Installation

2.2 Locate sensor

Prior to the installation process, develop a location plan for placing the Net Safety APM
Sensor and Transmitter. Proper location of the Net Safety APM Sensor is essential for
providing maximum protection. The most effective placement and number of detectors
varies depending upon conditions. Consider the following points when planning the
installation.

• Carefully locate the Net Safety APM Sensor in an area where particulate may

potentially accumulate.

• Locate the Net Safety APM Sensor where it is safe from potential sources of

contamination, such as oil film, dirt, etc.

• Locate the transmitter where it will be accessible and visible.

• Mount the Net Safety APM Sensor so air currents allow particulate to flow into the

optical path of the sensor.

• If the particulate is expected to be moving horizontally due to air currents, orient the

sensor for maximum detection as shown in Figure 2-1.

• Avoid exposure to excessive heat or vibration whenever possible, because this can

cause premature failure of electronic devices.

• Seek advice from experts and refer to various regulatory publications that discuss

general guidelines for your industry.

• The Net Safety APM works off of the principle of infrared energy being reflected off

of particulate matter passing through the optical path of the Net Safety APM.
Therefore, give careful consideration when installing the Net Safety APM to ensure
that external infrared light does not reach the sensing element.

Figure 2-2 illustrates a typical installation of a Net Safety APM Sensor and Transmitter. The

Net Safety APM Sensor is mounted separately from the transmitter using the supplied
junction box. The transmitter is located at eye level, while the sensor is located where
particles are most likely to accumulate. The conduit then connects the two devices.

Junction Box and Sensor DimensionsFigure 2-4:

6 Millennium Air Particle Monitor

2.4 Mount

The sensor must be mounted directly to either a transmitter or to a separate junction box
through a ¾ in. NPT conduit entry. Both the transmitter and junction boxes have mounting
holes to allow mounting to a wall or pole as desired. Mounting kit hardware is required
when mounting the transmitter or junction box to a pole. Contact your local Net Safety
representative for detailed information on the pole mounting kits.

Mount the transmitter at eye-level and make it easily accessible for monitoring and
maintenance purposes. Place the sensor where particles are likely to accumulate and
across the direction of the airflow to allow the particulates to pass through the optical
path. To prevent water damage, seal conduit at all points of entry to the transmitter or
junction box.

Emerson™ recommends mounting the Net Safety APM Sensor such that the air flow will
pass through the optical path of the sensor as shown in Figure 2-5.

Note

The Net Safety APM works off of the principle of infrared energy being reflected off of particulate
matter passing through the optical path of the Net Safety APM. Therefore, give careful consideration
when installing the APM to ensure that external infrared light does not reach the sensing element.

Installation

The Net Safety APM may be affected by sudden bursts of infrared light; therefore, Emerson
recommends putting a time delay (between two [2] and five [5] seconds) into the
monitoring system to prevent nuisance alarms.

Duct mount

Although the Net Safety Monitoring Air Particle Monitor has been proven to detect
particulate matter travelling at speeds of up to 20 meters per second (65.62 feet per
second), the detector is virtually unaffected by the velocity of particulate and air that it is
exposed to. Based on the application and the speed of the particulate matter, you can
perform a zero and adjust the sensitivity settings to suit the application.

Net Safety Monitoring recommends that the Net Safety APM be used with the UDM-001 or
UDM-002 sample draw system to acquire a cross-sectional sample of air and particulate
moving through ducts. The sample is drawn through perforations along the inlet pipe into
a chamber where the Net Safety APM is mounted. Particulate matter from the outlet pipe
is then returned to the duct. Refer to Figure 2-6 and the

UDM-001/UDM-002 reference manual (MAN-0116) for more information.

2.5.1 Field installation

WARNING!

ELECTRIC SHOCK
Failure to follow these installation guidelines could result in death or serious injury. Ensure that
only qualified personnel perform the installation.

Electrical shock could cause death or serious injury. Use extreme caution when making contact
with the leads and terminals.

