Chapter 8 Configuration
– Are there other reflective objects in the immediate vicinity that could interfere
with the system (e.g. reflective strips on safety clothing, packaging film, etc.)?
Remove the cause.
Perform teach-in again.
Internal restart interlock The configuration of the restart interlock is defined by the wiring that is in place during
the first or last teach-in process performed.
How to activate the internal restart interlock:
Make the electrical connections for the reset button (see “Connecting the SC300” on
page 28).
Switch on the SC300.
Perform a teach-in procedure.
If there is no signal on the Reset/restart input, then the safety camera system will activate
the internal restart interlock and save this configuration in the device. The device is now
waiting for the reset button to be pressed.
Check the effectiveness of the protective device as described in “Test notes” on page 38.
How to deactivate the internal restart interlock:
Permanently connect the
Reset/restart input to 24V (“Connecting the SC300” on
page 28).
Switch on the SC300.
Perform a teach-in procedure.
If 24V are present on the Reset/restart input, the safety camera system will deactivate the
internal restart interlock and save this configuration in the device.
Check the effectiveness of the protective device as described in “Test notes” on page 38.
External device monitoring In the default delivery status, the external device monitoring is deactivated.
How to activate the external device monitoring:
Make the electrical connections (“Connecting the SC300” on page 28).
Switch on the SC300.
Perform a teach-in procedure.
If the contacts to be monitored are connected to the external device monitoring (EDM)
input, then the safety camera system will activate the external device monitoring and save
this configuration in the device.
Check the effectiveness of the protective device as described in “Test notes” on page 38.
How to deactivate the external device monitoring:
Permanently connect the
External device monitoring (EDM) input to 0V (“Connecting
the SC300” on page 28).
Switch on the SC300.
Perform a teach-in procedure.
The external device monitoring will remain deactivated without
teach-in.
If you place the system in operation after connecting the
contacts to the external device monitoring (EDM) input without
teach-in, then the external device monitoring will remain
deactivated. The system can therefore switch to green despite
faulty contactors.
