5.2
Warning input inactive
Each of inputs 2 to 6 (terminals DE2 to DE6) can be programmed as inactive warning inputs. This means:
If the "+" and "-" poles of the electrical inputs are open (not connected electrically),

the message "8" is entered in the momentary status for the relevant input.

the message "8" is entered in the status register for the relevant input,

"W" flashes in the display.
When the pole of the input terminal is connected, the message will disappear from the momentary status.
Until the status register is cleared by the user the message and the "W" in the display will remain
permanently (unless another warning is generated).
The status message can then be used, for example to create an archive entry or to switch an output.
A special "Warning input inactive" application is the tamper detector for a reed contact pulse generator.
To program an input as an inactive warning input, send the relevant parameter files from the following to the
EK280 using the parameterization program "enSuite" (see chapter 3.6 "Send parameter file", page 17):

EK280 - Input 2 = Warning signal not active (*)

EK280 - Input 3 = Warning signal not active (*)

EK280 - Input 4 = Warning signal not active (*)

EK280 - Input 5 = Warning signal not active (*)

EK280 - Input 6 = Warning signal not active (*)
5.3
Information input active
Each of inputs 2 to 6 (terminals DE2 to DE6) can be programmed as active information inputs. This means:
When the input "+" and "-" are electrically connected, the message "13" is entered in the momentary status
of the relevant input.
The status message can then be used, for example to create an archive entry or to switch an output.
To program an input as an active information input, send the relevant parameter files from the following to
the EK280 using the parameterization program "enSuite" (see chapter 3.6 "Send parameter file", page 17):

EK280 - Input 2 = Message signal active (*)

EK280 - Input 3 = Message signal active (*)

EK280 - Input 4 = Message signal active (*)

EK280 - Input 5 = Message signal active (*)

EK280 - Input 6 = Message signal active (*)
5.4
Information input inactive
Each of inputs 2 to 6 (terminals DE2 to DE6) can be programmed as inactive information inputs. This means:
When the input "+" and "-" are open (not electrically connected), the message "13" is entered in the
momentary status of the relevant input.
The status message can then be used, for example to create an archive entry or to switch an output.
To program an input as an active information input, send the relevant parameter files from the following to
the EK280 using the parameterization program "enSuite" (see chapter 3.6 "Send parameter file", page 17):

EK280 - Input 2 = Message signal not active (*)

EK280 - Input 3 = Message signal not active (*)

EK280 - Input 4 = Message signal not active (*)

EK280 - Input 5 = Message signal not active (*)

EK280 - Input 6 = Message signal not active (*)
