CONTROL END REPLACEMENT

The following procedure describes the steps

required to replace the Control End assembly

using the control end replacement kit part number

12-8065-05 or -15. The kits include the control

end which is comprised of a contactless position

sensor (CPS-4), a limit switch assembly, some

screws and washers, and a control end gasket for

replacement, if necessary.

The replacement control end assembly has

been fully calibrated at the factory. This replace-

ment procedure will return the actuator to a close

approximation of its original calibration. Do not

calibrate the actuator until this procedure is com-

plete, and then only if necessary.

REQUIRED TOOLS

1/2” socket

3/32” hex driver

Torque wrenches

(appropriate for 12 lb-in and 10 lb-ft)

Fine point marker

3/16” flat-tipped screwdriver

WARNING

Electrical shock hazard. Disconnect

power before proceeding. Remove

the actuator from line voltage and

disconnect any external power

sources feeding the auxiliary switches.

CAUTION

To prevent electrostatic discharge

damage to the electronics, wear a

grounding strap during this procedure.

PROCEDURE

Remove the old control end assembly:

1. Remove power from the actuator.

2. Remove the control end cover (cylinder shape),

using care not to bend the control shaft or

damage the position-sensing assembly inside.

3. Disconnect the control end assembly electrical

circuits by unplugging the three multi-pin

connectors from the actuator. Two connectors

lead from the switch subassembly and the

other connector leads from the Printed Circuit

board. To disconnect the switch subassembly

connectors, use a 3/16” flat-tipped screwdriver

to press the release tab straight back (see

Figure 5) and pull the plug out of its socket.

The connector leading from the P.C. board

slides off with modest force.

4. Loosen the two outermost setscrews on the

coupling.

Do not

loosen the inner setscrews.

5. Use a fine point marker to note the position of

the control end relative to the actuator body.

Mark the drive’s face immediately adjacent to

the top of the notch (see Figure 6).

6. Loosen (do not remove) the four mounting

clamp button head screws (3/8” long) and

slide the top clamp up over the edge of the

shoulder in the body, immediately above the

stator flange (see Figure 6). Snug one of the

screws to hold the clamp up while replacing

the assembly. Allow the bottom clamp to hang

by the screws.

7. Slide the control end assembly away from the

actuator body until it clears the control end

shaft.
