System Diagnostics to Detect Operational Abnormalities

Detection of ground trouble and soft ground

1.For a case of unstable ground or soft ground (soil containing high clay content) for which the use of this machine is not suitable, only the green and red LEDs will be on (Figure 24), with no yellow LED's on.

If this occurs it would be challenging to achieve the desired compaction results. Check to make sure the ground conditions are prepared to specification before proceeding with the compaction process.

2.When appropriate vibration frequency cannot be achieved during operation due to improper engine RPMs (Figure 25) the green LED will flash. When this occurs check the engine RPMs and the V-belt tension as it could be loose.

Multiquip MVH406DSZ System Diagnostics to Detect Operational Abnormalities, Function to Detect Electric System Abnormality

MVH406DSCPAS, MVH406DSZ specifications

The Multiquip MVH406DSZ and MVH406DSCPAS are powerful and robust vibratory plate compactors designed for various construction and civil engineering applications. These machines are engineered to provide exceptional performance, durability, and ease of use, making them suitable for both professional contractors and DIY enthusiasts.

The MVH406DSZ model features a reliable air-cooled, four-stroke gasoline engine, delivering optimal power and efficiency. With a weight of approximately 400 pounds, it offers excellent stability while compacting soil and asphalt materials. The machine operates at a frequency of around 5,600 vibrations per minute (VPM), ensuring rapid and effective compaction across various surfaces. The heavy-duty base plate measures 24 inches in width, providing optimal coverage for large areas and enhancing productivity on the job site.

One of the standout features of the MVH406DSZ is its innovative anti-vibration technology, designed to minimize operator fatigue during extended use. This feature allows for a more comfortable operating experience, as the vibration levels are significantly reduced, enabling operators to work longer without discomfort. Moreover, the ergonomic handle is adjustable and designed for ease of maneuverability, ensuring that operators can guide the compactor effortlessly around obstacles.

On the other hand, the MVH406DSCPAS model features similar core specifications but comes equipped with additional benefits, such as the compactor’s ability to use multiple attachments for various tasks. This versatility is a key characteristic that makes the MVH406DSCPAS model particularly advantageous for contractors looking to maximize their equipment's utility on diverse jobs.

Both models are designed with durability in mind, featuring high-quality materials that can withstand the rigors of frequent use. The plates are constructed from heavy-duty steel, ensuring longevity and resistance to wear and tear. Additionally, the compactors’ easy-access maintenance points facilitate quick oil changes and routine upkeep, prolonging the equipment's life and ensuring reliable performance.

In conclusion, the Multiquip MVH406DSZ and MVH406DSCPAS compactors are exceptional choices for anyone in need of reliable and efficient compaction equipment. With their powerful engines, advanced vibration-reducing technology, and rugged design, these models are well-suited for effective operation in both small and large-scale projects. Whether you require a machine for grading, trenching, or asphalt work, the MVH406 series delivers performance and durability that you can count on.
