Using a flat blade screwdriver on the slots on edge of cams, or your fingers, rotate the cams
until the switches are set. (See Figure 31)

The auxiliary switches should be set so switches #3 and #5 operate in synchronism with
switch #1 (i.e., both activating when the drive is going in the same direction) and set
switches #4 and #6 to operate in synchronism with switch #2. See Figure 32 for auxiliary
switch settings.

For Switches #3 and #5:
•
Rotate the actuator shaft, using the manual handwheel or the auto-manual switch, to the
desired low scale position.
desired low scale position.
•
Rotate the #3 switch operating cam to activate at this position. The switch roller arm should
go from being in an up, not depressed state, to a depressed state as the cam is rotated in
the direction of the shaft rotation going toward the limit position. This will cause the switch to
go from NC to NO and turn off the power to the motor when the switch activates. Switch
activation may be detected by the clicking sound or with a continuity tester connected to the
terminals.

Double check limit switch actuation by first manually driving the actuator to each end of travel
and hearing the switch click or by detecting it with a continuity tester. Secondly, drive the
actuator to both ends of travel (using the auto/manual switch or by providing minimum and full
input signal) and make sure the switches activate and turn off the motor.
