Product Description

Ordering code

• Product type description: AZ 16-(1)ZV(2)K-(3)-(4)-(5)

Special versions
For special versions, that are not listed in the ordering code, these specifications apply accordingly, provided that they correspond to the standard version.

Purpose

• The safety switches with separate actuators are suitable for sliding, hinged, and removable safety guards, which need to be closed to ensure the necessary operational safety.
• 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.

When the safety guard is opened, the NC contacts are positively opened and the NO contacts are closed.

• The safety switchgears are classified according to EN ISO 14119 as type 2 interlocking devices.
• CAUTION: The user must evaluate and design the safety chain per the relevant standards and the required safety level.
• WARNING: The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant standards.

Warning about misuse

WARNING: in case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant components cannot be excluded. There are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation, and maintenance are observed

Note about the safety classification

• Suitable up to Cat. 1 / PL c.
• With 2-channel usage with a fault exclusion mechanism (if a fault exclusion to the 1-channel mechanics is authorized) and suitable logic applicable up to Cat. 3 / PL d
• (Determined values can vary depending on the application-specific parameters hop , d op, and tcycle as well as the load.)

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

Mounting

General mounting instructions

WARNING: Please observe the relevant requirements of the standards ISO 12100, ISO 14119 and ISO 14120.

• The mounting dimensions are indicated on the rear of the component. 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. The unused openings must be sealed employing slot sealing plugs (AZ 15/16 – 1476-1 available as accessory) after fitting.

Mounting of the actuator

See operating instructions Actuator.

• WARNING: The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling of the screw heads). See operating instructions Actuator.
• WARNING: The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling of the screw heads.

Dimensions

All measurements in mm.

Electrical connection

General information for electrical connection

WARNING: The electrical connection may only be carried out by authorized personnel in a de-energized condition.
The contact labeling can be found in the wiring compartment of the switch. Appropriate cable glands with a suitable degree of protection are to be used.

Settle length x of the conductor: 6 mm

After wiring, dust and soiling must be removed from the wiring compartment. The safety switch is double-insulated. The use of a protective ground connector therefore is not authorised.

Contact Options
Contacts are shown with the safety guard closed. All NC contacts have positive break .

Set-up and maintenance

The safety function of the safety components must be tested. In the case of correct installation and adequate use, the safety switchgear features maintenance-free functionality. A regular visual inspection and functional test, including the following steps, is recommended:

1. Check for free movement of the actuating element
2. Check cable entry and connections
3. Check the switch enclosure for damage
4. Remove particles of dust and soiling

WARNING: Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for instance using replacement actuators. Damaged or defective components must be replaced.

Disassembly and disposal

Disassembly
The safety switchgear must be disassembled in a de-energized condition only.

Disposal
WARNING: The safety switchgear must be disposed of appropriately by the national prescriptions and legislation.
