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

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.
