2.2.1 Sender/receiver unit
The sender/receiver unit contains the optical and electronic assemblies to send and
receive the light beam as well as to process and evaluate the signals. An RS485 interface
is available for service purposes. Clean air to cool the device and keep the optical surfaces
clean is fed via a purge air connection.
The sender/receiver unit is fastened to the duct with a flange with tube ( see “Device
components DUSTHUNTER SB30M”, page 14 ).

The current device state (operation/failure, maintenance/maintenance request) is
signaled on the rear side of the enclosure (green = operation, red = failure, yellow =
maintenance).
