Locking the internal teach-in key In the default delivery status the internal teach-in key is unlocked, i.e. it can be used. To
permit remote teach-in and/or to help protect the configuration, you can connect an
external key-operated pushbutton for teach-in and lock the internal teach-in key.
How to lock the internal teach-in key:
Connect an external key-operated pushbutton for teach-In (“Connecting the SC300” on
page 28).
Switch on the SC300.
Perform a teach-in procedure using the key-operated pushbutton for teach-in.
The SC300 locks the internal teach-in key and saves this configuration in the device.
Teach-in can now only be performed using the key-operated pushbutton for teach-in.
Check the effectiveness of the protective device as described in “Test notes” on page 38.
How to unlock the internal teach-in key:
Switch on the SC300.
Press the key-operated pushbutton for teach-in for at least 60 seconds.
The SC300 unlocks the internal teach-in key and saves this configuration in the device.
If you no longer need the key-operated pushbutton for teach-in, remove it from the
electrical installation. Otherwise the SC300 will again lock the internal teach-in key the
next time the key-operated pushbutton for teach-in is actuated.
