4.9 - The detector is equipped with ATEX marking
CE 0722 II 2GD Ex db op is IIC T6 Gb
Ex tb IIIC T85 ° C Db
therefore the appliance can be installed in environments with an explosion hazard (gas and dust) zones: 1 - 2 - 21 - 22
5- VALIDITY
5.1-Theseinstructionsarevalidfor the FL-50 flamedetector, when used inareas with potentially explosive atmospheres
according to the ATEX 2014/34 / UE directive
6- OPERATION
6.1 - The FL-50 flame detector is able to detect a flame produced by a fire within its field of vision within a few seconds.
The FL-50 detector reacts with great sensitivity to the emission of infrared IR and ultraviolet UV radiation emitted by a
source of adequate power in its field of vision. However, the emission of IR or UV radiation alone is not sufficient to cause
the alarm. It is in fact necessary that the emission includes both radiations, such as those produced by the flame.
FL-50 is also equipped with special and sophisticated algorithms that analyze the spectrum, the frequency, the intensity and
the duration of the radiation. Only when signals are present that fall within the calibration parameters, the alarm is generated.
This makes the detector highly immune to false alarms.
7- PRECAUTIONS BEFORE INSTALLATION
7.1 -All installation and maintenance operations must be carried out when the device is not live
7.2 - When the cover is opened, great care must be taken not to damage the O-ring type gasket
7.3 - To avoid damaging the cover-bottom coupling, carefully clean the surfaces before coupling them
8- IMPORTANT INSTALLATION RULES
8.1 - Prevent the detector from being exposed to direct sunlight.
The sun is a powerful source of IR and UV radiation.
If this source is modulated by some elements, such as curtains moved by the wind in front of a window, it can cause false alarms.
Therefore outdoor installation must be carried out after careful examination of the environmental conditions and possibly using the
lowest sensitivity levels and the longest intervention delay. The use of the FL50-PSLsunshade is recommended.
8.2 - The positioning of the FL-50 detector must be carried out so as to allow future maintenance operations in an easy and
accessible way.
8.3 - The installation must be so that the detector is not subjected to vibrations and possible shocks.
8.4 - If the FL-50 detector is installed in dirty and dusty places, a periodic verification of the detector operation and a frequent
cleaning of the optical windows is required (chap.13)
8.5 - Prevent the angle of vision of the detector from being obscured by obstacles (shelves, packages, pallets, etc.)
8.6 - Avoid large detector temperature changes.

EDS - INFORMAZIONI TECNICHE
5
The detector must not be installed near heat or cooling sources. The generation of ice or moisture inside or outside the
detector can compromise its functionality. In the presence of such problems, it is useful to use the version of FL-50
equipped with an automatic temperature control system (see detector code). This system keeps the optical windows at
a suitable temperature to obtain regular functionality.
8.7 - Prevent the detector from having a direct view of IR and UV sources that could be modulated by certain environmental
conditions. The presence in the viewing angle of electric arcs produced by welding machines, industrial lighting systems,
gamma rays, etc. can sometimes disrupt the detector's operations. Keep in mind that, to generate an alarm, these
perturbations must persist for a time longer than the time delay programmed on the detector.
Therefore, if the disturbing source acts for a shorter time, no alarm will be generated.
9- INSTALLATION
9.1 - The appliance must be installed on the ceiling or on the wall.
In general, the ceiling position is recommended for the monitoring of materials laid on the floor. In this case, to prevent
the smoke from a hatching fire from obscuring and therefore reducing its sensitivity, we recommend installing the detector
at 1-1.5m from the ceiling.
By loosening the GH ring (fig.8) of the brackets it is possible to orient the appliance in various directions.
9.2 - If several detectors are used in the same environment, avoid having two detectors pointed towards each other.
