Replacement and Troubleshooting

The display, secondary electronic, and transducer assemblies are not user-serviceable; however, they may
be replaced. This section describes the dismantle, the replacement and the troubleshooting of these
assemblies. Other components are not replaceable except at the factory. As an example the housing covers
viewing glass. This because regulations do not permit field replacement of a broken or damaged glass as
this would invalidate the enclosure's explosion proof rating. Therefore it is necessary to replace the entire
damaged enclosure cap assembly.

Dismantling and reassembly

Dismantling and reassembly should not be carried out on site because of the risk of damage to components
and printed circuits as a result of adverse environmental conditions such as humidity, dust, etc. The
dismantling and reassembly procedures given below should be carried out in the listed order to avoid
instrument damage. See the pictures at the end of the instructions for better understanding.
Operation required tools
3 mm Allen key (in the transmitter box)
Small Phillips screwdriver
Small flat-bladed screwdriver

Safety information for Dismantling and Reassembly

Read the following Safety information before to start any operation.
Only specialist personnel or ABB may undertake dismantling and reassembly of certified devices.
Process fluids and/or pressure retained in the transmitter primary unit can cause severe injury and death or
damage to the equipment. It is the user responsibility to make sure that no pressure is applied before
removing the instrument from service or when draining or venting.
For Hazardous classified Location installations, at least seven (7) threads on the cover must be engaged in
