0805
0805 C.REQ.VAL 1
digital
Configuration required value 1
Possible settings: - digital - analog U 0-10V
- analog I 0-20mA - analog I 4-20mA
Digital
The internal required value 1 is used.
Setting in the main menu in Parameter 02 or parameter
[0820].
analog U=0 – 10V
The required value 1 is determined by the value of a voltage signal
(0 – 10V) connected to terminals X3/13- X3/14 (GND).
analog I=0 – 20mA
analog I=4 – 20mA
The required value 1 is determined by the value of a current signal
(4 – 20mA or 0 – 20mA) connected to terminals X3/18- X3/17
(GND).
Notice: If the incoming current signal drops below 4mA (4-20mA
setting), a warning message is shown on the display. If the failure is
still active after 20 seconds, an error message will be shown.
The changeover between the 1
st and the 2 nd required value can be done either internally or
externally via the digital inputs. With the following parameters the source of the required
values and the change over can be configured.
0810
0810 C.REQ.VAL 2
OFF
Configuration required value 2
Possible settings: - OFF - digital - analog U 0-10V
- analog I 0-20mA - analog I 4-20mA
OFF Required value 2 is not used.
digital
The internal required value 2 is used.
Setting in the main menu in Parameter 02 or Parameter
[0825].
analog U 0 – 10V
The required value 2 is determined by the value of a voltage
signal (0 – 10V) connected to terminals X3/15- X3/16 (GND).
analog I 0 – 20mA
analog I 4 – 20mA
The required value 2 is determined by the value of a current
signal (4 – 20mA or 0 – 20mA) connected to terminals
X3/23- X3/22 (GND).
Notice: If the incoming current signal falls below 4mA (4-20mA
setting), a warning message is shown on the display. If the failure is
still active after 20 seconds, an error message will be shown.
