Checking the condition of the outputs
This function provides a simple overview of the conditions of all outputs of the
combination output module (see section 4.7).
For the relays, the displayed condition is open or closed.
For the current outputs, the current value present at the outputs is displayed.

Behavior of linked outputs
6.9.1 Behavior in case of error
For linked relay outputs or current outputs, you can determine the behavior of
the outputs in case of errors.
Depending on the use of the output, the behavior in case of errors is set in the
following menus:
Output
Frequency controller
Pulse-width output
Recorder
The specified behavior occurs with the following events or conditions:
The linked sensor does not provide any valid measured value
(display of Init, Error, "-----", or OFL)
Communication with the DIQ/S 281 is interrupted for more than 2 minutes.
The supply voltage for the DIQ/S 281 is too low.
In the function Recorder, the measured value of the linked sensor is outside
the range between Start value and End value.
Irrespective of the behavior in case of error that was defined, the following situ-
ations cause the conditions of the outputs to be frozen:
The linked sensor is in the maintenance condition
(display of Cal, Clean, or flashing measured value).
Communication with the DIQ/S 281 is temporarily interrupted. After an inter-
ruption of 2 minutes the output changes to the behavior defined for error.
The relay or current output automatically returns to its normal condition as soon
as all errors have been eliminated and all conditions that caused the freezing of
the outputs were eliminated.
