General Information
Depending on their design, controller boards of Generation 4
have a keypad with 6 keys and an LCD for status and diag-
nostics displays. The display is carried out via LEDs or sys-
tem messages (by means of driver blocks).
This guide describes the operation of the diagnostic display,
the signal representation of LEDs, and system messages in-
dicated via driver blocks.
The descriptions refer to the firmware version 4.x. Information
on the firmware version is indicated in the text by the short-
form "FW4.0".
When using this guide, please observe the following notes:
The front cover page shows an overview of the menu
structure of the controller board.
The
attention
symbol refers to erroneous handling,
which could lead to damage to the hardware or soft-
ware or to personal injury. This symbol is always loca-
ted to the left of the tagged text.
The
hand
symbol gives you tips and advice on the ef-
ficient use of hardware and on software optimization.
In addition, text marked in this way informs you of sy-
stem-related conditions that must absolutely be ob-
served to achieve error-free operation. The hand is
also found in front of clarifications of terms.
The
text
symbol refers to detailed sources on informa-
tion (manuals, data sheets, literature, etc.) on the sub-
ject matter, product, etc. This text also provides helpful
information for the orientation, reading order etc. in the
manual.
