8 Causes of faults and remedies
8.1 Error and over-range messages (I/O communication port)
In order that messages can be transmitted via the I/O communication port to the master,
the auxiliary outputs 1-7 reserved there must be (see "Input Data Format", byte 3
page 53) preconfigured with the appropriate functions (see "Auxiliary Outputs 1 - 7"
page 63). To obtain the full range of messages, it is therefore advisable to distribute all
the possible functions on an auxiliary output.
Error
Cause
Remedy
Auxiliary output set
for "Error" function
- Memory area in internal
EEPROM defective
Possibly shut-off measuring system voltage then
switch on again. If the error recurs despite this
measure, the measuring system must be replaced.
Auxiliary outputs set
for the functions
"Operating range"
and "Safety range"
The switching points
programmed for the
operating and safety
range were exceeded.
These messages are not error messages, but simply
over-range messages. The use of these functions and
the associated responses to violation of the set limits
are regulated by the operator.
8.2 Parameterization errors
If an error occurs during parameter programming or in the READ/WRITE processes of
the internal EEPROM, an error occurring can be read in two ways:
 In "Assembly Class" programming, the measuring system automatically
returns an error status (the last two bytes), as well as the programmed values
to the master (see page 55 onwards).
 If programming is undertaken with the "Parameter Class", an error status of 2
bytes is sent to the master (see page 57 onwards) through the GET DATA-
CHECK command.
The possible errors and their avoidance are described as follows:

Remedy
Low Byte

Error reading data
Memory area in the
EEPROM is defective
If the error occurs during further command
execution, the measuring system must be replaced.

Error writing data
Memory area in the
EEPROM is defective
If the error occurs during further command
execution, the measuring system must be replaced.
