1.3 Safety Concept
1.3.1 Sensors
Analog sensors can be checked for short and open circuit.
1.3.2 System Check
When the trip-reset button is pressed while ignition is being turned on, the system-check function is activated and clears the
contents of the DTC List.
If there are any active service messages, they will be displayed on the Dot-Matrix Display starting with the first active service
message. If the reset button is then pressed and held for 5 seconds or longer, this service message will be reset. The next
active service message is displayed thereafter.
To proceed to the next active service message without resetting the displayed code, the button needs to be pressed shortly
(<5 sec). If all active service codes have been displayed, the system check function is started as described below:
1. All warning lamps and illumination of all gauges are activated for 3 seconds.
2. The Master gauge initializes all configured satellite gauges and waits until they are ready or a Satbus timeout occurs.
3. During time.this, all LCD-Dots are turned on for about 1.5 sec, all pointers are moved to their end value
4. Then all LCD-Dots are turned off and the pointers move back to zero, for about 1.5 sec too, and all warning lamps and
illumination will be turned off
5. Firmware version and Check sum of the EEPROM in hexadecimal format are displayed for about 10 sec.
The display format is as follows:
XX represents a hex-coded value
1.3.3 Satbus
After ignition for synchronisation the Master gets feedback from the satellites.
A timeout function can be programmed too. If more satellites are configured, the Master will not get feedback from all gauges.
After a timeout of about 14 seconds, the Master will act as described before, when the Master gets feedback from all satelli-
tes.
During normal operation there is no feedback from the satellites.
1.3.4 WINgauge
A system diagnosis function for testing all in- and outputs is implemented in the WINgauge Software.

Format Description
2 hXX sXX.XX dd_mm_yyyy hXX specifies the Hardware version relevant to the Firmware
sXX.XX refers to the Firmware version, for example s12.A8 stands for V06
dd_mm-yyyy is the Firmware date in day, month and full-year format.
4 nXXXXwXXyXX cXXXXXX nXXXX is the WINgauge serial number of the device as programmed into the
EEPROM.
wXXyXX displays the production week and year in short format.
cXXXXXX shows the actual 3-byte Checksum of the EEPROM as calculated during
the system check.
