Example setpoint sensor
The following signal types are available for the type of use "Setpoint sensor":
Setpoint sensor signal types:
0 ... 10 V: voltage range of 0 ... 10 V for transfer of setpoints.
2 ... 10 V: voltage range of 2 ... 10 V for transfer of setpoints. Cable break is detected for a voltage below 2 V.
0 ... 20 mA: electric current range of 0 ... 20 mA for transfer of setpoints.
4 ... 20 mA: electric current range of 4 ... 20 mA for transfer of setpoints. Cable break is detected for an elec-
tric current below 4 mA.
NOTICE
The substitute setpoint is adjusted in the event of cable break detection.
For the signal types "0 ... 10 V" and "0 ... 20 mA", a cable break detection with a parameteri-
zable threshold can be optionally activated (see setpoint sensor configuration).
Setpoint sensor configuration
NOTICE
When an external signal is used at the analog input as setpoint source, the setpoint value
must be paired to the analog signal.
Open the editor's context menu for the affected setpoint for coupling.
NOTICE
The 24 V DC power supply is only available once the analog input AI1 or AI2 has been config-
ured for a type of use and a signal type.
The use of an external signal at the analog input as setpoint source requires coupling of the setpoint value to
the analog signal:
In the "Settings" menu
1. "Set control mode".
Depending on the selected control mode, the setpoint editor displays the adjusted setpoint (setpoint
delivery head Δp-v, setpoint temperature T-c,...).