Do not open the transmitter, sensor, or junction box enclosure when in a classified area or
when an explosive atmosphere may be present unless the power to the transmitter has been
removed.

Avoid touching electronic components as they are susceptible to electrostatic discharge (ESD).
Refer to Chapter 6 for more information.

Avoid contact with the non-metallic enclosure label as contact may create an electrostatic
charging hazard.

2.5.2

NOTICE

Wiring codes and regulations may vary. ATEX requires that supply connections wiring must be
rated at least 5 °C (41 °F) above the maximum ambient temperature of 85 °C (185 °F). Wiring
must comply with all applicable regulations relating to the installation of electrical equipment
in a hazardous area and is the installer's responsibility. If in doubt, consult a qualified official
before wiring the system.

When separating the sensor from the transmitter, Emerson highly recommends the use of
shielded cable to protect against interference caused by extraneous electrical or
electromagnetic noise to meet mandatory CE mark electromagnetic compatibility (EMC)
requirements. In applications where the wiring is installed in conduit, the conduit must not
be used for wiring to other equipment.

Seals

Emerson recommends using seals to further protect the system against any unwanted
water ingression and installing equipment according to applicable local electrical codes.
Emerson especially recommends seals for installations that use high-pressure or steam
cleaning devices in proximity to the transmitter and/or sensor.

• Emerson recommends water-proof and explosion-proof conduit seals to prevent

water accumulation within the enclosure.

• Locate seals 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.

10 Millennium Air Particle Monitor

• When pouring a seal, use a fiber dam to assure proper formation of the seal. Never

pour seals at temperatures below freezing.

• Strip back the jacket and shielding of the cable to permit the seal to form around the

individual wires. This will prevent air, particles, and water leakage through the inside
of the shield and into the enclosure.

• Emerson recommends using explosion-proof drains and conduit breathers. 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.

2.5.3 Sensor separation

Since the Net Safety APM Sensor must be located where it will pick up particulate in an air
flow, and the transmitter where it can be easily reached, it is often necessary to separate
the transmitter and sensor. This is done with the aid of the included sensor separation kit
(SEP). This kit is composed of a junction box and terminal strip. Refer to the

Net Safety Multi-purpose Junction Box manual (MAN-0081) for terminal designation.

The maximum separation distance between the sensor and the transmitter is limited by
the resistance of the connecting wiring, which is a function of the gauge of wire being
used. Net Safety recommends that sensor separation must not exceed 610 m (2,000 ft)
while using 16 AWG (1.31 mm2) wire. Refer to Chapter 7 for wire gauges and resistance
values.

Installation

2.5.4

Note

When the sensor is separated from the transmitter, always ensure that the transmitter is supplying
the required voltage to the sensor terminals inside the junction box. If the 4-20 mA signal is not used,
connect a jumper between the 4-20 terminal and the COM terminal on the transmitter terminal
board.

Board assembly

There are three different fixed boards and a relay board which make up the PCB assembly.
Simply loosen the three locking standoffs, remove one board, insert the other board, and
tighten screws. The boards are susceptible to electrostatic discharge (ESD). Refer to

Chapter 6 for further information on proper handling of this equipment.

2.5.5 Installation to transmitter or junction box

The Net Safety APM sensor is supplied with a ¾ in. NPT male conduit connection and is
intended to be mounted directly to an available ¾ in. NPT conduit entry on the Net Safety
Millennium Transmitter or remotely using the supplied junction box.

Tightly thread the sensor to the transmitter or junction box. A minimum of seven (7)
threads need to be engaged to ensure proper water ingress protection and the explosion
proof rating of the devices. Take proper care to ensure that no damage is caused to the
wires on the Net Safety APM Sensor and circuit board inside the transmitter and junction
box.

Emerson recommends using conductive grease on the threads.

The sensor can be mounted in a number of configurations to ensure that air particulate will
pass through the optical path of the sensor. Emerson recommends that the APM be
mounted horizontally to ensure that build-up of dirt, dust, and debris will not affect the
operation of the sensor.

