Fig.37: EL8601-8411 - LEDsNo. | Name | Color | Meaning | |
|---|---|---|---|---|
1 | Error | red | off | No error |
on | Error | |||
2 | DI/ENC A/CNT Clk | green | off | Signal voltage "0" (-3 V ... 5 V) at the corresponding input |
3 | DI/ENC B/CNT Dir | |||
4 | DI/Latch/Thr. Out/DO | on | Signal voltage "1" (11 V ... 30 V) at the corresponding input/output | |
5 | DI/Gate/DO | |||
6 | PWM 1/ DO | green | Signal at PWM 1 / DO - output | |
7 | AI | green | Signal at analog input (AI) | |
8 | Error AI | red | Fault indication for wire break and if the measuring range for the analog input is exceeded (see chapter "Measuring ranges and scaling type"). | |
9 | RUN | green | This LED indicates the terminal's operating state: | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal | |||
flashing uniformly | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default settings set | |||
flashing slowly | State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. | |||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | |||
flashing rapidly | State of the EtherCAT State Machine: BOOTSTRAP = function for Firmware updates of the terminal | |||
10 | DI 1 | green | off | Signal voltage "0" (-3 V ... 5 V) at the corresponding input |
11 | DI 2 | |||
12 | DI 3 | on | Signal voltage "1" (11 V ... 30 V) at the corresponding input | |
13 | DI 4 | |||
14 | PWM 2 / DO | green | Signal at PWM 2 / DO output | |
15 | AO | green | Signal at analog output (AO) | |
16 | Error AO | red | Error at analog output: | |
 | Overcurrent protection of the 20 mA inputs The current inputs are protected against damage due to overcurrent by an internal current limiter. Currents > 30 mA can occur.
