4.1 Controls
The six buttons and a LED display found in the front-
panel are used for operating and setting up the unit.
All operating methods and adjustable parameters can
be set up through this panel.
The “I” and “O” buttons are used for switching the unit
ON and OFF, however,
this does not provide
mains isolation, it simply inhibits the power semi-
conductors.
The “P”, “F” and “Cursor Buttons” are used for pa-
rameter adjustment. Parameters are set by using
menu controls which are called up by entering opera-
tor codes. A capital letter is used to indicate the se-
lected function.
4.2 Adjustment:
The display value can be increased or decreased by units, or tenths of units, by a short press of either
cursor button. Holding a button down will cause the display to change in units of ten.
To prevent accidental or unauthorized adjustment the adjustment parameters, in the user menus, are
protected. A code must be entered to open the user menus. There are different pass codes for each func-
tion group.
Setting adjustments are automatically saved upon leaving the programming mode or if no button
is pressed for a period of 100 seconds.
