6 - PROBLEMS, MAINTENANCE AND GUARANTEE
6.1 - ERROR SIGNALLING
Push key “P”Possible anomaly of
the EEPROM memory
ErEP
Check the working of probe
and actuator and swap the
instrument to (rEG) control
Loop control
interrupted
(Loop break alarm)
LbA
Check the functioning of
probe and actuator and try
to repeat the auto-tuning.
Auto-tuning not
finished within 12
hours
noAt
Push key “P” in order to
make the error message
disappear. Once the error
has been found, try to
repeat the auto-tuning.
Auto-tuning not
possible because the
process value is too
higher or too lower
E
r
A
t
The measured
variable is over the
probe’s limits
(over-range)
oooo
The measured
variable is under the
probe’s limits
(under-range)
uuuu
Verify the correct
connection between probe
and instrument and then
verify the correct
functioning of the probe
Probe interrupted
- - - -
A
ction ReasonErro
r
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 - GUARANTEE AND REPAIRS
The instrument is under warranty against manufacturing flaws or
faulty material, that are found within 12 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
