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 satellites.

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.

2.2 Mechanical Concept

As the same LCD is used for different Master gauge diameters the pointer position has different eccentricities and indication angles.

The connectors are 26-Pin MODU II-Connector and 4-Pin MATE-N-LOK from AMP.

2.2.1 Master dia. 80 mm

Two PCB's are necessary for this diameter. They are connected with a standard pin connector and two distance towers.

2.2.2 Master dia. 85 mm

The PCB assemblies and their corresponding parts of the Ø 80 mm and Ø 85 mm gauges are identical. The difference between the two gauges is the position of the stepper motor on the PCB so that the eccentricity of 7 mm in the Ø 80 mm gauge can be reduced to 4.5 mm in the Ø 85 mm gauge.

2.2.3 Master dia. 100 mm

For this size, only one PCB assembly is necessary. Input Signal Processing.

2.3 Input Signal Processing

2.3.1 Analog Inputs

All sensor characteristics can be defined with the WINgauge Software.

2.3.1.1 Grounding Concept

The Master gauge has two main ground lines. Ground term.31 is connected to the vehicle's body (negative battery terminal) and Sensor Ground is supplied from the instrument; insulated return sender are necessary. The Sensor Ground should not be connected to vehicle ground, which would result in a higher current flowing through this line and thus produce a signal noise and measurement error. Sensor Ground and Ground term.31 are joined together inside the Master Gauge. This grounding principle is necessary to accurately measure analog values. Ground shift on Sensor Ground is minimized by this concept.

2.3.1.2Sensors

The static and dynamic voltage drop of the sensors should not exceed 0.5 V.

Pressure: 10 - 184 Ohms Temperature: 10 - 700 Ohms Fuel lever type: 3 - 180 Ohms Fuel dip-pipe: 0.5 - 90 Ohms Other sensors: 4 - 20 mA Other sensors: 0 - 5 V

2.3.2 Input Signal Processing applied to the two frequency inputs

Frequency 1:

The standard modules can be changed to 500 < k < 400 000 pulses/km or miles for the Speedometer and 0.5 - 400 pulses/rev for the Tachometer.

Maximum frequency is 40 kHz (2 kHz via internal divider).

Frequency 2 as Hall Sensor / Terminal W:

500 < k < 65000 pulses/km or miles for Speedometer and 0.5 - 65 pulses/rev for Tachometer.

Maximum frequency is 2 kHz.

2.3.3 Input Signal Processing for CANbus messages

Example of SAE J1939 Messages received on one of the two CANbus Interfaces.

The Master Gauge CANbus interface conforms to CAN 2.0B specification and supports extended (29Bit) identifiers. The Gauge acts as a "Standard ECU, which is non-configurable as defined in SAE J1939. The application layer is based on SAE J1939/71 Rev 2008-01.

Additional communication protocol is CAN Open For this the different CANbus data bases will be provided by the WINgauge configuration.

2.5 Display Functions

Five main display functions have been specified for the Master gauge. (s. picture below) As the number of displays in each main function is configurable (except for odometer and hourmeter), the actual number of displays can be up to a maximum of

146.

A maximum of 30 Warnings and 30 Alarms can be set. The Physical Values of the defined Satellite gauges can be shown on the display (if configured). Atotal of 25 physical value Displays (PVD) are possible, including the physical values inidcated by the Satellite gauges. Thus with increasing numbers of Slaves defined by WINgauge, the number of freely selectable physical values to be displayed on the dot-matrix decreases.

2.5.1 Navigation through Display

The order of the display groups is: Odometer / Hourmeter, Alarms, CAN DTCs, Service Messages, Physical Values, Warnings and then back to Odometer / Hourmeter. The Alarms, CAN-DTCs, Service Messages and Warnings are being monitored and appear only if they are activated. If the button is pressed more than 2 sec., the LCD shows the main display which is Odometer / Hourmeter.

2.5.2 Display Layout

The Dot-matrix Display has 132 x 33 dots. The following picture shows the proposed display layout. The outer line represents the LCD glass and the inside marks the active display area. The structure inside has only been drawn for illustration; it is not visible on the display itself

The display is structured into three main areas:

1. Symbol Area

This 30 x 32 pixel area is reserved for graphic symbols. The symbols are left aligned to optically enlarge the appearance of the symbol.

