3 Basic technical principles Introduction What is meant by a "position detector" is any device which needs to be operated by a member which exerts a physical force, in view of : - either the form which its operating device takes - or the considerable force needed to operate it The distinguishing features of position detectors are : - their high electrical performance capability - their excellent resistance to accidental impact - good protection against splashed or dripping water -a wide range of operating devices to allow the detectors to be adapted to a vast variety of mechanisms Construction Our detectors are designed to conform to international IEC recommendations and/or European standards (EN). Proof that a detector conforms to these standards or recommendations takes the form of a conformity declaration made by the manufacturer (drafted as indicated in guidance document ISO/IEC - EN 450-4). Characteristics in line with the general requirements of standards NFC 6340, IEC and EN Leakage paths and air gaps : IEC NFC Our position detectors which comply with IEC can be fitted to machine-tools and industrial machines complying with NFC 7930, IEC 04., EN6004 or VDE 3. Electrical characteristics Assigned working current (Ie): - the current level adopted as a basis for the operating conditions quoted for a detector, and for the life tests on it. Thermal rating (Ith): - the current the microswitch will withstand when not being operated electrically, for a temperature rise of not more than 60 C. Assigned insulation voltage (Ui): - the voltage adopted as a reference for the dielectric tests and leakage paths. It must be equal to or greater than the assigned working voltage. Categories of use (IEC ): - AC 5 for operating AC solenoids and electromagnets - DC 3 for operating DC solenoids and electromagnets Contact element designation (IEC ): -a letter and number which define the use category and the assigned working voltage and current For example, A 300 means : in category AC 5, a maximum working voltage of 300 V and 6 A at 0 V or 3 A at 40 V. Contact block electrical wiring diagram Form Za Form Zb Rules and regulations EC Directives Our detectors conform to the EC Low Voltage Technical Directive 73/3/EEC and can be used in accordance with the specifications of the Machinery Directive 89/39/EEC. Environmental conditions Temperature limits When they are used in the temperature range quoted, the mechanical and electrical characteristics of our position detectors will remain substantially unchanged. If you intend to use them outside this range, please consult us. Protective treatment The treatment given to our position detectors is suitable in the vast majority of applications. Parts made of steel are zinc-coated or painted according to their mechanical function. Further information is available on request. This treatment allows our detectors to be used under the following temperature and humidity conditions : T C Relative humidity % This treatment may thus be suitable for applications in tropical or equatorial climates where the equipment concerned is in an interior location sheltered from direct exposure to atmospheric conditions. Other types of reinforced protection are possible for resistance to very severe environments. Please enquire. Mounting requirements Electric shock protection. The user should observe the mounting instructions relating to the mode of protection against electric shocks defined in the IEC 536., EN NFC 0030 standards : Class I : earth circuit link. Protection via differential circuit-breaker. Class II : double insulation. Class III : very low safety voltage. Screw tightening torque : : Actuator tightening. to.5 Nm Plastic Metal body body : Head fixing screw 0.7 to 0.8 Nm 0.8 to Nm 3 : Body fixing screw 0.7 to 0.8 Nm 0.8 to Nm 4 : Fixing screw to.5 Nm Adjustment of rotary heads with momentary action to right and left : For series , 83 85, 83 86, , , (x 360 ) 4 3 Both contacts have the same polarity The contacts are electrically isolated Positive break contact operation (IEC , chapter 3) For contacts used in safety applications, limit switches, emergency stop devices, assurance that opening has occurred is essential (see IEC 04, EN6004). After each attempt, contact opening is checked by an impulse voltage test (500 V). Contact element : - Snap action contact This is characterized by tripping points and release points which cannot be confused. The speed at which the control devices moves is independent from the speed of the control device. This feature makes it possible to obtain satisfactory electrical performance even where the control device is moving at low speed. A: Total travel (TT) of the control device A B : Pre-travel (PT) until the contact element B F opens C : Release travel until the contact element closes 0 D : B-C = Differential travel C D F : Travel required to reach the positive opening point (POT) Degree of protection Under the IEC 59 or NFC 000 classification scheme, standards employ an IP code to define the degree or class of protection which a position detector provides against access to live components and against the entry of solid foreign bodies and the entry of water. st numeral Protection equipment provides against the entry of solid foreign bodies 0 (not protected) 4 diameter mm 5 protected against dust 6 sealed against dust nd numeral 0 (not protected) 4 splashed water 5 hosed water Protection for persons against access to dangerous parts (not protected) mm Ø wire mm Ø wire mm Ø wire Protection equipment provides against the entry of water 6 high-pressure hosed water 7 temporary immersion 8 prolonged immersion /

