Configuration of the Function Keys F1 to Fx

Function keys [F1] to [Fx] can be assigned a password (see Chapter “Changing the Password”). In such a case they are effective only after that password has been entered. By default, no password is required to use the function key.

It is assumed for the following operating example that function key [F1] is enabled only after the password (as assigned at F_KEY: Password funct.key 1) has been entered. After the password has been entered the function key will remain active for the duration set at F_KEY: Return time fct.keys. Thereafter, the function key is disabled until the password is entered again.

Step 1

Press function key [F1].

Eight asterisks (*) appear in the fourth line as a prompt to enter the password if it is required.

(By default, i.e. no password required, this step and the next do not exist and the function key is effective immediately as described in Step 3.)

Step 2a

If a password is set, press the keys corresponding to the set password, for example:

“Left”

“Down”

“Right”

“Up”

The display will change as shown in the right hand side column.

Now press the ENTER key. If the correct password has been entered, the active display will re-appear. Function key [F1] is now effective for the set return time.

By default, no password is required and therefore function key [F1] is always effective.

Each function key can be assigned its own password, and the return time is running after correct password entry for each individual function key!)

If an invalid password has been entered, the display shown above in Step 1 will appear.

Voltage A-B prim.
     20.7 kV
Voltage B-C prim.
     20.6 kV

Step 2b

This control step can be canceled at any time by pressing the CLEAR key before the ENTER key is pressed.

Voltage A-B prim.
     20.7 kV
Voltage B-C prim.
     20.6 kV

Step 3

Press [F1] again. The function configured to this function key is carried out.

Voltage A-B prim.
     20.7 kV
Voltage B-C prim.
     20.6 kV

Step 4

When function keys are pressed during their associated return time, then the set function is carried out directly, i.e. without checking for the password again.

(By default, i.e. no password required, this step does not exist and the function key is permanently effective.)
