LGJ LIMIT SWITCH ADJUSTMENT

IMPORTANT NOTE: To avoid danger of possible damage to the door and operator, limit switches must be

adjusted to their approximate positions before applying power to the operator.

NEVER PLACE HANDS OR TOOLS INSIDE

OPERATOR OR NEAR MECHANISM UNLESS

POWER IS OFF!!

WARNING

CAUTION

WARNING

A. Set Limit Direction Switch

Open the cover on the electrical enclosure and locate

dip switch SW1 on circuit board. The direction of the

limit travel is determined by the switch SW1 - pole #2

setting.

If your operator is mounted Motor Side Up:

Set dip switch SW1 - pole #2 to “ON” position.

If your operator is mounted Motor Side Down:

Set dip switch SW1 - pole #2 to “OFF” position.

NOTE: See Mounting Options on page 5 to verify the

correct mounting application.

As determined by SW1 - pole 2 setting above, locate

your OPEN and CLOSE limit switches. See the figure

below for switch layout.

For Motor Side Up Mounting: Limit switch -A- is the

OPEN limit. Limit switch -B- is the CLOSE limit.

For Motor Side Down Mounting: Limit switch -A- is

the CLOSE limit. Limit switch -B- is the OPEN limit.

Auxiliary limit switches to control other functions are

also present and should not be confused with the -A-

and -B- limit switches. There are two(2) limit nuts on

the threaded shaft that transverse the shaft as the

operator opens and closes the door. When a limit nut

nears the end of the shaft, it activates a switch(es).

B. Manually raise the door to a nearly open position.

(see page 17, Manual Operation)

C. Depress the limit nut retaining bracket away from

the slots in the limit nuts, and manually rotate to the

OPEN limit nut until it depresses the OPEN limit

switch lever (you can hear the switch click when the

switch contacts transfer). Release the retaining

bracket and be sure it engages in the slots of both

limit nuts.

D. Manually lower the door to a nearly closed

position, and repeat step C with the CLOSE (right)

limit nut.

E. Test Limit Travel

Manually move the door to a half-open position to

avoid damage due to incorrect (dip switch setting)

limit travel. When power is applied, it will cause the

door to OPEN when the limit nuts are traveling in the

direction of the CLOSE limit switch or vice versa. In

either instance, the limit nuts will travel past the limit

switch and may cause damage to both the door and

operator. See Step A for correct setting.

F. After completing the wiring connections on pages

11 thru 13, refer back to step C above for adjustment

of limit switches to their final, exact position.

If you operator is mounted Motor

Side Up: Set dip switch SW1 - pole

#2 to “ON” position

If your operator is mounted

Motor Side Down: Set dip switch

SW1 - pole #2 to “OFF” position.

When SW1 - pole 2 position is

“ON”: Limit switch -A- is the OPEN

limit. Limit switch -B- is the close

limit.

When SW1 - pole 2 position is

“OFF”: Limit switch -A- is the

CLOSE limit. Limit Switch -B- is the

OPEN limit.
