1 Full signal
2 Empty signal
3 Fault message
Check if all three switching conditions occur in the correct sequence
and the stated time period. If this is not the case, there is a fault in the
measuring system (see also the operating instructions manual of the
signal conditioning instrument). Keep in mind that connected instru-
ments are activated during the function test. By doing this, you can
check the correct function of the measuring system.
Note:
Keep in mind that the starting time t
A
of the voltage supply can extend
the time up to the first switching (e.g. VEGATOR 636: +1 s)
After releasing the button or after a brief line break.
