Note:
All 10 sensor inputs
(z14␣ …␣ z32) are connected
(broken line).
Note:
- The connections d12␣ …␣ d16, d20␣ …␣ d24 as well as d28␣ …␣ d32
are connected.
- The connections z12 … z16, z20␣ …␣ z24 and z28␣ …␣ z32 are on
the same minus potential (broken line).
Each sensor input can be
switched passively as well as
actively.
