Communication interfaces: Setting and function
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 a electric 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
parameterisable threshold can be optionally activated (see setpoint sensor configur-
ation).
Setpoint sensor configuration
NOTICE
When an external signal is used at the analogue input as setpoint source, the set-
point value must be paired to the analogue signal.
Open the editor's context menu for the affected setpoint for pairing.
24 V D power supply at the analogue input
NOTICE
The 24 V DC power supply is only available once the analogue input AI1, AI2, AI3 or
AI4 has been configured for a type of use and a signal type.
The use of an external signal at the analogue input as setpoint source requires pairing
of the setpoint value to the analogue signal:
In the "Settings" menu , select
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,...).
