This display units shows a four-digit event message for every

Z

event. Trucks that only use one luminous display (e.g. LED) show the event through a flashing code (see "Display System”). Each event message is also stored in the master logbook. The master logbook describes the event in more detail through the sub index behind the event message (FEXX).

Event numbering display

F E XX S F Function group; E Event group

XX Event number S Sub index

The first two characters “F, E” refer to the category. The middle

Z

two digits “XX” refer to the event. From these two digits the range:

•1 to 50 describes standard events (uniform basic events) which can occur in any function group.

•51 to 99 describes specific events.

The event is described in further detail through the last characters “S” (single digit/multi-digit). This process ensures that a unique number is assigned to each event. Example:

EEPROM data error

The system distinguishes between:

•event messages caused by operator errors.

•event messages caused by truck errors.

For operator errors there are three versions that can be displayed

in the truck depending on the display unit options.

•Event number display (e.g. CANDIS)

•Pictogram display

•Text message display

For truck errors the event number and possibly a fault graphic icon

(e.g. service key) will also be displayed.

Trucks that only use one luminous display (e.g. LED) use the

following flashing code:

•Each character of the four-digit event number is shown with a 2 Hz / 0.5 sec frequency (flashing).

The figure “zero” is displayed by flashing ten times.

Z

•After each character of the four-digit event message there is a pause (LED off) of one second.

•After the complete four-digit event message a 3 second pause (LED off) is set.

Description / cause / action and effects

The following table lists the event message with a description / cause / action and effect.

Z

Each event group (E) with the corresponding event number (XX) can be combined with different function groups (F), hence in the following table the placeholder “F” is used for the first character “F” of the four-digit event number. It also shows the operating status when the event occurred:

Operating status Explanation

Occurs during / directly after truck power up

Bootloader

OperationOccurs during operation

System endOccurs during truck power-down (correct powering down of components, …)

The counts for both incrementers are compared. If the speed of both incrementers > 0.01 km/h and the directions of the speed signals for both incrementers are contradictory, the event is triggered. The activation limit is 100msec.

Both sensor tracks are counted. When the first deviation limit is reached the system waits for a feasible signal from the suspected broken track. When the second limit is reached the event is generated.

The counts for both incrementers are compared. If the lift controller incrementer supplies a speed signal, but the lift height measurement incrementer does not supply a signal after one second, the event is triggered. The activation limit is 20msec.
