D-R 290
The D−SK AE control electronics are electrically connected to the D−SK 290 MA fail-
safe shutter via a 6-core cable.
Do not make the electrical connection to the fail-safe shutter until the measuring
device has been installed!
In addition an F3 air flow sensor which is installed in the purge air infeed to the meas
uring device and which detects any failure of the purge air is connected to the D
−SK AE control electronics.
The 6-core cable (2 metre length supplied) to the fail-safe shutter and the cable to the
air flow sensor can be extended to 50 metres without problem (air flow sensor 3-core
cable with an overall screen).

After removing the cover screws (PG 7), install the air flow sensor in the opening
alongside the purge air connection for the measuring device so that the air flow pass
es through the transverse hole in the sensor. The red colour marking is an installation
aid and points away from the device towards the hose (air flow).
D-SK AE electrical connection
The electrical connection to the fail-safe shutter is made using a 20‑way terminal strip
in the D‑SK AE junction box as shown in the connection diagram).