2. Central Area

The centre of the display is organised as one or two lines with 6 digits each. Here it is possible to show alphanumeric ASCII characters using the large font (12 x 16 pixel). If only one line is displayed, then this line will be centred in vertical direction. Short text (up to 6 letters) can be used to provide identification for the value displayed. This area is best suited to communicate important numeric values to the user. Values will be shown in the second line on the right, where units appear on the left. One or two centre lines are configured via WINgauge as well as the description of the short text.

3. Physical Unit Area

The physical unit area is located right of the alphanumeric Centre Lines. In general the unit belonging to the value displayed on the centre lines is shown here as text. This area is organised as four lines of 5 characters of the small font. If the Unit can be displayed with less than three ASCII characters, then the large font is applied, else the small font is used. Units will not be wrapped into the next line.

If there are two Centre Lines, then there will also be two-unit Lines (small Line 2 and Line 4). In case only one Centre Line is displayed, then only one corresponding Unit Line will be visible (small Line 3).

It is therefore possible to show the following parameters and units to give a clear indication of the valid physical unit which can be chosen via WINgauge:

2.5.3 Display Functions

2.5.3.1 Main Display (Odometer, Hourmeter)

The display shows total and trip in two lines. Total has 6 digits and trip has 4 plus 1 digit. The figures roll over to 0.0 after a distance of 999.999 /

9.999 or 100.000 / 1.000 hours. Pressing the button longer than 2 seconds will reset trip odometer or hourmeter. A part of the Display can be used to show the company logo as a start-up display configured by WINgauge

The centre of the display shows the value of the odometer in the first line and the tripmeter underneath. The physical unit is displayed right to it and can be either miles or km.

The main display of the tachometer is similar to the speedometer, except that it shows operating hours instead of odometer and trip meter. The physical unit is "h" for hours. The digit after the decimal point of the trip hourmeter shows 1/10h.

if no CAN signal is received, only dashes will be indicated.

2.5.3.2 Alarm Display

If an alarm is triggered the Alarm Display is shown. To alert the user, the General- Alarm-Symbol is flashing, alternating with the symbol that indicates the type of alarm. The Central area of the display shows the actual physical value (6digits). The physical unit appears to the right.

When the customer quits the alarm longer two seconds the Display will change to the last displayed value (if no other Alarm and Warning is existing which weren't quitted). The General Alarm Symbol will remain in the graphic Symbol Area with a vertical line on the right side of the symbol to indicate that the Alarm doesn't correspond to the main display but to another Physical Value.

When different Alarms are present the highest priority will be shown. The priority of the alarms is defined with the WINgauge Software. If the Alarm is confirmed and the Alarm condition does not exist anymore then the Alarm is cleared in the list of active Alarms. If the Alarm is not confirmed but the Alarm conditon does not exist anymore then the Alarm is still in the list of active Alarms.

o see the different Alarms in the Alarm display group the button has to be

pressed shortly (>50 msec).

2.5.3.3 CAN DTC Display

1 to 5 independent DTC channels can be configured. Every channel is able to receive the DTCs from one CAN device (Source Address). If DTCs are received from any of the configured CAN devices, they will be stored into a DTC receive buffer. The buffer will be able to hold a total of 40 DTCs and will be implemented as a ring buffer, so that old DTCs can be overwritten by newly received DTCs

2.5.3.4 Warning Display

In the Warning display the Specific Graphic Symbol (ISO) is flashing at 1 Hz. There is no alternating.

The operator can acknowledge the Warning by pressing the button longer than two seconds. The Display will change to the Display, which was active before, if no other Alarms and Warnings are existing, which have not been acknowledged yet.

When different Warnings are present the highest priority will be shown. The priority of the Warnings is defined with the WINgauge Software. Alarms have higher priorities than the Warnings. If the Warning condition vanishes also the Warning will vanish, if it has been acknowledged. To see the different Warnings in the Warning display group the button has to be pressed longer than 50 msec.

2.5.3.5 Service Message

The Service Message indication is based on operating hours and odometer.

The Graphic Symbol Area displays the "Service Symbol" in case a Service Message becomes due.

The corresponding service code is shown on the centre line of the display centre. As a "unit" the word "CODE" appears to indicate, that the value is a code number.

To see the different active Service Messages in the Service Message display group the button has to be pressed longer than 50 msec.

