FRONT FACEPLATE
The front faceplate of the FlameWorx modules provides LED indicator lights and flame signal test
jack points for current status and failure mode analysis, and two communication push-buttons for
LonWorks communications.
FIGURE 2.
TEST JACK POINTS
SIG1, SIG2 and COM:
These three (3) test jack points provide access via the front face-
plate to measure flame signal strength for each flame relay. The output signal is a current
source 4-20 mA signal. Maximum connected load not to exceed 750 ohms. SIG1 refer-
enced to COM provides the flame signal for Channel #1, and SIG 2 referenced to COM pro-
vides the flame signal for Channel #2.
Minimum acceptable flame signal
6 mA.
Average flame signal
8-20 mA.
LED STATUS INDICATORS
POWER:
The green LED will blink when power (24 VAC/VDC) is applied to the Flame-
Worx module (terminal 13 and 14 - Refer to Wiring Diagram).
RLY 1 and RLY 2:
These two (2) green LED's will light when the scanner detects flame
for the appropriate flame switch.
LED FAULT INDICATORS
FAULT:
These two (2) red LED's will light and/or blink in the manner described below to
indicate the following fault conditions:
Fault Condition
Corrective Action
CPU failure.
Replace FlameWorx module.
Communication failure.
Check communication wiring
Check communication master.
Press CS1 and CS2 communication push-buttons.
Set dipswitch #6 to On position (for stand alone
module).
Shutter check failure on
Check shutter operation on scanner.
Channel 1.
Check UV tube on scanner.
Shutter check failure on
Check shutter operation on scanner.
Channel 2.
Check UV tube on scanner.
COMMUNICATION PUSHBUTTONS:
CS1 and CS2:
These two (2) push-buttons are associated with LonWorks communications. After all
wiring connections between the FlameWorx module and designated master device (e.g. Fireye MB
Module, host PC, etc.) are complete, press
each
push-button
one time
to establish the communica-
tion link between the FlameWorx module and the designated master. These push-buttons do not need
to be pressed a second time unless the address of the master device or the master device itself is
changed. A “Fault” indicator LED will light momentarily when each CS1 push-button is pressed.
Also refer to dipswitches #1 through #5 (Communication Address) and dipswitch #6 (stand alone or
network mode).
LED is Off
LED is On.
LED is blinking.
