6.5 Locking/unlocking operation
Once you have entered all the parameters, you can lock your entries against unauthorised and
undesired access.
You have the following possibilities for locking/unlocking the operation:
• Via a DIP-switch on the electronic insert (see Page 20, Fig. 7).
• Via the on-site display (optional)
• Via digital communication.
The -symbol on the on-site display indicates that operation is locked. Parameters which refer
to how the display appears, e.g. LANGUAGE and DISPLAY CONTRAST can still be altered.
• If operation is locked by means of the DIP-switch, you can only unlock operation again by
means of the DIP-switch. If operation is locked by means of remote operation e.g. FieldCare,
you can only unlock operation again by means of remote operation.
