4 General According to EN 88, interlocking devices are mechanical or electrical devices which are designed to prevent the operation of a machine element for as long as the movable safety guard is left open. Safety switches without a guard locking device are used if the control concept is structured in such a way as to ensure that:! the machine shuts down immediately upon opening the safety guard or! the stop time (the time between the stop order being triggered by the interlocking device and the point of no further risk from hazardous machine function) is shorter than the access time. In the case of these safety switches, there are a number of different operating principles:! Mechanical safety switches, e.g. EUCHNER series N, NP and NM safety switches Compared with electromechanical safety switches, they are used if:! a machine needs to be made extremely tamper-proof! extremely hygienic environmental conditions are required (e.g. in the food industry)! poorly aligned guarding is a problem! machine doors are subjected to strong vibrations! a high safety category is determine on the basis of the risk analysis EUCHNER s CMS safety switches are based on the magnetic principle. The tamper-proof coded system was specifically developed to monitor moving machine components and movable safety guards.! Non-Contact Safety Switches based on transponder technology, e.g. EUCHNER CES series safety switches! Non-Contact Safety Switches based on a magnetically coded principle, e.g. EUCHNER CMS series safety switches Non-Contact Safety Switches are interlocking devices which are designed to protect people and machines.

6 Functional description Coded Magnetic Safety switches CMS consist of three components:! Actuator! Read head! Evaluation unit Coded actuators are an arrangement of several permanent magnets within a housing. The number of magnets, their position (polarization) and magnetic field strength in the housing are characteristics of the different actuators. Within a series, the individual actuator coding is identical. Using identical coded actuators allows for quick and easy installation and replacement. Reed contacts are fitted in the read head of the CMS safety switch. The operating principle for the reed contacts (NC contacts or NO contacts), the number of reed contacts fitted and their physical arrangement determine the type of read head. When the actuator is correctly oriented to the read head, the contact blades of the read head will close when under the influence of the magnetic field of the actuator. The actuators and read heads are matched in pairs are available in 4 different housings. Depending on the application, the system operator can select cube-shaped or cylindrical design. The read head only responds to the specific mating actuator type. The appropriate read head must be matched to the evaluation unit (see evaluation unit s technical data). A fault could be caused by a short circuit in the connecting lead or by welding of a reed contact in the closed position. If a reed contact is welded, the magnetic force might not be strong enough to open the contact. For reasons of safety, several reed contacts (2 or 3, depending on the switch type) are fitted to each read head. The NC contact/no contact combination is mentioned by way of example. If the actuator is moved to the read head s response area, the reed contacts are switched by the magnets (the actuators). Magnets with different polarization are assigned to the NC or NO contact. The downstream evaluation unit monitors the read head in that the NC/NO contacts in the read head must always have opposite states. If this is not the case, the safety outputs of the evaluation units are not switched and the unit switches to the blocked state. The read head is fixed to the fixed safety guard component and is connected to the evaluation unit via a two or four wire cable. When the safety guard is closed, the actuator is moved up to the read head. As soon as the actuator is in the response area (i.e., switch-on distance on is reached), the reed contacts in the read head switch on, i.e. they switch to their contact position. If the evaluation unit detects that the reed contacts are in position for all connected read heads, i.e. all actuators are in the response area, the safety output is closed. If the actuator is moved away from the read head, the magnetic field around the reed contacts is reduced as a function of the distance. When switching distance s off is reached, the reed contacts return to their pre-loaded position (home position). They switch over to the non-actuated state. The evaluation unit is the system unit which is downstream from the read head. Via internal relays, it switches the safety circuit as a function of the position of the reed contacts. The evaluation unit in degree of protection IP is mounted in the control cabinet. EUCHNER offers various evaluation units. The unit is selected on the basis of the number of read heads to be connected and the overall system safety category to be achieved. The relevant evaluation units are described in detail in the following chapters. In order to achieve a particular safety level, fault analysis must be carried out where safety-related components are used. 6

