SMART WHEEL SENSOR INSTALLATION
The smart wheel sensor should be placed as far away from
the distribution bars as possible using the supplied cable.
1. Dig out the ballast from underneath the rail where the
sensor will be placed.

the sensor must be placed on the gauge side of the
rail, preferably the rail adjacent to the tank. However,
if installing in areas with a conductor rail the smart
wheel sensor should be placed on the opposite rail.
3. Use the shims provided to set the height of the smart
wheel sensor. It should be set so that the top of the sensor is 2” below the top of the rail, any more than this

OPERATION & START UP
General Operation
Once the PROTECTOR IV is installed it is important to understand how it works in order to take full advantage
of all its capabilities. Below is a general theory of operation for the PROTECTOR IV.

the electrical components, such as, the digital control box (DCB), motor, pump, battery and other mechanisms.
Electrical power is used to activate an electric motor that is directly coupled to the pump.
A rail-mounted wheel sensor senses the passage of each wheel on a moving train. As each wheel is detected

from the tank and forces it through the distribution hoses and wiping bars on to the rail. Wheels then pick up
the material and deposit it along the rail in a continuous cycle. A diagram of the cycle can be seen below.
