USER MANUAL

INTRODUCTION

Thank you for choosing the product by ТМ MSG equipment.
The actual User Manual contains information on application, technical characteristics, package contents, design of MS1000+ and all the important details regarding its operation.
It is strongly recommended to learn carefully the actual User Manual before putting MS1000+ (hereinafter, “the test bench”) in operation, take special training at the equipment manufacturing facility if necessary.
Due to the continual improvement of the test bench structure and configuration as well as firmware upgrade, some changes might not be reflected in this User Manual. The test bench firmware will require update. Later, firmware support and maintenance can be discontinued without prior notice to users.
WARNING! The actual user manual does not contain information on how to diagnose shock absorbers with the test bench. Follow the link MS1000+ MANUAL FOR DIAGNOSING SHOCK ABSORBERS to find this information.

PURPOSE

The test bench is designed to assess technical condition of shock absorbers in passenger cars through taking their force-displacement and force-velocity characteristics.
The test bench for shock absorbers is used to do the following:

• establish whether a faulty unit should be repaired or replaced;
• check on the quality of repair;
• assess the conformity of shock absorber performance to its technical specifications;
• conduct prolonged tests.

A shock absorber can be tested on the test bench both in manual and automatic modes.
The test bench functionality enables the following:

• test all types of passenger car shock absorbers having dumping force up to 1000 kg and equipped with different mounting mechanisms;
• save test-results;
• compare test results with reference data (before and after repair);
• generate test reports and print them on an external printer.

APPROPRIATE USE

1. The bench is used only for its intended purpose (see sect. 1).
2. In the test area, it is prohibited to carry out any repair work on the shock absorber. This may lead to the breakdown of the bench.
3. The shock absorber mounts securely in the pneumatic clamp. Do not allow any backlash between the shock absorber and pneumatic clamps. This will result in unreliable diagnostic data and a breakdown of the bench.
4. It is prohibited to test a knowingly defective shock absorber and shock absorber with a spring.
5. The bench shutdown should be performed through the interface of the service program, by clicking on the «Turn off the bench». After the monitor goes out, you can turn the «ON/OFF» button into the «OFF» position.
6. Use the button «EMERGENCY STOP» only if necessary to stop the diagnostic process in an emergency.
7. The touch screen saving uses the stylus (supplied as a set).
8. The bench operating is prohibited in a defective condition and not connected to the ground.
9. To avoid damage or failure of the bench, it is not allowed to make changes to the bench at one’s discretion. The bench cannot change by anyone other than the official manufacturer.
10. Computer equipment and software use not designed to work with this bench voids warranty obligations (even if the software and equipment were subsequently deleted). Only the original MSG equipment software can be installed on this hardware.
11. In the case of a breakdown in the operation of the bench, it should be stopped further and contact the manufacturer or the sales representative.

5.1. Safety regulations

1. Only trained and authorized personnel is qualified to operate certain test bench types.
2. It is strictly prohibited to activate the test bench when the doors of mechanical and electrical units are open. DO NOT open the doors before the expiry of 10 minutes after power off.
3. Avoid dropping a shock absorber during its mounting/dismounting on the test bench.
4. Keep your work space clean, well-illuminated, and spacious.
5. Before testing, make sure the test bench is earthed and in good order. Otherwise the operation of the test bench is strictly forbidden.
6. Disconnect the test bench from the power supply before starting any maintenance work.

5.2. Test bench mounting and setup
The test bench is delivered in packaging. Unpack the test bench and make sure it has no damages. Packaging materials are fully recyclable and should be wasted separately from domestic garbage. Position the test bench upright (use a leveling gauge) on the level floor. When moving the test bench, do not hold it by its movable or perforated parts. Put vibration-absorbing pads under the test bench legs.
Keep the distance of at least 0.5 meters between the test bench and the room walls or any other objects. The test bench ensures safe operation in the temperature range between +10 °С and +40 °С and relative humidity of 10-90% (without water condensation).
Before launching the test bench, connect it as follows:
– to 400V power supply line;
– to compressed air source.

TEST BENCH MAINTENANCE

Test bench is intended for long-lasting operation under twenty-four-hour schedule. However, for trouble-free enduring operation it is essential to inspect the test bench and observe preventive measures described below with recommended intervals. Inspection and preventive measures should be carried out by a qualified specialist.
Special attention should be paid to the following aspects of daily inspection:

• Appropriate operation of the motor (no unusual sounds, vibration, etc.).
• Appropriate ambient conditions for the test bench use (temperature, humidity, air pollution, vibration, etc.)
• Correspondence of supply voltage range to the test bench operation requirements. Weekly inspection of the test bench must include the following:
• Visual inspection of the bearing unit and puller shaft for traces of oil leaks.
• Check the moving parts of the upper and lower pneumatic clamps for sufficient lubrication.

WARNING! Improper fixing of shock absorbers in pneumatic clamps is the most common cause of the test bench malfunction.
6.1. Pneumatic clamps oiling
Once a month check the lubrication of wear surfaces of linear cams (n.1, Fig. 6, 7) and glide slide blocks (n.2, Fig. 6, 7). Litol-24 is a commonly used grease. Other lithium-based greases are also usable.
Remove visible residue of old grease with a waste cloth before oiling pneumatic clamps. Move the clamps several times.
6.2. Bearing unit oiling
As the lubricating grease picks up dirt and loses its qualities with time, it should be refreshed every once in a while. The intervals at which the lubrication should be replaced or refreshed depend on the severity of use. However, the maximum interval shouldn’t exceed two years. During the first two times, lubrication can be refreshed. Subsequently, it must be replaced. Litol-24 is a commonly used lubricant. Other lithium-based greases are also usable.
To replenish the lubricating oil, use the nipple on the bearing unit (Fig.13) and a special syringe.

Figure 13. Nipple on the bearing unit
Follow the instruction below to oil the bearing unit:

1. Disconnect the test bench form a supply line and wait for 10 minutes.
2. Open the door of the mechanical unit.
3. Remove the cap from the nipple, having it and the adjoining surfaces previously cleaned from dirt and dust.
4. Use a special syringe to inject grease into the nipple. Continue to pump until you see grease squeezing out from the bearing.
5. Upon finishing, remove the remaining grease with a cleaning cloth.

6.3. Puller shaft oiling
The lubricant type as well as grease replenishment and changing schedule are similar to the ones used for bearing unit maintenance (Section 6.1).
Follow the instruction below to oil the puller shaft:

1. Disconnect the test bench form a supply line and wait for 10 minutes.
2. Open the door of the mechanical unit.
3. Clean the grease nipples (Fig.14) and adjoining surfaces from dust and dirt.
4. Screw off one of the grease nipples.
5. Use a special syringe to inject grease into the nipple. Continue to pump until you see grease squeezing out from the bearing.
6. Upon finishing, remove the remaining grease with a cleaning cloth. Screw in the grease nipple

Figure14. Grease nipples on the puller shaft.
6.4 Gear motor inspection and maintenance
Perform the following maintenance procedures:
Every 500 hours of work or every month:

1. Inspect the gear motor visually for possible oil leakage.
2. Remove dust with a vacuum cleaner – the layer of dust accumulated on the gear motor cannot exceed 5mm thick.
   Every 5 years:
   Replace synthetic oil.

6.5 Cleaning and care
Use soft tissues or waste cloth to clean the test bench surfaces. Clean the touch screen with a special fibrous tissue and spray for display screens. Do not use any abrasive materials or solvents to avoid damage to the screen or corrosion.
