11.8 Connection to 0-10 V input (only possible for U)
The U can be equipped with an external provision with 0-10 volt control) (e.g. humidity sensor or CO
2
sensor). This external
provision can be connected to pins no. 3 and no. 4 of 9-pole connector X15; this 9-pole connector is directly accessible at the rear of
the top without having to dismount the display cover (see also §11.1).
Connections X15-3 and X15-4 are set as standard as 0 - 10 V input; it is activated as standard. Parameter 21 is set “1” ex factory.
When the connected provision is active, the display shows the message V2. The minimum and maximum voltage for connected pro
-
visions can be set between 0 and 10 volt with parameter 22 (minimum voltage) and 23 (maximum voltage). The minimum voltage for
parameter 22 cannot be set higher than the voltage set for parameter 23; the maximum voltage for parameter 23 cannot be set higher
than the voltage set for parameter 22.

sensor.
Connected provision has its own
power supply.
D = Display U (text “V2” appears
when the provision is active on input
2.)
If connection X15-1 and X15-2 are programmed as second 0-10 V input, parameters 15, 16 and 17 can be used to modify the various
situations the same as for the standard 0-10 V input. When the provision is active on the optional second 0-10 V input, the display
shows the text “V1”.
If a second 0-10 V input is required, if necessary connections no. 1 and no. 2 of the 9-pole connector X15, standard preprogram
-
med as switch contact, can be reprogrammed to a second input 0-10 V. Modifying parameter 15 from “0” to “1” makes this input into
a proportional 0-10 V input. When using two 0 - 10 V inputs, the 0 - 10 V input with the highest flow rate always takes precedence.
Ex factory activated 0 - 10 V input (when active, the display shows the text “V2”)