9.3 - The installation height is in relation to the area to be controlled, bearing in mind that the viewing angle of the detector
is 100 ° C and that its maximum flame detection distance (with a target generated by a flame reference from petrol with
a height of 20 cm within a 33x33x5 cm tray) is 50 m. The graph in fig.4 indicates the protected area as a function of
distance and sensitivity. The sensitivity of the detector is dependent on the flame generated by various liquids and
combustible gases.
In the table of fig. 1 the detection distances according to the flame generated by various elements are listed.
9.4 - To install the cables, 1 or 2 threaded holes 1/2 "NPT - 1/2" GK - M20x1.5 are provided.
The product is supplied without cable gland . It must be the customer's responsibility to use ATEX certified cable
glands in accordance with current plant regulations EN60079-0; EN60079-1; 60079-31 - IP65 protection degree.
We recommend to use the cable gland EDS type PSC-12-EMI for maximum protection against electromagnetic
interference.
9.5 - Open the front cover by loosening the 4 hexagonal head screws and access the terminal board.
Connect the terminals with a fire-resistant multipolar shielded cable according to local standard with adequate insulation
and mechanical resistance (eg. FG7) according to the diagram in fig. 6.
The section of the 2 power supply wires must be at least 1,5 mmq for 500m distance.
The conductors for the other signals (relays, analogue output, etc.) may have a lower section.
Ifyou use the EDS PSC-12-EMI cable gland, the shields ofthe cable must beinstalled as shown in the following figure.

10 - SETTINGS
FL-50 can be configured for specific environmental needs (Ta = -20 / + 55 ° C) through a suitable selection of sensitivity
and time delay for the IR and UV sections. Therefore, after careful examination of the environmental characteristics, the
installer has the possibility of setting the detector to obtain the best performance.
10.1 - Setting the relays
Alarm Relay. Supplied normally de-energized. The JP1 jumper (see fig.9) allows, depending on the position, operation
with relay normally energized or not energized. Therefore:
position 1-2 normally excited
position 2-3 normally not excited‘
Fault Relay. Supplied normally de-energized. The JP2 jumper (see fig.9) allows, depending on the position, operation
with relay normally energized or not energized. Therefore:
position 1-2 normally excited
position 2-3 normally not excited
After selection use the correct NC - NA position of the relays.
10.2 - Sensitivity adjustment
The FL-50 detector has two independent adjustment possibilities for the IR and UV section:
IR - 4 sensitivity levels using the Dip_Switch S3 (high - medium / high - medium / low - low) - fig. 9 and tab.fig.2
UV - 4 sensitivity levels using the Dip_Switch S2 (high - medium / high - medium / low - low) - fig. 10 and tab. fig.3
10.3 - Delay of intervention
FL-50 has 4 delay levels for the activation of the alarm relay, which can be selected with the S2 Dip-Switch (fig.10 - fig.3)
• 5 seconds
• 10 seconds
• 20 seconds
• 30 seconds
If the radiation source acts continuously, raising both IR and UV detectors, an alarm signal is generated for a longer time
than the programmed one.
The times indicated above can vary up to 5-30% depending on the programmed sensitivity.
10.4 - Alarm Memory
The alarm memory can be activated via the S2 Dip-Switch (fig. 10 - fig.3). In the event of an alarm the detector remains
in alarm until the power supply is interrupted for at least 5 seconds.
10.5 - Setting the optics heating system (if present in the model)

EDS - INFORMAZIONI TECNICHE
8
FL-50 is supplied with the heating system set for the 24Vdc power supply. If the detector is powered at 12Vdc, the
heating system must be set for 12Vdc using the Dip-Switch S1 (fig.10).
The table in fig.4 indicates the settings for the 12 and 24Vdc voltages.
The automatic heating system intervenes if the room temperature drops below 5 ° C.Above 5 ° C the system is deactivated.
11 - VERIFICATION OF OPERATION
After installation, after the configuration operations and after completely closing the box, it is possible to power the detector
and proceed to check the operation.
