Electro-sensitive protective equipment
EFI connections
The UE 440/470 has two EFI connections for secure SICK device communication. You can
connect protective devices, which also have EFI connections (e.g. S 3000 or C 4000
Standard/Advanced), to these connections. The UE 440/470 can communicate with the
connected protective devices via the EFI interface (evaluate/transfer status information).
You configure whether you connect a protective device (e.g. S 3000 or C 4000) at both EFI
inputs and the status information which is accepted from the protective device and the
information which is transferred to the protective device. You can, for example...
$
accept the information from the protective device via the protective fields.
$
transfer the status of an operating mode selector switch connected to the UE 440/470
to the protective device. In this case, a different operating mode is switched to when
switching occurs, both with the UE 440/470 and the connected protective device.
$
transfer the status of a Teach-in key-operated switch connected to the UE 440/470 to a
C 4000.
The status information which can be accepted from the protective device or transferred to
it depends on the respective protective device (e.g. S 3000 or C 4000).
When transferring the status of an operating mode selector switch to a device connected
via EFI, the same number of operating modes must be configured there.
The connection of the C4000 Sender via EFI is not allowed.
When determining the safety distance of the protective devices, take the response
times of the OSSDs into consideration!
If the OSSD status of a connected protective device is accepted via EFI and used in the
safety controller to switch off their OSSDs, the response time of the OSSDs of the safety
controller increases due to the transfer of the OSSD status via EFI. This increases the
required safety distance S of the safety device(s) (see also Chapter 11.1 "Response times
of OSSDs A and B" on Page 86).
Take into account a Lockout condition of the EFI device when integrating the status
information!
If the EFI Status Information is processed by the UE440/UE470, please take into account
that the OSSDs of the UE440/470 can be active even though the EFI device is in Lockout.
Make sure that the BIT information „IO-Error-Status“ is processed as well.
