8.3.4. Safety Force testing
8.3.4.1. Testing open direction safety obstruction force value (Adaptive Mode)
1. With the garage door in the fully closed position, stand in the middle of the garage
doorwayandjustbehindthepathofthegaragedoor.
2. Activate the SDO4 so that the garage door begins to open.
3. When the garage door has opened to approximately 450mm from the ground, apply
somermdownwardforcetooneofthestructuralmembersofthegaragedoor.
4. If the safety obstruction force value is correct, the SDO4 will stop the garage door
upon sensing the applied force (safety stop). If too little or too much force is required
to make the SDO4stop-Adjustthesafetyosetasrequired(RefertoSection
9.2.3.1.).
8.3.4.2. Testing closed direction safety obstruction force value (Adaptive Mode)
1. With the garage door in the fully open position, stand in the middle of the garage
doorwayandjustbehindthepathofthegaragedoor.
2. Ensurethattheclosedlimittraveladjustmenthasbeensetsothatbottomofthe
garage door rests against the ground.
3. Place a 32mm thick block of wood under the line of the garage door (approximately at
the midpoint of the garage door) so that the garage door will close onto the block of
wood.
4. Activate the SDO4 so that the garage door begins to close.
5. If the safety obstruction force value is correct, the SDO4 will stop and reverse the
direction of the garage door upon encountering the block of wood (safety reverse).
6. If too little or too much force is required to make the SDO4safetyreverse,-Adjust
thesafetyosetasrequired(RefertoSection8.3.3.).
8.3.5. Automatic re-learn
• A re-learn of drive force and run time parameters will be automatically initiated
immediately subsequent to any of the following occurrences;
• Run time deviation becoming excessive
• Safety reversing on three consecutive occasions
• Safety stopping on three consecutive occasions
• Duringthisperiod,theLEDindicatorwillquickash,andthedisplaywillshow“rL”
COMMISSIONING THE SYSTEM SECTION 8
8.3.3.2. Set Safety Oset Value to Maximum
• For installation where maximum power and less sensitivity is required –
• SettheSafetyOsetValueto“F5”
• If F5 is still too sensitive, set Full power mode to On. Refer to menu
With Safety Oset set to Maximum, the door is dangerous and it is
recommended that Safety Beams be used.
