Warning!
• Risk of electric shock. Exposed components carry dangerous voltages. Make sure that the power
supply is switched off before you remove the cover of the electronics compartment.
• Risk of damaging electronic components (ESD protection). Static electricity can damage electronic
components or impair their operability. Use a workplace with a grounded working surface
purposely built for electrostatically sensitive devices!
• If you cannot guarantee that the dielectric strength of the device is maintained in the following
steps, then an appropriate inspection must be carried out in accordance with the manufacturer’s
specifications.
• When connecting Ex-certified devices, see the notes and diagrams in the Ex-specific supplement
to this Operating Manual.

Caution!
Use only original Hauser parts.
Installing and removing the circuit boards

2.
Remove the screws securing the electronics module (2). Then push up electronics module and
pull it as far as possible out of the wall-mount housing.
3.
Disconnect the following cable plugs from amplifier board (7):
– Electrode signal cable plug (7.1) including S-DAT (7.3)
– Plug of coil current cable (7.2):
Loosen the plug locking and gently disconnect the plug from the board, i.e. without moving
it back and forward.
– Ribbon cable plug (3) of the display module

5.
Remove the boards (6, 7, 8):
(5) Insert a thin pin into the hole provided for the purpose and pull the board clear of its holder.
6.
Removing sub-modules (8.2, only for measuring devices with convertible I/O board):
No tools are required for removing the submodules (inputs/outputs) from the I/O board.
Installation is also a no-tools operation.
"
Caution!
Only certain combinations of submodules on the
I/O board are permissible.
The individual slots are marked and correspond to certain terminals in the connection
compartment of the transmitter:
“INPUT / OUTPUT 3” slot = terminals 22/23
“INPUT / OUTPUT 4” slot = terminals 20/21
7.
Installation is the reverse of the removal procedure.
