General display functions and operation

Apart from its normal display function the LC display is also able to show error codes, which had
previously been visualized by means of the 3-digit error code display.
Currently existing faults and warnings are displayed by flashing. If several faults are detected, the
displayed fault codes will change in a 3 second cycle.
Display values are permanently displayed, whereby values from 0 0 0 0 ...9 9 9 9 are possible.
Negative values are identified by a "Minus sign".
The following chapter describes the operation of the LC display via travel lever buttons.

7.1.1 Calling up service mode

For this purpose the display must be switched via input mode to service mode. This is accomplished
via the two yellow Info-buttons "INFO 1" and "INFO 2" on the back of the travel lever. Navigation in
input and service mode takes place via the green buttons on the front and the blue buttons on the
back of the travel lever.
The travel lever must be in locked braking position in order to activate input mode! Input mode
is switched on by simultaneously pressing both INFO – buttons over a period of approx. 3
seconds.

7.1.2 Entering input codes

Input mode starts with flashing of the left hand digit. Here service code9 9 9 9 provides the possibility
to change to the service mode. The green buttons can be used to increase or reduce the values of the
corresponding digit. By operating one of the blue buttons one can jump to the next (left or right) digit.
Once the last right hand digit has been entered the code will be transferred to the control by pressing
the right hand blue button once again.
If the access code has been entered correctly, the "Spanner" symbol is displayed and the first input
digit flashes again. Individual operating states of the machine can now be interrogated by transferring
the input code to the control (as described above).
When operating both INFO buttons again for approx. 3 seconds, another input code can be entered.
The input of code "0 0 0 0 " or switching of the ignition quits the service mode.
If the travel lever is shifted out of the brake lock while in service mode, all machine functions will
become active, with the exception of the LC-display, which remains in service mode and continues to
display the operating values requested last.
