IFM Electronic AT-interface AC2516 Notice De Montage page 12

Risk of destruction:
When a combined sensor (pin 2: analogue output, pin 4: 24 V
output) is connected ensure that the switching output cannot
switch. To do so, set the combined sensor accordingly (e.g. by
selection of a switch point which cannot be reached or by the
configuration "NPN switching").
Current measurement AC2516, AC2566
For all the following wiring diagrams the indicated pin connection
refers to the analogue module.
When an external link between pin 3 and pin 4 is used, the internal
link can be deactivated by resetting the parameter bit P0!
The internal link (pin 3 and pin 4) must be activated via the para-
meter bit P0.
