FLAME SAFEGUARD CONTROLS

WARNING: Selection of this control for a particular application should be made by a com-

petent professional, licensed by a state or other government agency. Inappropriate application

of this product could result in an unsafe condition hazardous to life and property.

DESCRIPTION

The Fireye® M4RT1 Flame Safeguard Control is a compact burner management system. It is

designed to provide automatic ignition and continuous flame monitoring for commercial sizes of

heating and process burners that use gaseous fuels.

Flame monitoring is accomplished by a Flame Rod detector, the built in amplifier and programmer.

Control functions and timing are factory set with onboard jumpers. Functions such as recycle/non-

recycle, purge timing, and pilot trial for ignition (P.T.F.I.) time are determined by the jumpers. Flame

Failure Response Time (F.F.R.T.) is fixed at three seconds. LED indicator lights indicate the operat-

ing status of the control.

In the event of ignition failure, or following a safety shutdown, the unit locks out, activating an

alarm circuit. Cycling the power OFF and back on will reset the control. A manual reset option can

be special ordered. Remote reset (via remote pushbutton) is also available as a special order option.

A detailed description of the programmer sequence is found later in this document. Test jacks are

provided to permit flame signal measurement during operation.

The M4RT1 control incorporates a safety checking circuit that is operative on each start. If flame

(real or simulated) is detected prior to a start or during the purge, the fuel valves will not be ener-

gized, and the unit will lock out.

All M4RT1 controls do not require a wiring base due to the terminals included on the relay board.

See INSTALLATION OF CONTROL, SCANNERS, AND FLAME DETECTORS (page 2) for tem-

perature and wiring requirements.

® INSTALLATION OF CONTROL, SCANNERS, AND FLAME DETECTORS Wiring Base Mount the control in an enclosure/burner panel that provides the proper protection for the control. The location should be free from moisture, excessive vibration and within the specified ambient temperature rating. The control may be mounted in any angular position. All wiring should comply with applicable electrical codes, regulations, and local ordinances. Use moisture resistant wire suitable for at least 90 degrees C.

® 5. 6. 7. If the flame is partly luminous, the electrode tip should extend only to the edge of the flame. It is not necessary to maintain absolutely uninterrupted contact with the flame. It is preferable to angle the rod downward to minimize the effect of sagging and to prevent it from coming in contact with any object. An adequate grounding surface for the flame must be provided.

® RESET In the event of a lockout condition, the M4RT1 can be reset via a minimum one second power interruption to terminal 7. RESET OPTIONS (Special Order) 1. 2. Optional M4RT1 reset push button. When this optional reset pushbutton is installed, the M4RT1 can be reset by depressing this button for a minimum of one second. Remote reset option. With this option, the M4RT1 is provided with two additional screw terminals. Using those terminals, a remote, dry contact pushbutton switch can be connected.

® Pilot Trial for Ignition Jumpers JP6 and JP7 are used by the factory only to select the PTFI for the M4RT1. The available PTFI timing selections are 5 and 10 seconds. The factory set, default PTFI time is 10 seconds (JP6 installed, JP7 not installed). The PTFI time may only be set by the factory. Recycle/Non-recycle Operation Jumper JP8 is used to select either Recycle or Non-Recycle operation of the M4RT1. The factory set, default is Recycle operation (JP8 installed).

® 6. 7. 8. In the event the pilot flame is not detected by the end of trial for ignition period (PTFI), the pilot gas valve (Terminal 3) and spark ignition (Terminal 4) are de-energized. A safety shutdown occurs followed in approximately 30 seconds by a safety lockout that de-energizes the blower motor (Terminal 8) and energizes the lockout alarm circuit (Alarm LED lighted). In the event of a flame failure during a firing period, the pilot and main fuel valves are de-energized.

® Minimum Pilot Test This test insures that the flame detector will not sense a pilot flame too small to light the main flame reliably. It must be made on every new installation as well as following the repositioning of the flame detector. This procedure should not be used on a direct spark ignited burner. 1. 2. 3. 4. 5.
