4.3.11- Description of the configuration menu

4.3.11.1- General

This menu can be used to display and modify all configura- tions: Factory, Service and User. Only the User Configuration can be modified by the end-user. The Factory, Service and master/ slave configurations are not described in this document. A configuration can only be modified if the unit is fully stopped (LOFF).

The menus User 1 [USEr 1] and User 2 [USEr 2] are pass- word-protected. The other menus are directly accessible, except if item 11 of the User 2 menu (password for all con- figurations) has been validated.

4.3.11.2 - Password

A password must be entered in order to access the test function or to modify a configuration. It is automatically requested, if necessary: 'EntEr PASS' is displayed on the 4-digit display and the configuration menu LED flashes, indicating that the modification mode is active. Press the arrow keys until the value '11' is displayed on the 4-digit display. Press Enter to validate this. The configuration menu LED stops flashing. If the password is correct, 'Good' is displayed. If the password is incorrect, 'PASS incorrEct' is displayed. The User password has a default value of 11.

This value can be modified through the Service configuration. The password can be entered if the unit is fully stopped, otherwise 'ACCES dEniEd' (access denied) will be displayed on the 4-digit display. The controller automatically deactivates the password after 5 minutes without activity (i.e. no buttons pressed) or after powering up.
