Dismantling of CPM 223

• Consider potential effects on process

when removing the instrument from service!

• First pull off the terminal block (item 422 b)

on the rear of the instrument to de-energize
the instrument.

• Then pull off the terminal blocks (items 422

a and 430 if applicable) on the rear. Now
you can dismantle the instrument.

• Push the end frame latches (item 340)

inward and pull off the frame towards the
rear.

• Loosen the special screw (item 400) by

turning it counterclockwise.

• Remove the complete electronics block

from the housing. The modules are
plugged together mechanically and can be
easily separated:

Simply pull the processor/display module
off towards the front

Pull the back plate tabs outward slightly
to remove the lateral modules.

• Removal of pH/mV transmitter (item 230):

Bend the screen plate upward

Pull off the stranded wire (plug-in
connection; pH input from BNC socket),
then pull off the module towards the top.

8.4.3

Assembly of CPM 223

• Reverse the dismantling sequence for

assembly.

• Hand-tighten the special screw without

using a tool.

• Incorrect assembly is not possible!

A module block which has been plugged
together incorrectly cannot be inserted in
the housing.