29 OPEN Basic technical principles Standards Extract from standards EN 9- and EN 088. Moving guards to prevent risks created by moving (and therefore dangerous) parts must be used in conjunction with locking devices or interlocks with guard locking. Interlocks with guard locking must be used on machines with inertia. An interlock with guard locking must be used if the stopping time is greater than the time required for a person to reach the danger zone. This mechanism will delay unlocking the moving guard until the dangerous movement has actually stopped. Areas of application Key-operated safety interlock switches have been designed specifically for protecting operators working on dangerous machines. They can be used to lock or unlock moving guards on industrial machines, and meet the requirements of standards EN 9-, EN 94, EN 088 and EN Key-operated safety interlock switches are mainly used in applications which form part of the machine operating process. They are used to stop any dangerous movement whenever the moving guard system is open. Examples of application Monitoring of immediate access moving guards NO NC Machine control circuits The use of safety interlock switches in conjunction with XS and RS safety relays creates control circuits conforming to EN Operating principle The start circuit is only closed after the key has been inserted fully and is used to close the NC contacts. Removing the key once the moving cover is open causes the positive action opening of the NC contact(s). The opening of the moving guard can be: Immediate Machines without inertia. Machines with a stopping time which is less than the time taken to access the danger zone. Delayed Machines with a stopping time which is greater than the time taken to access the danger zone.

30 Key-operated safety interlock switch, plastic Without key locking: Switches with plastic body for use on light machinery, without inertia. For use in unstable environments where there is a risk of the guard opening accidentally (due to vibrations, if the guard is positioned at an angle, bouncing of the guard, etc). The guard is kept closed by adding a door stopping mechanism. With interlocking and locking of the key using an electromagnet: Devices in plastic cases for use on machines with inertia, or which require controlled opening of the guard. The moving guard is locked by removing the voltage, or by applying voltage to the electromagnet. A special tool can be used to unlock the guard manually, to ensure the safety of personnel carrying out maintenance operations on the machine, or if there is a malfunction. Key-operated safety interlock switch, metal Without key locking: Switches with metal body for use on machines without inertia in a stable environment where there is no risk of the guard opening accidentally (due to vibrations, if the guard is positioned at an angle, bouncing of the guard, etc) With interlocking and locking of the key using an electromagnet: Devices in metal cases for use on machines without inertia, or which require controlled opening of the guard. The moving guard is locked by removing the voltage. A key-operated lock can be used to unlock the guard manually, to ensure the safety of personnel carrying out maintenance operations on the machine, or if there is a malfunction. These devices are fitted with LEDs: one indicates the opening/closing of the guard, the other whether it is locked. Safety switch for hinged guards With angular or rotary movement head: Switches with plastic body and angled lever or rotary shaft. For use on small industrial machines with compact doors, covers or rotating housings. The devices ensure the safety of the operator by stopping dangerous movement immediately when the lever or rotary shaft reaches an angle of 5. The devices provide a solution for monitoring rotary guards with a small opening radius on machines without inertia. They are particularly suitable for adapting existing machines to meet applicable standards, as they can be mounted on covers which are already installed, including those mounted imprecisely. Mounting the switch increases the safety of the operator as it reduces the opening distance of the guard, and therefore the risk of reaching the danger zone. /3

