Ex i-devices: The repair has to be performed such, that the voltage isolation of the Ex ia circuits against ground is maintained.
If required, a test can be performed with 500 Veff over a time period of 60 s.
Ex d-devices: Attention has to be paid not to damage the threads.
In other case the part has to be exchanged.

Mounting the sensor on housing
1
Insert new sealing ring into the groove in the
housing, take care to the mounting position.
2 Insert new locking ring at the sensor head
The locking ring limits the alignment of the housing
on the sensor.
3 Exchange both O-rings at sensor head.
4
Place housing on sensor head and screw it on the
sensor until stop (9 turns).
After appropriate assembly the housing can be turned for
more than a complete turn (380°) until the locking ring
stops the rotation.
Mounting the instrument
• Assembly of the complete instrument has to be done
in the reverse order to the disassembly,
see page 1 (step 5 ... 1 ).
• Re-install Deltapilot S, connect cables at terminal.
• Adjust housing to desired position.
Important:
After the alignment of the housing tighten the set
screw firmly to achieve an optimal potential
equalization between process vessel and ground of
the housing. Especially the electromagnetic
compatibility of the electronics will be improved.
Calibration
• After the assembly has been completed the
instrument is operable again.
• After the instrument has been powered up, a reset
Code 7864 (general reset) must be entered in the
É
operation menu operation
If a measuring sensor unit with a different range has
been installed, the instrument must be calibrated to
the new measuring range according to the manual.
If the product structure of the instrument changes
after the exchange of a sensor assembly
(i.e. a different measuring range), an additional
modification type plate must be installed at the
housing.
