Festo MS6-E2M energy-efficiency module

The MS6-E2M energy-efficiency module can actively intervene in the air supply, particularly during standby operation, reducing the consumption of compressed air. At the same time, the automatic monitoring of important operating parameters such as flow and pressure ensures a reliable production process. The module is suitable for new energy-efficient machines and, with the simple connection of the sensors to a PLC, it can also be used as an easy retrofit on older installations which need to operate more energy efficiently.

The energy-efficiency module can be adapted by the user by means of a manual input device (MMI) or Profibus to the requirements of a particular installation. The user can quickly and easily specify parameters on the basis of which the E2M detects whether the machine in question is currently in production operation or not. During downtime the compressed air supply to the machine is shut off, thus preventing any air from escaping through leakages in the machine. This works in a similar way to the automatic stop/start system in a modern car so that no more energy is wasted.

When the product is in shut-off mode, it checks the installation for leaks. If the energy-efficiency module detects a pressure drop equal to a value predefined by the user, it signals this to the plant control system. The E2M automatically detects leaks in a piping system, enabling the user to carry out maintenance as and when needed.
