7 - PROBLEMS, MAINTENANCE AND WARRANTY
ERRORS SIGNALLING:
The 2 displays are used as well to visualise
anomaly conditions of instrument functioning :
"- - - -"
= probe interruption.
"uuuu"
= the measured variable is gone under the probe limits.
"oooo"
= the measured variable is gone under the probe limits.
"u400"
= the temperature is gone under 400°C when it's used a
thermocouple "B" type. The regulation regularly proceeds considering PV
= 0°C.
"LbA"
= interruption of the regulation ring (see loop break alarm
function).
"noAt"
= autotuning interrupted by an anomaly (broken probe, etc.)
"toAt"
= autotuning not finished after 12 hours.
"Err EEPr"
= if the instrument is switched off before the parameters
programming is completed. Indicates an anomaly in the EEPROM memory
writing. To raise the blockade of this error situation just push the "LEFT"
key
.
All the anomaly conditions will de-active the regulation. These referred to
a bad functioning of the input sensor will switch the instrument into "OFF"
condition.
HOW TO CLEAN
:
We recommend to avoid abrasive cleaners or
containing solvents which could damage the instrument.
