1.
Remove the socket head screws (M5 hex wrench) from the manifold cover and remove the manifold
cover to reveal the transducer wiring, transformers, and transducer housings. Alternatively for the
single transducer enclosure style meter remove the transducer cover.
Note – Removal of the covers requires the removal of the security seal. Once the cover is re-installed, a
new seal should also be installed.
2.
For manifold style meters disconnect the transducer leads from the transformer terminal block. If
necessary, remove the transformer circuit board, shown below in Figure 7.9.
Figure 7.9 Transformer Circuit Boards
Remove the compression plug retaining the transducer by pushing in and turning clockwise to release
(pliers might be helpful to get a grip on the knurled head). Figure 7.10 shows the notches that will need
to be aligned before the transducer can be re-installed (pins on the sides of the compression plug go
into the notches).
Refer to Figure 7.11 for a view of the transducer being removed.
