Product Overview

Setting the Switches

Once the appropriate switches are set, slide the clear plastic window to the left so that it covers the

switches and LOCKS into place. This action causes the control to become operable with the settings

programmed from the dipswitches. The plastic window CANNOT be moved, and the dipswitches

and their settings CANNOT be changed without causing the control to become inoperable. If the

control does require alternative timings, the programmer module will have to be removed and

replaced with another module with the appropriate dipswitch settings.

LED INDICATOR LIGHTS

The MP100, MP230, MP230H, and the MP560 Programmer Modules have 5 LED lights to indicate

the operating status of the control. The function of these lights are:

Operating Control: This LED is energized whenever the burner control switch (Terminal #7) along

with the various limit switches, operating controls and fuel interlocks are closed.

Air Flow: This LED is energized whenever power is detected between Terminals #8 and #6, indicat-

ing the air flow switch has closed.

PTFI: This LED is energized only during the Pilot Trial For Ignition Period.

Flame On: This LED is energized whenever a flame signal is detected by the UV scanner or Flame

detector.

Alarm: this LED is energized whenever a safety lockout occurs. (See APPLICATION AND FUNC-

TION section).

APPLICATION AND FUNCTION - MP100, MP100E

The MP100 and MP100E Programmer Modules are designed as a replacement for the Fireye M1

Series “relight” controls. It provides ignition and Flame Safeguard for heating or process light oil or

gas fired burners. The Amplifier Module should be selected based on the type of flame scanner (UV

scanner or flame rod), and the required Flame Failure response Time (F.F.R.T.). See ORDERING

INFORMATION on page 4 for the appropriate part numbers.

Pilot Ignited Burners

The typical wiring arrangement illustrated on pages 26 (MC120, MC230) or 29 (MC120P) for pilot

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 to 6sec.), KL-1 closes, energizing Terminal 3 which powers the

pilot gas valve, and Terminal 4 which powers the spark ignition. A 10 sec. trial for ignition is

initiated (PTFI LED lit).

3. When pilot flame is detected (Flame LED lit), KF-1 closes, energizing Terminal 5 which pow-

ers the main fuel valve, and KF-2 opens, de-energizing Terminal 4 which shuts off the spark

ignition.

4. When the operating control opens its circuit, or if a power failure occurs, the control is de-ener-

gized. Power interruptions in the millisecond range do not affect the operation of the control.

Power interruptions of longer duration will cause the control to recycle.

NOTE: Controls with UV amplifiers (MAUV1 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 30 seconds

after the safety lockout occurs.
