along with the DC 24V-NS supply voltage.
BM 143-DESINA FO and BM 143-DESINA RS485 status display
The ET 200X-DESINA has two LEDs per channel (X1 to X8) 2 LEDs for status
indication:
”Yellow” LED (for digital input or output, pin 4)
The LED is yellow when the input or output is active.
LED ”red/yellow” (for pin 2 input functionality, see Table 5-1)
The LED is red when
– the functional input is parameterized as a diagnostics input for DESINA and
– a DESINA fault (status ”0”) is registered for the sensor/actuator.
The LED is yellow when
– the functional input is parameterized as an input with NC function and
– The status of the sensor connected to the input is non-switched (”1”).
