SETTING SAFETY OBSTRUCTION FORCE

8. SAFETY OBSTRUCTION TEST
Please take care when testing the Safety Obstruction Force.
Due to Excessive forces failure to follow this warning may
cause SERIOUS PERSONAL INJURY and/or property
damage. The test below should be repeated at regular
intervals (approximately every two months).
8.1 TESTING CLOSE CYCLE
1.
Open the door by pressing the OPERATE button (
Fig. 11
)
.
2.
Place a length of timber approximately 50mm high on the
floor directly under the door (
Fig. 12
).
3.
Press the OPERATE button to close door. The door should
strike the object and start to re-open.
NOTE:
If the door stops and fails to reopen, it is possible that
the motor direction is set incorrectly. Change the motor
direction and retest.
IMPORTANT WARNING: If the test fails, there may be a
problem with the door, discontinue use, put the door into
manual operation and call for service.
8.2 TESTING OPEN CYCLE
1.
With the door closed - press the OPERATE button to open
the door. When the door is approximately one metre above
the timber hold the bottom rail of the door firmly, the door
should stop.
ADJUSTING SAFETY OBSTRUCTION FORCE
The Safety Obstruction Force is calculated automatically and
set in memory on the Shed Master. 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. If adjustments are made you must retest
the obstruction force margin as per above.
8.3 TO INCREASE FORCE PRESSURE
1.
Press and hold the Force Margin Set button (
Fig. 11
)
2.
While holding down the Force Margin button, press the
Plus button. Each press increases the force margin in both
directions. The Open Limit LED will illuminate each time
the Plus button is pressed. Each press increases the force
margin. Test the force as per step 8.1 and 8.2. If the Open
Limit LED flashes continuously when the Plus button is
being pressed, this indicates that the maximum force
pressure setting has being reached.
8.4 TO DECREASE FORCE PRESSURE
1.
Press and hold the Force Margin Set button (
Fig. 11
).
2.
While holding down the Force Margin button, press the
Minus button. Each press decreases the force margin. The
Close Limit LED will illuminate each time the Minus button
is pressed. Test the force as per step 8.1 and 8.2. 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.
FIG. 12
8.5 TO RECALL FACTORY SET FORCE
1.
While holding down the Force Margin Set button (
Fig. 11
)
press the SET button for two (2) seconds.
2.
Release both buttons. The default setting should now be
recalled.
8.6. TO RE-CALCULATE FORCE MARGIN
Press and hold the Set Button for two (2) seconds, the beeper will
sound once. The door will start to move and re-calculate force
margins. The door can move between the open and close limit
positions up to four (4) times (depending on the position of the
door and the power up condition). A single beep will be heard once
the process is complete. The door is now ready for use.
IMPORTANT NOTE:
After installation ensure that the opener stops or is
prevented from opening when the door is loaded
with a mass of 20kg fixed centrally at the bottom
edge of the door.
