6.8 Testing & Setting Safety Obstruction Force
6.8.1 Testing the Close Cycle
a.
Press the OPERATE button to open the door
(Fig.6.8.1)
.
b. Place an object approximately 1-1/2”(38mm) high (or a 2”x 4” board laid
flat) on the floor under center of garage door opening
(Fig.6.8.2)
.
c.
Press the OPERATE button to close the door.
d. When door contacts the object, the door must stop (within 2 seconds) and
reverse to open position.
If the door does not properly reverse.
•
Check the “close” limit position. It should not have reached its “close” limit
before hitting board.
•
If the door STOPS but does not reverse, decrease FORCE (refer to
Section
6.8.4)
.
6.8.2 Testing the Open Cycle
a.
Press the OPERATE button to close the door
(Fig.6.8.1).
b. Press again to open the door. When the door is reaching half of the opening
distance, grab the bottom rail of the door firmly, the door should stop.
If the door does not stop when opening, the force may be excessive and need
adjusting, refer to
Step 6.8.4
.

IMPORTANT WARNING! If the door is closing and is unable
to re-open when obstructed, discontinue use. Do not use a
door with faulty obstruction sensing. Repair fault and re-test
before using.
CAUTION: Take care when testing the safety
obstruction force. Excessive force may cause serious
personal injury and/or property damage can result
from failure to follow this warning.

Adjusting Safety Obstruction Force
The safety obstruction force is calculated automatically and set in memory on the
operator. It is usually not necessary to adjust the safety obstruction force. The only
time the force may need to be increased is due to environmental conditions, for
example, windy or dusty areas, and areas with extreme temperature changes.
6.8.3 To Increase Force Pressure
a.
Press and hold the FORCE MARGIN SET button
(Fig 6.8.3)
.
b. While holding down the FORCE MARGIN SET button, press the Plus (
+
)
button. Each press increases the force margin.
c.
The Open Limit LED will flash each time the plus button is pressed to
indicate an increase in force.
d. If the Open Limit LED flashes continuously when the plus button is being
pressed, this indicates that the maximum force pressure setting has been
reached.
e.
Test the force again as per
Section 6.5.1
and
6.5.2
above.
Fig.6.8.3
WARNING! Risk of entrapment. After adjusting either the
force or limits of travel, retest the door opener. The door
MUST reverses on contact with a 1-
1
/
2
-inch high object (or a
2 by 4 board laid flat) at the center of doorway on the floor.
6.8.4 To Decrease Force Pressure
a.
Press and hold the FORCE MARGIN SET button
(Fig
6.8.3)
.
b. While holding down the FORCE MARGIN SET button,
press the Minus (
-
) Button. Each press decreases the force
margin. The Close Limit LED will flash each time the minus
button is pressed.
c.
If the Close Limit LED flashes continuously when the minus
button is being pressed, this indicates that the minimum
force pressure setting has been reached.
d. Test the force again as per
Step 6.8.1
and
6.8.2
above.
6.8.5 To Recall Factory Set Force
a.
While holding down the
FORCE MARGIN SET
button,
press the SET button
(Fig 6.8.2)
for two seconds.
b. Release both buttons. The default setting should now be
recalled.
AVERTISSEMENT IMPORTANT! Si la porte est en train de se
refermer et ne peut pas être rouverte, arrêtez de l’utiliser.
N’utilisez pas une porte dont les détecteurs d’obstacles sont
défectueux. Réparez-les et refaites un essai.
AVERTISSEMENT! Risque de pincement. Après avoir réglé
la force ou les fins de course, refaites un essai du système
d’ouverture de porte. La porte doit OBLIGATOIREMENT
inverser sa course en cas de contact avec un objet de 25 à
40 mm (1-1/2’’) (ou une planche de 5 x 10 cm posée à plat) au
milieu du passage.
ATTENTION: Testez la résistance aux obstacles avec
précaution. Une force excessive présente un risque
de blessure corporelle grave et/ou d’endommager le
matériel si vous ne respectez pas cet avertissement.
