7.1 Simulation
To simulate 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 or PC
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.
7.2 Error codes
Error codes Rectifying measure
E013 No valid measured value Message is displayed during warm-up phase
- Sensor in the warm-up phase
- Loss of the useful echo
If the message remains, an echo treatment and
false echo reduction must be carried out in the
menu "Sensor optimisation“.
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 must have a new software (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 HART ® handheld
If you call up the simulation mode with the
HART
® handheld, the sensor only returns to
operating mode after quitting 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.
