QS-BT1
User manual for QS-BT1.
1 Introduction
QS-BT1 is a multi-purpose, dual-channel, direct-drive seat belt tensioner that increases the immersion of a racing simulator. It is powered by the same technology as QS-220 and provides force feedback similar to that offered by direct-drive wheels. QS-BT1 generates vibrations to simulate a running engine, tensions up with downshifts, upshifts, in corners, and finally - gives a strong pull when crashing. Importantly, it can also work as a standalone, fully independent device.

4.8 Seat belt settings
4.8.1 Seat belt setup
For your comfort and the best simulation experience, the seat belt must be set up correctly (racing harness not included).
2. All tongues of the seat belt should be fastened to the buckle, as shown in the picture.
1. Correct seat belt tension can be determined by placing your hands underneath the belts. If your hands can move freely - tighten the belt. If you cannot put your hands under the belt - loosen the belt.

Info
For the most realistic and immersive experience, seat belts should be horizontally positioned with the same width as your neck width. If the belts are positioned too wide or too narrow, pain or scratches in the neck area will occur.

4.8.2 Vehicle vs. flight simulations setup
Info
To have the most immersive experience in vehicle or flight simulations you need a compatible seat with specific seat belt slots height.
In vehicle simulations you should have horizontal pulling force instead of upward or downward pulling force. Seat belt slots should be at the same level as your shoulders.

In flight simulations you should have downward pulling force instead of upward or horizontal pulling force. Seat belt slots should be positioned lower than your shoulders.

4.8.3 Attaching tensioner buckles to the harness
QS-BT1 's Tensioner Buckles should be mounted to your seat belts (harness) using included Belt buckles and fasteners. Use seat inserts for the holes in your racing seat.

Info
Illustration of a finished belt buckles assembly.


Info
When reinstalling a previously used device, ensure that the belts are correctly extended (unrolled from the inside).
Warning
All operations MUST be performed with the power OFF.
Tip
Order of operations:
- Attach the racing harness to a cockpit and adjust it for the user (section 4.8.1). QS-BT1 must be attached to an already correctly setup racing harness.
- Attach the fully extended tensioner buckles to the harness, leaving a minor slack. It is suggested to clamp the harness with belt buckles without torquing the bolts, then check the setup again.
- While tightening the bolts, keep the belt buckles pulled upward to prevent them from lowering during installation. Refer to the belt tightness illustration for a visual example of the desired result (belt tightness illustration).
- Run your seat belt through the belt buckle and mount it with QS-BT1 's tensioner buckle. Start from screwing in top bolts, then proceed to the ones below. Ensure they are perpendicular to the belt.
Before screwing the bolts down ensure proper tightening of the belts.
QS-BT1 's belts should a minor slack - do not force them tight, since they will be tensioned later by the QS-BT1 after in-game engagement (for more details go to section 6).

- Refer to the illustration on the right for a correct belt intertwine between belt buckle bars longrightarrow Ensure correct mounting of the tensioner and belt buckles as this may have negative impact on device's performance and user's feeling of immersion. The belt tensioner generates a maximum of 200 N of force on each side. Install adjustable seat belts that can withstand forces generated by the device, preferably with FIA certification.
InfoRevision A (prototype) and B of the QS-BT1 are using respectively 6 and 5 (instead of 4) assembling bolts and different type of belt buckle (with different assembly hardware):
- QS-BT1 's Tensioner Buckles should be mounted on the same level and evenly in relation to each other - parallel to the QS-BT1 's main unit.

- Excess belt should be rolled and attached permanently to rest of the harness. It cannot interfere with platform movement.
- Attach the fully extended tensioner buckles to the harness, leaving a minor slack (without forcing the belts upward). The racing harness should be tight. Heavily sagging QS-BT1 's belts will reduce the feedback on details.

