4.3.10.3 - Manual tests
This function allows the user to test the outputs individually,
if the machine is completely shut down (LOFF). To carry
out a manual test use the arrow keys to access the output to
be tested and press the Enter key (longer than 2 seconds)
to activate the modification mode. The password is auto-
matically requested, if it has not previously been verified.
The Outputs/Test LED on the user interface begins to flash.
Enter the desired test value and again press Enter to start
the test. 'TESt' is displayed on the 4-digit display alternately
with the value tested. The Outputs/Test LED stops flashing.
Press the Enter key or an arrow key to stop the test.

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

is fully stopped (LOFF).
The menus User 1 [USEr 1] and User 2 [USEr 2] are
password-protected. The other menus are directly accessible,
except if item 11 of the User 2 menu (password for all

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

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 deacti-
vates the password after 5 minutes without activity (i.e. no
buttons pressed) or after powering up.
