Activating/deactivating Know-how protection (KHP) overview

Before the KHP function can be activated for the first time the following steps should be
performed (a simplified flowchart to show the process is given in the figure below).
1. The Inverter must be commissioned for the application before even attempting to activate
the KHP function.
2. The application, for which the Inverter has been commissioned, must be tested to ensure
that all parameter settings functioning correctly.
3. Using parameter p7763, you must set the number of parameters that can be included in
the exception list. The maximum number of parameters that can be included in this list is
500.
4. Using parameter p7764, you must define a list of the parameters you wish to exclude
from the KHP function; this is known as the "exception list". The exception list parameters
will be visible to the end-user and they can be modified.
5. Using parameter p7767, create a new password for the KHP function.
6. Using parameter p7768, confirm the password. Once this step has been completed the
KHP function is activated.
7. The function can now be deactivated or activate by using only p7766 to input the
password that has been created.
A complete example of all these individual steps is given below.
82
Function
KHP new password. Allows a new or an initial password to be created for KHP.
KHP password confirmation.
CAUTION
Important information when implementing KHP
If parameter p7766 is not included or is removed from the exception list, a password can
no longer be entered and KHP cannot be deactivated. If this occurs then the only way to
access the parameters of the Inverter will be to perform a factory reset of all parameters.
