Once the switches are set, they become permanently stored after 8 hours of continuous operation or
they can be manually set through the use of the optional ED510 display. Refer to the section using
the optional ED510 display for detailed information.
Where applicable, each MicroM programmer is shipped with dip-switch 6 set to non-recycle on
flame fail, dipswitch 4 set to 5 second PTFI time, and dipswitches 1 & 2 set to the longest purge
time.

Dipswitch Definitions
Purge Time: Begins after power is detected on Terminal #7 (limit control) and Terminal #6 (running
interlock switch) and no flame (real or simulated) is detected.
Post Purge : If enabled, Terminal #8 (blower motor or contactor) will remain energized for 15 sec-
onds after terminal #7 or Terminal #6 is detected as open.
PTFI Time : The maximum length of time that Terminal #3 and Terminal #4 will be energized after
the pre-purge period to detect pilot flame. For all programmers, the MicroM forces a 3 second delay
before advancing to the next logic module (Stabilization, MTFI or Auto) after flame is detected
during the PTFI period. This is to allow establishment of a pilot and stabilization of the fuel flow.
Prove Air Flow Open: After power is detected on Terminal #7 (limit control) and before energizing
Terminal #8 (blower motor or contactor) no power must be detected on Terminal #6 (running inter-
lock switch). If power is detected on Terminal #6, the MicroM will hold for 60 seconds after which
safety lockout will occur. On recycle operation, if this is enabled, Terminal #8 will be de-energized to
allow Terminal #6 to open.
Recycle / Non-Recycle: Applies to flame failure during the Run condition. If a flame failure occurs,
the control will de-energize Terminals #3 and #5 and if Recycle is selected a new prepurge period
will begin. Lockout will occur immediately and the alarm will energize 15 seconds after flame fail-
ure if Non-Recycle is selected. Unless otherwise stated (see Programmer Description), the MicroM
recycles on all occurrences of air flow failure. The MEP235 and MEP562 will always initiate a lock-
out on flame failure.
LED INDICATOR LIGHTS
All MicroM Programmer Modules have 5 LED lights to indicate the operating status of the control
and also to display the coded sequence under locked out conditions. The function of the lights under
a normal operating condition is:
Operating Control: This LED is energized whenever the burner control switch and all other various
limit switches are closed and power is applied to Terminal #7.
Interlock or Air Flow: This LED is illuminated whenever power is detected on Terminal #6, indi-
cating the air flow switch or other running interlock is closed. If the operating control is closed and
the running interlock switch remains open, this LED will flash at a 1 second rate indefinitely for the
MEP100 and MEP200 family. Lockout will occur if the switch remains open for 10 minutes in the
MEP500 family. This LED will blink when configured as a flame switch and flame detected.
