3.9.2 Usage of the auxiliary voltage
The universal transmitter DIQ/S 281 has a 24 V output (designation
HILFSSPANNUNG or AUXILIARY VOLTAGE on the terminal strip). You can
use this auxiliary voltage for the relay-controlled opening of the valve in a DIQ/
CHV valve module for the compressed air-driven sensor cleaning function. To
do so, you have to connect the auxiliary voltage output, a free relay contact and
the valve connection in the DIQ/CHV in series. Bridge a terminal of the auxiliary
voltage output with a terminal of a relay output and run a control line from the
remaining terminals to the valve module.
The auxiliary voltage must not be used for other purposes.

Run the bridge below the divider so the bridge does not bump against the circuit
board in the lid when the enclosure is closed.
WARNING
No free wires are allowed to project into the housing. Oth-
erwise, there is a danger that areas safe to contact could
come into contact with dangerous voltages. This could re-
sult in life threatening electric shock when working with
the universal transmitter DIQ/S 281. Always cut off any
wires that are not in use as closely as possible to the cable
gland.
