10.6. Safety Reverse (pr)
• Partial safety reverse ensures that the garage door does not open fully and thereby
present an unwanted security risk.
• ON - The door partially reverses on detecting obstruction
• OFF – The door fully reverses on detecting obstruction
• Intheeventthatthegaragedoorencountersasucientobstructionduringaclose

afterthreeseconds.Uponreceivingasignalimmediatelysubsequenttopartialsafety
reverse, the SDO4 will recommence movement in the open direction
10.4.2. Shutdown Mode
• In the event of a prolonged power outage, the SDO4 will automatically shut down in
order to conserve the remaining charge in the batteries, and prevent battery damage.

• Shutdown will occur when the power is not active and once battery voltage falls below
23.5V
• If the SDO4 is triggered while in Shutdown Mode, the Buzzer will beep three times to
indicate Shutdown Mode and the operator will not operate
