Fixed current value
Function The
Fixed current value
function can be used to test the operativeness of the
instruments connected to the outputs: output different current values to the out-
put and, while doing so, check the behavior of the connected instrument.
6.8 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.
6.9 Behavior of linked outputs

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:
Error events
The specified behavior occurs with the following events or conditions:
