. The storage temperature should be well within the limits of the certified temperatures. See Appendix C for certified temperatures. 6.