- If necessary, the device can be installed further away. Preferably the assembling method would ensure that the belts are perpendicular to the device. Maximum angle of belt inclination is 45 degrees.
If the belts rub against the housing while in normal operation - the pulling force will significantly drop, reducing the immersion.
WarningIn case of motion platform implemented cockpits - the QS-BT1 always MUST BE mounted to a position that is moving along with the seat. In order for QS-BT1 to work correctly it is recommended that it always is mounted directly to a cockpit and not separately.
4.8.4 Seat inserts
Info
Seat inserts are provided with the QS-BT1 mainly to reduce friction on the harness. They also guide your belts better, prevent the seat from getting worn down and reduce the sound of harness rubbing against the harness slots.


Info
User may use an alternative solution for smooth harness operation, e.g. aftermarket rollers. However - minimum recommended roller diameter is no less than 35 mm. Small diameter will cause bigger bend angle on the harness and will restrict tensioning force for the user, thus lowering the immersion.
4.9 Cable connections
Warning
Power cords used to power QS-BT1 or other devices MUST NOT run alongside the QS-BT1 's USB cable. They MUST be separated to allow for reliable connection with the PC.
4.9.1 Before connecting Power
Warning
The operation of connecting cables must ALWAYS be carried out with the power switched OFF.



4.9.2 Basic connection diagrams


Warning
If QS-BT1 is not included in Motion Lock circuit, then Motion Lock jumper MUST be plugged in, as shown in the illustration below.

Info
- QS-BT1 supports a USB connection via cable with a MAXIMUM length of 3 meters between the device and a PC. Do not use a USB extension cable.
- If necessary, use only high-quality powered USB hubs. For reliable operation, use a short USB cable (less than 1 metre) and connect through a powered hub.
Info
To ensure safe power disconnection from QubicSystem device power supplies, it is recommended to use an external power switch — such as a power strip with a switch or a smart plug (rated for min. 10A).

- In a racing simulation the QS-BT1 will tension the belts (depending on a game) after firing the engine, first braking or a downshift action.
- In a flight simulation the QS-BT1 will tension the belt (depending on a game) after sudden braking on a landing strip or a sudden control stick movement while in the air.
- Anytime you pause or exit the game the QS-BT1 will release the tension of the belts.
- After you resume the game the QS-BT1 will tension the belts again after any action from point 6 (a) or 6 (b) will occur.
7 Troubleshooting
Warning
DO NOT attempt to do any repairs by yourself. It is dangerous and will result in loss of warranty! All repairs should be consulted with technical support and performed by a qualified technician.
- Check the Action Center in QubicManager.
- Open the diagnostic window to check if the device is responsive.
- Select Tools and Diagnostic → Seat Belt Tensioner Diagnostic

- Diagnostic window allows pulling belts by using the sliders. It also displays the input data signal from the application.

- Select Tools and Diagnostic → Seat Belt Tensioner Diagnostic
- Check all cable connections of the device. Refer to section Cable connections.
- Restart QubicManager application by right-clicking on the application icon in the system tray and selecting Restart

- Try different USB ports in your PC.
- If a problem occurs abruptly, it could be caused by thermal protection. Turn off QS-BT1 , disconnect it from power outlets and wait at least 15 minutes to let it cool down.
- In case of any unclear electrical issues or strange behavior, contact technical support.
- If the device suffers from abnormal work conditions, please immediately contact the distributor/reseller for technical support.
Info
If none of the diagnostic advice listed above works, create a snapshot. It compiles all the necessary details for technical support to resolve the issue.
7.1 Common problems with solutions
- Problem: Belts do not release/belt release is weak.
First verify if user's profile is causing the no-release problem - constant flow of game inputs may be making the belt tension without stop. To verify that:
- Go to QubicManager → "Tools and Diagnostics" (1) → "Seat Belt Tensioner Diagnostic" (2).
- Open and enlarge the "Seat Belt Tension [%]" (3) graph.
- Right-click on it → "Stay on top" (4).

- Check if lines ever go down to 0 during normal game session.
Solution #2: If the lines go down but belts do not release - harness/belt's friction is too high. Since the force of the belt tension is regulated by the motor, but the release of the belt is not, user must ensure the least possible friction on the harness and built-in belts. QS-BT1 must be mounted according to the manual (section Correct belt angles, p. ). Low friction inserts must be installed (or possibly aftermarket roller setup - more info in section 4.8.4, p. ).

