8 Diagnostics and servicing
8.1

Maintenance

If the instrument is used correctly, no maintenance is required in
normal operation.
8.2

Asset Management function

The instrument supports the self-monitoring and diagnosis of the con-
nected sensor. Status or failure messages are displayed according to
the sensor via display and adjustment module, PACTware/DTM and
EDD.
You can find a detailed overview of this function in the operating
instructions of the respective sensor.
The following table shows the error codes and text messages of the
VEGADIS 82 and gives information on the cause and removal.
Reason
•
CRC error during self-
check
•
Short-circuit or sensor
current > 21 mA
•
Line break or sensor
current < 3.6 mA
•
Scaling span too small
•
Scaling value too high
•
EEPROM: CRC error
•
ROM: CRC error
•
Error of the RAM in the
internal data memory
•
Hardware error
8.3

Rectify faults

The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Rectification
•
Carry out a reset
•
Send instrument for repair
•
Check cable
