6. Commissioning, operation
If the transmitter to be connected does not have the negative power terminal
on contact 2 and the positive power terminal is not on contact 1, then the
assignment of the A-IAI-1 angular connector and the external angular
connector must be matched accordingly. To do this, open the A-IAI-1 angular
connector and exchange the wires from contact 1 and contact 2, so that
these match the connection of the transmitter to be attached.
Now wire both contacts in the angular connector accordingly.
General information on changing the angular connector assignment
Lift out the coupling assembly using a screwdriver in the recess on the side.
Change the assignment in line with the instructions for the relevant input
signal.
Then snap the coupling assembly back into the cover. There are 4 different
output orientations to choose from - each at 90° to each other. Attach the
angular connector and screw the connector together using the long bolt
delivered with the unit (don't forget the seals).
In the angular connector, pin contact 2 is directly connected (1:1) with the
female contact. Between pin contact 1 (+) and female contact 1 (-) is the
A-IAI-1. Pin contact 3 and 4 are also connected 1:1 with the female connec-
tor.
