8. Operation
8.1 Control elements
The converter operates using the following con-
trol elements:
The encoder
Setting with encoder
• The selection of a new parameter is done only
with a simple rotation, « + » on right and « - »
on left.
• A short impulse on the encoder validates this
new setting.
Switches
• This converter has got a block with
two switches with two positions each
(Fig.4, item 18):
• Switch 1 allows to change the « OPERATION »
mode [switch 1->OFF] to « SERVICE » mode
[switch 1->ON] and conversely. The « OPERA-
TION » position allows the selected mode to run
and hinders the access to parameters input (nor-
mal operating). The « SERVICE » position is used
to enter the parameters of the different opera-
tions.
• Switch 2 is for activating or deactivating the
« Access lock », see <chapter 8.5.3>.

8.4.1 Display status page
• The status page is shown as the standard view on
the display.

Example of display status page
NOTE: If the encoder is not activated within 30
seconds in all menus, the display returns to the
status page and the change is not registered.
8.4.2 Navigation element
• The arborescence of the menu allows to call the
functions of the converter. A number is attrib-
uted to every menu and submenu.
• The rotation of the encoder allows the scrolling
of a same menu level (example 4000->5000).
• Any blinking elements (value, menu number,
symbol or icon) allow the choice of a new value,
a new menu number or a new function.
