5. Scroll to the next menu point or to the end of the menu, which returns the display to the set point value,

7.2.2 Reset set-point to zero
for units that do not have I/O keys on the front panel
When a setting has been left in an undesirable state, e.g. hammering of the coil could occur or too high a
current inrush, causing nuisance tripping, the set-point can be instantly reset to zero in the following manner:
Press the down cursor key whilst
switching on the supply using the mains switch.
Using this procedure, after resetting to zero, the set-point can be increased again gradually or the frequency
setting can be changed, for instance.
7.2.3 Six key control panel
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,
these do not pro-
vide mains isolation,
they simply inhibit the
power semiconductors
The “P“, “F“ and “Cursor Buttons“ are used for
parameter adjustment. Parameters are set by
using menu controls which are called up by en-
tering operator codes. These are explained in
more detail in the section “setting up instructions“.
The display value can be increased or decreased
by units, or tenths of units, by a short press of the
cursor buttons. Holding the buttons down will
cause the display to change in units often.
To prevent accidental or unauthorized adjustment the parameter settings are stored under user menus. A
pass code must be entered to open the menus. Different menu codes are provided for the various function
groups (refer to controller operating instructions).
Changed values are saved upon leaving the programming mode or if no keys are pressed for a pe-
riod of 100 seconds.
