EL5131 - LEDs
No. | Name | Color | Description | |
---|---|---|---|---|
1 | A1 | green, red | green: indicates TRUE level red: There is a wire break at the respective input. Diagnosis is only possible if the following three conditions are met.
| |
2 | B1 | |||
3 | C1 | |||
4 | Status Input | red | Fault signal input from rotary encoder. Input is internally connected to 5 V via a pull-up resistance. The encoder output must actively pull the signal against GND. | |
on | Output active at the encoder, a fault message is present at the encoder | |||
off | Output not active at the encoder; no fault message is present | |||
5 | Power Enc. | green | Operating voltage display for incremental encoder power supply | |
7 | Latch | green | is lit, if a signal (+24 V) is connected to the latch input | |
8 | Digital output 1 | green | is lit, if output 1 is set (+24 VDC) | |
9 | Run | green | This LED indicates the terminal's operating state: | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal or BOOTSTRAP = function for terminal firmware updates | |||
flashing | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default settings set | |||
single flash | State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. Outputs remain in safe state | |||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | |||
10 | Diag | red | Initialization process active or state of the EtherCAT State Machine: BOOT | |
15 | Gate/Latch | green | is lit if a signal (+24 V) is present at the gate/latch input | |
16 | Digital output 2 | green | is lit if output 2 is set (+24 VDC) |
