Attention:
Attention:
During the test, the value of the current loop does not follow the current process.
2.1.1 NORMAL OP
The value of the current loop follows the current process.
2.1.2 4.0mA
The value of the current loop no longer follows the current process.
It is set to the selected current value.
2.1.3 5.6mA
2.1.4 7.2mA
2.1.5 8.8mA
2.1.6 10.4mA
2.1.7 12.0mA
2.1.8 13.6mA
2.1.9 15.2mA
2.1.10 16.8mA
2.1.11 18.4mA
2.1.12 20.0mA

Testing the alarm current HIGH/LOW according to the settings in Fct. 3.10.
2.3 OUTPUT B1
2.3 OUTPUT B1
2.3 OUTPUT B1
2.3 OUTPUT B1
Testing the binary switching output B1 by changing its binary status.
Attention:
Attention:
Attention:
Attention:
During the test, the binary status does not correspond to the current process.
2.3.1 NORMAL OP
The binary status of the switching output corresponds to the current process.
2.3.2 OPEN
The binary status of the switching output no longer corresponds to the current process.
The selected status is tested.
2.3.3 CLOSED
2.4 OUTPUT B2
2.4 OUTPUT B2
2.4 OUTPUT B2
2.4 OUTPUT B2
Refer to 2.2 OUTPUT B1
2.4.1 NORMAL OP
2.4.2 OPEN
2.4.3 CLOSED
2.5 INPUT B3
2.5 INPUT B3
2.5 INPUT B3
2.5 INPUT B3
The current binary status of the binary input B3 is displayed. External switching of the
voltage applied to input B3 activates a change of the displayed binary status.
Note:
Note:
Note:
Note:
A reaction to the switching of the voltage applied to input B3 only occurs if the function B3
is activated (refer to Fct. 3.6).