7 The sensitivity of the reed contacts and the field strength of the magnets determine the switching distance between the actuator and the read head. Diagrams of the typical response areas of the individual sensor units are shown for the technical data for the actuators and read heads. The record of the response area in s x, y and z provide the user with information regarding how the actuator and read head should be positioned. When ideally positioned, the read head is in the middle of the response area. Oblong slots are provided to facilitate actuator and read head adjustment. The table of combination options (see pages 8 and ) shows that the actuator and read head sensor units have a large response area. The advantage of this is that the door clearance setting may vary within the limits of the response area. The CMS safety switches have switching characteristics with hysteresis (s off > s on ). If the read head is barely adjusted in the actuator s s on response area, the plant will not be switched off immediately if the door vibrates slightly. The switch-on and switch-off distances shown in the table refer to the approach of the sensor unit in the x (frontal approach ). If the actuator approaches the read head from the side, the switching distances are likely to be reduced. The magnetic switches are notable for their high degree of protection and compact design. They are therefore particularly suitable for areas where dirt and cleaning are major factors. A major advantage of EUCHNER s CMS safety switch is that the actuator and read head can be fitted behind stainless steel. The switching distances are reduced in line with the material and wall thickness. This property facilitates the use of the switch in the food industry in particular. Installation using the rust-resistant safety screws (supplied) provides a tamper-proof mounting of the actuator and read head. 7

8 Non-contact safety switch CMS-E-AR! 2 read heads connectable (NO contacts wired in parallel, safety category 3)! Up to read heads connectable (NO contacts wired in series, safety category 2) Functional description The CMS-E-AR evaluation unit is used to monitor safety category 2 or 3 safety guards in accordance with IEC/EN Up to read heads can be connected in series to the CMS-E-AR evaluation unit. If the actuator is in the response area, the reed contacts in the read head are switched by the magnetic field and the NO contacts are closed. The CMS-E-AR evaluation unit processes the read head s NO contact signals. Each of these three inputs is connected to coils of independentaction relays in the evaluation unit. The electrically separated relay contacts are switched in series so that if the actuators are located in the read heads response area, the safety circuit (terminal 13/ 14) is closed. If the read head is located in the actuator s response area, this is shown by the two evaluation unit LED s (see table of LED displays). This display is particularly useful for starting up the plant and if servicing is required. When a safety guard is being monitored, a read head with reed contacts which are wired in parallel must be used (see wiring example 1, page 11). For the second unused connection area a four-pole bridge (supplied with the evaluation unit) should be connected. If a bridge has been fitted the relevant LED lights up and stays on. If the relevant actuator is moved to the read head s response area, the two LED s are lit and safety output 13/14 is switched through. If two safety guards are being monitored, read heads with reed contacts which are wired in parallel must also be used (see wiring example 2, page 11). If three or more read heads are connected, the area most frequently accessed must be monitored by a read head with reed contacts wired in parallel. Any additional read heads with internal reed contacts which have been wired in parallel must be connected in series (see wiring example 3, page 11). The three-pole bridge supplied with the unit must be used for any unused terminals.

