Commissioning
6.2
Technical commissioning
6.2.1
Sequence for commissioning sub-systems
When commissioning the entire system, you must prevent faults in the sub-systems by
following a specialised sequence for commissioning.
First commission the devices at the EFI connections and test their system behaviour.
Do not commission the EFI gateway until the behaviour of the sub-systems is safe and
as required.
6.2.2
System self-check after switching on
The EFI gateway carries out the following steps automatically immediately after the power
supply is switched on:
Internal self-test
Loading of the saved configuration
Check whether the loaded configuration is suitable for the connected devices
The system does not start up if the steps described above could not be carried out
successfully. In the event of a fault or error, one or more displays of the EFI gateway
display
Red
and the EFI gateway transfers only fail-safe values (see chapter 8
28 on).
6.2.3
Full approval of the EFI gateway
You may only commission the system if full approval of the EFI gateway was successful.
Full approval of the EFI gateway may only be performed by professionals trained
accordingly.
The full approval includes the following items to be checked:
Check the devices connected to the EFI connections in accordance with the test notes
from the accompanying operating instructions.
Clearly mark all connection cables and connectors at the EFI gateway. Since the EFI
gateway has several connections of the same design, you must ensure that loosened
connection cables are not connected back to the wrong connection.
Check the configuration of the EFI gateway. Test the signal paths and the correct
inclusion in the safety program of the FPLC.
Check the correct data transfer from the devices at the EFI connections to the (F)PLC
and vice versa.
Check the FPLC program.
Carry out a complete verification of the safety functions of the system.
Completely document the configuration of the system, the individual devices, the (F)PLC
program and the result of the safety check.
