MC120E REMOTE RESET CHASSIS
The MC120RE and MC230R Chassis provides remote reset capabilities in the event of a lockout
condition. The remote reset chassis can be reset in any of the following ways:
1.
Depress and release the reset button built into the chassis. This reset button will always reset the
control.
2.
To reset the control via a remote pushbutton. Wire a momentary dry contact pushbutton into the
two (2) terminals located on the chassis (on the same PC board as the built-in reset switch) and
depress the button for one (1) second. The maximum distance the remote reset switch can be
wired from the control is 1,000 feet (300M).
CAUTION: Remote reset is recommended only on a control solely for proved ignition pro-
gramming (pilot ignited burner) or a control for use only with appliances in which unburned
fuel cannot accumulate and that is intended for installation in inaccessible locations such as
open-flame, ceiling-suspended gas heaters.
LED INDICATOR LIGHTS
The 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 the air flow switch is closed between Terminals #8 and
#6, and power is on Terminal #8.
PTFI:
This LED is energized only during the Ignition Safety Time.
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 “re-ignition” 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 ORDER-
ING INFORMATION on Page 4 for the appropriate part numbers.
Pilot Ignited Burners
The typical wiring arrangement illustrated on Page 16 for pilot ignited burners provides the follow-
ing 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 6 sec.), 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. When power is restored, the control will restart.
