32 System Description
Fieldbus coupler or controller
Internal system supply module
Input current I
Activate all outputs when testing the current consumption!
If the electrical consumption of a power supply point for the 24 V system
supply exceeds 500 mA, then the cause may be an improperly
dimensioned node or a defect.
During the test, you must activate all outputs.
