Net Safety Monitoring Inc.
INTRODUCTION
The Millennium series is Net Safety's latest innovation in a line of continuously evolving industrial gas detectors. The microcontroller based system provides fast,
accurate and continuous monitoring of gases in extreme environments.
THE PRODUCT
The Millennium Basic is an analog output, explosion-proof, Class 1, Division 1 for hazardous areas, combustible gas detector for use with the SIR100 sensor
(methane/propane or methane/butane).
THE MANUAL
The manual has been designed to make installation of the Millennium product easy. To ensure proper installation, follow the 7 simple steps outlined in the following
pages. Throughout this manual are tips and warnings to make your installation experience more efficient. If you encounter problems during operation, consult the
troubleshooting section or contact your sales representative.

STEP 1 — PLAN
LOCATE CONTROLLER/SENSOR
Figure 1: Locate Sensor/Controller
Prior to the installation process, a location plan for placing the Controller and
Sensor should be developed. Although there are no absolute rules for
determining the quantity and location of a sensor or controller, the following
points should be considered when planning the installation.
• Locate the Controller where it will be accessible and visible.
• Carefully locate the sensor in an area where gases may potentially
accumulate.
• Use redundant systems to enhance protection and reliability.
• Light gases tend to rise; heavy gases tend to accumulate in low areas.
• Consider air movement patterns within the facility.
• Consider the construction of the facility (such as trenches where heavy gases
may accumulate or peaks where light gases may accumulate).
• Seek advice from experts knowledgeable about the primary gas to be
detected.
• Use common sense and refer to various regulatory publications that discuss
general guidelines for your industry.
The two most common installation options are as follows:
Option 1
The Sensor is attached directly to the Controller. A calibration cup is slipped
onto the bottom of the Senor and the gas is attached to the side calibration
fitting.

Controller
See "Wiring—Controller and Sensor" on page 9 for detailed instructions.
Option 2
Locate Sensor separate from Controller using a Junction Box.
The Controller is located at eye-level, while the Sensor is located where gas is
most likely to accumulate (for example, high up for a light gas). Conduit then
connects the two devices. A calibration cup is slipped onto the Sensor to
concentrate the gas and the calibration gas.
TIP:
The Calibration Cup prevents air circulation affecting the calibration
process and concentrates the gas during calibration. If the Calibration
Cup is not used, the area must be free of drafts or wind and the flow
rate of calibration gas must be 3.0 liters per minute or greater.
See "Wiring—Sensor Separation" on page 10 for detailed instructions.

STEP 2 — INSTALL
UNPACK
Carefully remove all components from the packaging. Check components
against the enclosed packing list and inspect all components for obvious
damage such as broken or loose parts.
If you find any components missing or damaged, notify the distributor or Net
Safety Monitoring immediately.
THE CONTROLLER HOUSING
4.850
The Housing is explosion-proof, Class 1, Division 1, Groups C, D for hazardous
applications.
It is designed a 1-man, intrusive calibration.
The Sensor can be attached directly to the Housing or separated using a junction
box.
To remove the cover, simply screw the cover counter clockwise.
THE SENSOR
There are two types of SIR 100, combustible gas sensors; 0-100% LEL for
methane/propane or methane/butane detection.
ML1050E-SIR100 7
Net Safety Monitoring Inc.
STEP 3 — WIRE
FIELD INSTALLATION
WARNING:
Wiring codes and regulations may vary. Compliance with regulations is the
responsibility of the installer. Wiring must comply with applicable regulations
relating to the installation of electrical equipment in a hazardous area. If in
doubt, consult a qualified official before wiring the system.
• If the 4-20 mA signal is not used, connect a jumper between the 4-20 terminal
and the Common terminal.
• The use of shielded cable is highly recommended for signal, input, output and
power wires to protect against interference caused by extraneous electrical or
electromagnetic 'noise'.
• In applications where the wiring cable is installed in conduit, the conduit
must not be used for wiring to other electrical equipment.
• The maximum distance between the Sensor and Controller is limited by the
resistance of the connecting wiring, which is a function of the gauge of the
wire being used.
• The Controller contains semiconductor devices susceptible to damage by
electrostatic discharge. Use caution when handling. For more information on
proper ESD handling, refer to the Appendix A.
SEAL
• Water-proof and explosion-proof conduit seals are recommended to prevent
water accumulation within the enclosure.
• Seals should be located as close to the device as possible and not more than
18 inches (46 cm) away.
• Explosion-proof installations may require an additional seal where conduit
enters a non-hazardous area. Ensure conformity with local wiring codes.
• When pouring a seal, use a fibre dam to assure proper formation of the seal.
Seals should never be poured at temperatures below freezing.
• The jacket and shielding of the cable should be stripped back to permit the
seal to form around the individual wires. This will prevent air, gas and water
leakage through the inside of the shield and into the enclosure.
• 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'.
MOUNT
The Controller should be mounted at eye-level and be easily accessible for
calibration and maintenance purposes. The Sensor should be placed where gas
is likely to accumulate.
To avoid water damage to electronic components, ensure the Sensor is installed
under the explosion-proof Controller. To further prevent water damage, seal
conduit at all points of entry to the Controller or junction box.
The Sensor may be installed directly to the Controller or may be mounted
separately using a junction box (see "Wiring—Sensor Separation" on page 10).

