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

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

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:

Sub-division of function group "F"

System: Overlapping functions that cannot be assigned to any other

function group) Example: seat switch / deadman switch or master controller

7 Additional modules

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.

• 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.

8 CAN monitoring

Description / cause / action and effects

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

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

(basic initialisation of components, possible change to flash mode). Example: Checking the RAM / ROM (memory check)

System start

Self test

Operation Occurs during operation

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

Undefined Can occur at any time

Occurs during installation of operating software of individual components. Example: correct hardware installed, ...

Occurs during the self-test of each component, as coordinated by the master

→ The main contactor is then closed
