Signal connection
Notice | |
Supply and connection of sensors and actuators to EtherCAT P Box modules The connected sensors and actuators must be supplied by an EtherCAT P Box. GNDS and GNDP from one of the M8 / M12 signal connections of an EtherCAT P Box must not be connected to the machine bed. |
 | Supply of externally powered sensors or actuators If the sensors and actuators cannot be supplied from the EtherCAT P Box, the supply of externally powered sensors and actuators must be electrically isolated. |
| EMC shield clamp Depending on the application it may be necessary to additionally attach the shield of the sensor cables at the signal inputs of the box with shield clamps ZB8513-0002. See Chapter: “Accessories”, section “Cables”. |
The actuator is connected via Output + and Output -. The actuator can optionally be operated/supplied with 24 VDC.
The ground potentials on pin 3 and pin 4 are electrically isolated. If the actuator requires a supply voltage and only has an earth connection, connect pin 3 and pin 4 with a jumper.
LED indicators - meanings
There is a green Run LED and a red Error LED for each channel. The green Run LED is lit when data are transferred to the D/A converter. The red Error LED indicates that there is an error (open circuit, measured value outside the range).
Correct function is indicated if the green Run LED is on and the red Error is off.
