Safety Shutdown
In the event pilot flame is not detected at the end of the 10 second PTFI period, the pilot gas valve
and spark ignition are de-energized. A safety lockout occurs which de-energizes the burner motor
and energizes the lockout alarm relay circuit, lighting the Alarm LED, 15 seconds after the safety
lockout occurs. Manual reset is required.
In the event of a flame failure during a firing period, the main fuel valve is de-energized (Terminal 5)
and the spark ignition is re-energized (Terminal 4), the PTFI period begins again as described above
under Normal Operation.
In the event of the interlock switch opening, the main fuel valve and pilot valve are de-energized.
The control reverts back to the Idle state and begins again a new cycle starting with the safe start
check period.
Direct Spark Ignited Burners
Refer to typical wiring arrangement illustrated on pages 40 and 41.
Normal Operation
With power applied and the limit operating control circuit (1-7) closed, the Operating Control LED
illuminates, the burner motor circuit is energized (Terminal 8).
The interlock proving switch (7-6) closes, the INTRLCK LED is illuminated and a short time delay
period (3 seconds) begins (safe start check period).
At the expiration of the safe start check period, a 10 second PTFI period is initiated. The PTFI Led is
illuminated, power is applied to Terminal 3, energizing the main fuel valve and to Terminal 4, ener-
gizing the spark ignition.
At the detection of main flame, the FLAME LED is illuminated, and the programmer holds that posi-
tion for 3-5 seconds to allow the main flame to stabilize.
Power is then removed from Terminal 4, turning off the spark igniter.
When the operating control opens, the control de-energizes Terminal 3 and Terminal 5 and the pro-
grammer reverts back to an Idle state. Terminal 8 is immediately de-energized.
Safety Shutdown
In the event the main flame is not detected at the end of a 10 second PTFI period, the main fuel valve
and spark ignition are de-energized. A safety lockout occurs which de-energizes the burner motor
and energizes the lockout alarm relay circuit, lighting the Alarm LED, 15 seconds after the safety
lockout occurs. Manual reset is required.
In the event of a flame failure during a firing period, the secondary fuel valve (if used) is de-ener-
gized and the spark ignition is re-energized, the PTFI period begins again as described above under
Normal Operation.
In the event of the interlock switch opening, the main fuel valve and pilot valve are de-energized.
The control reverts back to the Idle state and begins again a new cycle starting with the safe start
check period.
MEP102 & MEP104
The MEP102 and MEP104 programmers operate the same as the MEP100, except the PTFI time is
limited to 5 seconds and 10 seconds respectively, the relight feature is eliminated and instead, the
control will enter safety lockout on flame failure. Recycle to the start of safe start check period to
begin a new cycle will occur on air flow switch opening.
MEP103
The MEP103 programmer implements a fixed 10 second spark igniter sensing period (SISP) used to
detect spark, followed by a 10 second main trial for ignition (MTFI). Safety lockout occurs on flame
failure during the main firing period (AUTO). Recycle occurs on air flow switch opening. If spark is
not detected during the spark igniter sensing period the control makes one attempt to establish pilot
