Product Overview

APPLICATION AND FUNCTION - MP560, MP561, MP562

The MP560, MP561, MP562 Programmer Modules are designed as a direct replacement for the Fir-

eye M5 Series “non-recycle” controls and M6 Series “recycle” and “non-recycle” controls. It pro-

vides prepurge, ignition and flame safeguard for heating and process light oil or gas fired burners.

The “recycle” or “non-recycle” operation is determined by the position of dipswitch #8 on the Pro-

grammer Module. Purge timing as well as trial for ignition timing is also set by the dipswitch set-

tings. See PROGRAMMER DIPSWITCH SETTING on page 11.

A “run-check” switch is provided to assist in testing size, position, and stabilization of pilot in con-

junction with the flame detector. See page 28.

Amplifier and Scanner Selection

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 - “Recycle” Operation

With dipswitch #8 in the “recycle” position, the typical wiring arrangement illustrated on pages 29

(MC120, MC230) or 30 (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 circuit closes (Air Flow LED lit).

2. Following the selected prepurge period (as determined by dipswitches #1 through #5), KL-1 and

K1-1 close, energizing Terminals 3 and 4 which powers the pilot valve and the spark ignition. A

5 or 10 sec. (as determined by dipswitches #6 and #7) trial-for-ignition initiates (PTFI LED lit).

3. When pilot flame is detected (Flame LED lit), an 8 sec. pilot stabilization period begins fol-

lowed by KF-1 closing. Ten seconds after KF-1 closes, Terminal 4 is de-energized.

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 at 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 trial for ignition period, the pilot 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.

6. In the event of a flame failure during a firing period, the pilot and main fuel valves are de-ener-

gized. Following the prepurge period (as determined by dipswitches #1 through #5), with proven

air flow (Air Flow LED lit), the pilot valve and spark ignition are re-energized and a 5 or 10 sec.

(as determined by dipswitches #6 and #7) trial-for-ignition is initiated (PTFI LED lit). If pilot

flame is detected (Flame LED lit), the main fuel valve is energized, the spark ignition and pilot

are de-energized. If the pilot 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-energizes the

burner motor and energizes the lockout alarm circuit (Alarm LED lit) approximately 30 seconds

after the safety lockout occurs.

7. Manual reset is required following any safety lockout.

NOTE: Wait 10 seconds after lockout before resetting the control.
