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.
