INSTANT REVERSE DEVICE (IRD)
The reverse device is an internal circuit that continuously
monitors the motors current for increased draw. Turning
the IRD1 right (CW more sensitive), or left (CCW less
sensitive) in small increments will allow sensitivity
adjustments (IF ARM DOES NOT REVERSE, DO NOT
CONTINUE TO FORCE). The obstruction that you apply
should STOP the arm. Adjust sensitivity so that consistent
reversal occurs. If the gate stops while opening then the
IRD is TOO sensitive.
Some slight adjustment either way may be needed so that
the gate only reverses when obstructed. If gate is
obstructed while closing, the gate will reverse to the open
position, time out (using the time delay set at S-2 switches
1-5) and then close. If gate is opening when obstructed,
gate will stop its open travel, then will time out and close
using the same delay set at S-2.
If S-2 switch number 8 is off (you have programmed the
unit to NOT AUTO RAISE when power fails), then recheck
your adjustments with AC power off to be sure proper
operation will be maintained.
NOTES: Instant reverse device (IRD) should be tested
monthly to insure proper operation. If adjustments are
required, refer to above paragraph.
Adjustments to be done by qualified service persons only.
IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. NEVER let children operate or play with gate controls.
Keep the remote control away from children.
3. ALWAYS keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.
4. Test the gate operator monthly. The gate MUST reverse
on contact with a rigid object or stop when an object
activates the non-contact sensors. After adjusting the
force or the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator properly
can increase the risk of INJURY or DEATH.

GATE ARM INSTALLATION AND LEVELING
Install arm in gate arm bracket by lining up holes in arm with the
slotted holes in bracket. Insert the bolts through the arm and
through the bracket. Next install the flat washers then the nylon
nuts. (It is recommended the only nylon nuts be used to attach
arms).
The magnetic limit cam is pre-adjusted for near proper arm
travel, however if leveling of the arm is required this can be done
through adjustment to the magnetic cam arm. Note that limit
range can be impacted from 85 to 89 degrees by sliding the main
board up and down in its slot. Always adjust for a level arm in the
AVERTISSEMENT
HORIZONTAL POSITION. There is a small set screw in the side of
the cam arm which can be loosened to allow the cam arm magnet
to reach the close limit sensor (located on back of controller, H2)
ATTENTION
earlier or later in its travel.
Continue to open and close the gate while adjusting until a
satisfactory horizontal stopping point can be maintained.
Afterwards re-secure set screw in cam arm. NOTE: In some cases
additional adjustments may be required after the belt wears in.
When stopping in the open position, the arm will stop just before
the full vertical position.
NOTE: To prevent entrapment, allow for two (2) feet minimum
clearance past end of arm when in down position.
ADVERTENCIA
PRECAUCIÓN
5. Use the emergency release ONLY when the gate is not
moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the
owner's manual. Have a qualified service person make
repairs to gate hardware.
7. The entrance is for vehicles ONLY. Pedestrians MUST
use separate entrance.
8. Disconnect ALL power BEFORE performing ANY
maintenance.
9. ALL maintenance MUST be performed by a LiftMaster
professional.
SAVE THESE INSTRUCTIONS.
