2 Series 75 10-23 Motor Module FCD WCAIM2066-00
When the motor module is located with “output-slow” clos-
est to center shaft, connect actuator wires as shown except
interchange grey and yellow motor leads at the motor capacitor
(12 and 22 size actuators). If capacitor has metal retaining ring,
insulating fi ber washer must be used.
For 20 75 actuators, 100% duty cycle, the motor module is
mounted to the actuator with the “output-slow” closest to the
center shaft. As before, interchange the grey and yellow leads
from the motor at the capacitor. If capacitor has metal retaining
ring, insulating fi ber washer must be used.
SPECIAL NOTE
DC Actuators: Observe the following when installing DC motor
modules:
When the motor module is located with “output-fast” closest to
the center shaft, connect actuator wires as shown (10 and 20
size actuators). For 23 size only, wires are connected as shown,
except that motor module is located with “output-slow” closest
to center shaft.
When the motor module is located with “output-slow” closest
to the center shaft, connect actuator wires as shown, except
interchange the wiring location of the motor’s red and black
leads. The black wire(s) are connected to terminal 1, while the
red wire(s) are crimped with the blue wires (12 and 22 size
actuators).
Alternatively, the supply voltage polarity may be reversed to
accomplish the same thing. That is, if the motor module is
located with “output-slow” closest to the center shaft, simply
reverse supply voltage polarity for proper operation. Never do
both!
If in special circumstances DC motor is mounted on top of gear-
box from AC motor module, the bearing from gearbox has to be
removed to eliminate bindings. (DC motor has two bearings in
the housing already.)
