SITRANS LR460 – INSTRUCTION MANUAL
Check calibration settings of
device. Ensure settings for
High Calibration Point and
Low Calibration Point are
different.
Return the device to the
factory.
Lower the ambient
temperature enough to cool
the device.
Fault code will persist until a
manual reset is performed
using PDM or the LCD
interface.
Check configuration for
AIFB1. Ensure that Upper
Value and Lower Value
(Process Value Scale) are not
the same.
Check configuration for
AIFB2. Ensure that Upper
Value and Lower Value
(Process Value Scale) are not
the same.
Perform calibration.
Perform calibration.
If fault persists, return device
to manufacturer
If fault persists, return device
to manufacturer.
If fault persists, return device
to manufacturer.
