3.4 Inherent Reverse Sensors Adjustment
Test the operator reversing sensitivity:
Press the OPEN button on the 3-push button to open the gate.
After opening gate reaches full speed, slowly rotate the OPEN reverse sensor clockwise until the
LED lights up and the gate reverses direction. Rotate the OPEN reverse sensor back counter-
clockwise approximately 1/8 turn to decrease the sensitivity (LED will turn off). The gate will
assume a soft shutdown and the CLOSE button will need to be pressed to cycle the operator.
Press the CLOSE button on the 3-push button to close the gate.
After closing gate reaches full speed, slowly rotate the CLOSE reverse sensor clockwise until the
LED lights up and the gate reverses direction. Rotate the CLOSE reverse sensor back counter-
clockwise approximately 1/8 turn to decrease the sensitivity (LED will turn off). The gate will
assume a soft shutdown and the OPEN button will need to be pressed to cycle the operator.
Cycle the gate a few times to be sure that it cycles completely. The current sensor may
need to be adjusted (9530 - 208/230 VAC models only) if gate will not reverse properly
(See 3.5 below)

Place an immobile object along the gate path, allowing the gate to strike it while in the open and close cycles. The gate must
reverse direction after striking the object. If it does not, increase the OPEN and CLOSE reverse sensitivity (steps and )
and repeat this testing until the correct sensitivity has been achieved in BOTH directions. The operator will assume a soft
shutdown after striking and reversing the gate which will require a OPEN or CLOSE button command to cycle operator again.

3.5 9530 - 208/230 VAC Current Sensor Adjustment
The 9530 - 208 and 230 VAC gate operators use a current sensing device to detect any obstructions in the path of the opening
or closing gate. The current sensor uses a sensing coil with a given number of turns through it to monitor the current flow into
the operator. Each time the wire passes through the coil, it is considered a turn. The number of turns through the sensing coil is
dependant on the operating voltage of the operator, the speed of the gate and the weight of the gate.
In general, light weight gates may require additional turns of wire through the current sensor, while heavier gates may require
less turns. In addition, the speed of the gate can affect how the current sensor works. Gates running at a higher speed may
require less turns of wire through the sensor. CAUTION – HIGH VOLTAGE: Be sure power is turned OFF before changing the
number of wire turns to the current sensor. If you are setting the reverse sensors (section 3.4 above) and reach the full sensitive
position without activating the reversing function, add an additional turn of wire through the current sensor. If you are decreas-
ing the sensitivity and the gate will not run properly, reduce the number of turns through the current sensor.

This vehicular gate operator is equipped with an inherent adjustable reversing sensor (Type A) used as the primary entrapment
protection system according to UL 325 standards. The gate will reverse direction after “physically” encountering an
obstruction in either the opening or closing gate cycle.
If the Auto-Close Timer (DIP-switch SW 1, switch 2) is ON and the gate physically encounters an obstruction during the
CLOSING cycle, it will reverse to the open position and HOLD the gate at this position (Soft shutdown condition). Another input
command is needed before the gate will reset and close again.
If the Partial Open Feature is being used and the gate physically encounters an obstruction during the CLOSING cycle, the gate
will only reverse to the FULL open limit switch setting and NOT the partial open setting.
For the reverse system to function correctly, the gate must be properly installed and work freely in both directions and the limit
switches must be properly adjusted before adjusting these sensors. The ideal adjustment will allow the operator to move the
gate through its entire travel cycle without reversing, but will reverse upon contact with an obstruction with no more than 40
Lbs of force. This force can be measured with a gate scale, P/N 2600-225.
