In both cases, the serial number of the sensor is needed. The serial
numbers are stated on the type label of the instrument, on the inside
of the housing as well as on the delivery note.
When loading on site, first of all the order data must be downloaded
from the Internet (see operating instructions manual "
Electronics
module
").
Caution:
All user-specific settings must be entered again. Hence, you have to
carry out a new setup after the electronics exchange.
If you have stored the data of the parameter adjustment during the
first setup of the sensor, you can transfer these to the replacement
electronics module. A new setup is no more necessary.
9.6 Exchanging the rod
The rod (meas. part) of the probe can be shortened, if necessary. To
loosen the meas. rod you need a fork spanner with spanner width 10.
Caution:
Remember that the polished rod of the food version is very sensitive
to damage and scratching. Use special tools in order to avoid damag-
ing the surface.
1. Loosen the rod by applying a fork spanner to the flat surfaces
(SW 10), provide counterforce manually on the process fitting
2. Twist off the loosened measuring rod manually
3. Shift the attached new seal ring onto the thread.
4. Screw the new rod carefully by hand to the thread on the process
fitting.
5. Exert counterforce manually and tighten the rod on the flat sur-
faces with a torque of 6 Nm (4.43 lbf ft).
