Check for shorts, ground faults or open circuits, e.g., power lines connected to the ground
or a broken cable or connection
→
Check batteries. Batteries should be fully charged and in good conditions
→
Check voltage - minimum 10 volts at motor while activating the UP function with gate in upper position

→
Raise gate up just under pump and motor mounting plate remove hydraulic line at pump and remove
vent cap on reservoir and place line inside hole for vent and press down button on controller (first making
sure all obstacle's are clear and operator is safely clear) If gate lowers with this test then problem is in
pump assembly, remove and replace pump and motor assembly.( for this test see illustration on page 13 )

If not, check power supply to up/down switch and signal line to Lift/Lower valve while activating
lowering function (check for voltage while activating function)
→
Valve is energized
– check grounding of valve and make sure, ( see pictures on page 14 ) valve is
shifted over (hear click)
