13.17 What error messages are there for measurement/the
process status, and how can I correct errors?
The messages in square brackets are shown on the display of the MP85A.
Message
Transducer error
[TransdErr]
ADC overflow
[ADC Ovfl]
Gross overflow
[Grv Ovfl]
Scaling error
[Scal.Err]
EEPROM error
Flash error
CAN bus error
MP85A
Cause
Amplifier overflow in
the MP85A
The A/D converter
has overflowed
The gross measured
value is outside the
measuring range
An incorrect scale
was specified
An error occurred
when reading out
the EEPROM of the
MP85A
An error occurred
when reading out
the flash EPROM.
An error has
occurred on the
CAN bus

Remedy
Check the connected transducer and the
type of connection (are sense leads con­
nected?). A displacement transducer may
be incorrectly positioned (core extended
too far), or the transducer or a cable may
be faulty.
This indicates a similar problem to a trans­
ducer error. The measurement signal may
be too large; check the measuring range.
This can happen if excessive tare loads are
present. The indicated net value plus tare
load adds up to the gross value.
Please check the entered values and see
FAQ "What are the limitations for (trans­
ducer) scaling?" on page 135.
This may be a one-off read error; please
repeat the process. If the error reoccurs,
please contact HBM Service or HBM
Support (see PME Assistant online help).

Support (see PME Assistant online help).
Check that the termination resistors are
present and whether a channel is faulty.
Then switch the devices back on. If this
does not help, connect the devices to the
CAN bus one at a time, to find out which
device is faulty.
