Precautions and Warnings
CAUTION
•
Check if the specifications of the transmitter meet the needs of the process conditions
•
When the EJA564E is used as a level transmitter, be aware of the place where the transmitter is
mounted. Here are some suggestions:
•
DO NOT mount a level transmitter in- or near filling or discharging pipes.
•
In case of automatic cleaning systems or hand cleaning: never point the water jets on the
diaphragm, take necessary steps to avoid this. This will void the warranty.
•
When the EJA564E is used as a pressure transmitter, be aware of the following points:
•
Rapid closing valves in combination with high flow velocity will cause water hammer(spikes) and
can destroy the transmitter. DO NOT mount a transmitter near such valves, always a few pipe
bends away up or down stream (avoid suction).
•
Install a pressure transmitter a few pipe bends away from pumps, as well on the suction or
pressure side of the pump.

Welding Information
CAUTION
•
When using the EJA564E process connectors suffix code “W
□□
”, the welding information on
page 6
must be followed exactly. This is very important to prevent distortion of the weld-on
nipples. It also
prevents the screw thread from the EJA564E from being deformed.
•
The diaphragm of the transmitter is protected with a special protection cap. Protect the diaphragm until
installation takes place
to prevent damaging of the diaphragm.
•
Configuring the transmitter local
ly
and remote
ly
simultaneously will cause transmission errors and must be
prevented.
•
As soon as the wiring is brought inside through the cable gland and connected to the terminal board,
make sure the cable gland is tightly fixed so that moisture cannot enter into the electronics housing.
•
Avoid high pressure water-jets pointed at the venting.
•
If the ambient conditions are very wet, we advise to use a venting through the cable. A special vented
cable can be connected on request. (The normal venting will be removed) In that case the transmitter is
IP68
rated.
•
The covers must be fully engaged
s
o that moisture cannot ingress into the electronics housing.