34 Locking / unlocking using an electromagnet Type safety switches are fitted with an electromagnet for locking/unlocking the guard. With the guard locked, the force required to remove the key is 50 dan. In addition to the -pole contact element actuated by the key, type limit switches also have a positive break type NC contact element, actuated by the electromagnet. The NC contact is integrated in the machine safety circuit. Unlocking using a special tool UNLOCK Type safety switches are supplied with a tool () which can be used to unlock the moving guard, bypassing the electromagnet. Unlocking using a tool is recommended in the following cases: machine maintenance (if the tool is in the UNLOCK position and then removed, this will prevent the machine from restarting accidentally, therefore ensuring the safety of maintenance personnel), mains failure, problem with unlocking (locking cannot be released: fail-safe condition). Unlocking by applying voltage to the electromagnet always takes priority over unlocking using a tool. The NC contact is integrated in the machine safety circuit. Power supply for the electromagnet on The electromagnet for type safety switches is supplied by an electronic circuit which increases its service life. As the 4 V version is protected by a bridge rectifier, an A.C. or D.C. supply can be used. Dimensions The 0 V and 30 V versions are A.C. only. It is also protected against voltage surges.

38 Locking / unlocking using an electromagnet Type safety switches are fitted with an electromagnet for locking/unlocking the guard. With the guard locked, the force required to remove the key is 00 dan. In addition to the 3-pole contact element actuated by the key, limit switches also have a positive break type NC + NO contact element, actuated by the electromagnet. The NC contact is integrated in the machine safety circuit, and the NO contact indicates the position of the electromagnet. Locking using a key on LOCK UNLOCK Power supply for the electromagnet on The electromagnet for type safety switches runs on D.C. and is therefore particularly reliable. Connections Category according to EN 954- Examples of wiring diagrams with a fuse to provide protection against short-circuits in the cable or tampering. Locking by removal of voltage NC+NO+NO Type safety switches are supplied with a key-operated lock which can be used to unlock the moving guard, bypassing the electromagnet. Unlocking using a key-operated lock is recommended in the following cases : machine maintenance (if the key is turned to UNLOCK and then removed, this will prevent the machine from restarting accidentally, therefore ensuring the safety of maintenance personnel), mains failure, problem with unlocking (locking cannot be released: fail-safe condition). Unlocking by applying voltage to the electromagnet always takes priority over unlocking using a key-operated lock. The locking mechanism for standard devices allows the key to be removed in the LOCK and UNLOCK positions. As it is protected by a bridge rectifier, A.C or D.C supplies can be used (4 V, 48 V, 0 V or 30 V). It is also protected against voltage surges.

44 Presentation and foot switches are an ideal solution for controlling starting and stopping of numerous industrial machines with many different operating modes: pulsed, step-by-step, continuous. The range comprises metal foot switches (for heavy loads where there is an increased risk) for heavy duty requirements, and plastic foot switches (for lighter loads where there is a reduced risk). Terminology Positive break operation A device meets the requirements of this specification when all its normally closed contact elements can be safely set to their opening position. All foot switches fitted with a snap action NC+NO contact element are positive break type and meet all the requirements of standard IEC , section 3. Snap action contact The linear speed of the moving contacts is independent of the speed of the control device. This feature enables high levels of electrical performance, even with low control device linear speeds. Safety contacts Fitted with a protective cover, metal foot switch should be used whenever a start/stop command could pose a danger (increased risk) foot switches without covers are suitable for start commands which pose a reduced risk and for machine stop commands. Devices with snap action positive break type contacts. Metal foot switches can have one or two NC + NO contact blocks. These foot switches are in positive operation when released: positive actuation is required to maintain the machine in rest mode or cause it to stop (machine stop). -step pedals Pedals with two steps are ideal for machines with two operating speeds. Examples: - first speed: slow (used for tool adjustment or maintenance), - second speed: fast (used for normal machine operation). The first step, connected to an NC + NO contact, is achieved by briefly applying gentle pressure to the foot switch (6 mm and dan depression). 6 mm st step The second step, connected to a second NC + NO contact, is achieved by applying maximum pressure to the foot switch ( mm and 9 dan for depression up to the end stop). mm nd step Dimensions mm with protective cover threaded holes for cable entry maximum capacity 4 mm untapped hole for cable entry maximum capacity mm untapped hole for cable entry maximum capacity 8 mm Other information /7
