The changeover between 1
st
and the 2
nd
required value can be done internally or externally
via the digital inputs. With the following parameters the source of the required values and
the change over can be configured.
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 falls below 4mA, a warning
message is shown on the display. If the failure is still active after 20
seconds, an error message will be shown.
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).
Notic:
If the incoming current signal falls below 4mA, a warning
message is shown on the display. If the failure is still active after 20
seconds, an error message will be shown.