11.1 - If false alarms are generated, it must be checked whether disturbing elements exist in the area controlled by the
detector. If necessary, change the sensitivity and time delay settings to compensate for these anomalies.
11.2 - LED indications
When the detector switches on, the White, Red and Yellow LEDs flash three times.
White LED
- flashing every 10 seconds - indicates normal operation
- steady light - when both the IR and UV sections are both activated due to the presence of a flame, a pre-alarm indication
is immediately generated by permanent switching on of the white LED (walk test / preallarm).
Red LED
- steady light - when the detector detects the IR + UV radiation of the flame for a time longer than the programmed time
delay on the detector, the red LED lights up to indicate the alarm condition
Yellow LED
- steady light - indicates the Fault condition during manual or automatic Test
11.3 - If possible, perform a function test as described in point 12.1.
12 - MANUAL AND AUTOMATIC TEST (if present in the model)
The FL-50 detector can be equipped as an option with a Manual and Automatic Test system for checking the operation
of the IR and UV sensors and cleaning the optical windows. The Test consists in activating 1 IR source and 1 UV source
insidethe FL-50 . Activation is activated periodically automatically by the internal electronics or by pressing on a remote
buttoninstalledoutsidethepotentially explosive areaor insidethe explosivezoneprovided itisin explosion-proofexecution
withcharacteristicssuitable for installation in thisarea, connected as indicated intheinstruction manual.
12.1 - Manual Test
Warning! - This test, if successful, causes a true Alarm signal (Alarm output relay is energized and the analogue output
goes to 5V (or 20mA ).
Before performing this Test it is necessary to consider the consequences derived from the detector alarm.
Thereforeitis advisable to block the peripherals(sirens,extinguishing systems, etc.) connected to the detectoralarmrelay
toavoid damage. To allow manualtesting,theMTEST terminal must beconnectedtoan external Normally OpenNOpush-
button (NA). The push-button poles must be connected to the MTEST terminal and the other pole to the detector power
supplynegative. To execute the Manual Test,press the button for about1 second. The detector performs aseries of checks

EDS - INFORMAZIONI TECNICHE
9
and performs the activation of IR and UV signals to simulate the flame for a duration of about 120 seconds.
After this time the detector must go to Alarm and the analogue output (OUT) must indicate 5V (or 20mA).
Ifthe Test has a negativeresult the Fault relay is de-energized(if normally energized) and theanalogue output (OUT) will
indicate 0 V.
12.2 - Automatic Test
The FL50 detector periodically performs an Automatic Test every 24 hours.
If the Automatic Test is successful, no output signal is generated.
If the Test has a negative result no Alarm signal is generated but a Fault signal is generated.
This signal remains active until the cause of the Fault is eliminated
During the Test the detector generates an IR signal and a UV signal that simulate the flame to verify the correct response
of the sensors and associated electronics.
The test lasts about 120 seconds.
During the Automatic Test, the Alarm output relay and the analogue output remain blocked.
13 - FUNCTIONAL TESTING WITH TEST LAMP
For operational testing in the field of flame detectors EDS with infrared sensors IR and ultraviolet UV, we recommend the use
of the FLT-20 Portable Test Lamp. This instrument is suited for testing flame detectors installed in explosion-proof environments
with risk of explosion. In these environments, the flame detectors can not be tested with the use of flames or similar devices.
FLT-20 is explosion-proof Ex-d IIC T6 ATEX certified and therefore can be used in potentially explosive environments classified
as Zone 1 - 2 - 20 -21 - 22.
It should be remembered that in environments with danger of explosion it is absolutely not necessary to carry
out a functional test by lighting a flame.
14 - MAINTENANCE
14.1 - The detector's optical windows must be periodically cleaned to ensure regular operation. The frequency of this
operation must depend on the environmental characteristics. Use an antistatic cloth or a damp cloth to remove the dust.
Use a cloth dampened with slightly soapy water to remove any deposits.
