Disassembly
Refer to Drawing Number E04439 . Remove and retain the 3 screws and washers and the Case
Top (E02780:BK). De-solder the Cable (E04042) connections from the PCB, remove the strain
relief Cable Tie (200026) and withdraw the cable and Grommet (E03701) through the bottom Case
(E02781). The PCB, complete with Gimballed Element (E02782) can then be lifted clear from the
Case Bottom. If required, the Gimballed Element can be de-soldered and removed form the PCB.
Assembly
Fit the Gimballed Element (E02782) through the slot in the PCB (E03791) and twist to lock in
place. The arrow on the securing flange of the Gimballed Element should be closest to the straight
edge of the PCB. Terminate the element connections on the PCB. Fit the Cable (E04042) through
the Case Bottom (E02781:BK) and Grommet (E03701) and secure it with a Cable Tie (200026) to
provide strain relief. Terminate the cable on the PCB. Fit the PCB into the Case Bottom
(E02781:BK), the Case Seal (E02783) into the recess and bring the 2 parts of the case together.
Place Washer (200184) into each of the screw recesses and fit the screws ensuring that the N0.4 x
_” Screw (200137) is fitted to the front of the case and the longer No. 4 x 1” Screws (200235) are
fitted towards the flat edge at the rear. Tighten the screws to make a good seal and test to
specification.
NB. It is advisable to replace the Case Seal to ensure that a watertight seal is made.
