override write protection to change zero offset

[Hanemann]

I have the controller 802d sl pro for milling.

I want to undertake a zero offset in order to set the work piece neutral point again.

However I always get the message that there is a write protection in place,when I enter the measured values.

How can I eliminate the write- protection or can I bypass this problem?

I have bought the machine in a used condition, that’s why I have the problem now.

Many thanks for any information.

Hello

Have you got a key switch on your controller?
Maybe this will help you out:
