Safety instructions
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
• Before starting work on the device, make sure that it has
cooled sufficiently.
Aggressive or corrosive media may lead to the damage of
wetted parts of the sensor. As a result, measuring medium under
pressure can leak out.
Wear to the flange gasket or process connection gaskets
(e.g. pipe fitting, Tri-clamp, etc.) may caused a pressurized
measuring medium to escape.
When using internal flat gaskets, they can become brittle
through CIP- / SIP processes.
If pressure surges above the permissible nominal pressure of the
device occur permanently during operation, this may affect the
service life of the device.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
Checks before commissioning
The following points must be checked before commissioning:
• The power supply must be switched off.
• The power supply used must match the information on the
name plate.
• The terminal assignment must be made in accordance with
the electrical connection.
• Sensor and transmitter must be grounded properly.
• The temperature limit values must be observed.
• When the sensor (SE41F, SE21, SE21F) and transmitter (S4)
are delivered as a pair, the data memory module (external
FRAM) is located in the sensor. The data module stores the
sensor data, e.g., size, Cs, Cz, type, etc., as well as the setup
data on the transmitter after commissioning.
• Prior to commissioning, plug the external FRAM for the
appropriate sensor (order no. is printed on the FRAM and, if
available, a TAG no.) to the terminal board for the installed
transmitter. Then screw to the connection board (captive).
