3 Why do you need an Emergency stop? So that anyone shall be able to stop a machine during a machine break-down or if someone is in danger. How do I recognise an E-stop? E-stop buttons shall according to relevant standards be red with a yellow background. n emergency stop grab wire shall be red for high visibility. sign that indicates the location of the E-stop shall be green with a white picture and possibly with text in the local country's language. How shall an E-stop stop the machine? n E-stop shall stop the machine as quickly as possible. To obtain a quick stop one either removes the power directly or one lets a frequency converter 'run down' and afterwards after a little delay, remove the power. n E-stop shall not create other hazards. Therefore a risk analysis must be made for the E-stop to be correctly connected. From 00//EC, clause This device must: - have clearly identifiable, clearly visible and quickly accessible control devices, - stop the hazardous process as quickly as possible, without creating additional risks, - where necessary, trigger or permit the triggering of certain safeguard movements.... Requirements for E-stops are stated in the following standards and regulations 00//EC The Machinery Directive Clause... in nnex gives requirements for the emergency stop function for new machines). See also clause.. Control devices. (see chapter Standard and Regulations ) Council Directive 89//EEC (with amendments) concerning the minimum safety and health requirements for the use of work equipment by workers at work Clause. gives the requirements for the emergency stop function for older machines. See also clause.. (see chapter Standard and Regulations ) EN ISO 80 Safety of machinery Emergency stop Principles for design harmonized standard that gives technical specifications for the requirements in the Machinery Directive. Could also be used for older machinery. EN 00- Safety of Machinery - Electrical equipment of machines Part : General requirements.

7 Emergency stop with indication Smile pprovals; CERTIFIED BY pplication: To stop a machine or a process Features: Smile - small and cost effective E-stop Emergency push button up to cat. /PL e acc. to EN ISO 89- With LED info in push button Robust Push button IP, housing IP7 vailable as safety stop (black push button) vailable for S-i In order to fulfil the need for a small and easy to install E-stop, Smile has been developed. The size of the device makes it possible to be installed wherever you want. With M connection/s or cable and centralised mounting holes Smile is very easy to install, especially on aluminium extrusions. Smile is available for E-stops in both dynamic and static safety circuits i.e. for interfacing to Vital/ and Safety relays. Each version is available with either one or two M connections or cable. t the top of Smile, a LED shows the current status as: green = protection OK, red = this emergency stop has been pressed and if the LED is off, an emergency stop earlier in the loop has been actuated. Smile is also available with black push button and is used as a safety stop. See section on safety stops. Smile emergency stop has six different variants:. Smile 0E has a m cable connected through the base of the unit.. Smile 0EK has four m short connecting leads through the base of the unit. No LED.. Smile E has a five-pole M connector on one end of the unit. lso available with S-i.. Smile E has two five-pole M connectors, one on each end of the unit.. Smile ER has one -pole M connector at one end.. Smile ER has two -pole M connectors at each end. Smile E adapted for S-i The Smile E also comes in a version adapted for direct attachment to the S-i bus. :

With M connections or cable and centralised mounting holes Smile is very easy to install, especially on aluminium extrusions. Smile is available for E-stops in both dynamic and static safety circuits i.e. for interfacing to Vital system/ safety PLC and Safety relays. Each version is available with either one or two M connections or cable. Two M connectors are used to enable the connection of E-stops in series, which is often used with dynamic safety circuits fulfilling safety category. In the top of the Smile Tina E-stop unit, LEDs show the actual status according to the dynamic system: Green = everything is OK, Red = E-stop activated. Flashing Red/Green = Stop activated from another preceding device. Smile is also available with black push button and used as a safety stop. See section on safety stops. The Smile Tina emergency stop is available in four versions:. Smile 0E Tina has a m cable connected via the base of the unit.. Smile E Tina has a five-pole M connector on the end of the unit for connecting the Jokab Safety cable.. Smile E Tina has two five-pole M connectors, one on each end of the unit for connecting the Jokab Safety cable..

15 Emergency stop with indication Smile S-i pprovals: CERTIFIED BY pplication: To stop a machine or a process Safe input node in S-i systems Features: Smile E S-i is an emergency stop with a built-in dual channel safe S-i input node. The S-i bus and the safety around it is specified by the two organisations S-International ssociation and S-Interface Safety at Work, and is described in publications such as S-Interface The utomatic Solution. Smile E S-i is supplied with 0 V DC from the S-i bus. The recommended connection to the S-i bus is made via a flat cable terminal to M (see Figure), which makes it possible to quickly and easily connect the device to the yellow S-i cable. Smile S-i can also be connected directly to the S-i bus using only two conductors (pins and on the unit's M contact). Smile is also available with black push button and is used in this case as a safety stop. See section on safety stops.

17 Safety stop Inca and Smile When should I use the safety stop? Safety stops are used to stop the operation of a machine in a safe manner. It must not be used as an emergency stop, but only as a stop for an individual hazardous motion. This is indicated by black push button. Likewise, an emergency stop push button with red push button must not be used as a safety stop. Inca for panel mounting The Inca series is available with black push button and is called Inca S/Inca S Tina. The safety stop is identical to the corresponding emergency stop apart from the black push button. For technical data see the Inca emergency stop. Smile with indication The Smile series is available with black push button and has a similar designation apart from an S in the name instead of E. The safety stops are identical to the corresponding emergency stops apart from the black push button.
