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, use rs will receive a detection system which is both versatile and reliable for fast, accurate and continuous monitoring of gases in extreme environments.

THE PRODUCT

TRANSMITTER/CONTROLLER

A Millennium II gas detection system is composed of a field mounted transmitter\controller and Millennium II series sensors which may be integrally mounted to the controller or remotely mounted as far as 2000 feet away.

The transmitter is certified for use in hazardous locations and is available as a single or dual sensor system. All operator controls including configuration and calibration can be accessed without opening the enclosure by using other communication devices and the attached magnet to actuate reed switches. If the area is non-hazardous and the enclosure (housing) is open then the operator may choose to use push-button switches and analog output test jacks on the face of the electronics module. Available outputs are: conventional 0.0 to 20mA analog, Analog/HART, electromechanical relays, solid-state relays or Modbus RTU digital.

A dual channel transmitter is available with "peak picking" functionality where there is only one analog output and this analog output follows the signal from the sensor that is responding to the highest gas concentration. This is useful in conserving analog input capacity on connected user equipment.

THE MANUAL

This manual has been designed to guide users through each procedure, ensuring that transmitters and sensors are configured, operated and maintained properly. Guidelines and warnings are included to ensure safe and proper functioning of the equipment. The manual gives the overall operational and functional features of transmitters

with sensors and may not have sensor speci fic in for mation. Refer to sensor manuals for information specific to each sensor including detailed calibration instructions. If you encounter any problems, see the troubleshooting

section of this manual or contact factory.

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. Sensors may be installed directly to transmitters or remotely using a Certified Net Safety junction box. See Figure 11 when mounting sensor remotely.

1.2.1 Transmitter Orientation Option

Depending on the installation and mounting requirements, the transmitter enclosure (housing) may be mounted in different orientations as seen in Figure 2. To accommodate the different mounting orientations, the electronics module can be rotated inside the transmitter enclosure. See Section ‘1.2.3 Rotating electronics module relative to enclosure and conduit entries’ and Figure 4.

Ensure the orientation allows proper wiring and adequate wire length inside the transmitter enclosure.

When determining suitable enclosure orientation for specific application, installers should observe all local regulations and guidelines for mounting enclosures.

Guidelines

• The safety ground connection of the transmitter is a Green screw found in the enclosure. See Figure 4 for

Ground screw location. Note: The electronics module has to be removed to access Ground screw. Follow steps 1-7 under Section ‘1.2.3 Rotating electronics module relative to enclosure and conduit entries’, when removing electronics module.

• If the 4-20mA signal is not used, connect a jumper between the 4 – 20mA terminal and the Common terminal

to allow analog current levels to be monitored at the Test Jacks on the faceplate.

The use of shielded cable is highly recommended for signal, input, output and power wires. Refer to Section ‘2.1.2 Cable choice and guidelines’ for recommended cable to help eliminate interference caused by extraneous electrical or electromagnetic ‘noise’. To reduce the effect of Radio Frequency signals on the equipment, follow the recommendations listed under Section ‘2.1.2 Cable choice and guidelines’. In applications where wiring is installed in conduit, conduit must not be used for wiring to any other electrical equipment. For effective communication, Net Safety limits sensor separation to 2000 feet using 16AWG wires. Modbus RS-485 connection 2-wire mode, multipoint serial line available. Up to 247 addresses allowed. When developing a RS-485 chain of devices, the last device in the chain requires an end of line termination resistor (120 Ohms). Transmitter connector terminals accommodate wire from 14 to 20 AWG wires.

2.1.1 Seals

equipment should be installed according to local electrical codes. Seals are especially recommended for installations that use high-pressure or steam cleaning devices in proximity to the transmitter and/or sensor. The cementing material used on the Millennium II sensors is suitable for an operating temperature range of (-55 °C to + 85 °C).

The use of conduit wiring seals is recommended to protect the system against water ingression, and

Guidelines

It is recommended that explosion-proof drains and conduit breathers be used. In some applications, alternate changes in temperature and barometric pressure can cause ‘breathing’ which allows moist air to enter and circulate inside the conduit. Joints in the conduit system are seldom tight enough to prevent this ‘breathing’. Threaded connections on the enclosure between the enclosure and conduit pipe need to be sealed with thread tape, such as Teflon tape, or something similar. Hydrophobic filters (IPF-001) may be used to protect sensors from water. 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.

MAN-0148, Rev 1 11 March 2016

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. Selecting the right instrumentation cable and making proper grounding connections within the junction box will reduce or eliminate interference. Visible symptoms of Radio Frequency Interference (RFI) include inconsistent, incorrect and erratic LEL and PPM readings.

