PRODUCT DESCRIPTION 2
2.2.1 Sender/receiver unit
The sender/receiver unit contains the optical and electronic subassemblies 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 “DUST-
HUNTER SB30 device components”, 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).
The enclosure with fitted sender/receiver unit can be swiveled to the side after the
CAMLOCK clips have been loosened. Optics, electronics and mechanical components can
then be easily accessed for maintenance work.
