ICM/ICAD Motorized Valve

Installation, Programming, and Troubleshooting

 

 

Common Questions

What happens in the event of a power failure?

The ICAD will remain in the position it is in when power is lost. There are two ways to address this condition:

Add a UPS (Uninterruptible Power Supply) to the power wiring. This is easily accomplished with the green and white wires in the power cable. A UPS is available from Danfoss. The UPS can provide service for up to 9 ICAD 600’s or up to 6 ICAD 900’s.

Note: The UPS is not a continuous power supply. It is used to change the valve position (usually to close the valve) in the event of a power failure. Therefore, the system is not to be run in the UPS mode.

Add a solenoid valve in front of the ICM. This is a very simple solution provided that there is no issue associated with the additional pressure drop through the solenoid valve.

How much power do I need to supply to the ICAD?

The total power required depends on both the ICAD size and the number of ICAD’s powered by the DC power supply. The power for each ICAD is:

For the ICAD 600 (used on ICM 20, 25, and 32), the power requirement is approximately 30 W

For the ICAD 900 (used on ICM 40, 50, and 65), the power requirement is approximately 50 W

How can I monitor the valve position remotely?

The control wiring provides for a 4 to 20 mA or 0 to 20 mA signal output (blue and yellow wires). This signal can be sent to:

A remote display

A PLC or PC

Another ICAD motor to give the same opening position

VSS, VSM, VSR specifications

Emerson VSM, VSR, and VSS are advanced technologies designed for process automation and control, often utilized in industrial applications. These systems are part of Emerson's broader portfolio of solutions aimed at enhancing operational efficiency, safety, and reliability.

The Emerson VSM, or Valve Signature Management, focuses on the digital management of valves within a system. One of its main features includes advanced diagnostics that monitor the health and performance of control valves. This technology allows for predictive maintenance, ensuring that valves operate at peak efficiency and reducing the risk of unexpected failures. The VSM utilizes a combination of smart sensors and actuators to gather data, enabling real-time analytics that can enhance decision-making and operational strategies.

On the other hand, VSR, or Valve Status Reporting, enhances visibility into the operational state of valves in real time. This system provides operators with critical updates and alerts related to valve conditions, significantly reducing response times to potential issues. The VSR technology integrates seamlessly with existing control systems, allowing for easier implementation and minimal disruption to ongoing operations. The reporting capabilities feature user-friendly dashboards that present complex data in a straightforward manner, empowering operators to make informed decisions quickly.

The Emerson VSS, or Valve Service Solutions, complements the VSM and VSR by focusing on the maintenance and support of valve systems. This offering includes comprehensive service packages that range from routine maintenance to advanced troubleshooting and repair. The VSS is designed to improve the lifespan of valves through proactive service, ensuring reliability and minimal downtime. Emerson’s trained technicians leverage predictive analytics derived from VSM and VSR data, allowing for timely intervention before issues escalate.

In summary, Emerson’s VSM, VSR, and VSS technologies work together to create a robust ecosystem for valve management in industrial settings. The combination of advanced diagnostics, real-time reporting, and comprehensive service solutions provides operators with a powerful toolkit aimed at optimizing performance and ensuring operational reliability. With these technologies, companies can embrace digital transformation, reduce operational risks, and improve overall process efficiency, leading to a safer and more productive environment. Each component plays a crucial role in empowering industries to meet the challenges of modern automation and maintain competitive advantages in their respective markets.
