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 current
key functions 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 in the “system”, you can switch the
converters on and off using the general keys. The key symbols in
the menu indicate the control functions which are currently available.
You can only switch off the rectifier in the “operating display” when
the inverter is switched off and while a general control is enabled in
the “system”. If a switch-off procedure has been initiated, you must
confirm it in the safety routine, so that the unit cannot be inadvertently
switched off. The general control of the power converters can be
blocked and protected with a password.
If a unit fault occurs, you must refer to the “system” where the
cause is specified. After eliminating the cause, you must
acknowledge the fault in the menu. You can then switch the
individual power converters back on.
You can acknowledge the acoustic signal generator using the
keyboard. On the LCD operating display you will find a special
acknowledgement key represented by the symbol of a loudspeaker.
In all other menus, press any key (even a key without function) to
acknowledge. If the number of messages or faults increases, the
acknowledgement is cancelled. You can generally block both the
acoustic signal generator from notifying you of faults and the clicking
sound when you press a key.
