TYPE 95 Series 4
Integrated Flame
Scanner
SIL3
DESCRIPTION
The Fireye InSight Series 4 scanner belongs to an established family of versatile fully microprocessor based,
integrated flame scanners. The InSight Series 4 scanner holds multiple worldwide safety agency approvals (see
Model Listings for full details).
The InSight Series 4 scanners utilize advanced techniques for discrimination and integrate the flame detection,
amplification, safety determination and flame switch functions into a single detection head. No separate amplifier or
flame switch module is therefore required to interface with the main burner management system.
InSight Series 4 incorporates the superior detection and discrimination elements of the popular InSight II product
with some enhanced features.
The scanner measures the amplitude of the modulations (the flame “flicker”) that occur within the targeted flame.
During the scanner set-up procedure, the modulation frequency that yields the best flame ON/OFF discrimination is
selected. The appropriate modulation frequency and sensor gain can be either manually or automatically selected.
InSight Series 4 is a solid state detector scanner utilizing either UV or IR detector, and two different available
connectors which are compatible either with the 59-608, 59-547 and 59-497 (-1WINC models) cable.
Standard features include an independently adjustable Flame Relay, 21 choices of modulation frequency, adjustable
sensor gain, adjustable flame relay ON/OFF thresholds, a 4-20 mA analog signal strength output, Fault Relay, four
selectable programmable files (e.g. for different fuels or firing rates), and Auto Config capability with manual
override. Remote communication capability is available via optional “Fireye Explorer” PC software (CU-109).
These InSight Series 4 sensors have a two-line by sixteen-character alpha-numeric OLED display with a five-
pushbutton keypad.
The -2 models of the InSight Series 4 (e.g., 95UVS4-2, 95IRS4-2) provide a Form C flame relay output contact
(NO/NC).

All scanner models are powered by 24 Vdc, and contain electronic self-checking (no mechanical
shutter required). Electrical connection is via quick-disconnects or hard wired to terminal blocks on the explosion
proof models (e.g., 95UVS4-1CEX). Fiber optics are also available for extended viewing applications.
Type 95UVS4-1WINC is the UV model and is provided with a cable quick-disconnects compatible with the 59-
608 (Insight 1 cable 59-497). Type 95UVS4-1 has an InSight II style quick disconnect compatible with the 59-547
cable. The same IR models are 95IRS4-1WINC and 95IRS4-1.

OPERATION
The InSight Series 4 scanner has numerous adjustment options available. It can be tuned either automatically
or manually to achieve the optimum level of sensitivity to the target flame balanced with superior discrimination
of background radiation.
The InSight Series 4 scanner measures the amplitude of the modulations (the flame “flicker”) that occur within
the targeted flame. The sensor within the scanner measures these amplitudes seen within either the ultraviolet
(UVS4) or infrared (IRS4) spectral ranges across a wide range of flicker frequency bands. In addition, the scanner
has a flame relay (FR) that can be related to the sensor signals in logical configurations.
During the scanner set up procedure, the logical operation for the flame relay is selectedbasedonthesettingsrelative
to user gain, required (flicker) frequency band and switching thresholds. Refer to commissioning procedure for more
details on set up procedures, which is selected for the desired sensor.
The current Flame Signal Strength (FS) can be viewed on the scanner display via the main menu. This displayed
value is the measure of amplitude within the selected modulation (flicker) frequency band, for example: FS=185
(Flame signal for sensors rangesfrom 0 to 999)
The scanner set-up procedure, the operation and settingsrelative to the sensor signal and the flame relay is chosen
either in Auto Config or Manual Config mode to provide the optimum flame ON/OFF discrimination.
The flame relay FR energizes its normally open contacts closed when the flame quality is at or above the
programmed flame ON threshold and remains on until the flame quality is at or below the programmed flame
OFF threshold.
IMPORTANT NOTE - The FAULT RELAY is energized when the scanner is powered (24 V DC) and when the
scanner has successfully passed all internal self-checking routines. The Fault relay is de-energized if there is a
power interruption to the scanner or if the scanner has detected an internal fault.
APPLICATION
The InSight Series4 is best suited to combustion applications that require the highest level of sophistication and
flexibility (addition choices of modulation frequencies, and the time-saving Auto Config function), and remote
Modbus communications capability (e.g. larger multi-burner boilers and furnaces).
The InSight Series 4 scanner contains either the infrared or ultraviolet flame sensor described below. The
infrared flame sensor, responds to infrared radiation from 700 to 1700 nanometers wavelength. The ultraviolet
flame sensor, responds to ultraviolet radiation from 295 to 320 nanometers wavelength.
Functional safety proof test requirements
As a part of the Insight Series 4 Flame Scanner functional safety evaluation as a SIL3 capable product there is a
requirement for periodic proof testing of the safety function by the end user.
According to section 7.4.3.2.2 f) of IEC61508 proof tests shall be undertaken to reveal dangerous faults which
may be undetected by diagnostics test. This requires that it is necessary to specify how dangerous undetected
faults which have been noted during the failure modes, effects and diagnostics analysis can be detected during
proof testing

