Status LEDs
Each connector has two status LEDs for signal inputs and outputs.
LED "R/E" (left)
The LED "R/E" signals the status of the analog input and analog output. In the event of an error, the LED lights up red.
Check the "Error" status bit of the corresponding input to determine whether the error occurred at the input or at the output.
LED "R/E" | Status bit | Meaning |
|---|---|---|
off | x | The analog output is disabled. You can activate the analog output by not setting the output signal range to "disabled". |
green | x | The analog output is enabled. |
red | 1 | The measured value of the analog input is outside of the error thresholds. |
red | 0 | EPP4304-1002: The analog output cannot maintain the voltage. EPP4314-1002: The analog output cannot drive the specified current. See chapter Diagnosis. |
x = no meaning
LED "DI" (right)
LED "DI" indicates the status of the digital input. It lights green when the digital input detects a high level.
