MoTeC Operation 21
General Purpose Calculations:
The ACL also provides a number of general purpose calculations including:
• 2D and 3D Lookup Tables
• User Defined Conditions
• General Purpose Timers
• Mathematics
• Bit
Combine
• PID
Control
The user defined conditions or tables can be used to activate items such as a
Thermatic Fan or Gearbox Oil Pump.
For details on all calculations refer to the help in ACL Manager.
Measurement Inputs
The ACL’s external measurement devices have inputs that can be connected
to a wide variety of sensors.
Sensors
Different types of sensors are available to suit different types of
measurements, for example: temperature, pressure, movement etc.
Sensors convert a physical measurement (e.g. pressure) into an electrical
signal (e.g. volts).
Different types of sensors generate different types of electrical signals. For
example most temperature sensors convert the temperature into a variable
resistance which may be measured by an Analogue Temperature input,
however most wheel speed sensors generate a variable frequency signal
which must be connected to either a Digital input or a Speed input.
Sensor Amplifiers
Some sensors may require an amplifier to be connected between their
output and the measurement device input. This will depend on whether
the measurement device supports direct measurement of the particular
type of sensor. For example an ADL2 does not allow direct
measurement of thermocouples whereas both the E888 and VIM do.
