Operation Using Your Door Operator FEATURES Your door operator is equipped with features to provide you with greater control over your door operation. myQ myQ allows you to control your door operator from your mobile device or computer from anywhere. myQ technology uses a 900Mhz signal to provide two way communication between the door operator and myQ enabled accessories. The door operator has an internal gateway that allows the door operator to communicate directly with a home Wi-Fi network and access your myQ account. THE PROTECTOR SYSTEM (SAFETY REVERSING SENSORS) When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path of the infrared beam. If an obstruction breaks the infrared beam while the door is closing, the door will stop and reverse to full open position. If the door is fully open, and the safety reversing sensors are not installed, or are misaligned, the door will not close from a remote control. However, you can close the door if you hold the button on the door control or keyless entry until the door is fully closed. The safety reversing sensors do not affect the opening cycle. For more information see page 13. ENERGY CONSERVATION For energy efficiency the door operator will enter sleep mode when the door is fully closed. The sleep mode shuts the door operator down until activated. When the door operator enters sleep mode, the sensor LEDs will turn off and whenever the door operator is activated, the sensor LEDs will light. The door operator will not go into the sleep mode until the door operator has completed 5 cycles upon power up. USING YOUR DOOR OPERATOR The door operator can be activated through a wall-mounted door control, remote control, wireless keyless entry or myQ accessory. When the door is closed and the door operator is activated the door will open. If the door senses an obstruction or is interrupted while opening the door will stop. When the door is in any position other than closed and the door operator is activated the door will close. If the door operator senses an obstruction while closing, the door will reverse. However, you can close the door if you hold the button on the door control or keyless entry until the door is fully closed. The safety reversing sensors do not affect the opening cycle. The safety reversing sensor must be connected and aligned correctly before the door operator will move in the down direction. BATTERY BACKUP (OPTIONAL) The battery backup system allows access in and out of your building, even when the power is out. When the door operator is operating on battery power, the door operator will run slower, the Battery Status LED will glow solid orange, and a beep will sound approximately every 2 seconds.
