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 sensor is essential for providing maximum
protection. The most effective placement and number of detectors vary depending upon
conditions. Consider the following points when planning the installation.

• Carefully locate the sensor in an area where particulate may potentially accumulate.

• Locate the 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 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 detector works off of the principle of infrared energy being reflected off of

particulate matter passing through the optical path of the detector. Therefore, give
careful consideration when installing the detector 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

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.

A. Bracket mounting holes (four places)

2.4 Mount

The sensor must be mounted directly to either a transmitter or to a separate junction box
through a ¾-in. national pipe thread (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 sensor such that the air flow will pass through the
optical path of the sensor as shown in Figure 2-5.

Reference Manual

00809-0100-4077 September 2019

Note

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

Sudden bursts of infrared light may affect the detector; therefore, Emerson recommends
putting a time delay (between two and five seconds) into the monitoring system to
prevent nuisance alarms.

Duct mount

Although the Net Safety™ Monitoring APM has been proven to detect particulate matter
travelling at speeds of up to 65.62 feet per second (20 meters 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 recommends using the detector with the UDM-001 or UDM-002 sample draw
system to acquire a cross-sectional sample of air and particulate moving through ducts.

Install Reference Manual

September 2019 00809-0100-4077

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 Wire

2.5.1 Install in field

WARNING

Electrical shock

Electrical shock could cause death or serious injry

Ensure that only qualified personnel perform the installation.
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 where 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 Electrostatic sensitive device 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 above the maximum ambient temperature of 185 °F (85 °C).
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, do not use the
conduit 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 in. (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 fiber dam to assure proper formation of the seal. Never

pour seals at temperatures below freezing.

Net Safety Millennium Air Particle Monitor 15

Install Reference Manual

September 2019 00809-0100-4077

• 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 Separate sensor and transmitter

Since the sensor must be located where it will pick up particulate in an air flow and the
transmitter must be where it is easily reached, you may have to separate the transmitter
and sensor. Do this 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 2,000 ft. (610 m)
while using 16 AWG (1.31 mm2) wire. Refer to Wire resistance table for wire gauges and
resistance values.

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 you are
not using a 4-20 mA signal, connect a jumper between the 4-20 terminal and the COM
terminal on the transmitter terminal board.

Assemble boards

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

Electrostatic sensitive device for further information on proper handling of this

equipment.

2.5.5 Install to transmitter or junction box

The sensor is supplied with a ¾-in. national pipe thread (NPT) male conduit connection
and is intended to be mounted directly to an available ¾-in. NPT conduit entry on the
transmitter or remotely using the supplied junction box.

Tightly thread the sensor to the transmitter or junction box. Engage a minimum of seven
threads 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 sensor
and circuit board inside the transmitter and junction box.

Emerson recommends using conductive grease on the threads.

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

2.5.6

Rotate faceplate

In some applications, you may need to mount the transmitter 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 transmitter.

3.3.1 Transmitter fault

To ensure proper response, the transmitter 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 Net Safety™ APM source. If the transmitter determines that the Net Safety APM
program is not running correctly, it will reset the 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 Set sensitivity to define the clean window sensitivity and Clean sensor for
instructions on cleaning the Net Safety APM window.

Net Safety Millennium Air Particle Monitor 31

Operation Reference Manual

September 2019 00809-0100-4077

3.3.3 Particulate alarm

When particulate is present in the detector'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 Reset.

Note

Sudden bursts of infrared light may affect the detector; therefore, Emerson recommends
that a time delay (between two and five seconds) be put into the monitoring system to
prevent nuisance alarms.

3.4 Reset

3.4.1 Remote reset

The detector 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
three to five seconds. The detector returns to normal operation.

3.5 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.

3.6 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.

32 Emerson.com/Rosemount

Reference Manual Operation

00809-0100-4077 September 2019

3.6.2 Current

The detector uses a 4-20 mA dc current output to transmit the alarm status and fault
conditions to other devices.

You can wire this output 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 Indications and outputs for additional indications and outputs.

3.7 Sensor

3.7.1 Power up sensor

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 sensor is typically 150 seconds. After the warm-up cycle has
completed, the display reads Clear.

3.7.2

As part of the self-diagnostic routine of the 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.

Sensor communication

The Net Safety APM sensor uses a proprietary protocol to communicate with the Net
Safety Millennium transmitter.

Never connect the Net Safety APM sensor to any device other than a Net Safety
Millennium transmitter. If any problems develop, please refer to Troubleshooting.

5.1 Check response

Emerson recommends checking and testing the Net Safety™ APM at least once every three
months.

Procedure

1. Spray Smoke Detector Tester (or equivalent product) in the direction of the sensor.

CAUTION

Equipment damage

Overusing artificial particulate detector testers or spraying from too close a range
may cause an oily film to accumulate on the internal window, impairing the
operation of the detector.

Stand at least 2 ft. (0.6 m) away from the sensor when spraying the tester.

Typically, a one to two second burst is adequate to initiate an alarm.
When the alarm activates, the display reads Alarm, the Status LED flashes red, and

the current output is 20.0 mA to indicate detection of particulate matter or canned
contaminant.

2. After simulation, reset the alarm if latched as outlined in Reset and zero the Net
Safety Air Particle Monitor as per Zero transmitter in clean air free of particulates or
at the accepted particulate background level for the specific application.

5.2 Clean sensor

Clean the sensor routinely. The frequency of cleaning depends on the application and
environment where the sensor is installed.

Reference Manual Electrostatic sensitive device

00809-0100-4077 September 2019

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.

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