Description….
An effective driver assistance system
to prevent engine damage before it
occurs

    Engine block
     temperature
    Oil pressure
    Coolant level




                                        2
Main features….

   Display panel on dash board.
   Audio and visual warnings.
   Two-stage temperature response.
   Warnings are followed by engine shut down before
    damage occurs.
   Engine shut down events are stored in memory, to
    be recalled afterwards.
   Digital outputs to external devices, such as fleet
    management systems.
   Suitable for high temperature engines.
   Suitable for high operating temperatures.

                                                         3
Benefits….
   Engine damaged is effectively prevented.
   Drivers are assisted to take preventative
    action.
   Large repair costs are prevented.
   Loss of production due to down time is
    prevented.
   Vehicle productivity and customer service is
    improved.
   Reduced expenses result in increased profit.
   Low cost installation.
                                                   4
Operation….
Temperature:
    Engine METAL temperature is monitored,
     independent of the vehicle’s temperature
     sensor.
    Two stage response:
  1.    Audio and visual warning when engine
        starts to rise above normal.
  2.    Engine is shut down when temperature
        rises further to near dangerous levels.
    Engine temperature has to return to normal
     before the system resets.
    Temperature response levels are according
     to manufacturer specifications.
    Covers all sources of overheating.

                                                  5
Operation….(continued)
Oil pressure:
 Oil pressure is monitored from the vehicle’s oil pressure switch.

 After starting the engine a time of 10 seconds is allowed for the
   pressure to stabilise.
 If the oil pressure fails at any time, the engine is shut down
   immediately, before damage can occur.
   This display indicates the status and the event is stored in
   memory.

Water level:
 An independent float switch is installed in the expansion tank.

 When the coolant drops below the allowed minimum, a warning
  will alert the driver.
 If the warning is ignored, the engine will be shut down.


                                                                      6
Competitive advantages….
   Engine metal temperature is monitored, as opposed to water temperature.
    This advanced approach renders much faster response time, and covers all
    causes of over heating.
   Rising engine temperature is detected long before water temperature rises,
    improving engine protection.
   Maximum temperature parameters are programmed according to engine
    specifications of the specific vehicle.
   Two temperature parameters are used, the first as a warning of rising
    temperature, and the second to shut the engine down when a dangerous level is
    approached.
   Digital outputs can be connected to any fleet management system.
   Suitable for all engines, 12 and 24 Volt DC.
   Suitable for plant and machinery.
   The system features an advanced micro processor, incorporating the latest
    technology, rendering extreme accuracy and split second response time.
   Audible warnings alert the driver while his concentration is on the road.
   Visual display indicates status of engine temperature, water level and oil pressure
    continuously.
   Onboard memory gives evidence of the most recent occurrences of violations.
   The system is non volatile and stable under all operating conditions.
