EL3182
LEDs
LED | Color | Meaning | |
|---|---|---|---|
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 firmware updates of the terminal | ||
flashing | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set | ||
single flash | State of the EtherCAT State Machine: SAFEOP = verification of the Sync-Managers channels and the distributed clocks. | ||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | ||
Error | red | EtherCAT communication error | |
Error 1/ 2 | red | Fault indication for broken wire and if the measuring range for the respective channel 1/ 2 is exceeded (under- or overrun) | |
HART 1/ 2 | green | off | No HART communication |
on | HART communication active | ||
HART Error | red | HART communication error | |
EL3182 connection
Terminal point | Description | |
|---|---|---|
Designation | No. | |
I1 | 1 | Input channel 1 |
Uv1 | 2 | Sensor supply (internal connected with terminal point 6) |
GND | 3 | GND (internal connected with terminal point 7) |
S | 4 | Shield (internal connected with terminal point 8) |
I2 | 5 | Input channel 2 |
Uv2 | 6 | Sensor supply (internal connected with terminal point 2) |
GND | 7 | GND (internal connected with terminal point 3) |
S | 8 | Shield (internal connected with terminal point 4) |
Note: Externally powered sensors can be integrated as follows:
Connect (+)sensor to I1/ I2 and (-)sensor to GND. Uv1/ Uv2 are thus not used for the sensor power supply.
The EL6184 is designed for this type of connection – it is only intended to integrate externally powered sensors (functionality limited to reading out the HART values).
