We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply with this operating instructions manual. The manufacturer shall accept no liability for damages resulting from the use of unauthorised spare parts or accessories. For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the device are strictly forbidden; the manufacturer shall accept no liability for damages resulting from such invasive work, arbitrary repairs, conversions and/or modifications to the device. 2. Product description 2.1 Ordering code This operating instructions manual applies to the following types: AZ 415-➀ZPK-➁ No. Option Description ➀ S1 S2 02/11 2 NC 1 NO / 1 NC 02/02 2 NC 2 NC 02/20 2 NC 2 NO 11/11 1 NO / 1 NC 1 NO / 1 NC ➁ 1637 Gold-plated contacts Only if the information described in this operating instructions manual are realised correctly, the safety function and therefore the compliance with the Machinery Directive is maintained. 2.2 Special versions For special versions, which are not listed in the order code below 2.1, these specifications apply accordingly, provided that they correspond to the standard version. 2.3 Purpose Safety switches with separate actuators are suitable for movable safety guards, which need to be closed to ensure the necessary operational security. The safety switches are used for applications, in which the hazardous situation is terminated without delay when the safety guard is opened. When the safety guard is opened, the NC contacts are positively opened and the NO contacts are closed. Operating principle By closing the safety guard, switch insert S1 is released and switch insert S2 actuated (differentiated operating principle). When the actuator is fully inserted, the safety guard is not subject to any ejection force. The safety switchgears are classified according to ISO 14119 as type 2 interlocking devices. The user must evaluate and design the safety chain in accordance with the relevant standards and on the required safety level. The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant standards. 2.4 Technical data Standards: IEC 60947-5-1, BG-GS-ET-15 Enclosure: light-alloy diecast, paint finish Actuator: zinc-plated metal / aluminium Coding level according to ISO 14119: low Protection class: IP67 to IEC 60529 Contact material: Silver Contact types: Change-over contact with double break, type Zb or 2 NC contacts, with galvanically separated contact bridges Switching system: A IEC 60947-5-1; slow action, NC contact with positive break Connection: screw terminals Cable section: 0.75 … 1.5 mm² (incl. conductor ferrules) Cable entry: 2 × M20 x 1.5 Rated impulse withstand voltage Uimp: 4 kV Rated insulation voltage Ui: 250 V Thermal test current Ithe: 6 A Utilisation category: AC-15 / DC-13 Rated operating current/voltage Ie/Ue: 4 A / 230 VAC 4 A / 24 VDC Max. fuse rating: 6 A gG D-fuse Required short-circuit current: 1000 A Positive break travel: 3.8 mm Positive break force: min. 31 N Ambient temperature: −25 °C … +70 °C Mechanical life: > 1 million operations Latching force: 80 … 400 N (adjustable) Actuating speed: max. 0.2 m/s Max. switching frequency: 2000/h 2.5 Safety classification Standards: ISO 13849-1 Envisaged structure: - Basically: applicable up to Cat. 1 / PL c - With 2-channel usage and fault exclusion mechanism*: applicable up to Cat. 3 / PL d with suitable logic unit B10d NC contact: 2,000,000 B10d NO contact at 10% ohmic contact load: 1,000,000 Service life: 20 years * If a fault exclusion to the 1-channel mechanics is authorised.

If multiple safety components are wired in series, the Performance Level to ISO 13849-1 will be reduced due to the restricted error detection under certain circumstances.

The mounting holes are accessible after removal of the cover. The enclosure must not be used as an end stop. Any mounting position. The mounting position however must be chosen so that the ingress of dirt and soiling in the used opening is avoided. Mounting of the actuators: See mounting instructions actuators. Please observe the remarks of the standards ISO 12100, EN 953 and ISO 14119. The safety component and the actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling, pinning). 3.2 Dimensions All measurements in mm. 28¤ 6,5 7,8 8 22,3 20 M20x1,5 8,8 A 88 84,6 46,5 103,6 26,8 29,5 ¤ 11 Key A Setting screw ball latch: 80-400 N 3.3 Adjustment In the unlocked condition, the safety guard is kept in a closed condition by the adjustable ball latch. By rotating a hexagonal key wrench clockwise, the desired holding force can be increased; if the hexagonal key wrench is rotated counterclockwise, the holding force is decreased. The holding force must always be set as low as possible. 4. Rear side Electrical connection 4.1 General information for electrical connection The electrical connection may only be carried out by authorised personnel in a de-energised condition. The contact labelling can be found in the wiring compartment of the switch. For the cable entry, suitable cable glands with an appropriate degree of protection must be used. Non-used input openings must be sealed by means of threaded plugs. After wiring, dust and soiling must be removed from the wiring compartment. The conductors of the connecting cables must not obstruct the movement of the switching lever. Maximum tightening torque for the screws: Cover 0.6 + 0.1 Nm; bottom cover 0.7 + 0.1 Nm 4.2 Contact variants Contacts are shown with safety guard closed.
