6.1 Simulation
To simulate a certain filling level, you can call
up the function “Simulation” in the adjustment
module MINICOM, in the adjustment software
PACT
ware TM or in the HART ® handheld.
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
probably activate alarms or system func-
tions. One hour after the last simulation ad-
justment, the sensor returns automatically to
standard operating mode.
5.2 Error codes
Display Meaning 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, a false echo storage
must be made with the adjustment module
MINICOM in the menu “sensor optimisation” or
better, with the PC and VVO.
If the message still remains, carry out a new
adjustment.
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 - Sensor must be programmed with new
run software (service)
- Message appears during a software update.
E040 Hardware failure/Electronics Check all connection cables.
