pplication description EN Emergency-off application Manual motor starter MS116/MS132 Undervoltage release U1 The emergency-off application allows machine and job safety for nominal currents up to 32 all in one. It complies with EN60204-1 standard stop-category 0. It also complies with additional legal and standard requirements for electrical and functional safety of machinery. Introduction This publication gives an overview on functionality and on relevant standards for an emergency-off application according to category 0. It also explains how to select the necessary components to realize the application. The emergency-off for uncontrolled stopping in accordance with EN60204-1 (E-off, stop category 0) interrupts the motor current directly. The torque becomes zero and the motor coasts down. This application can be found in many industries such as: - packaging - food and beverage - plastics processing - steel and aluminium - timber industry - manufacturing industry Manual motor starters Manual motor starters (MMS) are protection devices for the main circuit. They combine motor control and protection in a single device. MMS are used mainly to switch motors manually ON/OFF and to protect them and the installation fuseless against shortcircuit, overload and phase failures. Fuseless protection with a manual motor starter saves costs and space and ensures a quick reaction under short-circuit condition, by switching off the motor within milliseconds. BB s manual motor starters can be equipped with many other accessories. To realize the emergency-off application the combination of a manual motor starter with an undervoltage release and an emergency stop device provides safety at work and machine safety all in one.
Manual motor starter MS116/132, undervoltage release U1 Benefits and scope The emergency-off application is useful for machinery and equipment preventing hazards for human life and machinery. It can be used for motors with nominal current up to 32 and maximum rated operating voltage up to 690 V C / 250 V DC. Electrical scope: Characteristic for this application is that after pushing the emergency-off device, voltage is not longer present and further danger excluded, e.g. Laboratory benches. Motor-operated scopes: Differently, in these cases the dangerous situation is still existing, even if voltage is no longer present after pushing the emergency-off. Typical applications include: - garage doors - mixing and kneading machines - carwash facilities - box column drills, lathes and milling machines - grinding machines - lifting devices - presses Motor-operated applications require an emergency-stop function according to IEC/EN 13850, and cannot be realized with the solution presented here. Function In case of a hazardous situation with a running engine, by pushing the emergency-off device, the MMS is tripping, which de-energizes the motor. The danger situation is averted. The signalling contacts may be used for visualization of a tripping. Standards Table 1 lists all fulfilled standards and relevant guidelines for the presented solution. The solution complies also with C TYPE 0 - system as described in ISO 13849 and IEC 62061, coming into effect in 2017.

Manual motor starter MS116/132, undervoltage release U1 Components Emergency-off applications in accordance with IEC-, IEN60204-1 stop category 0 using MS132 are designed for nominal currents up to 32. The components are designed according to the requirements and have to comply to international regulations and standards. Even under difficult environmental circumstances and operation conditions the components of this solution stay reliable for a long period of time. Since an emergency-off solution needs to stop the machine as quickly as possible without creating additional hazards, a risk analysis needs to be conducted in any case to ensure the correct connection. The manual motor starter (MMS) is extended by the undervoltage release U1. U1 and the emergency-off device E-off are electrically connected. When pressing E-off the MMS is tripped mechanically through the undervoltage release. ll parts are immediately de-energized and the motor stops. ccording to the standards E-off is red on yellow background, the emergency-off grab wire is red for high visibility.