© 2020 Carrier 5
SUGGESTED PROOF TESTS
Active Flame OFF test - Shutdown the burner and ensure that the flame off condition is detected and signaled
by the flame detector as a flame off condition
Active False Flame test - verify that prior to start up (no flame present) there is no indication of a flame on
condition (false flame signal) on the flame scanner (this is typically integrated within the Burner Management
System as a pre-start permissive to prevent start up if a false flame condition is detected.
An alternative proof test can be performed if the burner cannot be shut down or is a critical process - see table
below
Table 1: Suggested proof test
Step Action
1. Bypass the safety function and take appropriate action to avoid a false trip.
2. Remove the flame or interrupt the path between the flame and scanner. Confirm flame relay
operation. Restore the flame or flame path.
3. Remove power to the flame scanner. Confirm alarm relay operation. Restore power to the scanner.
4. Remove the bypass and otherwise restore normal operation.
The suggested proof test interval and good practice is to carry out the proof test annually
The above covers the suggested proof test procedures and periodic proof test requirements in terms of
IEC61508. This should not be considered a replacement for recommended testing of the scanner
adjustments which are required to be verified each time the scanner is commissioned, adjusted, settings
are changed or re-commissioning takes place. In these cases the caution below should be implemented
by suitably trained engineers or qualified personnel who have been trained and are experience in the
requirements.
CAUTION: After selecting Sensor BAND, Sensor GAIN, and Flame Relay ON & OFF
Thresholds, proper flame detection and flame discrimination must be verified by starting
and stopping the burner several times. The flame relay must reliably de-energize for all
flame out conditions. This testing should be done with various adjacent burners on and off,
and at various load levels. This is a requirement for proper operation.

INSTALLATION NOTES
The InSight Series 4 flame scanners determine the presence or absence of flame by monitoring the
frequency spectrum of the flame. The scanner should initially be mounted so that the primary
combustion zone is within the scanner’s line of sight.
The location and sighting instructions listed in the following sections are rough guidelines for the
location of the scanner. The scanner provides feedback via its OLED display to assist in the adjustment
and proper alignment of the flame scanner. Refer to the setpoint procedures described in this bulletin.
Note: An acceptable scanner location must ensure the following:
Reliable main flame and/or ignitor flame detection at all air flow and furnace loads (ranges of fuel
firing).
Rejection of the ignitor flame if too short, or in the wrong position to ignite the main flame reliably,
thus prohibiting the delivery of fuel to the burner.
INSTALLATION PROCEDURE
WARNING: Protective filtered lenses should be worn when viewing flame. Infrared and
ultraviolet energy from the flame can be damaging to the eyes.
1. The best results are obtained when the scanner is aimed so that the scanner’s line of sight inter-
sects the burner center at a slight angle (e.g. 5 degrees) and sees a maximum of the primary com-
bustion zone, as shown in Figure 3. If only one scanner is used per burner, the line of sight should
also intersect the igniting flame.
2. For installations where separate scanners are used to monitor main and ignitor flames, the main
flame scanner should be sighted so it does not detect the ignitor flame.
3. The scanner should have an unrestricted view of flame as far as possible. Physical obstructions
such as air register blades, interfering vanes, or other hardware should be cut away or notched so
they do not fall within the scanner’s line of sight as shown in Figure 5.
Note: Always check with the burner manufacturer before you trim the register blades.
FIGURE 3. SINGLE BURNER SCANNER SI GH TI N G

