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:

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

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

G

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

When the truck begins to brake, the maximum brake time is calculated based on the current travel speed. As soon as this time is exceeded, the event message is triggered.

When the truck begins to brake, the minimum permissible brake time is calculated based on the current travel speed. If this time is not attained, the event message is triggered.

Specifically for system trucks: internal power supply interrupted The AC-3 Power Control (U8) monitors the internal supply voltages for deviations. In the event of an error the AC-3 Power Control component (current transformer) is damaged.

A digital signal generated outside the processor shows the status "key switch low voltage" and automatically disables the power stages. Activation limit, timing and truck response therefore depend on the switch and must not be changed through the software.

“Battery semi-voltage” signal implausible

Battery full discharge voltage limit exceeded

Description Cause / Triggering Event Action

Battery controller: “Battery semi-voltage” signal implausible. The prompt is issued after T = 250 msec: This event message is triggered if the following applies for T = 2 sec: Voltage over half the cells should be half the battery voltage. If there is a deviation of more than ± 1.5 V between the two halves, the event message is triggered.

Battery controller: Battery full discharge voltage limit exceeded. The event message is triggered if the discharge voltage is too low before the battery capacity is zero.

Mains voltage <= 0.9*rated voltage for longer than 60 sec

- Check the measuring lead of the battery controller is connected to the right cell (GND, V

- Measure the cell voltage of each battery cell;

- Check battery controller cable connection;

- Check charge characteristic against battery data plate and adjust as required;

- Charge the battery;

- Measure the cell voltage of each battery cell;

- Measure the voltage on the connector cables of the battery controller; compare the reading with that measured by the battery controller and if necessary replace the battery controller;

- The charger may continue charging with a low current. The charge time may be extended. This event message is designed for information purposes in case the charge times are not maintained.