12 Millennium Air Particle Monitor

2.5.6 Faceplate rotation

In some applications, it is necessary for the Net Safety Millennium Transmitter to be
mounted in a non-standard orientation. To accommodate such installations and ensure
that the display will appear at the correct angle for viewing, you can rotate the PCB
assembly inside the transmitter’s housing. Figure 2-8 outlines non-standard orientations of
the Net Safety Millennium Transmitter.

Operation

3.3.1 Net Safety APM fault

To ensure proper response, the Net Safety 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, the transmitter continuously monitors the signal from the
internal APM source. If the transmitter determines that the APM program is not running
correctly, it will reset the Net Safety APM Sensor.

3.3.2

Clean window/dirty chamber

Over an extended period, oily film or particulate build-up on the sensor window may
obscure the detector. When dirty, the Clean window alarm trips, the message Dirty

Chamber displays, the Status LED flashes fast red, and the current output is 3.3 mA. Refer
to Section 4.3.2 to define the clean window sensitivity and Section 5.2 on cleaning the Net

Safety APM window.

Reference Manual 25

Operation

3.3.3 Particulate alarm

When particulate is present in the Net Safety APM’s chamber, the message Alarm
displays, the Status LED blips red, and the current output is 20.0 mA. If the relay has been

set to non-latching, the unit resets itself; if set to latching, a manual or remote reset is
required to clear the alarm condition. Refer to Section 3.4.

Note

The Net Safety APM may be affected by sudden bursts of infrared light; therefore, Emerson
recommends that a time delay [between two (2) and five (5) seconds] be put into the monitoring
system to prevent nuisance alarms.

3.4 Reset

3.4.1 Remote reset

The Net Safety Millennium is capable of remote reset. A normally open push-button switch
must be connected between the RST terminal and the COM terminal on the terminal
board. If relay is set to Latching, a remote reset is possible.

3.4.2 Manual reset

If a relay is set to Latching, a manual reset is required to clear the alarm condition. Simply
place and hold the magnet against the Reed switch or press and hold Setup for 3-5
seconds. The unit returns to normal operation.

3.6

Normal

With no particulate present and no fault detected, the display reads Clear, Status LED
blips/blinks green, and the current output is 4.0 mA.

Outputs

3.6.1 Relays

All relay outputs have FORM-C SPDT contacts rated 5 amperes at 30 Vdc/250 Vac. Relays
are dry contacts.

26 Millennium Air Particle Monitor

3.6.2 Current

A 4-20 mA dc current output is used to transmit the alarm status and fault conditions to
other devices. This output can be wired for isolated or non-isolated operation. A 4.0 mA
output indicates normal operation; a 20.0 mA output indicates that the alarm threshold
has been exceeded. Current output of 2.5 mA indicates the presence of a system fault.
Current output of 3.3 mA indicates a build-up of particulate in the sensor’s chamber or
dirty window. Refer to Section 3.2 for additional indications and outputs.

3.7 Net Safety APM Sensor

3.7.1 Sensor power up

When the transmitter applies power to the sensor, a warm-up routine begins, and the
sensor is automatically tested to ensure proper functioning. The warm-up time for the Net
Safety APM Sensor is typically one hundred fifty (150) seconds. After the warm-up cycle
has completed, the display reads Clear.

Operation

3.7.2

As part of the self-diagnostic routine of the Net Safety Millennium Transmitter, the analog
output outputs 20 mA on initial power up for a period not greater than 450 milliseconds. If
routine power loss is expected on the system, take appropriate actions to limit false alarm
conditions due to this diagnostic routine.

6 Electrostatic sensitive device

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. 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 the sides — taking care not to touch electronic components.

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

unwanted static energy.

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

grounded metal surface.

• Ensure all components are transported and stored in ESD 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.

• Clean off the housing with a damp cloth only.

Electrostatic sensitive device

In general, exercise accepted and proven precautions normally observed when handling
electrostatic sensitive devices.
