Quanta Flame 5004-M-78 Replacement Flame Safeguard Controller
Direct Replacement for Cleaver-Brooks CB780 and Honeywell RM7800 Series Flame Safeguard Controllers - 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 accept two scanners simultaneously on separate inputs. In addition, Purge times and Main Trial For Ignition (MTFI) times are field-selectable.
Mount into existing Q7800A1005, Q7800B1003, or CB 780 (833-2725) wiring sub base
Direct replacement for most RM7800E, RM7800L, and CB780 flame safeguard controllers
Includes, and replaces the programmer, display module, flame amplifier, and purge timer of the existing system.
- Overview and Features
- Interfaces to Infrared, Ultraviolet, Ultraviolet Self Check or Flame Rod Sensors
- Single or Dual Flame Sensors
- Optional Remote Display (5004-216RN)
Our 5004-M-78 replaces an existing:
- Control chassis
- Display module
- Purge timer
- Flame amplifier
As with the 5004-M-85, the flame amplifier inputs are universal. Purge timing, PTFI timing, and other control functions are determined by DIP switch selection.
The 5004-M-78 Flame Safeguard Replacement Chassis is specially designed to mount into existing Q7800A1005, Q7800B1003, or CB 780 (833-2725) wiring sub bases. It is a direct replacement for most RM7800E, RM7800L, and CB780 flame safeguard controllers. As with the 5004-M-85, the flame amplifier, through a jumper selection can accept UV, IR, or Flame Rod inputs. Purge timing, PTFI timing, and other control functions are determined by DIP switch selection.
Note: The 5004-M-78 includes, and replaces the programmer, display module, flame amplifier, and purge timer of the existing system.
Enclosure: 7” L x 5” W x 2” D
Weight: 2 lbs
Operating Temperature: -40° F to +140° F (-40° C to +60° C), UV scanners -20° C to 60° C, IR scanner -30° C to 65° C
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
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.
