INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD PEM MANUAL – PARTICULATE EMISSION MONITOR
This chapter provides information on unpacking, installing, and setting up the instrument. It also includes information on
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 standards
D
and
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).
D
The definitive guide for isokinetic sampling port location is given in standards ISO 9096 and EN 13284-1.
