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 interter and a central
fan.
The output of the automatic start/stop device WCS are being converted
into an output signal which lays between 4-20 mA, 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 periode (per individual extraction
arm) and initial delay (for the entire system).
