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 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 (see section 5.3 on page 33).
⋅
Switch on the V200/V300.
⋅
Perform a teach-in procedure
using the key-operated pushbutton for teach-in
.
The V200/V300 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.
