06 INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD FFA MANUAL – FILTER FAILURE ALARM
3.2 OVERVIEW
The Filter Failure Alarm Monitor (FFA) is suitable for use after bag filters, cartridge filters, cyclones, and a range of other
applications to ensure correct, expected filter performance. The FFA system comprises a sensor and a dedicated control
unit. The sensor is suitable for use in processes of up to 240°C (465°F).
The control unit can be located remotely (maximum distance: 300 m/985 ft).
NOTE: All system components (except the sensor) must be placed in the designated Safe Area (refer to the Functional
Diagram on page 7).
3.2.1 Sensor
The sensor benefits from unique Probe Electrification technology. It comprises a metal probe rod that protrudes into
the stack and connects to the stack via the hexagonal body connected to the sensor enclosure, which contains the
advanced electronics module. The sensor is fitted to the stack using a ½″socket and thread and secured in position
with a lock nut.
Adjustable Alarm Levels
Dual alarming enables operators to configure early warning and limit (high) alarm levels providing flexible sensitivity
to suit the process. The internal setting can be adjusted to avoid triggering false alarms due to temporary spikes,
e.g. during bag-filter cleaning cycles.
3.2.2 Control Unit
The control unit contains the power supply, alarm connections, and has easy-to-use user controls. The control
unit contains the alarm relays, it provides the power for the sensor display and the user controls, allowing the
FFA system to be set up quickly.
The instrument provides a 4–20 mA output scaled to 0–100% of the limit alarm level, thus supporting the integration
of the instrument with external equipment.
3.3 PRINCIPLE OF OPERATION
The FFA sensor utilizes Probe Electrification measurement technology. The sensor measures the interaction between the
particulate in the air stream and the sensing rod to induce a charge signature. It extracts a specific frequency band and
filters out the DC current. The technology outperforms conventional DC tribo-electric systems by extending the range
over which the instrument has minimal cross-sensitivity to changing velocity while remaining unaffected by the build-up
of particulate on the sensing rod, thereby minimizing signal drift and providing reliable results and response.

07INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD FFA MANUAL – FILTER FAILURE ALARM
4.1 HAZARDOUS ZONES
The sensor may be installed in a metal stack or duct containing hazardous dust, but the control unit must be installed
in the designated Safe Area (see the Functional Diagram below). The control unit contains the power supply, alarm
connections, and user controls. The sensor unit is mounted to the ductwork such that the metal probe rod protrudes
into the flow of the particulate to be monitored.
4.1.1 Hazardous Zone Classification
The instrument is suitable for use in the following Ex zones:
INSIDE STACK OUTSIDE STACK
Gas zone Zone 2 Zone 2
Dust zone Zone 22 Zone 22
4.1.2 Functional Diagram

08 INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD FFA MANUAL – FILTER FAILURE ALARM
4.2 SPECIAL CONDITIONS OF SAFE USE
4.2.1 Special Conditions of Safe Use for Sensor Enclosure, Body and Probe
a) All connections to the equipment must not be inserted or removed unless the area in which the equipment
is installed is known to be non-hazardous, or the circuit to which it is connected has been de-energized.
This includes the plugging/unplugging of the screw terminals from the PCB-mounted headers.
b) A connection shall be made between the stud on the probe electronics housing and the duct wall. The connection
shall be made as follows:
• The cable shall have a cross-sectional area of at least 4 mm².
• The cable shall be connected using an anti-vibration nut and washer or a similar arrangement of comparable
integrity.
If the probe is removed while a potentially flammable dust or gas is present, this connection shall be maintained during
the withdrawal of the probe.
c) The part of the equipment that houses the electronics is suitable for an ambient temperature of –20°C to +50°C
and the standard range of atmospheric pressure; the user/installer shall ensure that the process temperatures
and pressures, including within the dust stack, do not cause these parameters to be exceeded.
d) If the equipment is likely to come into contact with aggressive substances (e.g. Acidic liquids or gases that may
attack metals or solvents that may attack polymeric materials relied upon for sealing), then it is the responsibility
of the user to take suitable precautions that prevent it from being adversely affected, thus ensuring that the type
of protection (Non-sparking device Ex nA for sensor enclosure, body and probe, and additionally Dust exclusion
Ex tc for the sensor body and probe) is not compromised.
e) Cable Glands and Stopping Plugs certified to EN 60079-0 (e.g. Dust-protected, ta/tb/tc; Increased safety, Ex e;
Flameproof, Ex d; Type of protection “n” Ex n) are acceptable, provided they are fitted with the appropriate seal
to the enclosure and maintain a minimum ingress protection of IP64. (This seal may be incorporated within the
gland or plug.)
f) Under certain extreme circumstances, the non-metallic labels and insulating bush may store an ignition-capable
level of electrostatic charge. Therefore, the electronics enclosure shall not be installed in a location where the
external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the
non-metallic parts shall only be cleaned with a damp cloth.
f) The equipment must be powered from a nominal 24 V DC power supply that includes transient protection at no
more than 119 V DC. This requirement will be met if the power supply meets the requirements of the Low Voltage
Directive.
4.2.2 Additional Special Conditions of Safe Use for Sensor Body and Probe
a) The ½″Sensor Body must be mounted in the dust stack so that the PTFE insulator is positioned within the wall of
the dust stack, to protect the insulator from a build-up of electrostatic charge and to protect it from any possible
impact.
b) The ambient temperature range within the dust stack in which the ½″Sensor Body and Probe are mounted must
be no more than –20°C to +240°C.

6.2 PREREQUISITES AND GUIDELINES
6.2.1 Choosing the Best Position for the Sensor
When selecting a mounting location for the sensor, the following guidelines are based on the related standardsCand
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 Connecting the Sensor on page 18 below for information on running the cables between the sensor and
control unit (signal cable and parallel earth cable).or below).
6.2.2 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 7 for details of ATEX-related special conditions
and requirements.
6.2.3 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.
CThe definitive guide for isokinetic sampling port location is given in standards ISO 9096 and EN 13284-1.
