Due to safety and guarantee reasons repair work
beside the wiring must only be made by VEGA-staff.
In case of a defect please return the respective

5.4 Fault signal
The signal conditioning instrument and the
connected sensor are permanently monitored during
operation. During the parameter adjustments to
adjusted values are checked on plausibility. In both
cases fault signals can be caused by irregularities.
In case of failure an error code is indicared on the
display (only in the range indication of measured
values), the fail safe relay de-energizes, the failure
LED lights and the outputs react acc. to their control
condition.
The error codes are listed in section 5.5 on the
following pages.
The diagnosis info is transferred by means of a
current text indication.

Parameter adjustment
In the menu point "Failure mode" can be determined
separately for each measuring point how a
decreasing of the measuring range should trigger a
