(h)
Locate R6 on the printed circuit
board. Turning the adjustment
screw of R6 clockwise will turn the
voltage at terminals #20 and #21
of TB 1 (5) on for a given setting
of the test rheostat. Turning
adjustment
screw
counterclockwise
turns
the
voltage at terminals #20 and #21
off. Adjust screw as required to
achieve voltage cutoff and turn on
for eighty percent of maximum
rotation as described in steps (d),
(e), and (f). Troubleshooting is
complete
after
adjustment
is
made.
NOTE
nt of R6 does not cause the voltage at terminals #20
and #21 of TB I (5) to vary. Either
voltage will be on or voltage will be off.
WARNING
Turn off 115 VAC power source before attempting any
inspection or repair.
(i)
Inspect circuit board for burned or
broken printed circuit board paths.
If burned or broken paths are
present, circuit board should be
replaced.
(j)
Locate components R1 and R2.
Refer to Figure 7-15 for a wiring
schematic. Apply 1 15 VAC to
terminals #24 and #27 of terminal
strip TBI (5, Figure 7-13).
