The CB-WCS/15 is a control box that is used in central extraction systems with extraction arms, to connect max. 15 automatic start/stop devices WCS to the mains. It is used as an interface between a welding cable sensor, an automatic damper, a frequency inverter and a central fan.
The output of the automatic start/stop device WCS are being converted into an output signal which lays between 4-20mA, to arrange the extraction volume of the central fan by means of a frequency inverter. It is also possible to set the fan’s run-out period (per individual extraction arm) and initial delay (for the entire system).
