ADJUSTMENT

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH:
1. READ AND FOLLOW ALL WARNINGS AND INSTRUCTIONS.
2. ALWAYS keep remote controls out of reach of children.
NEVER permit children to operate or play with door control
push buttons or remote controls.
3. ONLY activate a door when it can be seen clearly, it is
properly adjusted and no obstructions exist in the path the
door will travel.
4. Personnel should keep away from a door in motion and
ALWAYS keep a door in sight until completely closed. NO
ONE SHOULD CROSS THE PATH OF A MOVING DOOR.
5. NO ONE SHOULD GO UNDER A STOPPED OR PARTIALLY
OPENED DOOR.
6. If possible, use the manual release handle to disengage a
door ONLY when a door is CLOSED. Weak or broken springs
or an unbalanced door could result in an open door falling
rapidly and/or unexpectedly causing SEVERE INJURY or
DEATH.
7. NEVER use manual release handle unless the doorway is
clear of persons and obstructions.

LIMIT ADJUSTMENT

1
Begin with the door in the fully closed position to set the
CLOSE limit.
2
Depress the retaining plate (1) and move the limit nut to the
CLOSE limits (2).
NOTE: The Close Limit Switch (CLS) and Sensing Limit Switch
(SLS) LEDs on the logic board shine when the switches are
activated and the power is on.
NOTE: The SLS is preset in the factory to engage when the door is
moving in the closing direction and the door height is less than 6"
from the ground. The purpose of the SLS is to STOP the closing
of the door when a Primary Monitored Entrapment Protection
Device is activated while the door is closing and the door is within
the noted SLS activation range. This prevents nuisance door
reversals that are attributed to a Door Edge device that contacts
the floor while the door is located at its CLS position.
NOTE: The activation range of the SLS is not adjustable in the field.
NOTE: L5 Operator Models previously utilized a physical SLS.
Later versions of L5 Operator Models achieve this SLS function
through electronics that are built into the L5 Logic Board. The
presence or absence of a physical SLS is readily visible.
3
When the retaining plate is released, verify the retaining plate
is fully seated with the notches of the limit nuts.
4
Open the door fully and set the OPEN limit (3).
NOTE: The Open Limit Switch (OLS) LED on the logic board will
illuminate when the switches are activated and the power is on.
5
When the retaining plate is released, verify the retaining plate
is fully seated with the notches of the limit nuts.
Adjustment

IMPORTANT SAFETY INSTRUCTIONS

8. After ANY adjustments are made, the entrapment protection
device(s) MUST be tested. Failure to adjust the operator
properly may cause SEVERE INJURY and DEATH.
9. Entrapment protection device(s) MUST be tested every
month. Failure to adjust the operator properly may cause
SEVERE INJURY and DEATH.
10. ALWAYS KEEP DOOR PROPERLY BALANCED. An
improperly balanced door may NOT reverse when required
and could result in SEVERE INJURY or DEATH. See the door
manufacturer's owners manual.
11. ALL repairs to cables, spring assemblies and other
hardware, ALL of which are under EXTREME tension, MUST
be made by an Authorized Service Technician.
12. ALWAYS disconnect electric power to the door operator
BEFORE making ANY repairs or removing covers.
SAVE THESE INSTRUCTIONS .
13.
NOTE: Upon power cycling (Off/On) while the door is located at
a position other than the OLS or CLS (midstop, for example) and
following setup or adjustment of the OLS/CLS limits, one complete
cycle (OPEN/CLOSE) of the operated door is required to learn/
relearn the SLS position. If a Door Edge Device is present, a door
reversal may be experienced at the end of this initial setup cycle.
The SLS will now prevent future unintended reversals.
NOTE: In some installations, such as through-wall-installation, the
rotation of the motor and logic board may have to be changed.
1. Locate the MOTOR DIRECTION jumper on the logic board.
2. Remove the CLOSE/OPEN decal and reattach appropriately.
To avoid SERIOUS personal INJURY or DEATH from
electrocution:
• Disconnect electric power BEFORE performing ANY
adjustments or maintenance.
• ALL maintenance MUST be performed by an Authorized
Service Technician
