TERMINAL 17 IS USED ONLY TO DRIVE THE SHUTTER ON A C7012E OR
F OR A C7076A ULTRAVIOLET FLAME DETECTOR WITH SELF-CHECKING
FEATURE. POWER TO DRIVE THE SHUTTER IS APPLIED TO TERMINAL 17
FROM TERMINAL 8 THROUGH A SOLID STATE SWITCH IN THE R7247C
OR R7476A DYNAMIC SELF-CHECK AMPLIFIER. REFER TO SAMPLE
BLOCK DIAGRAM OF FIELD WIRING.
TERMINAL 16, ON THE WIRING SUBBASE ONLY, IS USED AS A TIE POINT.
IF START INTERLOCK(S) IS NOT USED, A JUMPER IS INSTALLED
BETWEEN TERMINALS 16 AND 4 ON THE WIRING SUBBASE.
A JUMPER IS INSTALLED ON THE BACK OF THE PROGRAMMER TO OBTAIN 60
SECOND INTERRUPTED PILOT/IGNITION AT TERMINAL 6; WITHOUT JUMPER,
IT IS 30 SECONDS.
FOR DIRECT SPARK IGNITION OF OIL, A JUMPER IS INSTALLED BETWEEN
TERMINALS 6 AND 7. REFER TO SAMPLE BLOCK DIAGRAM OF FIELD WIRING FOR
HOOKUP OF IGNITION AND MAIN OIL VALVE SOLENOID.
SOME AUTHORITIES HAVING JURISDICTION PROHIBIT THE WIRING OF ANY LIMIT OR
OPERATING CONTACTS IN SERIES WITH THE MAIN FUEL VALVE(S).
TIMER SWITCH IS SHOWN IN NORM POSITION; IT IS OPEN IN TEST POSITION.
USE A SERIES 90 MODULATING MOTOR.