© 2020 Carrier 11
4. Consideration must be given to burner secondary air rotation, some burners have clockwise
(CW) air rotation and others have counterclockwise(CCW) air rotation. If combustion air enters
the furnace with a rotational movement of sufficient velocity to deflect the ignitor flame in the
direction of rotation, position the scanner 10 to 30 degrees downstream of the ignitor as shown
in Figure 4 and close to the periphery of the burner throat (See Figure 3).
FIGURE 4. SCANNER LOCATION VS . SECONDARY AIR ROT A TION
CCW ROT A T ION CW R OT ATION
5. Having determined the approximate location for the sight pipe, cut a clearance hole for a 2 inch
pipe through the burner plate. Look through the hole. If register vanes interfere with the desired
line of sight, the interfering vane(s) should be trimmed to assure an unrestricted viewing path at
all firing levels as indicated in Figure 5.
Note: Always check with the burner manufacturer before you trim register vanes.
FIGURE 5. IF POSSIBLE, FLAME SHOULD COMPLETELY COVER SIGHT OPENING
NOT THIS NOT TH IS BUT TH IS OR THIS
6. The preferred method for mounting surface mounted scanners requires the use of a swivel
mount, P/N 60-1664-X, shown in Figures 7, 8, and 9. Center the swivel mount over the two inch
hole in the burner plate and secure using three hexed cap screws (not provided). Install the sight
pipe on the swivel mount. If a swivel is not used, insert the end of the sight pipe into the hole,
align the hole to the desired viewing angle and tack weld(welding must be adequate to temporarily
support the weight of the installed scanner). The sight pipe should be arranged to
slant downward so that dirt and dust will not collect inside.
CAUTION: Use no more than one foot of one inch diameter sight pipe. Increase the sight
pipe diameter one inch for every additional foot of sight pipe length used to avoid
restricting the scanner’s field of view.
When a satisfactory sighting has been confirmed by operational testing, secure the swivel
mount’s ball position in place by tightening the three hex head cap screws located on the
swivel mount ring.
7. In larger multi-burner type applications such as power, kiln or refinery burners, it is recognized
that there may be several obstructions within the scanner overall range of view. The same princi-
ple of adjusting the scanner such that the flame is within the center of its field of view applies.
Use of a swivel mount allows the scanner to be adjusted to target the flame within the center of
the scanner range of view. (See obstructed view in figure 6 above).
8. For ease of use, the scanner should be installed on the sight pipe so the OLED display can
easily be read.
Note: Operation of the display is independent of position.

