Error Cause Rectification
Wrong mode selected Set the correct mode on the mode switch (overflow
protection, dry run protection). Wiring should be carried
out according to the quiescent current principle.
Signal lamp flashes red Error on the vibrating ele-
ment Check if the vibrating element is damage or extremely
corroded.
Interference on the elect-
ronics module Exchanging the electronics module
instrument 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.
7 .3 Exchanging the electronics module
In general, all electronics modules of series VB60 can be inter-
changed. If you want to use an electronics module with a different
signal output, you can download the corresponding operating
instructions manual from our homepage under Downloads.
With EEx d instruments, the housing cover may only be opened if there
is no explosive atmosphere present.
Proceed as follows:
1 Switch off power supply
2 Unscrew the housing cover
3 Lift the opening levers of the terminals with a screwdriver
4 Pull the connection cables out of the terminals
5 Loosen the two screws with a screw driver (Torx size T10 or slot 4)
