51 Feedback potentiometer total resistance problem—Fuel 1.
52 Feedback potentiometer total resistance problem—Fuel 2.
53 Feedback potentiometer total resistance problem—FGR.
54 Internal memory function problem—Air.
55 Internal memory function problem—Fuel 1.
56 Internal memory function problem—Fuel 2.
57 Internal memory function problem—FGR.
58 Stuck Reset button.
61 Actuator(s) not reaching lightoff point.
65 Internal memory fault.
66 Internal Initialization Error. A2D error, 4-20ma (terminal 39-40) is being
overdriven.
67 Fuel actuator off curve (selected fuel type). Actuator did not go to its
commanded position.
68 FGR actuator off curve.
69 Air actuator off curve. Actuator did not go to its commanded position.
71 Verifies that the Air actuator accepted the offline, online, move counter-clock-
wise and move clock-wise commands. Furthermore, all potentiometer tests
must be successfully passed to bring an actuator online.
72 Verifies that the Fuel 1 actuator accepted the offline, online, move counter-
clock-wise and move clock-wise commands. Furthermore, all potentiometer
tests must be successfully passed to bring an actuator online.
73 Verifies that the Fuel 2 actuator accepted the offline, online, move counter-
clock-wise and move clock-wise commands. Furthermore, all potentiometer
tests must be successfully passed to bring an actuator online.
74 Verifies that the FGR actuator accepted the offline, online, move counter-clock-
wise and move clock-wise commands. Furthermore, all potentiometer tests
must be successfully passed to bring an actuator online.
75 Internal memory fault (Microprocessor test failed).
76 Internal checksum error (Microprocessor test failed).
82 Actuator secondary fault (actuator secondary fault - check footnote a).
83 Air actuator nonresponsive.
84 Fuel 1 actuator nonresponsive.
85 Fuel 2 actuator nonresponsive.
86 FGR actuator nonresponsive.
87 Internal math error (Microprocessor test failed).

Turn off remote reset switch; check operation of controller reset button. Check
the manual pot for correct wiring (terminal 36 - 38).
Check for actuator wiring problems or stuck valves or dampers. Place controller in
standby and use actuator manual keys to verify actuator travel. Were the actuators
commissioned properly?

Reset control. Remove 39-40 input and reset R7999C, if fault clears,
R7999C is ok, and correct 4-20 source.
Check for stuck fuel actuator and/or proper shielding on actuator interface. Try
changing degree of accuracy to 0.5 degree.
Check for stuck FGR actuator and/or proper shielding on actuator interface.
Check for stuck air actuator and/or proper shielding on actuator interface. Try
changing degree of accuracy to 0.5 degree.
Check wiring of actuator, verify correct ID is being used. Watch actuator LED
to verify that the actuator is being brought online.
A fast flash in the actuator equals offline status, while a one-second flash
equals online status.
