6.23 Flag Adjustment
As noted above, the shaft crank screws onto the threaded output shaft extending
from the gearbox. On the opposite end of this shaft is a thin metal "flag" which
operates in conjunction with two optical sensors to signal the motor to start and
stop. (Figure 17) For the actuator to function properly, this flag must be positioned
in correct relationship to the newly installed crank assembly.
1. With the 1/4" open-end wrench, reach between the circuit board and the
gearbox and loosen the hex head screw that holds the flag in position in
front of the sensors.
2. From the same viewpoint previously described (motor down and away, cast-
ing in front), position the flag at three o’clock. Partially tighten the screw so
that the flag stays in place but can still be moved.
3. Turn the actuator cover so that the writing is upside down and slide it on the
actuator far enough to allow the connectors to be plugged back onto the
board. The manual switching cable has six wires, while the remote switching
cable has only five. They connect to the same row of eleven pins, with the
six wire connector closest to the motor. (See Figure 17.) The three wire
lead which supplies power goes on with the green wire to the outside. Plug
in the actuator.
Caution: The following steps describe adjustments which require the
use of metal tools in close proximity with electrical circuits. Checking
the result of the adjustments requires that the actuator be plugged in,
but remember to unplug the actuator before further adjustments are
made.
4. Step the actuator from position to position two or three times. Look through
the adjustment hole (Figure 14) in the front casting to see if the arms of the
crank assembly are parallel. They should look like Figure 23, with the shaft
crank virtually hidden behind the other arm. If they do, unplug the actuator,
tighten the screw which secures the flag, and proceed to Step 5 in Section
6.1, Adjusting the Actuator Stroke. If they do not, proceed to the next
step.
5. Unplug the actuator. If the arms are off in the direction of Figure 21,
move the flag
slightly toward 6 o’clock. If they are off as in Figure 22, move
it slightly toward 12 o’clock.
6. Plug the actuator in and repeat Steps 4 and 5 until proper adjustment is
achieved.
7. Proceed to Step 5 in Section 6.1, Adjusting the Actuator Stroke.
