Flowserve 75 10-23 Series Motor Module - Manual

Motor module kits are intended as repair kits for 10-23 75 electric
actuators. Diagrams show typical installation of these kits, which
should be installed exactly as the motor modules they are replacing.
a CAUTION: Be sure actuator is disconnected from power
source.
To replace a motor module, do the following:
1. Remove the four 8-32 slotted hex head screws (and on 23
size only, the four 6-32 slotted screws on the outside corners
of motors) that secure the motor module in place. (A motor
module is the complete motor/gearbox assembly.)
2. Disconnect the electrical leads as follows:
AC: Loosen terminal strip screw at terminal 1, to which white
motor lead is secured, and remove white wire. Remove all wir-
ing connectors at the capacitor.
DC: Using a wire cutter, cut all lead wires at the closed end
splice, as close to this splice as possible.
Loosen terminal strip screw at terminal 1, to which the red
wire(s) are attached, and remove red wire(s).
Strip ¼ " of insulation from each end of the blue wires that were
spliced.
3. Cut cable ties as required and remove motor module from the
actuator.
4. On AC voltage actuators remove and replace capacitor. Position
capacitor with connectors at 45° to base so that leads do not
touch cover.
5. Install the new motor module, securing in place with the four
8-32 mounting screws. Locate the motor module in the identical
manner as it was removed.
NOTE: For 23 size only, four additional screws on the outside
corners of motors are also used to secure motor module. Prior
to mounting, remove any temporary fasteners holding these
screws in place.
6. Reconnect motor leads, as shown, keeping all wires away from
any rotating parts (shaft and motor module pinion). Wiring to
terminal strip should be inserted only to midpoint of terminal
strip.
DC: Using the new closed end splice, insert the blue leads and
black motor lead(s) into the splice and crimp it closed. Tuck the
splice underneath the limit switch.
7. The actuator’s cam settings are not affected by changing a
motor module. Operate actuator to verify proper operation.
8. Replace cable ties, as shown. Trim off excess tie and revolve so
as to not interfere with cover.
9. SPECIAL NOTE
AC Actuators: Observe the following when installing AC motor
modules:
When the motor module is located with “output-fast” closest to
center shaft, connect actuator wires, as shown (10, 15 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.
