PROTECTOR® IV Top of Rail Installation, Operation & Maintenance Manual
If the PTO has to cut the power it will need to be reset.
This is performed by holding the toggle switch on the side
of the DCB in prime mode, while simultaneously pressing
the reset button on the PTO device. However, if the PTO
device has been tripped it may mean there is a problem
with either the smart wheel sensor or the DCB which may
need further investigation to prevent the problem from
recurring.
SERVICING & MAINTENANCE
Maintenance Routines
The following sections explain how to perform regular routine maintenance on the PROTECTOR IV unit. These
routines are recommended to ensure the best performance of your unit.
Tank and Pump Unit
Maintain the tank and pump unit on a weekly basis as follows:
1. If the unit is solar powered, check to see which voltage regulator lights are illuminated. This will provide a
quick, initial insight into the condition of the battery. Using a voltmeter, check the voltage at the battery
under load. Voltage below 12v DC under load may cause a problem.
2. Perform the “Control System Integrity Checks” as listed in the Start Up section of the manual. This will

motor will be pumping material for the amount of time on the pump duration setting.
3. Simulate the passing of a train wheel by waving a wrench (or other steel object) over the top of the sensor.
Check to see that the counter has recorded the simulation. If the control system reaches the selected wheel
frequency setting, material will be distributed.
4. Clean away any grease that was distributed during this procedure. Use a rag to wipe this excess material
on the gauge face of the rail in areas adjacent to the bars.
5. Open the material section of the tank and stir the grease. Check for excessive settling of the material and
ensure that there is no blockage at the pump inlet.
Battery Maintenance
he sealed battery and charger provided with the PROTECTOR IV are maintenance free. However, corrosion can
build on the terminals, connectors and/or wires. During regular routine maintenance the battery should be
checked for cracks or leaks. If the battery is cracked or leaking, it should be replaced immediately. If corrosion
is present on the battery, connectors or wires, disconnect the negative and then the positive terminal. Clean
the wires and ends with a wire brush, battery spray cleaner or a solution of baking soda and water. Let it dry
and reconnect the positive then negative terminals. Di-electric grease or battery terminal spray sealer can be
applied to the terminal ends and bolts. If there is severe corrosion it may be necessary to replace the wiring
harness.
