- ERROR SIGNALLING
Error Reason Action
- - - -
Prob

connection between probe
and instrument and then
verify the correct
functioning of the probe
uuuu
Th

variable is under the
probe’s limits (under-
range)

Push key “P” in order to
make the error message
disappear. Once the error
has been found, try to
repeat the auto-tuning.

finished within 12
hours
Check the functioning of
probe and actuator and try
to repeat the auto-tuning.

Check the working of probe
and actuator and swap the
instrument to (rEG) control
ErEP

Push key “P”
In error conditions, the instrument provides an output power as
programmed on par. “OPE” and activates the desired alarms, if the
relative parameters “ALni” have been programmed = yES.
6.2 - CLEANING
We recommend cleaning of the instrument with a slightly wet cloth
using water and not abrasive cleaners or solvents which may
damage the instrument.
6.3 - WARRANTY AND REPAIRS
The instrument is under warranty against manufacturing flaws or
faulty material, that are found within 18 months from delivery date.
The guarantee is limited to repairs or to the replacement of the
instrument. The eventual opening of the housing, the violation of
the instrument or the improper use and installation of the product
will bring about the immediate withdrawal of the warranty’s effects.
In the event of a faulty instrument, either within the period of
warranty, or further to its expiry, please contact our sales
department to obtain authorisation for sending the instrument to
our company. The faulty product must be shipped to Ascon
Tecnologic with a detailed description of the faults found,
without any fees or charge for Ascon Tecnologic, except in the
event of alternative agreements.
