LD292 - Operation and Maintenance Instruction Manual
4.2
If the problem is not presented in the table above follow the Note below:
NOTE
The Factory Init should be tried as a last option to recover the equipment control when the
equipment presents some problem related to the function blocks or the communication.
This
operation must only be carried out by authorized technical personnel and with the
process offline, since the equipment will be configured with standard and factory data.
This procedure resets all the configurations run on the equipment, after which a partial download
should be performed.
Two magnetic tools should be used to this efect,. On the equipment, withdraw the nut that fixes
the identification tag on the top of the housing, so that access is gained to the "S" and "Z" holes.
The operations to follow are:
1) Switch off the equipment, insert the magnetic tools and keep them in the holes (the magnetic
end in the holes);
2) Feed the equipment;
3) As soon as Factory Init is shown on the display, take off the tools and wait for the "5" symbol
on the right upper corner of the display to unlit, thus indicating the end of the operation.
This procedure makes effective all the factory configuration and will eliminate eventual problems
with the function blocks or with the equipment communication.
