INTRODUCTION This manual contains information for the UNIFLAME Flame Detector / Amplifier, provided by Forney Corporation, 3405 Wiley Post Road, Carrollton, Texas. All personnel should become thoroughly familiar with the contents of this manual before attempting to operate or maintain the system. Because it is virtually impossible to cover every situation that might occur during operation and maintenance of the equipment described in this publication, personnel are expected to use good engineering judgement when confronted with situations that are not specifically mentioned herein.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H SECTION 1 DESCRIPTION Forney’s UNIFLAME Series flame detectors utilize micro-processor based technology combined with solid state infrared (IR), ultraviolet (UV), or dual (IR and UV) sensors. An adjustable flame relay resides in the body of the UNIFLAME Series flame detector, eliminating the need for a remote amplifier.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 1.2 APPLICATION The InfraRed Model (P/N 401111-01) contains an infrared flame sensor, responding to wavelengths in the infrared range from 700 nm to 1700 nm. This sensor is best suited for all oil and coal fired applications.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H SECTION 2 INSTALLATION NOTES The detector should be mounted so that the primary combustion zone is within the detector’s line of sight. The primary combustion zone from a flame emits the majority of the frequency spectrum used by the detector to determine the presence or absence of the flame.

Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 3. Consideration must be given to burner secondary air rotation, some burners have clockwise (CW) air rotation and others have counter clockwise (CCW) air rotation. If combustion air enters the furnace with a rotational movement of sufficient velocity to deflect the igniter flame in the direction of rotation, position the detector 10 to 30 degrees downstream of the igniter as shown in Figure 5 and close to the periphery of the burner throat.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H SECTION 3 DETECTOR WIRING All wiring to the detector should be rated at 90°C. For runs less than 1000 feet, the use of Forney detector cable P/N 405842-XX is recommended. For runs in excess of 1000 feet, please consult the factory. To reduce the electrical noise interference, the detector cable should be installed in rigid or flexible conduit.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 3.1 GROUNDING AND SHIELDING TECHNIQUES FOR USE ON DETECTORS OR DETECTOR CABLE LOCATED WITHIN 12 INCHES OF A HIGH ENERGY OR HIGH VOLTAGE SOURCE. 1. The detector and cable (preferably in flexible conduit) must be located at least 12 inches from the ignition source.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 3.3 WIRING HARNESS ASSEMBLY LAYOUT To provide a service point at the burner front or an easy method to wire the UNIFLAME Series flame detectors in a “multi-drop” configuration for remote communications, Forney offers a wiring harness in four different lengths (10, 15, 20, 30 Ft.).
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H SECTION 4 REMOTE COMMUNICATIONS Remote Communications with the UNIFLAME Series flame detector uses an RS485 Interface to carry out communications with an IBM compatible PC running Forney’s SMARTDisplay Software. The wiring configuration for remote communications is dependent on the distance between the detector and the PC.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 4.1 REMOTE FILE SELECTION The UNIFLAME Series flame detectors have more than one internal memory file. The user has the option of storing different detector setpoints for different operating conditions (e.g. gas/oil, pilot/main, low load/high load, etc.) in these files.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H SECTION 5 PROGRAMMING UNIFLAME DETECTORS 5.1 KEYPAD/DISPLAY Figure 14 – Keypad/Display The UNIFLAME Series detectors use an eight (8) character alphanumeric LED display and four (4) push buttons (Figure 14) to review and program various setpoints and operating parameters. The functions of the push buttons are: ▲▼...
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2 UNIFLAME MENU STRUCTURE For ease of operation, the UNIFLAME Series detectors contain 2 menu loops, STATUS LOOP and SETPOINT LOOP, that can be viewed and/or accessed via the keypad/display. 5.2.1 STATUS LOOP The STATUS LOOP menu loop is the default loop and appears as soon as power is applied to the detector.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2.1.1 STATUS POINTS DEFINED Flame Quality The Flame Quality number can range from 0 to 100. The number represents the detector’s 4-20 mA analog flame Signal Strength output in percent. The Flame Quality is the scale by which the internal flame relay’s ON and OFF Thresholds are configured.

Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H With “PASSWORD” displayed, press SELECT. “0xxx” appears, where the first digit shown is adjustable via the UP/DOWN keys. With the appropriate first digit selected, press PROGRAM to confirm the value and move on to the next digit (“00xx”).
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2.2 SETPOINT LOOP The SETPOINT menu loop consists of the AUTOTUNE and EDIT modes. The AUTOTUNE mode allows the detector’s processor to automatically tune the setpoints based on the appropriate target flame and background flame data, while the EDIT mode allows the user to manually configure the tuning setpoints.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2.2.1.1 AUTOTUNE SETPOINTS DEFINED Aim Detector Pressing the SELECT key causes, “Ix Ux” to appear (MultiSpectral Models only). The value of “x” may range from 0 to 60. The value displayed represents the intensity of the flame for the entire band (flicker frequency spectrum) as individually sensed by the IR (Ix) sensor and/or UV (Ux) sensor(s).
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2.2.2 EDIT MODE The EDIT mode contains all the user-selected setpoints for the UNIFLAME Series detectors. The EDIT mode can be used to program the detector directly, or can be used to fine-tune the AUTOTUNE mode. The EDIT mode is entered from the STATUS LOOP after entering a four-digit password.
Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H 5.2.2.2.1 EDIT MODE SETPOINTS DEFINED File Select The user can manually choose which file to run (and edit) by selecting this menu choice provided the Remote File Select “KEY” choice is selected. If the user wants to edit the contents of a file, they must first select and run that particular file.

Forney Corporation UNIFLAME User’s Manual Publication 372000-48 Rev H UV Gain The display is divided into two halves. The left side displays the selected UV Gain (uG31). The right side displays the Signal Strength attributed to the UV sensor. For example a reading of uG26/600, would indicate an UV gain of 26 with a corresponding Signal Strength of 600.
