requirements and safety guidelines.
5.1 UNPACKING AND STORAGE
Remove all transit packaging. Inspect the sensor for signs of damage. If it is damaged, contact Goyen | Mecair immediately.
If the equipment is to be stored prior to installation, then repack it in the original transit packaging and store in a dry
environment.
No responsibility for damage arising from the use of non-approved packaging will be accepted.
NOTE: Ensure all items and accessories specified are present. If not, contact Goyen | Mecair or our local representative.
5.2 PREREQUISITES AND GUIDELINES
5.2.1 Safety Information
WARNING! – DANGER FROM PROCESS
It is possible that the sensors are to be installed in ducting containing process particulate that is
a hazard to health.
Unless the process conditions are known to be entirely safe, suitable precautions such as the use of
breathing apparatus or duct purging/detoxifying must be employed before any entry is made into the duct
for installation or maintenance purposes. If in doubt, consult your local Safety Officer and/or local safety
procedures.
WARNING! – ELECTRIC SHOCK
A suitable approved and rated two-pole mains isolation device must be clearly marked and installed
close to the sensor unit (within a 2 m/6½ ft radius) and readily accessible.
WARNING! – ELECTRIC SHOCK
(1) Ensure that only suitable and rated cables types are used for power supply and interconnection of
equipment.
(2) When wiring the mains cable, ensure that the Protective Earth wire (GND) is the longest one, so that
if the cable is pulled out accidentally, the earth wire disconnects last.
5.2.2 Choosing the Best Position for the Sensor
When selecting a mounting location for the sensor, the following guidelines are based on the related standardsDand
should be taken into consideration to ensure optimum performance of the instrument, safety, and for compliance
purposes.
The best position for the sensor unit is in a section of ductwork where the particulate has an even distribution and
the flow is linear. This would ideally be in a vertical or horizontal section of duct that has no bends or obstructions
for at least three duct diameters downstream or upstream. In many applications, a compromise must be made, but
the sensor should be fitted in a position that satisfies the majority of the below requirements.
NOTE: The sensor must be fitted to metal ductwork in order to be electrically screened from interference signals
(see Grounding the Sensor on the next page).
DThe definitive guide for isokinetic sampling port location is given in standards ISO 9096 and EN 13284-1.
5 SENSOR INSTALLATION

10 INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD PEM MANUAL – PARTICULATE EMISSION MONITOR
5.2.3 Location Requirements
When selecting a mounting location for the sensor the following should be taken into consideration for optimum
performance:
• In the longest, straightest, unrestricted section of ductwork available.
• In metallic ductwork (for non-metallic ductwork contact Goyen | Mecair).
• Away from ambient or radiated temperatures greater than +50°C (120°F).
• Where possible, the equipment should be mounted out of direct sunlight, precipitation, and away from running
water.
• Hazardous Zones: refer to the Sensor Safety Description on page 4 for details of ATEX-related special conditions
and requirements.
5.2.4 Cabling Guidelines
Cables should be fixed such that they are free from excessive vibration and not under strain. Cables should
be secured in accordance with good engineering practice (e.g. using cable trays where possible) and careful
consideration should be given to the positioning of cables so that they are not damaged easily. Cables should
be routed to avoid sources of large electromagnetic fields, such as heavy switching gear. Care taken during the
installation of the cables ensures a long, maintenance-free life and avoids possible damage to the control unit
and sensor.
In summary, the cabling should be installed such that:
• Heavy vibration is minimized to prevent fatigue and failure.
• It is not vulnerable to accidental damage.
• It is away from sources of large electromagnetic fields (if possible).
5.2.5 Grounding the Sensor
For PEM sensors it is essential that the sensor body is grounded to the stack wall. This is necessary for Ex safety.
In addition, poorly grounded sensors may pick up external noise producing false high readings.
Ensure the installation complies with the following:
• The sensor may only be fitted to a metal duct or stack, if the stack is not metallic or you are concerned that the
stack may not provide a suitably earthed shield for the sensor, please contact Goyen | Mecair.
• The grounding strap (or earth wire) provided may be connected to ensure the sensor body is securely grounded
to the metallic stack wall. The sensor is electrically grounded to the ductwork by the mechanical connection made
between the sensor and the socket, and by the external grounding strap.
NOTE: The grounding strap must be connected between sensor enclosure and stack wall. Relying on the stack
connection only is not acceptable in hazardous areas!
• When connecting the grounding strap between sensor enclosure and stack wall leave sufficient length so that the
sensor can be removed and placed on the ground or platform for maintenance without disconnecting.
• For threaded connections: Do NOT put PTFE tape around the thread (as this can compromise the sensor grounding
connection)!
• If necessary, remove excessive rust from the thread and socket and apply a copper-loaded grease.
5.2.6 Running Cables between Sensor and Power Supply
CAUTION!
Do NOT route cables where they may be at risk from lightning damage (e.g. over exposed roofs).
• To prevent water from entering the instrument, mount all instruments and accessories with the cable entry
glands facing downward.
• After inserting and connecting a cable, fasten the cable glands tightly onto the cable to form a seal. Leave a little
slack in the cores.
• Cable sheathing must always penetrate the cable entry gland fully, and the gland must be fastened tightly to it.
• Where a cable run approaches the instrument from above, it must be run underneath the instrument and then
curved up to the cable gland.
• Leave sufficient slack in the cable to allow the sensor unit to be removed and placed on the ground/platform
for servicing.

11INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD PEM MANUAL – PARTICULATE EMISSION MONITOR
• Support cables at appropriate intervals. Where possible, use cable trays.
NOTE: For EMC reasons (interference rejection and surge handling), all of the cable trays carrying signal cables
should be electrically continuous (i.e. the sections should be interconnected by heavy-gauge electrical
wiring) and they should be connected to Earth at multiple points along their length. Cable trays are
typically secured to grounded metal structures, which satisfies this requirement.
• The cable screen must be terminated correctly.
• Any unused cable glands must be blanked using an appropriate device.
• When connecting the sensor, the 4 off screws securing the enclosure cover lid should be coated with a small
amount of copper grease before refitting and securing the lid. Do not over-tighten the screws.
5.3 MOUNTING THE SENSOR
5.3.1 Safety Information
CAUTION! – PROBE DAMAGE
Take care when handling the sensor to avoid bending or damaging the probe. Probe damage may result
in inaccurate measurements.
CAUTION!
Do NOT try to rotate the sensor by turning its enclosure as this can damage the sensor.
5.3.2 Fitting the Sensor to the Stack

12 INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD PEM MANUAL – PARTICULATE EMISSION MONITOR
1. Drill a hole with an ID of at least ∅ 45 mm in the stack/duct where the sensor is to be located.
2. Fit a 1.5″BSP socket, which must be securely welded to the stack. Ensure the BSP socket is 90° to the stack or
at a slight upward angle of about 5°, so the sensor probe points downwards allowing condensate to drain off into
the stack.
3. Insert the sensor probe into the socket and secure with the floating nut. Ensure the sensor enclosure is upright
with the cable entry glands at the bottom and is adequately supported when tightening the floating nut.
NOTE: Ensure the grounding strap connects the sensor securely to the stack/duct via the earth stud assembly
at the rear of the sensor enclosure.
4. Tighten the lock nut. When tightening the lock nut ensure the floating nut is held securely with a wrench.

5.4.2 Connecting the Sensor Power Supply
WARNING!
Ensure the cabling is not connected to control unit power during wiring.
WARNING! – ELECTRIC SHOCK
This equipment contains lethal voltages!
Do not reverse Live (L) and Neutral (N) – the neutral line is not fused!
Hazardous voltages are still present when the main power supply fuse has failed!
The label on the PSU cover and the markings on the power connector indicate the voltage required.
Connect only to a power supply with a voltage corresponding to that on the rating plate.
Connecting the Cables
Easily accessible disconnect devices, such as switches or circuit breakers along with a separate fuse, must be
fitted to the power supply wiring for mains-powered sensors. These must be located so they can be reached easily
(within a 2 m/6½ ft radius of the unit). The isolation devices should connect/disconnect both mains Live (L) and mains
Neutral (N) and must be clearly marked as the disconnecting device for the instrument.
5.4.3 Wiring the Mains Power Supply
1. Undo the 4 off screws and open the hinged sensor enclosure lid.
2. Note the label on the power supply/PSU cover (see Figure 3 below).
3. Referring to Figure 4 on the next page, undo the 2 off screws and remove the PSU cover.
4. Route the power supply cable through the right-hand cable gland and connect to the mains power terminals as
outlined in the following table.
