9.11 Analogue inputs
A setpoint in the form of an analogue current or voltage signal can be provided by
connection to the socket "Temp.-Signal" 52 S (see Item 9.10).
By pressing the key
in the SHIFT mode the display shows
L
1
ANALOGUE INP/OUTP

INP = 0 OFF = 1_
Pressing 0
selects the configuration and scaling of a setpoint input.
The display shows
L

ANALOG INP. OFF = 0
L
2
ON = 1 CONF = 2_
Input 1
switches in a previously configured input as setpoint, and L
2
shows at the
right end A, indicating that the setpoint is determined by the analogue input. This
condition remains stored in case of a fault or after the power is switched off.
Input 0
switches the setpoint back to the setpoint source I internal, i.e. key input.
Scaling takes place interactively by applying the voltage and current values
corresponding to the appropriate temperature range limits to the appropriate input.
For pin connections for voltage or current input on socket 52 S see Item 9.10. This
method compensates various scaling errors, e.g. also those of the sources connected.
Pressing 2
configures and scales the setpoint input.
The display shows

U = 0 I = 1
Select a voltage range with 0
. Voltages in the range 0...10.5 V can be handled.
A current range is selected with 1 . Currents in the range 0...22 mA can be
handled.
