IV. INTERNAL ASSEMBLY REPLACEMENT
Tools Required:
Flat head screw starter
Flat head screw driver
Towel or rag for clean-up
A.
Old Internal Assembly Removal
1. The internal assembly has been designed to minimize the number of steps required for re-
placement. The assembly will come as a motor and bracket sub-assembly that simply re-
places the old motor, bracket and switches.
2. Before removing the cover to the housing, disconnect all power supplies to the paddle switch;
i.e. open power supply breakers, switches, etc.
3. Unscrew the housing cover to expose the interior switch assembly.
4. With power disconnected, disconnect all field wiring from both the power terminal strip and to
the switch contact terminals. Disconnect the field ground wire connection.
5. Remove the unit from service and perform the remaining steps in a clean work area or bench
setting. It is strongly recommended not to attempt repairs on the unit while it is in an installed
state.
6. Using a flat head screw driver, small to medium head size, unscrew and remove the two 4-40
threaded mounting screws that secure the bracket assembly to the base of the instrument
housing as shown in Figure 9. Retain the screws for re-installation.
7. Lift out the switch assembly from the housing.
