6 Diagnosis
6.1 Simulation
To simulate a certain filling, you can call up
the function "Simulation" on the adjustment
module MINICOM or in the software program
VVO.
With this function, you simulate a real vessel
filling level. Please note that connected instru-
ments, such as e.g. a PLC, react according
to their adjustments and will probably acti-
vate alarms or system functions.
6.2 Error codes
Error codes Corrective measure
E013 No valid measured value Message is displayed during the warm-up
- Sensor in the warm-up phase phase
- Loss of the useful echo If the message remains, a false echo storage
(with the adjustment software on the PC - see
"Echo curve" under "Sensor optimisation") must
be carried out together with a modification of
mounting location and orientation to achieve the
lowest possible false echo background.
E017 Adjustment span too small Carry out a readjustment.
Make sure that the difference between
min. and max. adjustment is at least 10 mm .
E036 Sensor software does not run Sensor requires a software update (service).
Message appears during a software update.
E040 Hardware failure/Electronics defec- Check all connection cables.
tive Transducer defective.
Contact our service department.
Simulation with VVO
If you start the simulation mode with the ad-
justment program VVO on the PC, the simu-
lated level is outputted until you quit the
simulation mode.
Simulation with MINICOM
If you start the simulation mode on the adjust-
ment module MINICOM, the sensor returns to
standard operating mode after one hour.
