After a cool-down phase, the Connection Boxes are started back up again automatically. The momentary status
can be read out via the PROFINET “Status” module.
Overall current monitoring for digital I/O voltage (U
Digital I/O
) has also been integrated into the ZAI02PN02. This
is necessary because current of up to 4 A can be made available at each port. However, the utilized power plug
has a rating of max. 9 A. This total may not be exceeded by the sum of all digital outputs. If the limit value is
nevertheless violated, the Connection Box is switched to an error status and all outputs are deactivated. The
Connection Box then has to be reset in order to start it back up again. Supply power must be briefly interrupted
to this end.
Looping through to the power out socket is not monitored in this case, and adherence to the specified maxi-
mum current values for the power in plug must be assured by the user.