22 Non-contact safety switch CMS-E-BR! 4 head inputs connectable (safety category 3)! 1 door monitoring output! 1 feedback circuit connectable Functional description The CMS-E-BR evaluation unit is used for monitoring one to four guards in safety category 3 in accordance with IEC/EN The relevant read heads for the evaluation unit have electrically separated reed contacts each of which has one NC contact and one NO contact (see wiring examples on page 23). If the actuator is in the response area, the reed contacts in the read head are switched by the magnetic field. The switching status of the reed contact is displayed on the evaluation unit's LEDs (see table of LED displays) Owing to the NC/NO contact combination in the read head, the evaluation unit expects to receive antivalent signal changes. If the actuators for all the connected read heads are in the response area, safety output 13/14 is closed. A door monitoring output 23/24 which is electrically separated from the safety output is also available to the user. The door monitoring output can be forwarded to a PLC for visual display. If an input to the evaluation unit does not have a read head connected, the bridges supplied must be inserted in the unused input terminals according to the connection diagram. If motor contactors are used, the switching contacts can be monitored by the evaluation unit via positively driven NC contacts. For this purpose, the CMS-E-BR offers an appropriate 1/2 connection for the feedback circuit. In the case of a monitored feedback circuit, safety output 13/14 is only activated if feedback circuit 1/2 was closed before the actuator was moved to the read head s response area. A start button must not be incorporated into the feedback circuit. In the case of unmonitored feedback circuits, the 2-pole bridge supplied with the evaluation unit must be connected to terminals 1/2. When the actuator is moved into the read head s response area, the entire unit is checked by the evaluation unit for faults. If, in the case of lateral approach, the actuator is moved slowly up to the read head, the two reed contacts are not switched simultaneously. If, after a certain delay time, the second reed contact has not switched either, the evaluation unit switches over to the blocked state. To cancel the blocked state, the actuator must again be moved beyond the Reset spacing. Since a certain delay time must be observed, the actuator has a minimum actuation speed in the case of the lateral approach. This switching principle ensures that faults such as welding of contacts and broken cable connections will be reliably detected. When the actuator is moved past the Switch Off Distance (see Combination options table) the evaluation outputs 13/14 and 23/ 24 will turn off. It will not turn on again until the actuator is moved past the Reset Distance and then back to within the switch-on distance s on, safety output 13/14 and door monitoring output 23/ 24 will switch. The CMS-E-BR is a self-monitoring system unit. Short circuits, faults in the read head or internal faults in the evaluation unit will be detected and the safety circuit will be reliably switched off. Internal linking of the relay in the evaluation unit prevents the machine starting up in the event of a fault. LED displays Function LED Colour State Operating voltage UB green On Outputs 23/24 and OUT red On 13/14 open OUT green Off Outputs 23/24 and OUT red Off 13/14 closed OUT green On Read head x (x = 1...4) Actuator in the response area!nc contact in the read head is open Dx1 green On!NO contact in the read head is closed Dx2 red Off Actuator not in the response area!nc contact in the read head is closed Dx1 green Off!NO contact in the read head is open Dx2 red On! If the green and red LED s light up simultaneously (e.g. D11 and D22), the relevant actuator is not fully in the response area.! If the actuators for all the connected read heads are in the response area (or 2-pole bridges have been fitted in the evaluation unit), safety output 13/14 and door monitoring output 23/24 are switched through (the green OUT LED lights up).! In the evaluation unit the green LED s are wired in series in the following sequence: D11 - D21 - D31 - D41. This means that the green LED (e.g. D41) can only light up if the upstream LED s D11/D21/D31 also light up.! If the actuation speed falls below the minimum speed, outputs 13/14 and 23/24 remain open.

A snap-in element to the back of the evaluation unit is used to fix the DIN rail (3 mm top hat rail). Notes for the electrical connection! All electrical connections have to be isolated from the power supply by means of a safety transformer to IEC/EN with a limitation of the output voltage in case of defect, or thrugh equivalent isolation measures.! Terminals A1 and A2 are reverse polarity protected for connection to the power supply and all outputs (safety and door monitoring output).! External fuses (4 A quick-action fuse) for relay outputs must be used.! All the output contacts must have an adequate protective circuit for capacitive and inductive loads.! If a common power supply is used, all the inductive and capacitive loads (e.g. relay contactors) connected to the power supply must be connected to appropriate interference suppressors.! All read head inputs that are not used must have the supplied bridges inserted according to the connection diagram. Safety precautions! Door monitoring output 23/24 for the CMS-E- BR evaluation unit may not be used as a safety output.! In the case of a monitored feedback circuit, safety output 13/14 is only switched through if feedback circuit 1/2 was closed before the actuator was moved to the read head s response area.! A start button must not be incorporated into the feedback circuit.! In the case of unmonitored feedback circuits, the 2-pole bridge supplied with the evaluation unit must be connected to terminals 1/2. 26
