    Mounting Hyper Quick Release

    Using 32mm square M3 pattern to mount the top part onto the frame or damping isolator.

     
     
    Connect

    STEP 1: The marks on the top part and bottom part must be aligned. The button on the ring should be aligned with the unlocked icon as shown in the first picture.

    STEP 2: Keep everything aligned and attach the bottom part to the top part.

    STEP 3: Rotate the ring clockwise until hearing a snap, the button should be automatically popped out and aligned with locked icon.

     
     
    Disconnect

    STEP 1: Press and hold the button.

    STEP 2: Rotate the ring counterclockwise.

    STEP 3: When the button aligns the unlock icon, the T3 can be detached from the top part of Hyper Quick Release.

     
     
     
  • 09. Powering Up The GREMSY T3

    After connecting to the power supply, the gimbal will perform series of alignments, self tests, which last about 5 seconds and will determine the status of the gimbal, indicated by the Status LED color. During this time, don’t touch the gimbal or camera.

    Always start the gimbal with a balanced camera set up otherwise after initialization the controller will return an error followed by a red color indicator.

     
    Step 1

    Make sure the Hyper Quick Release is mounted to the drone and its power port is already connected to the power supply correctly. Next, let’s mount the gimbal to the Hyper Quick Release, it will be automatically powered up.

     
    Step 2
    Wait about 5 seconds, do not touch the gimbal or camera.
     
    Step 3
    If the status LED is blinking green, the gimbal is ready for use. By default, the gimbal is in Follow mode if the motors are turned ON by the Function Button. Pan and tilt will hold the last orientation during turning on motor in follow mode so Tilt axis can be positioned to preferred orientation by hands.
     
    If the status LED is solid red, something is wrong with the gimbal and motors can not start. Connect to the software/apps to check details of the error message.
     
    Read “LED STATUS INDICATOR” in next section for more information.

  • 11. Operation Modes
    GREMSY T3 HAS 2 OPERATION MODES

    LOCK MODE: is a stabilization mode where the camera maintains orientation independently of the rest of the gimbal and the orientation can be changed by an external control signal from remote control.

    FOLLOW MODE: in this mode, the camera will mimic the operator’s movement and allows one person to control camera tilt and pan without using an external device like a remote control.

     
     
    GREMSY T3 Supports

    SINGLE OPERATOR: using FOLLOW mode.

    DUAL OPERATOR: a second operator can use a Remote Controller (SBUS, SPEKTRUM, PPM) to control gimbal’s movement.

     
     
    Working Operation
     

    GREMSY T3 has 2 working operations: Normal and Inverted.

     
    After powering up the gimbal , it will automatically detect if the gimbal is in inverted operation or normal operation based on pan motor position.
    During working, switching to other working operation made easy by changing pan motor position, the gimbal will automatically detect new type of working operation.
     
     
     
    Swithing Between Modes

    Using function button

    PRESS TIMES MODES
    Once time Turn motors ON
    2 times Lock mode
    3 times Follow mode
    Hold 3 seconds Turn motor OFF
    4 times Calibrate Gyros
     
     

    Using mode channel on remote control

    POSITIONS MODES
    High Follow mode
    Motors ON
    Midle Lock mode
    Motors ON
    Low Motors OFF
     
     
     

    Using software/application

    If there is a remote control signal, changing modes or turning motors on/off by other methods such as using the function button or software will not take effect because the remote control signal has the highest priority and override the command.
