Error
Cause
Rectification
E013
no measured value available Sensor in boot phase
Sensor does not find an echo, e.g. due to faulty installation
or wrong parameter adjustment
E017
Adjustment span too small
Carry out a fresh adjustment and increase the distance be-
tween min. and max. adjustment
E036
no operable sensor software Carry out a software update or send instrument for repair
E041, E042, E043 Hardware error, electronics
defective
Exchange the instrument or send it in for repair
Depending on the reason for the fault and the measures taken, the
steps described in chapter "
Set up
" may have to be carried out again.
8.3 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
In Ex applications, only instruments and electronics modules with ap-
propriate Ex approval may be used.
If there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.
The new electronics module must be loaded with the settings of the
sensor. These are the options:
•
At the factory by VEGA
•
Or on site by the user
In both cases, the sensor serial number is necessary. The serial num-
bers are stated on the type label of the instrument, inside the housing
or on the delivery note.
Information:
When loading on site, the order data must first be downloaded from
the Internet (see operating instructions manual "
Electronics module
").
The electronics modules are adapted to the respective sensor and
distinguish also in the signal output or power supply.
8.4 Software update
The following components are required to update the instrument
software:
•
Instrument
•
Voltage supply
•
Interface adapter VEGACONNECT
•
PC with PACTware
•
Current instrument software as file
