ET 200X Distributed I/O Device
EWA 4NEB 780601602-06
DC 24V-S LED
The DC 24V-S LED is on when the switched DC 24V-S supply voltage is available
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”).
Status display of the BM 141 DI 8 DC 24V ECOFAST
In the case of the BM 141 DI 8 DC 24V ECOFAST basic module there is one
LED for each channel (X1 to X8) for status display:
Green LED (for digital input)
The LED is green when the input is active.
Status display of the BM 141 DI 8 DC 24V ECOFAST DIAG
In the case of the BM 141 DI 8 DC 24V ECOFAST DIAG basic module there
are two LEDs for each channel (X1 to X8) for status display:
Green LED
The LED is green when the input is active.
Red LED
The LED is red if there is a fault on the channel:
– Short circuit of the 24 V sensor power supply
– Digital input wire break
