No adjusting or amending is allowed to Z15.

Z15 is specialized for Camera and Lens before it leaves the factory. Please mount your camera to Z15 when get it.

No adjusting or amending is allowed to Z15. Do not modify or add any other component/device (such as filter, lens

hood, etc.) to the camera; make sure to use the original battery; otherwise it may ends up with worse performance

or even internal malfunction.

Z15 can only work with Flight control system specified by DJI Innovations (Ace One/ Ace WayPoint/ WooKong M,

make sure to upgrade the flight control system to the latest firmware version), so as to ensure the highest stability

and precision. Please download the corresponding assistant software and upgrade the flight control system MC

firmware, otherwise may lead the Z15 work abnormally.

Make sure the Flight control system operates in the safest manner when the main power battery is connected. We

strongly recommend customers to remove all propellers, use power supply from R/C system or flight pack battery,

and keep children away during gimbal calibration and parameter setup. Please strictly follow these steps to mount

and connect gimbal on your aircraft, as well as to install the assistant software on your computer. Please respect

the AMA’s National Model Aircraft Safety Code.

As DJI Innovations has no control over use, setup, final assembly, modification (including use of non-specified DJI

parts i.e. motors, ESCs, propellers, etc.) or misuse, no liability shall be assumed nor accepted for any resulting

Z15 is an excellent gimbal designed for AP. The gimbal has built-in slip ring in the mechanical structure, preventing

wire rod from winding up. It also has built-in independent IMU module, special servos drive module, HDMI- AV

module, etc. Excellent job can be done by Z15 in any working mode, including Orientation-locked control, Non

orientation-locked control and FPV Mode (Reset).

Note1: Gimbal pointing means the PAN rotation angle of the gimbal.

Note2: Attitude stability means that gimbal’s ROLL/TILT will not follows the aircraft’s ROLL/PITCH.

Note3: Gimbal rotating maximum velocity is corresponding to TX 100%end-point.

Gimbal Description

Notes:

 Ensure nothing blocks the servo driver module rotation, to avoid motor damage.  Clear obstacle at once if the rotating gimbal is blocked.

Tips:

 Servo driver module is with two motor command input ports and one encoder private port.  HDMI-AV module converts HDMI video signal to AV video signal with a cable connecting to camera

HDMI port; also transforms TX signal into shutter control signal with a shutter control module.

 The camera shutter control cable is pluggable, user can unplug it if nonuse the shutter control function.

Notes:

 Ensure to mount the side of servo driver module1 without ports to the aircraft nose direction.  Make sure the top and bottom plates of damping unit stay parallel when mounting, preventing the

damping units from stretched and distorted.

 Keep overall balance when mounting, in order to make the center of gravity on the Z axis line.  The gimbal center of gravity has been set, whose position directly determine the gimbal performance.

Please do not adjust the gimbal center of gravity by yourself.

 The gimbal is high-precision controlled. Do not remove any other screws in the gimbal, which may result

in bad performance or even damage.

necessary.

Check Before Flight

Notes:

 The gimbal is installed firmly to landing gear, and camera mounted correctly and stably.  All cables are in correct connection, without anyone in backwards.  The gimbal video power cable is in good soldered condition if wireless video transmission module used.  Correct TX settings.  Camera shutter control module is correctly mounted.  Correct camera setups.  Correct connection between GCU and RC receiver.  Normal connection between GCU and flight control system.  Upgrade Flight control System MC Firmware.

Tips:

 The gimbal LED flashing red quickly when the camera and gimbal connection fails.  The gimbal LED stays solid green when the camera and gimbal is successful connection.  Please turn to the

if abnormal situation occurs.

Test

Flight Test

step1: Ensure the batteries are fully charged for transmitter, GCU and all the other devices on your aircraft. step2: Make sure all connections and wirings are in good condition. step3: Switch on the TX. step4: Make sure to adjust the Roll axis of gimbal to be level. step5: Power on the gimbal and wait for self-testing. The Roll axis will rotate first, and then the yaw and pitch

axes will rotate quickly at the same time.

step6: After self-testing, the camera lens will point to aircraft nose direction, that is, the three axes of gimbal

should be in the condition as the above diagram shows.

step7: The gimbal goes into initialization, at this time the three axes will rotate very slowly. step8: The gimbal is at a standstill after initialization, and ready for usage. step9: Toggle the Working Modes switch on your transmitter, and make sure it is working properly.

Switch the Working Modes to Non orientation-locked, FPV Mode (Reset), Orientation-locked

respectively, and then try to push your sticks lightly in Roll, Tilt and Pan to feel if your gimbal moves to

the corresponding direction. If not, go back to the Gimbal Working mode Switch Set to correct your

settings.

Notes:

If the gimbal is abnormal (unlike the diagram shows) after initializing, please turn to the

Trouble Shooting

in

Appendix

Appendix

Matters Needing Attention

For safety reasons, please pay serious attention to all of the following items:

 Ensure nothing blocks the servo drive module’s total range of movement, to avoid motor damage.  Before powering on, spin the gimbal by hand through the complete rotational axes to ensure nothing is

blocking the mechanical movement of the gimbal.

 Be sure to mount the side of servo drive module1 with ports facing towards the aircraft’s tail.  The gimbal’s center of gravity balance has been preset from the factory. The gimbal balance is

directly correlated with the gimbal performance. Please do not adjust the gimbal’s center of gravity

by yourself.

 The gimbal is a sophisticated, highly technological device. Do not remove any other screws in the

gimbal which would result in poor performance or even damage.

 Do not unplug any cables attached to the gimbal ports or change the mechanical structure.  Make sure all wiring is correct, otherwise it may lead to abnormal operation or the gimbal may start to

operate out of control.

 Make sure to connect the wireless video transmission module to the GCU prior to powering on the

system.

 The camera’s HDMI resolution should be set to 1080i, otherwise the HDMI-AV/HD module may not

work normally.

 The factory gimbal video power cable is recommended.  Make sure you solder the gimbal video power cable to the wireless video transmission module

correctly. Ensure the cables are insulated and protected to prevent and type of short circuit.

 Pay close attention to the S800 EVO’s voltage and be sure it is within the defined limits (6S) when

using one battery for both the S800 EVO and power supply for the gimbal.

 Prevent the gimbal from ever touching the contact points of a power cable; otherwise it may lead to a

short circuit of the gimbal and cause complete failure.

 Make sure to adjust the roll axis of the gimbal to be level when the camera is attached before

powering on.
