5.1 Replacement of electronics
Replacing the electronics modules is no
problem, since they are subject to narrow
limits of variation and require no adaptation to
other sensor (mechanical or electrical) com-
ponents.
Before removing the electronics module, the
positions of the conductance switch, the
mode switches and the integration switch
should be noted. Set the new electronics
module to the same values. A fresh adjust-
ment to the medium is unnecessary. As soon
as you insert the sensor electronics, the
VEGAKON is ready for operation.
5.2 Simulation of switching func-
tions
With the switch positions "Test max." and "Test
min.", full immersion (max.) or empty immer-
sion (min.) can be simulated. It is not possi-
ble to move the medium. The level of the
medium does not have to be raised or low-
ered. This enables you to check the re-
sponse of the signalling and switching
systems which are controlled by VEGAKON
66. Certain parts of the sensor electronics
are also checked during the test.
