5100ex Calibration Manual
Description of Calibration Values
5
Speed
The Speed menu allows you to configure settings for the vehicle's speedometer input.
Type
The Type menu item selects the type of speedometer the 5100ex is connected to, either
Electronic or Mechanical. Electronic is a high-impedance setting suitable for most modern
vehicles. Mechanical enables a pull-up on the speedometer signal for compatibility with
legacy speedometer sensors. The default value is Electronic.
Low Trip
The Low Trip Point sets the voltage that the speedometer signal must drop below in order
to cause a pulse. The default value is 0.5 V which should work with most vehicle
speedometer signals. The low trip point is used to read Axle Pulses; if it is not set
correctly, the 5100ex will never register a valid vehicle speed.
The Low Trip Point should be set when the vehicle is moving. Have a passenger slowly
increase the low trip point until the menu item shows a mph/kph value greater than 0. In
some cases, it may be necessary to adjust the High Trip point in conjunction with the Low
Trip point to read a vehicle speed.
High Trip
The High Trip Point sets the voltage that the speedometer signal must climb above in
order to cause a pulse. The default value is 2.0 V which should work with most vehicle
speedometer signals. The high trip point is used to calculate Axle Pulses; if it is not set
correctly, the 5100ex will never register a valid vehicle speed.
The High Trip Point should be set when the vehicle is moving. Have a passenger slowly
decrease the high trip point until the menu item shows a mph/kph value greater than 0. In
some cases, it may be necessary to adjust the High Trip point in conjunction with the Low
Trip point to read a vehicle speed.
Axle Pulses
The Axle Pulses menu item allows you to manually set how many pulses from the
speedometer input are expected in 1 mile or kilometer. The current vehicle speed will
update as you adjust the value. The default value is 40000 pulses per mile or 24855
pulses per kilometer.
Axle Pulses are used in all closed and open loop operating modes, and should be
configured as accurately as possible. If you already know your vehicle’s axle pulses per
mile or kilometer you can enter the value directly using this menu. If you aren’t sure of the
Axle Pulses per mile or kilometer, they can also be set automatically using the Cal By
Distance menu item.
Cal By Distance
The Cal By Distance menu item will calibrate your axle pulses by counting pulses while
you drive exactly 1 mile or kilometer. For more information on how to use Cal By
Distance, please see Calibrating Axle Pulses By Distance on page 29.
Using the Cal By Distance menu item will change the value of the Axle Pulses menu
item. Further refinement can be done by manually changing the Axle Pulses menu item.
Jump Start
The Jump Start Speed menu item sets a speed in miles per hour or kilometers per hour.
If the actual vehicle speed is below the Jump Start Speed, the spreader will operate using
the Jump Start Speed. The default value is 15 mph or 24 kph.
