5.5. Code Protection against Unauthorized Keypad Access
Parameter group F05 allows to define an own locking code for each of the parameter menus.
This permits to limit access to certain parameter groups to specific persons only.
When accessing a protected parameter group, the display will first show “CODE” and wait for
your entry. To continue keypad operations you must now enter the code which you have stored
before, otherwise the unit will return to normal operation again.
After entering your code, press the ENTER key and keep it down until the unit responds.
When your code was correct, the response will be “YES” and the menu will work normally.
With incorrect code the response will be “NO” and the menu remains locked.
5.6. Return from the Programming Levels and Time-Out Function
At any time the PROG key sets the menu one level up and finally returns to normal operation.
The same step occurs automatically via the time-out function, when during a period of 10
seconds no key has been touched.
Termination of the menu by automatic time-out will not store new settings, unless they have
already been stored by the PROG key after editing.
5.7. Reset all Parameters to Factory Default Values
Upon special need it may be desirable to set all parameters back to their original factory
settings (e.g. because you have forgotten your access code, or by too many change of settings
you have achieved a complex parameter state). Default values are indicated in the parameter
tables shown later.
To reset the unit to default, please take the following steps:
•
Switch power off
•
Press
and
simultaneously
•
Switch power on while you keep down both keys
Where you decide to take this action, please note that all parameters and
settings will be lost, and that you will need to run a new setup procedure
again.
