Test the operator reversing sensitivity:

2
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 reverse sensitivity and repeat this testing until the correct
sensitivity has been achieved in
BOTH
directions. The operator will assume a soft shutdown (Hold the auto-close timer) after
striking and reversing the gate which will require pressing the “
Push to Operate
” button to cycle the operator again.

3.4 Inherent Reverse Sensor Adjustment
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.
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.
Note: “
Push to Operate
” button will use
Auto-Close timer if turned ON.
Note: The LED will turn
on briefly when AC
power is turned on.
CAUTION:
Keep pedestrians and vehicles clear of the gate while adjusting and testing sensors!
Safety Note:
The LED will
remain ON after a cycling gate
gets obstructed during normal
operation to indicate that the
reverse sensor has been tripped.
Always check the gate area for
possible obstructions before
putting operator back in service.
While gate is opening, slowly rotate the reverse sensor clockwise until the LED lights up
and the gate reverses direction. Rotate the reverse sensor back counter-clockwise
approximately 1/8 turn to decrease the sensitivity (LED will turn off).
Press the “
Push to Operate
” button and
CLOSE
the gate.
Make sure the gate closes completely. If it reverses and
opens (LED will turn on), rotate the reverse sensor
counter-clockwise a little more to decrease the reverse
sensitivity (LED will turn off).
Cycle the gate a few times to be sure that it cycles completely in both directions,
adjusting the sensor as necessary.
Press the “
Push to Operate
” button to
OPEN
the gate.
