2. Press the wheels button.
3. Use the up and down arrow buttons to set the desired wheel count between pump activations.
4. Press the pump button.

7. Watch the LCD screen until it shows the number of wheels between activation and the duration of pump
activation to verify that the desired settings have been stored to memory.

can produce puddles that tend to be splashed in various directions by the train wheels.
For normal operating conditions the pump duration should not exceed 0.5 seconds. The control settings may
need to be adjusted periodically to suit changes in material and temperature.

Pump Time Out (PTO) Device Operation
The PTO device has been incorporated into the PROTECTOR IV unit as a fail safe. In the event of a DCB

will never fully re-charge. The pump time out device prevents this from occurring by automatically cutting the
power to the motor if it operates continuously for 30 seconds.
