might occur during operation and maintenance of the equipment described in this publication, personnel
are expected to use good engineering judgment when confronted with situations that are not specically
mentioned herein.
The contents of this publication are proprietary data of Forney Corporation. Reproduction or use of any
part of the publication for purposes other than the support of the equipment for which it is published is
permissible only if expressly authorized in writing by Forney.
Safety is YOUR responsibility and must always be primary concern. The guidelines covered in this
manual will greatly improve your ability to safely install and maintain this equipment. It is the equipment
owner’s responsibility to ensure that the concerned personnel fully understand and abide by all site-
specic Health, Safety, and Quality protocols. Safety summaries and procedures can never replace good
common sense!

SECTION 1
EQUIPMENT DESCRIPTION
The Forney IDDX ame amplier is a ame detector amplier designed for use with Forney IDD series of
ame detectors. The IDDX Flame amplier is suitable for use in a variety of industries such as oil, coal,
gas, etc. and across several applications such as gas-red industrial burners, utility burners, waste fuel
burners, duct burners and igniters.
The IDDX ame amplier is a stand-alone intelligent controller which includes two printed circuit boards
(PCB) assembled and packaged in a covered chassis suitable for mounting on a standard DIN rail.
The IDDX ame amplier may be installed in any orientation (horizontal or vertical DIN rail). The IDDX
amplier must be installed in a controlled environment (protected from dust & excessive heat). Screw
terminals are provided for electrical connections with external equipment.
The IDDX ame amplier provides power control, signal conversion, and processing control for Forney
IDD detectors (IDD II, IDD IIU, IDD IIL, Ultra). The IDDX is designed to work with any one of the following
Forney ame detectors:
Detector Forney Part Number
IDD II 3832121
IDD IIU 3832122
IDD IIL 3832123
IDD Ultra 3832129
Power printed circuit board (PCB) receives 24VDC input power from an external power source and
provides 5 VDC, 12 VDC, 15 VDC, & 50 VDC power for various circuits. The 15Vdc supply, powers IDD
detector heads directly while 50VDC provides bias voltage for the IDD detectors. Both 15 VDC and 50
VDC output to ame detector are protected by self-resetting fuses (PTC) .
The IDD ame detector produces an analog data signal whose amplitude and frequency vary with
light intensity. This signal is amplied using an adjustable gain amplier (0 through 15) and fed to
microprocessor for signal processing. Microprocessor runs FFT algorithm to provide signal intensity at
different frequencies. At regular intervals, the microprocessor compares those values with congured
tuning parameters from memory. When the count value exceeds the corresponding value from memory,
the microprocessor sets a ag to indicate ame presence.

The count values provide a direct measure of infrared or ultraviolet light intensity striking the respective
sensors. Accordingly, an analog output signal (4-20 ma) is provided to drive ame intensity meters or for
use in a control system. Analog output is driven by internally generated 15 Vdc and is protected by a self-
resetting fuse (PTC). The minimum and maximum scale values are user adjustable based on customer
requirements.
The IDDX amplier includes a self-check feature for ame detection system. Once ame is detected,
at user selected interval, IDDX runs a self-check routine to validate proper functioning of the system.
During self-check, 50 VDC Bias voltage to detector is removed for a brief period while processor monitors
detector signal to drop below ame relay drop out set point. If the ame signal from detector fails to
drop below the drop out set point, CPU triggers fault LED to lit, Flame relay to deenergize, Fault relay
to deenergize and locks out IDDX amplier in fault state until manually reset by technician by pressing
RESET push button.
Fault relay is normally energized to provide fail safe output and deenergizes on detection of fault. Thus,
fault relays contacts are in closed state until any fault is detected. The IDDX amplier checks for broken
wire or disconnected IDD detector head or loss of 15 VDC power to detector and triggers fault alarm when
such condition persist.
Any fault detected by rmware in the IDDX amplier, generates a corresponding error message that can
be downloaded to the Termiex/ SmartDisplay®. Any failure will be continually broadcast until reset
pushbutton is pressed.
The IDDX Flame Amplier faceplate has six (6) status LEDs to display real-time
operating conditions:
Flame (Green) Steady when the Flame Relay is in “ON” state.
Alarm (Red) Steady when the Detector faults; off otherwise.
WDT (Green) Flashing every second indicates normal operation; off during processor
internal fault except when detector is disconnected.
P1 (Green) Steady when Prole Select Input 1 is ON; off otherwise.
P2 (Green) Steady when Prole Select Input 2 is ON; off otherwise.
Self-CHECK (Green) Blinking on every period value set on Self check timer; off otherwise.
NOTICE: Analog output is generally representative of the ame intensity and
are intended for display on the operator console only. Analog output signal is not
representative of quality of combustion and must not be used as ‘loss of ame’ input to
safety control loop of the Burner Management System.

Operating Prole Select Inputs:
Two (2) prole select inputs are available for selecting up to four (4) different proles, numbered from
0 to 3 stored in its non-volatile memory. Each prole select input is sourced (5 VDC) from the detector
itself and must be wired to a potential free contact controlled by BMS or other control system. Do not
connect external power to prole select input terminals.
The stored proles are intended to allow for easy switching between commonly used burner operating
conditions without requiring manual re-tuning of the ame amplier. Each prole contains a full set of
operating parameters see Table 210 Operating Proles.
The amplier reads the prole selected by the Prole Select input code and displays the Active Prole
number in the lower right corner of the Termiex / SmartDisplay®. The Active Prole can be changed
at any time other than while in the tuning loop by repositioning the Prole Select inputs. Any tuning
parameter changes can be saved only to the Active Prole. Example: Active Prole 0 is displayed as
“Set 0”.

A serial communication port is located on the front of the IDDX. This port enable communication be-
tween the microprocessors on the board and a hand-held Termiex/ SmartDisplay® via RS422 commu-
nication protocols.
Upon completion of installation, the user must connect the Termiex/ SmartDisplay® to the amplier
and revise the tuning parameters suitable to detect the presence and absence of target ame. Us-
er-supplied tuning parameters are stored and remain unchanged until overwritten with new tuning
parameters.
