NOTE: Controls with UV amplifiers (MAUV3 and MAUV1T) are always powered via Terminal #1.
5. In the event the pilot flame is not detected by the end of the trial for ignition 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 circuit (Alarm LED lit) approximately 10 to 30
seconds after the safety shutdown occurs.
6. In the event of a flame failure during a firing period, the main fuel valve is de-energized and the
spark ignition re-energized. A 10 sec. trial for ignition is initiated (PTFI LED lit). If flame is
detected (Flame LED lit) during the trial for ignition period, the main fuel valve is re-energized
and the spark ignition de-energized. If flame is not detected during the trial for ignition period,
the pilot gas valve and spark ignition are de-energized. A safety lockout occurs which de-ener-
gizes the burner motor and energizes the lockout alarm circuit (Alarm LED lit) approximately
10 seconds after the safety shutdown occurs.
7. Manual reset is required following any safety lockout.
NOTE: Wait 10 seconds after lockout before resetting the control.
Direct Spark Ignited Burners
The typical wiring arrangement illustrated on Page 16 for direct spark ignited burners provides the
following function:
1. With power applied, and the limit-operating control circuit closed (Operating Control LED lit),
the burner motor circuit is energized. The air flow switch circuit closes (Air Flow LED lit).
2. Following a short-time delay (4-6 sec.) KL-1 closes, energizing Terminal 3 which powers the
primary main fuel valve and Terminal 4 which powers the spark ignition. A 10 sec. Trial for
ignition is initiated (PTFI LED lit).
3. When main flame is detected (Flame LED lit), KF-1 closes, energizing Terminal 5 which pow-
ers the secondary main fuel valve (if used), KF-2 opens de-energizing Terminal 4 which shuts
off the spark ignition.
4. When the operating control opens or if a power failure occurs, the control is de-energized. When
power is restored, the control will restart.
NOTE: Controls with UV amplifiers (MAUV3 and MAUV1T) are always powered via Terminal #1.
5. In the event that main flame is not detected by the end of the trial for ignition period, the primary
main fuel valve and the spark ignition are de-energized. A safety lockout occurs which de-ener-
gizes the burner motor and energizes the lockout alarm circuit (Alarm LED lit) approximately
10 to 30 seconds after the safety shutdown occurs.
6. In the event of a flame failure during a firing period, the secondary main fuel valve (if used) is
de-energized and the spark ignition is re-energized. A 10 sec. trial for ignition is initiated (PTFI
LED lit). If flame is detected (Flame LED lit), the secondary main fuel valve (if used) is re-
energized and the spark ignition de-energized. If flame is not detected during the trial for igni-
tion period, the primary main fuel valve and the spark ignition are de-energized. A safety lock-
out occurs, which de-energizes the burner motor and energizes the lockout alarm circuit (Alarm
LED lit) approximately 10 to 30 seconds after the safety shutdown occurs.
7. Manual reset is required following and safety lockout.
NOTE: Wait 10 seconds after lockout before resetting the control.
APPLICATION AND FUNCTION - MP102 and MP102E
The MP102 and MP102E operates in the same manner as the MP100 and MP100E with the follow-
ing exceptions. The standing pilot and re-ignition features have been eliminated. The ignition safety
time has been changed to 5 seconds and the control will lockout on flame failure.
