Coding
To avoid mixing up the various signal condi-
tioning instruments, the plug-in socket is
provided with pins and the signal condi-
tioning instrument with appropriate gaps
(mechanical coding).
Instrument coding ensures (with differently
positioned coded pins) that the various sig-
nal conditioning instruments are not inadvert-
ently swapped.
An Ex coding with fixed coded pin ensures
that non-Ex and Ex instruments are not inter-
changed.
The coding is part of the explosion protec-
tion: on VEGAMET 602 Ex the supplied
coded pins (instrument coded pin and Ex
coded pin) must be inserted by the operator
acc. to the table below.
