3.4 Inherent Reverse Sensors Adjustment
Test the operator reversing sensitivity:
Press the OPEN button on the 3-push button to open the gate.
While gate is opening, slowly rotate the OPEN reverse sensor clockwise until the gate reverses
direction. Rotate the OPEN reverse sensor back counter-clockwise approximately 1/8 turn to
decrease the sensitivity. 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.
While gate is closing, slowly rotate the CLOSE reverse sensor clockwise until the gate reverses
direction. Rotate the CLOSE reverse sensor back counter-clockwise approximately 1/8 turn to
decrease the sensitivity. 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 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.

This vehicular gate operator is equipped with an inherent adjustable reversing sensor (Type A) that is used as the primary
entrapment sensing system according to the UL 325 standards. The gate will reverse direction upon encountering an obstruc-
tion in either the
opening or closing gate cycle.
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.
CAUTION: Keep pedestrians and vehicles clear of the gate while adjusting and testing sensors!
3.5 Current Sensor Adjustment
This vehicular gate operator uses 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.
