7.2 Commissioning and parameterization of the EL922x
with EtherCAT
To commission the EL922x with EtherCAT, proceed as follows:
1. Mounting
Mount the EL922x as described in the chapter Mounting and wiring [
}
31]
2. Terminal wiring
Power supply
Connect the 24 V DC power supply to the respective terminal contacts. Supply 24 V DC to terminal
contacts 2 or 6 and 0 V to terminal contacts 3 or 7. The maximum permissible input current, in case of
forwarding the input voltage, can be found in the technical data.
(Input current = forwarding c current of the own terminal)
Protected output
Connect output 1 to terminal point 5 and/or use the power contact. Output 2 is tapped via terminal
point 8 (no further power contact is available here)
Digital inputs
Connect the digital inputs (for switching and resetting the outputs) to terminal point 1 for switching out-
put 1 and terminal point 4 for switching output 2. A negative edge of 24 V DC is required.
