To turn the cams, insert small screwdriver (1/8" or
3 mm blade) through wiring box into slot on cam and move
the screwdriver at the top. Refer to Fig. 3. Each division on
the cam represents 15° of motor rotation.
A) Two position motors (M8185):
1. Turn off power and remove cover of wiring box.
2. Determine amount of shaft rotation, in degrees,
desired before switch is energized.
3. Note the position of the cam slots and, with screw-
driver, rotate the cam to the desired position for switch
action. Each division on the cam represents 15° of motor
rotation. Therefore, if 60° of motor rotation is desired
before switch operates, rotate the cam 4 divisions from the
reference point.
4. Connect auxiliary equipment to auxiliary switch
leads. See Wiring section.
5. Turn on power and check for proper switch differen-
tial and switching of auxiliary equipment by driving the
motor through full stroke (in both directions). If necessary
repeat steps 3 and 5 until correct switching action is
obtained.
6. Replace cover of wiring box.