2.5.3.6 Physical Value Display

The graphic display area shows a symbol relating to the physical value displayed. The symbol can be selected via configuration from the defined symbols in ROM or EEPROM. In the standard form the physical value is shown on a single Centre-Line, followed by the physical unit. This unit text can be selected from ROM during configuration.

If the value is outside of the configurated range, then "------" is shown.

To see the different Physical Values in the Physical Value display group the button has to be pressed longer than 50 msec

2.5.4 Alarm- and Warning Functions

The Alarms and Warnings are triggered by the input values. Configuration parameters in EEPROM select the input values. These variables can have a size of 1, 8 and 16 bit. Possible inputs are engine speed, road speed, data in CAN messages and analogue sensor values. Input values are then monitored and if the configured thresholds are exceeded, then an Alarm or Warning action is triggered, resulting in switch outputs being activated.

2.5.4.1 Description of the Outputs

Definitions: Warning: Is a message to make the operator aware of a condition, which requires his attention. Alarm: Is a message to alert the operator about a condition, which requires his attention and immediate action. The Alarm is

more severe than a Warning.

The switch outputs are only controlled by the Alarm- and Warning Functions.

The following switch outputs are provided: a. Output 1 and Output 2

These are two outputs, which act like two switches to ground. The switch output can control i.e. a warning lamp, a buzzer or a relay. It turns off, when the Alarm condition is not existing anymore, or if the Alarm has been acknowledged and it was configured. It stays on, if another Alarm condition also configured to turn on this output is still active.

b. Display

Every Alarm or Warning activates a display on the dot matrix. When the Alarm is triggered, then the associated display appears on the dot matrix, overwriting the previous display. The display combines a graphic symbol with a physical value (numerical value plus physical unit), describing the input value, which has caused the Alarm or Warning.

c. Warning Lamps in the Satellite Gauges

The Satellite Gauges include a warning lamp. This warning lamp can be turned on and off via the Sat-Bus. An Alarm or Warning could be configured to activate a warning lamp in each of the Satellite Gauges. The selected warning lamp in the Satellite Gauge remains on as long as the trigger condition remains, and turns off as soon as the trigger condition is not existing anymore. Flashing of the warning lamp can be configurated.

2.5.4.2 Switch Output Acknowledgement Function

The Acknowledgement Function provides a means to turn off some of the switch output action. This may be desired, if the Alarm activates a buzzer and the operator wants to turn the buzzer off.

To acknowledge a switch output, the operator must press the button for more than 2 sec, while the Alarm or Warning is active.

When a Warning or Alarm has been acknowledged, then the Switch Outputs (1, 2) will be deactivated, if they have been configured to turn off these outputs.

2.5.4.3 Alarm and Warning Trigger Conditions

The diagram above illustrates the Alarm and Warning trigger conditions for the engine coolant temperature as an example. The Warning threshold is set at 105° C, where the Alarm threshold is reached at 110° C. To prevent repeated on/off cycles of the Warning or the Alarm an activation hysteresis is applied. Therefore in above example an Alarm is turned off, if the temperature falls below 108° C and the warning is cancelled at 103° C. The hysteresis is 2° C in this case and is the same for both Alarm- and Warning condition. In addition a turn-on delay from 1 sec to 4 minutes can be configured. The delay time starts, when the threshold is reached. If the input value falls below the threshold value, then the delay time restarts from this point in time.

It can be configured, that the Warning is triggered, if a value rises above a threshold (as in the case of the engine coolant temp.), or if the input value falls below a threshold (e.g. fuel level).

2.5.4.4 Alarm and Warning Trigger enabling with Engine running

Triggering of some Alarms and Warnings only makes sense, when the engine is actually running. Examples are engine oil pressure or hydraulic pressure. For these situations triggering an Alarm and Warning can be disabled until the engine is running. This conditional trigger enable is selectable for every Alarm and Warning (together) during configuration.

Engine running is detected, by exceeding a separately configurable threshold value: the Alarm and Warning enable engine speed threshold. The minimum threshold is 0 rpm and the maximum is 32.000 rpm.

An additional trigger-enable time delay starting from engine running condition can be configured. This is helpfull in cases, where it takes a while until a pressure is built up. This delay time is settable from 0 to 250 sec with a resolution of 1sec.