Important Wiring Guidelines Fire and gas detection instruments are an important part of a safety alarm and shutdown system. The system is composed of:

• detection instruments

• customer connected equipment

wiring

•

Net Safety designs and manufactures its detection equipment under rigid quality control management systems and makes every effort to design for the harshest of industrial environments. The other components of the system – the customerconnected equipment and wiring – are also important contributors to the overall quality and performance of the safety system. It is important to implement the choice of cable type specified vary from project to project. Poor practices and choices are often found to be the source of unwanted system disruptions. Radio Frequency Interference (RFI) and Electro-Magnetic Interference (EMI) are usually very powerful disruptive forces in industrial facilities and these forces act upon the system through the

Follow the instrument grade, certified for the application conditions, consisting of a rugged protective outer jacket, an overall electrical shield of fine braided copper or metallic foil, and internal pairs or triads of foil shielded copper wire of suitable gauge for the power conducted over the specified length. The shields must be electrically continuous from the instrument junction box through other junction boxes and finally to the connected equipment. The shield must be connected to a suitable ground sink as specified in the instrument manual in order to protect the system from electrical disturbances.

Recommended cable and guidelines The type of cable and shielding practices are especially important when sensor is separated from transmitter via junction box. Net Safety recommends using CSA armored instrumentation cable (ACIC 2PR 16AWG, 300V, ISOS, PVC) when rigid (steel) conduit is not used. See Figure 5. This cable should be used between the PLC/PANEL/DCS and the Millennium II Transmitter, as well as between the Millennium II Transmitter and junction box.

Additional notes: In general, communication cables and power cables should not run in parallel for any significant length, and should not be carried in the same cable tray. Through inductance, high currents in power cables can induce significant ‘noise’ in communication cables running parallel alongside power cables.

See cable preparation procedure on next page.

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.

2.1.7 Sensor Separation/ Remote mounting of sensor

When necessary to mount sensor remotely (separated from transmitter) by way of junction box and conduit, it is important that the installer follow the necessary requirements and guidelines relating to sensor separation and cable selection. See Figure 11 for typical remote mounting of sensor. Also refer Section ‘2.1.2 Cable choice and guidelines’ for cable selection and wiring guidelines. When sensors are being mounted remotely, instructions. Always ensure that the transmitter is supplying 10.5 - 32Vdc across the sensor power terminals (Vdc + and Com (-) ) of Net Safety junction box (JB-MPD-A/S).

The maximum distance between the sensor and transmitter is limited by the resistance of the connecting wiring, which is a function of the gauge of the wire being used. For effective communication, Net Safety limits the separation distance between sensor and transmitter to 2000ft using 16 AWG wire. See Appendix B for information on wire gauge and resistance.

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. Refer to Figure 14 and Figure 15 for test jacks location.

Do not open the transmitter enclosure in a classified area.

3.5 Menu buttons and access

The main menu can be accessed in two ways: Intrusive (opening the enclosure and pressing menu buttons) and NonIntrusive (keeping the enclosure closed and using the magnet and reed switches).

3.5.1 Intrusive Access

The menu buttons provide access to the Millennium II’s Main Menu options allowing the user to review and configure existing options under sub menus and perform calibration.

See Figure 14 and Figure 15.

3.5.2 Non-Intrusive Access/Magnetic Reed switch Access

Accessing the main menu and making a selection can also be done via an attached magnet and Reed switches. The Reed switches are located in the shoe shape print magnets. To select a Reed switch, place and hold the magnet close to the transmitter enclosure at

4.2.1 Full calibration (Normal calibration) procedure

Prior to attempting calibration read and understand the calibration procedure below. Also see

Figure

18 for additional reference.

The following calibration procedure should be followed to ensure an accurate correlation between the output signal and the gas concentration. For accurate performance, the Millennium II is calibrated using 50% span gas. The transmitter will however, allow some flexibility in the use of calibration gas with some sensors; calibration gas outside of 50 % span (10% 60% span gas) will be allowed on specific sensor models (see specific sensor manual for details). The calibration gas value can be chosen by selecting it under “cal. gas value” in the main menu. A full calibration will take approximately 5 minutes to complete.

Ensure the transmitter is functioning properly as indicated by the status LED and current output.

