Check operating voltage
Electronics de-
fective
Press the characteristic reversal
switch. If the instrument then changes
the mode, the vibrating element may
be covered with buildup or mechani-
cally damaged. Should the switching
function in the correct mode still be
faulty, return the instrument for repair.
Push the characteristic reversal
switch. If the instrument then does
not change the mode, the electronics
module may be defective. Exchange
the electronics module.
Unfavourable in-
stallation location
Mount the instrument at a location in
the vessel where no dead zones or air
bubbles can form.
Buildup on the vi-
brating element
Check the vibrating element and
the sensor if there is buildup and re-
move it.
Wrong character-
istic selected
Set the correct characteristics on the
characteristics reversal switch (over-
flow protection, dry run protection).
Wiring should be carried out accord-
ing to the quiescent current principle.

Check if the vibrating element is dam-
aged or extremely corroded.

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.
7.3 Exchanging the electronics
If the electronics module is defective, it can be replaced by the user.
In Ex applications only an electronics module with respective Ex ap-
proval may be used.
You find all information to the electronics exchange in the operating
instructions of the new electronics module.
In general, all electronics modules of series SW60 can be inter-
changed. If you want to use an electronics module with a different
signal output, you carry out the complete setup. You find the neces-
sary, suitable operating instruction on our homepage.