WIRING—SENSOR SEPARATION
As the Sensor must be located where gas is likely to accumulate and the
Controller where it can be easily reached, it is often necessary to “separate” the
Controller and Sensor.
The Sensor separation kit (JB2-4-ASSY) is composed of a junction box and
terminal strip. Refer to Option 1, Figure 1, "Locate Sensor/Controller", on
page 6 for an example.
Shielded copper instrument wire (minimum 18 AWG) should be used for
separations up to 1000 feet.
Shielded copper instrument wire (minimum 16 AWG) should be used for
separations up to 2000 feet.
Contact Net Safety if separation above 2000 feet is required.
Ensure that the appropriate wire is used for the Class 1/Division 1, hazardous
applications.
Note: If the 4-20 mA signal is not used, connect a jumper between the 4-20
terminal and the Common terminal.

STEP 5 — CALIBRATE
CALIBRATE SENSOR
WARNING: The calibration procedure requires about 5 minutes to complete. If gas is not applied at the appropriate time, a calibration failure may occur (refer to
"Calibration Failure" on page 14 for specific information).
Recommendation: Power up the unit for at least 4 hours BEFORE first calibration.
For proper performance, the Millennium should be calibrated using 50% full scale of the specific gas of concern. The concentration of gas, corresponding to 100%
of full scale, is converted to a linear 4 to 20 mA output signal which can be powered from the primary DC supply of the instrument.
The following calibration procedure should be followed to ensure an accurate correlation between the 4 to 20 mA output signal and the gas concentration.
Calibration Procedure
1. Confirm successful power up of Controller—LED green blip/blink every 2 seconds; no fault indicated.
2. Connect a standard current meter to the Controller’s Test Jacks.
3. Press and hold the Calibration Switch for 10-15 seconds.
4. When 3 mA displays and Status LED Green, solid, apply zero gas (clean air).
Recommendation: Flow certified ZERO AIR at a rate of 1.0 litres per minute through the side calibration fitting, when using the calibration cup (if separated or
not using the calibration cup , a rate of 3.0 litres per minute is recommended).
5. When 3.3 mA displayed, apply specific gas (50% of full span). During gas application, LED will fast flash red.
6. When 3.6 mA displayed and LED solid green, remove gas.
7. Apply zero gas (clean air) again to purge system.
8. Controller will return to normal operation.
Note: Always apply test gas after calibration to verify operation.

Calibration Failure
If the calibration procedure fails, the Status LED alternates red and green
flashes and the analog output changes back and forth from 3.0 to 3.3 mA.
The unit remains in a failed state until manually reset.
Manual Reset
A Manual Reset is required after a calibration failure or to clear an alarm.
Simply place and hold the Magnet against the Reed Switch or press and hold the
Calibration Switch for 3-5 seconds. The unit will return to the normal operation
using previous calibration values if not calibrated for service.
STEP 6 — MONITOR
SENSOR FAULT
WARNING: The fault detection circuitry does not monitor the operation of
external response equipment or the external wiring to these devices. It is
important that these devices be checked periodically to ensure they are
operational.
To ensure proper response, the Millennium features self-testing circuitry that
continuously checks for problems. When power is applied, the system
automatically begins a test to ensure proper functionality.
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
flashes fast red and current output displays 2.5 mA.
SENSOR LIFE
NORMAL
With no gas present and no fault detected, green LED will blip/blink and analog
output will display as 4.0 mA.
OUTPUT
A 4-20 mA DC current output is used to transmit the alarm 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; a >4.0 - 20.0 mA output indicates
the presence of gas.
Current output of 2.5 mA indicates the presence of a system fault; 3.0 to
3.3 mA indicates calibration failure.
STEP 7 — MAINTAIN
Net Safety Monitoring recommends a response check every 3 months. 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 response to calibration gas is within the
specified accuracy then it is not necessary to perform a calibration. For
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).
Depending on various factors, sensor response may slowly deteriorate over a
period of years. If calibration becomes impossible for any reason, the analog
output will switch repeatedly between 3.0 mA and 3.3 mA and the red and green
LEDs flash.
Install a new SIR100 Sensor and re-calibrate. The calibration function
automatically adjusts span amplifier gain across a broad range without any need
for manual adjustment of potentiometers or jumpers.
ML1050E-SIR100 14
Net Safety Monitoring Inc
STEP 8 — TROUBLESHOOT
Response to the input should be checked and, if necessary, calibration should be
performed whenever any of the following occur.
• Sensor or transmitter supplying a signal to the Millennium is added or
removed
The Millennium is not designed to be repaired in the field. If a problem should
develop, first calibrate the device and carefully check for faulty wiring. If it is
determined that the problem is caused by an electronic defect, the device must
be returned to the factory for repair.

LECTROSTATIC SENSITIVE DEVICE (ESD)
Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic
charge caused by direct contact 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
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
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
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
• Enure 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.
—ESD! If the charge is sufficient and
—performance may be marginal
—taking care not to touch electronic
A warning label is placed on the packaging, identifying product using
electrostatic sensitive semiconductor devices.
