Connecting Loads Greater than 16 A or 3-Phase Machines
The installation may only be done by qualified electricians!
Loads up to 16 A can be switched directly via the relays in the Fabman Bridge. Machines with a load greater than 16 A or for 3-phase machines can be switched via an additional contactor.
The following wiring diagram shows the details:
Detecting equipment state:
idle or busy
The status of machines whose power supply is switched via the relays in the Fabman Bridge (single-phase machines up to max. 16A) can be determined via a built-in current sensor.
Also for machines which are switched via a contactor there is a possibility to determine the busy/idle status based on the current consumption with an additional current sensor (
SZC23-NO-AL-CH). A phase is fed through the current sensor, which in turn is connected to an input of the bridge. The sensitivity can be adjusted directly at the sensor.
The following wiring diagram shows how the current sensor is integrated:
