Note: If a particular installation does not have operational switches in all three circuits listed above,
(such as an installation where there is no High-Fire -Purge switch installed, and a permanent
jumper is wired between terminals D-8), dipswitch 6 should not be enabled.
DESCRIPTION OF DIPSWITCH FUNCTIONS
PROGRAMMER AND DISPLAY MODULE COMPATIBILITY
Two display modules are available for the FLAME-MONITOR control system (P/N's ED500 and
ED510). The ED500 is an 8 character LED display that physically mounts in the card rack of the
EB700 chassis. The ED510 is a 2 line by 16 character LCD with keypad to provide both current and
historical information pertaining to the operation of the control. The ED510 display physically
mounts onto the front cover of the programmer module. Refer to Bulletin ED5101 for a complete
description of the features and capabilities of the ED510 display module. Programmers with an
Engineering code of 28 or later (e.g.: 9414-28) are compatible with both the ED510 and ED500 dis-
play module. Programmers with an Engineering code before 28 are only compatible with the ED500
display.
IMPORTANT INFORMATION — PLEASE READ CAREFULLY
DETECTING AIR FLOW SWITCH (3-P) CLOSED AFTER START
In code 39 programmers and above, the method used to detect the air flow switch closed at the begin-
ning of a cycle has been changed to avoid any nuisance lockouts. Currently, after the operating con-
trol closes, the programer waits 10 seconds for the air flow switch to close and if not closed will go
into lockout. The EP programmers utilize the open damper switch interlock, D-8, to determine the
wait time for the air flow switch to close. If, at the start of a cycle after a blower turns on, the D-8
interlock is detected as closed, most likely indicating a jumped high fire switch, the programmer
allows 20 seconds for the air flow switch to close. Alternatively, at startup, if the D-8 interlock is
open, indicating the firing rate motor is at the low fire position and the damper is closed, the pro-
gramer will not check for the air flow switch closed until 10 seconds after the open damper switch
has closed and the purge period has begun. This means the programmer will send the mod motor to
the high fire position, forcing the high fire damper switch to close, and will then begin its 10 second
timer to check for the air flow switch to close.
