Change-Enabling Function

Although it is possible to select any data point in the menu tree and read the associated value by pressing the keys, it is not possible to switch directly to the input mode. This safeguard prevents unintended changes in the settings.

There are two ways to enter the input mode.

▪

Global change-enabling function: To activate the global change-enabling function, set the LOC: Param. change enabl. parameter to Yes (menu tree: Oper/CtrlTest/LOC).

The change can only be made after the password has been entered. Thereafter, all further changes – with the exception of specially protected control actions (see Chapter “Password-Protected Control Actions”) – are enabled without entering the password.

▪

Selective change-enabling function: Password input prior to any setting change.

This setup is designed to prevent accidental output and applies even when the global change-enabling function has been activated. The following example is based on the factory-set password. If the password has been changed by the user (see Chapter “Changing the Password”), the following description will apply accordingly.

The same procedure applies to any setting change unless the global change-enabling function has been activated. This method is recommended for a single setting change only. If several settings are to be changed, then the global change-enabling function is preferable. In the following examples, the global change-enabling function has been activated.
