screw driver.

Unscrew the screws C, pull the inner

When carrying out service, replacing a circuit board, etc., it may be necessary to remove
and refit various parts of the positioner. This is described on the following pages.
Read the Safety Instructions on page 3 and 4 before starting work on the positioner.
Cleanliness is essential when working with the positioner. Contamination in the air
ducts will inevitably lead to operational disturbances. Do not disassemble the unit
more than that described here.
Do not take the valve block apart because its function will be impaired.
When working with the PMV D3 positioner, the work place must be equipped with
ESD protection before the work is started.
Always turn off the air and electrical supplies before starting any work.
Please see section for special conditions for safe use and spare
parts on page 4.
Please contact a Flowserve office for information regarding proper procedures.
