9 Maintenance and fault rectification
VEGACAL 69 • Two-wire 4 … 20 mA/HART
31178-EN-200929
Error Cause Rectification
E013 no measured value avail-
able
•
Probe insulation damaged, short-circuit due to per-
meating, conductive medium
•
Exchange the instrument or send it in for repair
Shortcircuit in the probe,
e.g. because of moisture in
the housing
•
Remove the electronics module out of the probe and
check the resistor between the two marked plug con-
nections according to the figure in paragraph " Check
the resistance in the probe ".
•
There should be no contact between any of the con-
nections (high resistance)
•
If there is still a connection, exchange the instrument
or return it for repair
E017 Adjustment span too small Carry out a fresh adjustment and increase the distance
between min. and max. adjustment
E036 no operable sensor soft-
ware
Carry out a software update or send instrument for re-
pair
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.
9.3 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 order data 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 needed. The serial num-
bers are stated on the type label of the instrument or on the delivery
note.
Information:
When loading on site, the order data must first be downloaded from
the Internet (see operating instructions " Electronics module ").
The electronics modules are adapted to the respective sensor and
differ in their signal output or in their power supply. You can find a suit -
able electronics module in the following overview.
The oscillators differ only in their signal output and are suitable for all
series 60 sensors.
The following types are available:
•
CL-E60 H (4 … 20 mA/HART)