- Problem: Belts are not working symmetrically/one belt is weaker.
First verify that belts have symmetrical pulling force.
While the QS-BT1 is ON and the user is sitting in the rig with belts fastened:
- Go to QubicManager → "Tools and Diagnostics" (1) → "Seat Belt Tensioner Diagnostic" (2).
- Open and enlarge (double-click) the "Seat Belt Current [mA]" graph (3).
- While observing the graph (4), move the slider "Belt Tension Both [%]" (5) slowly to the right and back to the left. Focus and feel whether the right and left belt pulls with the same force (small oscillations on graph are normal due to uneven mouse movement).

- there is too much friction on one of the sides
- the harness is installed incorrectly (unevenly, bolts not torqued down)
- the harness is coming loose on the chest adjusters
- QS-BT1 is not installed in vertical center axis of the seat which causes the belts to slip to the side and rub against the seat harness slot
Solution #2: If two lines clearly do not match each other - report the problem to Technical support via application form on the Motion Systems website, including a snapshot file (section 7.3). Solution #3: If there is no pulling force on one of the belts and the device is emitting unusual noises - report the problem to Technical support via application form on the Motion Systems website, including a video of a working QS-BT1 .
- Problem: QS-BT1 does not calibrate at start-up.
Solution: QS-BT1 does not have a calibration procedure. Once the belts are fully extended and the device is connected according to the diagrams - it is ready to operate. Once in the game/simulation - the first input signal sent to the QS-BT1 will start tensioning the belts (for details on operation of the device, go to section 6, p. ).
- Problem: QS-BT1 keeps disconnecting/does not connect at all.
Solution #1: Make sure QubicManager software is up to date. Go to QubicManager → "Tools and Diagnostic" (1) → "About / Support" (2) → check the software version (3)
Compare it to newest software version listed on Qubic System website: QubicSystem.com/qschangelog → "Software" → "Changelog".
Solution #2: Check Action Center in QubicManager for pending issues. Click "Resolve all" button if there are any issues or resolve them one by one.
Solution #3: Pass over the USB Hub - connect the device directly to the PC. Solution #4: Plug the QS-BT1 to a different USB Port. Solution #5: Replace the original USB cord (Type B USB plug).
Solution #6: Separate power cords from QS-BT1 's USB cable so that they do not run alongside each other.
If none of the solutions above work - report the problem to Technical support via application form on the Motion Systems website and include a snapshot file (section 7.3).
To avoid any potential problems or damage to equipment NEVER disconnect or connect the Power Supply plug to the QS-BT1 with Power ON. For details - go to section 4.9.1.
- Problem: QubicManager software crashes on launch with an OpenGL error.
Solution short-term: To open the app, click OK on all the operating system errors. Restart the QubicManager software and you will be presented with a window:
Click "YES" if you want run the application in Safe Mode (it will run a little slower). Solution long-term #1: In order to overwrite the OpenGL rendering backend permanently, type in troubleshooting in Windows search bar. Select Qubic System Troubleshooting Assistant.


In the prompt window, type 6 on your keyboard and click Enter. Restart the QubicManager application.Solution long-term #2: This issue is caused by graphics drivers. Try to downgrade to a previous version of graphics drivers or check for updates.
- Problem: QS-BT1 does not work when the car hits rumble strips/curbs.
Solution #1: To verify that QS-BT1 is working correctly try a different game/simulation. It is possible that different games/simulations will provide QS-BT1 with different data.
Solution #2: Activate a default game profile (2) (always the first one in a given game title list (1)) and bring all the sliders to a default setting by clicking "Default" button (3) and then "Yes to all".

Solution #3: Increase Rumble strips/Road harshness slider value.Tip: If QS-BT1 is working correctly and only the rumble strips/curbs are not present - most likely it is the lack of input from the game. To verify what input signal is being sent to any QS device - go to your currently activated game profile → "Input diag." and watch the graphs during typical game session. Double click to open in a new window -> right click on a graph -> Stay on top. Illustration of a "Kerb Vibration" graph after hitting a rumble strip:
