Signalling of the Extraction and Filter System
Several options are available for monitoring dust vacuum and filter systems:
The operating statuses run and standby, the filter status, the filter warning and the error
types filter error, speed error and temperature error can be read off the INSPIRE
display. In addition, the error types are acoustically supported by a warning tone.
The filter warning signals as well as filter errors, speed errors and temperature errors
can be accessed externally via potential-free contacts at the INSPIRE interface as
standard. Application example: Integration of the extraction and filter system in a fully
automated process, e.g. laser welding with evaluation of the system status.
The dust vacuum signal module can be used.

Dust Vacuum Signal Module
In addition, the dust vacuum signal module can be used to ensure a clear acoustic and visual
status detection of the extraction and filter system. Application example: Use of the system as
a mobile welding-fume extraction system.
It signals the following statuses:

Monitoring of Fixed Hoses and Piping
In extraction elements, hoses and pipes which are mechanically connected to the extraction
and filter system and can only be released by the use of tools, the volume flow does not have
to be monitored separately when the extraction and filter system is designed as follows:
Minimum required volume flow when the filter saturation is reached (to be determined
by the operator) x 1.3 = required nominal volume flow.
Dimensioning of the diameter of pipes and hoses to a flow velocity of approx. 15m/s
(see also section “Use of Piping and Hoses“)

Monitoring the Extraction Capacity at the Extraction Location
For monitoring the extraction capacity at the extraction point when using not-permanently
affixed hoses and pipes, which can be released on one side, the use of an additional volume
flow monitoring system (see accessories catalog) is suggested. It should be mounted as
