b
Provide a sufficient suppressor circuit for all output contacts for capacitive and
inductive loads.
b
If the device does not respond when the supply voltage is connected (e.g. green
LED STATE does not light up), return the device to the manufacturer unopened.
NOTE
•
The supply voltage UB is reverse polarity protected.
•
A cross-circuit between 13/14 and 23/24 can be detected only by external clock‐
ing.
•
The application diagnostic output DIA and the sensor connections (H1a/H1b,
H2a/H2b, H3a/H3b and H4a/H4b) are not short-circuit protected.
•
The application diagnostic outputs 01 … 02 or 01 … 04 are short-circuit protected,
but are not overload-proof.