9. The scanner lens must be kept free of contaminants (oil, ash, soot, dirt) and the scanner housing
temperature must not exceed its maximum rating of 150°F (65°C). Excessive temperatures will
shorten scanner life. Both requirements will be satisfied by a continuous injection of purge air at
either the 3/8” housing inlet or the 1” “Y” connection ahead of the swivel mount as shown in
Figures 6, 7 and 8.
Note: Internal scanner temperature is available via the display. See “Status Menu” under
“Programming the Scanner.”
The scanner mounting may be made with provision for purge air through only the 3/8” opening as
shown in Figure 8 or for purge air through either the 3/8” opening or the 1” “Y” connection as shown
in Figure 6. In the latter arrangements, normally only one of the two connections is provided with
purge air and the other connection is plugged. When a sealing coupling is used as shown in Figure 6,
the 1" “Y” connection is used for the purge air and the 3/8” opening is plugged.
It is good practice to use the sealing coupling (P/N 60-1199-X with NPT or BSP threads) on all
installations to insure against unwanted furnace pressures from damaging the scanner lens.
Under normal conditions, with clean burning fuels and moderate ambient temperature conditions,
purge air flow of approximately 4 SCFM (113 l/min) is generally adequate. Up to 15 SCFM
(425 l/min) may be required for fuels that produce high levels of ash or soot, or for hot environments
to maintain the scanner’s internal temperature within specification.
MECHANICAL ACCESSORIES
Surface Mounting Flange (Requ ire d )
Standard: Cast aluminum with gray polyester powder coat finish. Contains an integral heat-insulating female
thread insert (external heat-insulating nipple not required).
P/N 60-2919-1 1" NPT female pipe mount with 3/8” NPT female cooling air connection.
P/N 60-2919-2 1" BSP female pipe mount with 3/8” BSP female cooling air connection.
Optional: Cast aluminum with grey polyester powder coat finish. Does not contain heat-insulating insert.
P/N 60-2692-4, 1" NPT female pipe mount with 3/8" NPT female cooling air connection.
P/N 60-2693-4, 1" BSP female pipe mount with 3/8" BSP female cooling air connection.
Swivel Mount (Opti ona l)
The scanner swivel mount, P/N 60-1664-X (see Figure 9, Item A), is used to adjust the scanner
sighting angle after the scanner has been installed, The swivel mount is shown in Figures 6, 7, 8, and 9.
Sealing Coupling with Quartz Window (Op tio nal )
The sealing coupling, P/N 60-1199-x (see Figure 6, Item D), is used whenever a coupling or a seal is
required for scanner piping. The quartz window blocks furnace pressure, hot gases and soot from
coming in contact with the scanner and contaminating the lens. P/N 60-1199-1 has a 1" NPT thread,
p/n 60-1199-2 has a 1" BSP thread. When the sealing coupling is used, a 1 inch “Y” fitting must be
used downstream of it for connection of a purge air supply (plug 3/8”opening).
Orifice Kit ( O pti ona l)
An orifice may be used to restrict the scanner’s field of view aiding discrimination between the tar-
get flame and other flames in the combustion chamber. An orifice may also be used to reduce the
total amount of radiation reaching the scanner, thereby avoiding the chance of saturation. Orifice kit
(P/N 53-121) contains nine different orifice sizes, and two retaining clips. The orifice can be installed
either within the 60-1664 swivel mount, within the 60-1199 coupling, or within the 60-
2919-1, 60-2919-2 surface mounting flange. Refer to figures 10 and 11.
Cooling Cover/Vortex-Tube Cooler Kit (Op tio nal )
For high ambient temperature applications, a Cooling Cover (p/n 60-2930-x) and Vortex-Tube
Cooler Kit (P/N 60-2720) are available. Refer to bulletins 133-749 and CU-103 for details.

SCANNER WIRING
To reduce electrical noise interference, take precautions to keep the scanner cable away from any high
inductive wiring associated with high inductive loads or high voltage, high energy spark ignition sys-
tems.
CAUTION: The flame scanner requires 24 Vdc power for operation. Connection to a 24 Vac
or 120/230 Vac power source will damage the scanner. Refer to wiring diagrams.
External 0.5 Amp slow-blow fuses are recommended to protect Flame Relay and Fault Relay
contacts
All wiring to the scanner must be rated at 105°C. For runs less than 1000 feet, the use of Fireye
Scanner Cable P/N 59-547, (12 wire) is recommended. For runs in excess of 1000 feet, consult
the factory.
