7.1 Simulation
For simulation of a certain filling, you can call
up the function "Simulation“ on the adjustment
module MINICOM, in the software program
VVO or on the signal conditioning instrument.
You simulate a vessel filling and thereby a
certain sensor current. Please note that con-
nected instruments, such as e.g. a PLC react
according to their adjustments and will prob-
ably activate alarms or system functions.
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.
7.2 Error codes
Error codes Removal
E013 No valid measured value Message is displayed during the warm-up phase
- Sensor in the warm-up 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 new software (service).
Message appears during a software update.
E040 Hardware failure/Electronics defec- Check all connection cables.
tive Transducer defective.
