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 messagesand analogue sensor values. Input values are then monitored and if the configured thresholds are exceeded, then an Alarmor Warning action is triggered, resulting in switch outputs being activated.2.5.4.1Description of the OutputsDefinitions: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 ismore 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 2These are two outputs, which act like two switches to ground. The switch output can control i.e. a warning lamp, a buzzer ora relay. It turns off, when the Alarm condition is not existing anymore, or if the Alarm has been acknowledged and it was con-figured. It stays on, if another Alarm condition also configured to turn on this output is still active.b. DisplayEvery Alarm or Warning activates a display on the dot matrix. When the Alarm is triggered, then the associated display appe-ars on the dot matrix, overwriting the previous display. The display combines a graphic symbol with a physical value (numeri-cal value plus physical unit), describing the input value, which has caused the Alarm or Warning.c. Warning Lamps in the Satellite GaugesThe Satellite Gauges include a warning lamp. This warning lamp can be turned on and off via the Sat-Bus. An Alarm orWarning could be configured to activate a warning lamp in each of the Satellite Gauges. The selected warning lamp in theSatellite Gauge remains on as long as the trigger condition remains, and turns off as soon as the trigger condition is not exi-sting anymore. Flashing of the warning lamp can be configurated.2.5.4.2Switch Output Acknowledgement FunctionThe Acknowledgement Function provides a means to turn off some of the switch output action. This may be desired, if theAlarm 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 acti-ve.When a Warning or Alarm has been acknowledged, then the Switch Outputs (1, 2) will be deactivated, if they have been con-figured to turn off these outputs.2.
