8.1.2 Keyboard Operation
You can use the ENTER key to open and close submenus and to
acknowledge control functions and parameters.
The 4 display keys are assigned to different functions. The key
functions that are currently active are represented as symbols
which can be found in a small framed area on the right-hand side
of the LCD.
In the “Operating display” and “Inverter” menus, you can switch the
inverter on and off using the general keys. The keyboard symbols
in the menu indicate the control function which is currently availa-
ble. If a switch-off procedure has been initiated, you must confirm it
by means of a security prompt in order to avoid inadvertent switch-
ing off. The general control system of the inverter can be blocked
and protected with a password.
If a unit fault occurs, refer to the “Inverter” menu, where the cause
is specified. After eliminating the cause, acknowledge the fault in
the menu. You can then switch the individual converters back on
again.
You can acknowledge the acoustic signal generator using the key-
board. On the LCD operating display you will find a special
acknowledgement key represented by a loudspeaker symbol. In all
other menus, you can press any key (even a key to which no func-
tions have been assigned) to acknowledge the generator. If the
number of messages or faults increases, the acknowledgement is
cancelled. You can impose a general block that inhibits the acous-
tic signal generator in the event of a fault and inhibits the clicking
sound when you press a key.
