Precautions and dynamometer safety

Your dynoKRAFT engine dyno is a safe and proven way to test the engines performance in a repeatable test conditions.
To assure problem free operations you should note these precautions and use common sense at all times!

Engines exhaust gasses

Always assure proper dyno room ventilation and use engine exhaust extraction system which is adequately scaled to remove all exhaust gasses from the room in which people are working in.
Fail to do so may result in serious hazard to dyno room operators and will impact engine’s performance.

Warning!  Carbon monoxide / Toxic gasses ! 
Combustion engine exhaust gasses contain toxic carbon monoxide. Breathing it can cause death.
Always operate the dynamometer in well ventilated area. Always use exhaust gasses extraction system during test runs.

Noise and debris

Keep in mind that running an engine test at high RPM and Load will create a noisy work environment which may affect one’s ability concentrate on task he’s performing. Prolonged exposure to noise may result in head ache or nausea.
Always use eye protection to avoid eye damage from any debris or dirt which may be found in the air either because of extensive room ventilation or due to equipment damage.

Warning!  Excessive noise / Eye damage.
Always use eye and ear protection while working with dynamometer. Fail to do so may result in serious health issues, hearing loss or visual impairment.

Rotating parts

All rotating parts are potential source of serious accident. Therefore always operate the dynamometer with all coverings properly installed. Use additional covering or protection to secure any visible parts of the engine or dynamometer. Always ware tight sleeves to avoid getting dragged by any rotating parts.

Warning!  Rotating parts.
Never operate an dynamometer without properly installed coverings. Always use cloths with tight sleeves.
Fail to do so may result in getting dragged by rotating parts or components.

Heat

During an dynamometer test and substantial amount of heat will be generated by both the engine and dynamometer equipment. The air temperature in the dyno room will rise gradually.
Additionally some surfaces of the combustion or electric engine may get very hot.

dynoKRAFT is encouraging dynamometer operators to use an infrared thermometer to check if the surface temperatures are in safe range. Temperature above 55°C is considered harmful.

Warning!  Hot surfaces.
Avoid touching of hot surfaces during and after the dynamometer tests.
Some areas of combustion engines such as exhaust system can get extremely hot and touching them may cause severe tissue burn.

Electric power. Compressed air

The dynoKRAFT dynamometers are operated using electric power and compressed air.
Do not remove any covering panes, perform any service or repairs or open any electric cabinets under power.

Any repairs or service which requires accessing the dynamometers electrical system must be performed by qualified electrician.

Warning!  Potentially lethal voltages.
Never perform any service or remove any protective panels or open electric cabinets without previously disconnecting the main AC power cord.
Always wait min. 5 minutes after turning off the dynamometer main switch to allow for complete discharge of electromagnetic coils of the Eddy Current Brakes.
Fail to do so may result in lethal electric shock.

Before performing any service operation or repairs to pneumatic components always release the pressure from the pneumatic system. Please follow service procedures described below on details how to release the pressure..

Warning!  Eye damage.
Always use eye protection while working with dynamometers pneumatic systems.
Fail to do so may result in serious eye damage and visual impairment.

General precautions

Always keep minimum safe distance while working with dynamometers so that in case of equipment or engine failure, fire or other hazard the risk of accident is minimized.
Excessive noise or vibration of dynamometer usually indicates serious fault and should be directly solved.

Always verify emergency brake operation before using your dynamometer.
Before performing any tests always verify if the dynamometer and vehicle you’re about to test are properly secured.

Ensure that both the dynamometer and vehicle you’re testing are sufficiently cooled.

Never perform any servicing of the dynamometer unless explicitly recommended in manual..
Caution. Risk of equipment damage. Potential safety hazard.
Not obeying to these rules may result in equipment damage, potential safety hazard to dynamometer operators and can result in loss of warranty.

Dynamometer installation and commissioning

Installation and commissioning

The test stand must be installed on a solid concrete floor with sufficient load-bearing capacity (min. 2 T / m²).
The floor should have a flatness of 2 mm per 1 m (or better). Installation of the pit is usually possible without any further changes to the roller set when using pit-kit (ordered separately)
Please contact dynoKRAFT for a dimensional drawing of the pit.

Installation and commissioning can only be carried out by a dynoKRAFT technician.
EMC noise.  To avoid excessive noise during data transfer, please keep the USB connection / cable between ADAQbase and the computer as short as possible.

Setting up your workspace

Please setup your workspace so that at least one emergency stop button is within your range at all times while working with your dynamometer / while sitting in the vehicle.

Connecting to Electric Power Supply and Compressed Air Supply

Please connect a power cable to dynamometer main power inlet “MAINS” using adequate extension cable.
Please make sure to use proper electric power source matched to the electric system of the dynamometer.
If in doubt please check the machine label for information on power system used and consult licensed electrician.

The test bench must be connected to a suitable Type-B residual current circuit breaker, followed by a three-pole 32A fuse, to the mains.

Warning! Obligatory u se of residual current circuit breaker.
A residual current circuit breaker Type-B is an obligatory part of the electrical connection of the dynamometer. Failure to comply with this rule can result in severe electric shock or death, e.g. if the insulation is damaged! If the test stand is operated without a residual current circuit breaker, the guarantee expires!

Please connect a suitable compressed air hose to the compressed air inlet adapter. The inlet is a standard 7.4mm workshop quick connector normally found in auto repair shops.
To switch on the dynamometer, please turn the main switch on the side of the switch cabinet to the ON position.

Dyno room

Noise control. Dynamometer room requirements

dynoKRAFT is recommending to setup your dynamometer in noise control room. It is not uncommon, that during combustion engine testing under full load and high RPM the generated noise level is in excess of 110dB

Another important requirement is flammability resistance of your dynamometer room and any equipment you will install inside the room. 
The room must also consist of emergency exit wired to the e-stop circuit of your dynamometer. Please consult your local health and safety requirements.

