Go Linkageless and Say Goodbye to the Jackshaft Forever

Mechanical cam and linkage systems used to control the fuel-air ratio of a fully modulating power burner represent a great disadvantage to the equipment operator in regard to fuel usage, burner efficiency, dual fuel usage and burner turndown. Because mechanical linkage systems have one foot-mounted actuator to position both the combustion air and the fuel at the same time, the result is compromised fuel-air ratio and dual fuel efficiency to obtain reliable combustion throughout the fuel-air curve. Typically mechanically linked systems utilize the same point for light-off and low fire, which reduces fuel efficiency because many burners are capable of operating at a lower firing rate than light-off. As with any mechanical system, what happens over time is loss of precision due to component wear and shifting, equating to erosion of the fuel-air curve and non-optimal performance as well as unnecessary fuel costs.

With the ever increasing price of fuel and emphasis on emissions, achieving optimal burner efficiency has never been more critical  and requires a cost-effective and enduring solution. Enter Honeywell’s ControLinks Linkageless Fuel Air Control System, which provides consistent and reliable fuel-air ratio control thanks to precision microprocessor control and integral actuator position feedback potentiometers. Four separate Universal Parallel Positioning Actuators (UPPAs) replace the single actuator used with mechanical cam and linkage systems, providing independent control of the combustion air damper, the primary fuel, the secondary fuel and the FGR damper (if used). The UPPAs are commanded by the ControLinks Controller, which responds to load and firing rate demands. Further, ControLinks offers dual fuel flexibility, allowing two independent fuel curves, providing maximum efficiency for both fuels. Because the burner fuel to air ratio is adjusted independently, the result is maximized burner efficiency and reduced fuel consumption that typically pays for the ControLinks system within a year.

One controller, four actuators and optimal burner efficiency.  It all adds up to monumental savings you can’t afford to ignore! So go linkageless with Honeywell’s ControLinks and reap the benefits. You have everything to gain and inefficiencies to lose!

Product Overview  

The ControLinks Fuel Air Ratio Control System is a microprocessor-based control that simultaneously controls from two to four actuators associated with a full modulation power burner. Actuators control the position of primary and secondary fuel valves, the combustion air damper and the FGR (Flue Gas Return) damper, if used.

The system consists of the R7999 master controller and its Q7999A wiring subbase and the ML7999A actuators. Two controller models, 100 – 120Vac and 200 – 240Vac, cover global applications. Controller non-volatile memory stores operating history and current lockout and alarm status and has 6 LEDs for Power, Alarm and 4 Actuator Status Lights. Fault annunciation via blinking power light, with 60 possible fault codes. Floating control output to UPPAs, auto/manual firing rate input, remote reset capability, 4 – 20mA stack or water temperature input and dual fuel input. Control from 2 to 4 UPPAs. Password required for parameter adjustment to prevent unauthorized access.

UPPAs have universal power input of 100 to 240 Vac, providing flexibility in application with direct coupled output. A large arrow on the actuator face provides instant visual indication of actuator position. Floating control input with 950 possible actuator positions, output hub position accuracy of ±0.1 angular degrees and CW and CCW switches for manually driving hub. A mechanical stop with a magnetic coupling between stepper drive motor and the gear train assures gears will not strip or burn out the motor in an overload condition. Actuator LED Annunciation for Unconfigured, Configured and On-Line or Faulty Actuator States.
