364xS User's Manual

Installation

Study these installation instructions carefully before proceeding. Failure to observe the warnings and
instructions may cause a malfunction or personal hazard.
As already specified in the Safety Notes the installation must only be carried out by suitably trained
personnel and in accordance with the information given. Any deviation from these instructions, will transfer
the complete liability to the user.
It is not recommended to install the transmitter and leave the cover open or the electical input without the
appropriate plugs. Water penetration can damage the electrical circuit.

Preparing for installation

Before installing the transmitter check its compatibility with the following measurement and safety
requirements:
Explosion protection
Pressure rating (Maximum Working Pressure and measurement range)
Operating voltage limits
Process and ambient Temperature limits
Environmental limits (EMC, vibration, others)
Corrosion compatibility of transmitter wetted parts and process media

Mounting the transmitter

Position the process connection to enable process connections to
be made.
It is important to mount the transmitter and to lay the process
piping so that gas bubbles, when measuring liquids, or
condensate when measuring gases, will flow back to the process
and not enter the transmitter measuring chamber.
Vent/drain valves on the transmitter are located on the body. The
transmitter and these drain/vent valves have to be located higher
than the taps on liquid service in order to allow the venting of
entrapped gas or below the taps on gas service in order to allow
the air vent off or condensate to drain off.
.
For safety reasons, take care of the drain/vent valves position so
that when the process fluid is removed during the drain/vent
operation it is directed down and away from technicians.
It is recommended to mount the transmitter to prevent this
possible source of damage for unskilled operators.
