Replacing the Electronic Insert
Switch off all sources of power to the Nivocompact
• Remove the electrical connections to the electronic insert
• Remove the central screw in the electronic insert
• Lift out the electronic insert from the housing using the handle
• Push the new electronic insert carefully into the plug in the housing
• Tighten the central screw
• Connect up the electrical wires
• Set the switching delay
• Select the same fail-safe mode as it was for the old electronic insert.
• Turn on the power supply
• Fill and empty the silo by the installation point of the probe and check the
switching of the instrument.
This is extremely important with bulk solids having low dielectric constants
or with critical installations.
• If required: Carry out a capacitance calibration.
Returning Parts for Repair
If a Nivocompact FTC 731 cannot be repaired and needs to be sent back to
Endress+Hauser, then please note the following:
Remove all material residue attached to the probe.
This is especially important as the material may be of a dangerous nature,
e.g. corrosive, poisonous, carcinogenic, radioactive etc.
Please return parts only after they have been thoroughly cleaned of
dangerous materials. Check in particular scratches and the possibility of
diffusion through plastic material.
When returning the probe, please state exactly the material in which it was
used and its chacteristics.
A brief description of the error will also help us to diagnose the reason for it
and at the same time lower your costs.
Thank you for your cooperation.
