HANDSWITCH
To replace the Handswitch, remove the
terminal cover, and then remove the terminal
plate (11-209/-269, -309/-369, and -409/-469
only). Clip the five wires from the old Handswitch.
Remove the knob and the nut under the knob to
remove the switch. Install the new Handswitch
as shown below. Splice the wires color for color.
Inspect the terminal plate gasket and replace if
necessary. To ensure a watertight seal between
the plate and the gasket, coat the gasket with a
thin film of grease before replacing the terminal
plate. Torque the screws to 3 Ib-ft (4 N•m). Do
not over-torque. Replace the terminal cover.
Torque bolts to 10 Ib-ft (14 N•m).

DCM-2 BOARD
Field service of the DCM-2 board is not
recommended. The factory maintains a stock
of replacement boards for immediate shipment.
To replace the DCM-2 board, remove the Digital
Control Module compartment cover (1/2" bolt
heads). If applicable, disconnect the torque
sensing wires from the bottom of the customer
interface panel by gently pulling on the connector.
Loosen the four captive screws holding the
board to its mounting pads. Note the “L” shaped
mounting bracket on the end of the board. To
remove the board, pull the mounting bracket away
from its mating surface. See illustration below.

To install a DCM-2 board, lightly press the board
connector into its receptacle until the mounting
bracket is flush with its mating surface. Tighten the
four captive screws to 8 lb-in (.9 N•m). If applicable,
connect the torque sensing wires to the bottom of
the customer interface panel by gently pressing
the connector into its receptacle. Replace the
compartment cover. Torque cover bolts to 10 lb-ft
(14 N•m).

CPS-2
Field repair of the CPS-2 assembly is not
recommended. The factory maintains a stock of
replacement assemblies for immediate shipment.
If it is necessary to replace the CPS-2, replace
both the rotor and stator / circuit board assembly.
When returning the CPS-2 to the factory for
service, include the rotor and stator / circuit
board assembly. Do not separate the stator or
circuit boards from their mounting plates. The
rotor should be held inside the stator with rubber
bands for protection during shipment.
