Quanta Flame 5004-M-85 Flame Safeguard Controller

Application | Overview | Technical

A state-of-the-art flame safeguard controller designed for single burner boiler applications with one or two scanners. Unlike Fireye E-110 series and Honeywell 7800 series flame safeguard controllers that require a multitude of amplifiers, programmers, and purge timers, the Preferred 5004-M-85 has just one processor with a built-in universal amplifier that accepts UV, IR, and self-checking UV scanner inputs, as well as flame rod inputs. In addition, Purge times and Main Trial For Ignition (MTFI) times are field-selectable.

Unlike most flame safeguard controllers that require amplifiers, programmers, and purge timers, the Preferred 5004-M-85 has just one processor with a built-in amplifier that accepts UV, IR, and self-checking UV scanner inputs, as well as flame rod inputs. It can also accepts two scanners simultaneously on separate inputs. In addition, Purge times and Main Trial For Ignition (MTFI) times are field-selectable.

Controller Functions

False Flame Detection: The controller will Lockout if flame is detected during Standby or Purge.

Safe Start Check: During every burner startup sequence, the controller performs hardware & software self-tests to verify it’s internal circuitry is functioning properly. The controller verifies the safety relay, ignition relay, pilot relay, and the main fuel valve relays are functioning properly. If the “check for power failure” function is selected and power was interrupted during a firing cycle, upon power up the control will Lockout.

Check for Limits Bypassed: If the “Check for limits bypassed” function is selected, before beginning Purge, the controller ensures the Limits Made input is de-energized, and waits for up to 60 seconds for the Limits Made input to be de-energized. (The fan motor starter interlock and minimum air pressure switch should not be made before the fan is powered. This function will detect if these limits have been bypassed.)

Proof of Valve Closure (POVC): The controller will Lockout if the main fuel valves are not proven closed during Standby, Purge and Pilot Trial for Ignition (PTFI). The controller will also Lockout if the main fuel valves close when the burner is firing.

Proven High Fire / Purge: Proves that the high fire position and purge air flow interlocks are made before Purge can begin, and requires these interlocks to be made throughout the Purge period. If these interlocks open during the Purge period for more than 30 seconds (cumulative), the controller will lockout. If running interlocks are not made continuously throughout the Purge period, the control will lockout after 5 minutes. This ensures a proper Purge cycle.

Proven Low Fire / Ignition: Proves the low fire position prior to Ignition and light off of the burner. If low fire proving switch is not made within 5 minutes the control will Lockout.

Selectable Pilot Trial for Ignition (PTFI) Time: DIP switches allow selection of a 3, 5, or 10 second timing.

Early Spark Termination / Pilot Verification: The ignition transformer spark is de-energized at the end of PTFI while the pilot valve continues to be energized for 5 seconds before the main fuel valves are energized. This ensures the sensor is not recognizing spark as a  (false) flame and the pilot flame is stable without a spark, before lighting the energizing the mail fuel valves.

Selectable Main Trial for Ignition (MTFI) Time: The default MTFI time is 10 seconds. Some #6 oil burners may require a 15 second MTFI to allow extra time for the cold oil to flow to the burner. Energizing terminal 27 changes the MTFI time from 10 seconds to 15 seconds.

Pilot Test Mode: In this mode, after the completion of PTFI, the ignition transformer is de-energized, the pilot valve remains energized, and the controller will not attempt to open the main fuel valves. If the flame sensor stops detecting a flame the controller will Lockout. This mode permits the technician to examine and adjust the pilot flame.

Electrical 

Voltage: 120 VAC +10% - 15%, 50/60 Hz

Power Consumption: 2 VA

Flame Failure Response Time: 2.5 to 3.5 seconds

Purge Time: 30, 60, 90, 150, 180, 300, 450, or 900 seconds (DIP switch selectable)

Pilot Trial for Ignition Time: 3, 5, or 10 seconds (DIP switch selectable)

Flame Sensor Inputs (2): Infrared, Ultraviolet, Flame Rod 

Controller Configuration

Configuration of the controller is done by setting the DIP switches located under the LCD display.

DIP switch 1 sets the power-up response of the controller.

DIP switches 2 through 4 set the purge timing.

DIP switches 5 and 6 set the desired Pilot Trial for Ignition (PTFI) time.

DIP switch 7 activates the Limits Bypassed check. When DIP switch 7 is ON, the controller waits up to 60 seconds for the Limits Made input to de-energize. After 60 seconds the control will lockout. When DIP switch 7 is OFF, the control will continue into Purge even if the Limits Made input is energized when the Start input is energized.

DIP switch 8 is used for configuring Modbus. During normal operation, DIP Switch 8 MUST be OFF.

NOTE: After 4 hours of continuous operation, ALL current DIP switch settings will be recorded in non-volatile memory. Subsequent DIP switch changes will be ignored.
