4E.
The R.P.M. Sensor is counting the r.p.m ‘s of the wheel that is attached to the shaft. There are no
repairable parts for the sensor of wheel. The only thing that should be checked is the wire
harness. Make sure that the wires are crimpled and fully seated into the housing. Also make sure
that the housing is fully seated into the circuit board.
4F.
The circuit board is the “brains” of the entire system. It is a non-repairable item. In many cases,
un-awareness of the different programs and their functions can make it look like there is a
problem when in actuality it is just a missed or wrong program setting. Make sure that all the
connections wires on the “J1” terminal board are installed correctly. There MUST also be a stop
button connected to J1-3 and J1-5.
Gear Reducer
If physical signs show a seal has broken in the gear reducer, it may be necessary to replace
the reducer.
When replacing the gear reducer oil, use Mobil SHC 630 or equivalent. The oil level for the
gear reducer allows gear to be dipped but not submerged in oil.
Do not overfill gear reducer oil reservoir. Reducer oil – Part #04-DUP220HT
General Reference Information
THE GATE
Double check the gate and its related hardware. Does the gate move freely? If it doesn’t, this can
affect the internal obstruction sensor.
WIRING DIAGRAM
Always reference the wiring diagram that was supplied with the operator. Note that some of the
accessory items may have their own wiring diagram.
If you cannot correct the problem or if you feel you will require technical assistance, contact your
local distributor or dealer. If you do not have a distributor or dealer, then contact us for technical
assistance. Please when calling for assistance, make sure you have the gate operator model
number, voltage, phase, horsepower and a list of all accessories that are attached to the operator.
Features and Program Troubleshooting Review
The internal obstruction sensor (r.p.m. sensor) will cause the operator to either stop or reverse if it
senses a slow down in gate speed. A damaged or poorly working gate can trip the sensor and cause
“phantom” reversing or stopping. Also if the operator’s clutch is slipping too much, this can cause the
same situation.
