Diagnosis
9 Diagnosis
9.1 Maintenance
The instrument is maintenance-free.
9.2 Simulation
Note
With activated simulation, the entire display
flashes. The measured data delivered by the
sensors are not released for processing -
you should, therefore, quit this menu item as
soon as possible. After 15 minutes, there is
an automatic reset to meas. value indication.
9.3 Fault signal
The signal conditioning instrument and the
connected sensor are continuously moni-
tored during operation. During parameter
adjustment, the set values are checked for
plausibility. In both cases, a fault signal can
be triggered by irregularities.
In case of failure, an error code is displayed
(only within the meas. value indication), the
fail safe relay deenergises, the signal lamp
lights and the outputs react according to their
preadjusted control behaviour.
The error codes are listed in section "9.5
Error codes“ on the following pages.
The diagnosis info is transmitted as a running
text page.
Configuration
For each individual measurement loop, you
can determine if a fault signal should be trig-
gered or not. See menu range "Configuration
measurement loop“ menu item "Fault signal“.
Parameter adjustment
In the menu item "Failure mode“, you can
determine individually for each measurement
loop whether and how a measuring range
overrun should trigger a fault signal.
9.4 Repair
For safety and warranty reasons, repair on
the instrument must only be carried out by
VEGA staff.
In case of defect, please return the impaired
instrument with a short description of the fault
to our repair department.