1. Enter the main menu by selecting/activating any key to get the “enter main menu” prompt, then activate

NOTE:

SECTION 5: Monitoring and outputs

5.1Fault monitoring

Self-testing circuitry continuously checks for problems that could prevent proper response. When power is applied to the Millennium II Transmitter, a micro controller automatically tests the system to ensure that it is functioning properly. During normal operation, it continuously monitors the signal from the internal sensor source. In addition, a “watchdog” timer is maintained to ensure the program is running correctly. When a system fault is detected, the Status LED will have a Red fast flash and the fault signal will output a 2.5 mA signal. The transmitter’s event log may be viewed in order to distinguish the fault condition. Refer to the Event Log menu option.

wiring to the transmitter. It is important that external equipment and wiring be checked periodically to ensure they are operational.

The fault detection circuitry does not monitor the operation of external response equipment or external

5.2 Relays

Standard electro-mechanical relays have Form C SPDT contacts rated 5 Amps at 30 VDC/ 250 VAC. There are four physical relays; one Fault and three Alarm relays. These relays have Normally Open and Normally Closed contacts at the output terminals. Solid State relays are Form A contacts rated 2.5 Amps at 60 VAC/DC. These relays also have one Fault and three Alarm relays.

Alarm relays are configurable and can be assigned values; the user is allowed to assign values corresponding to desired alarm conditions, under Relay 1, Relay 2 or Relay 3 for each channel. Relays can be selected to be ‘Energized’ or ‘Deenergized’ and ‘Latching’ or ‘Non-latching’. See “relay assignment” option for reference.

The fault relay output is not commonly used to imitate an automatic shutdown. The fault output indicates a

potential problem with the transmitter not an alarm condition.

5.3 Analog 4-20mA

A 4-20 mA current output is used to transmit the transmitter and sensor status and fault codes to other devices. This output can be wired for isolated or non-isolated operation. A 4.0 mA output indicates normal operation; the transmitter’s output current range is 4.0 - 20.0 mA. For a full list of output current values and what they indicate, see “Sensor Status Registers, Status LEDs, Current Loop, and Display Messages”

RS-485 Modbus RTU protocol is used. Tables 7 and 8 on the following pages give the detailed MODBUS registers and the bit values for the transmitter register.

The Millennium II Transmitter utilizes 2- wire Modbus RS-485 multi serial mode. This Modbus solution implements a 2-wire electrical interface in accordance with the EIA/TIA-485 standards. For this MODBUS configuration, it is important that a third wire be used for connecting all the ‘Common’ (COM) in the chain. Also a 120 Ohm line termination is required for the last device in the line. See Figure 19. The Instrument Engineer is responsible for calculating line length and adhering to MODBUS protocols.

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. Be sure to prevent unwanted response of external monitoring devices and equipment during this procedure. If the Millennium II’s response to calibration gas is within the specified accuracy then it is not necessary to perform a calibration.

Example: When 50% of full scale is applied, the response is expected to be between 11.5 mA (47% of full scale) and 12.5 mA (53% of full scale). An additional consideration is the accuracy tolerance of the calibration gas which may be + or - a few percent. If the calibration gas is + or - 10% of full scale then the reading may be from 10.7 mA (42% of full scale) to 13.3 mA (58% of full scale).

6.2 Troubleshooting

Response to the input should be checked and, if necessary, calibration should be performed whenever the accuracy of this check is not satisfactory. The system should also be checked when sensor or transmitter is added or removed. If problems should develop, first check for faulty wiring, confirm proper voltage to transmitter and attempt a calibration. If problems persist, please contact Net Safety’s Service Department first by phone to try and resolve any issues. If issues cannot be resolved, please follow the procedure on ‘how to return equipment’.

Appendix A: ELECTROSTATIC SENSITIVE DEVICE (ESD)

or induced by an electrostatic field.

The most common cause of ESD is physical contact. Touching an object can cause a discharge of electrostatic energy—ESD! If the charge is sufficient and occurs near electronic components, it can damage or destroy those components.

In some cases, damage is instantaneous and an immediate malfunction occurs. However, symptoms are not always immediate—performance may be marginal or seemingly normal for an indefinite period of time, followed by a sudden failure.

To eliminate potential ESD damage, review the following guidelines:

• Handle boards by metal shields—taking care not to touch electronic components

• Wear grounded wrist or foot straps, or ESD shoes or heel grounders to dissipate unwanted static energy

• Prior to handling boards, dispel any charge in your body or equipment

• Ensure components are transported and stored in static safe packaging

• When returning boards, carefully package in the original carton and static protective wrapping

• Ensure ALL personnel are educated and trained in ESD Control Procedures

In general, exercise accepted and proven precautions normally observed when handling electrostatic sensitive devices. A warning label is placed on the packaging, identifying product using electrostatic sensitive semiconductor devices.

Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic charge caused by direct contact