Ensure minimum work space around the dynamometer-test engine setup. dynoKRAFT is recommending a minimum of 2 meters around the dynamometer and engine to allow easy access to all controls and equipment.

Fire hazard

Please ensure that there are a sufficient number of suitable fire extinguishers in the dyno room.
If in doubt, speak to your local health and safety requirements authorities or fire department.

Basic dynamometer operation

E-Stop procedure and reset

The following steps / functions are carried out while the emergency stop button (emergency OFF button) is pressed:
- the air pressure is released from the pneumatic brake system and the emergency brake is applied
- the test stand is switched off

To reset the dynamometer after emergency stop event into normal operation mode please follow these steps:
- Examine the engine and dynamometer and fix any issues with the setup
- Investigate the room for potential hazard
- If you’re not able to identify any potential hazard please release all e-stop buttons and press the “RESET” button


Caution.
Should the emergency stop procedure be triggered from a driving speed of over 200 km / h, the test bench must be serviced by a dynoKRAFT technician before it can be used again.
Otherwise no safe operation can be guaranteed.

Fixing of the vehicle

dynoKRAFT is expressively discouraging users to ride on the motorcycle while loading it onto the dynamometer!
Any damage to equipment or operator caused by such action is not covered by warranty!

To fix an motorcycle or other vehicle on your dynoKRAFT dynamometer please follow these steps:
1. Please power up all systems and activate emergency stop by pressing e-stop button. This will lock the roller and ease the loading of the vehicle on the dynamometer.
2. Push the motorcycle onto the dynamometer.
3. Position the vehicle so that the driven wheels are ~2cm in front of the middle-point of the roller / dynamometer axis. Use integrated markers as reference.
4. Tie down the vehicle such that it won’t move back and forth or side-to-side during test run.
Please use fixing straps at front wheel support and at least one strap on each side of motorcycle.
Straps must be fixed to motorcycle frame or sub-frame or other component of sufficient stiffens.





Caution.
Accessory (non-OEM) foot pegs found on many race motorcycles ("track bikes") are usually designed for minimum weight thus their stiffness might be insufficient to withstand the loads / forces generated from suspension during dynamometer testing.

Warning!  Lethal hazard.
dynoKRAFT is strongly advising users to the test vehicles using chain or steel cable hoist (puller).
Do not use polyester lashing tie-down straps, routed near exhaust system, to fix test vehicle!
Serious risk of lethal injuries or loss of life!

ADAQbase installation. Basic software configuration

Please refer to the relevant operating instructions:
ADAQbase user manual
ADAQ Software user manual

Check routine before performing a test run

Before performing a test run or starting-up the engine please follow these steps to assure safe dynamometer operation:
- Check if the vehicle is properly secured on the dynamometer.
- Check if there are no visible leaks or fluid losses in the dynamometer or the motorcycle
- Check the overall technical condition of the vehicle to be tested (oil level, tire pressure etc)
- Check if there are not loose parts or tools left on the dynamometer or the vehicle
- Ensure that any personnel that is not performing the test is standing clear of dynamometer and the vehicle
- Ensure that the dynamometer and vehicle cooling as well as the exhaust gasses extraction system are operating correctly

Once you have performed these basic checks you should be clear to start up the engine.
These check routine should be performed before every test!

Before you will apply any load to the engine please warm it up. The engine oil temperature should be at least 70°C.

Warning! Lethal hazard.
Leaving any loose parts or tools on the dynamometer or vehicle may result in serious lethal hazard.

Special considerations for ABS, ESP,  TC, "City Safety" and Quick-shifter systems found in vehicles

Please deactivate all safety systems in the vehicle such as ABS, ESP, city safety or similar automatic braking systems or traction control before the test run.
After completing the test session and removing the vehicle from the test bench, please reactivate all previously deactivated systems.

Many modern vehicles are equipped with dual-clutch transmissions or so-called quick-shifter and/or auto-blipper systems which allow changing gears under load without using the clutch.
Usually these systems operate by cutting ignition which results in instant, temporary reduction of load in transmission, thus enabling the gear change.

Since the dynamometer controller calculates the engine RPM by measuring the roller RPM and multiplying it by total ratio changing the gear during a test run will result in incorrect calculated RPM value and may lead to unpredictable conditions.
This is especially true while performing “Manual” or “Power Sweep" tests where the eddy current brake is used to control the calculated engine RPM.

Changing gears with quick-shifter removes the load from the system (ignition cut). The ADAQbase dyno control system will react to these load changes instantly by reducing Eddy Current brake output to 0 and - once the ignition system is back on - applying excessive load to stabilize the sudden change in engine RPM.
The fact that during gear change also the ratio has changed will exaggerate the brake reaction even further.

As a result, the excessive load from eddy current brake may be so high, that the tie-down straps or foot-pegs may break! 

Warning! Lethal hazard.
DO NOT use quick-shifter or change gears while recording test runs.
During “Manal” or “Power Sweep" test do not perform any gear changes - especially using quick-shifter mechanism.

This will lead to unstable running conditions while recording an testrun and may result in total equipment damage as well as severe injury to operator or death.


Maintenance

Periodic maintenance by the dyno operator

All dynoKRAFT test stands have been developed with a minimum of maintenance to enable problem-free operation for years.
However, as with any high-performance equipment an basic, periodic maintenance is required to ensure problem-free operation.

Warning! Lethal hazard.
Before carrying out maintenance or repair work, always switch off the main power supply of the test bench and unplug the power cord.
Please follow the warnings listed in the "Warnings" chapter!
