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
The safety switch is used in AS-Interface systems (to EN 62026-2) for monitoring the position of moveable safety guards to EN 60947-5-1.
The combination of the AZ 16 AS safety switch, the AZ 15/16 actuator and safety monitor ensures the safe monitoring of the condition of the corresponding safety guard. To actuate the AZ 16 AS safety switch, only the coded AZ 15/16 actuators must be used.
The safety function consists in safely switching off the code transmission when the safety guard is opened and maintaining the safe switched off condition for as long as the safety guard is open.
An AS-Interface Safety at Work component functions on the basis of an individual code generator (8 x 4 bit). This safety code is cyclically transmitted over the AS-i network and monitored by a safety monitor.
The component status can be evaluated through a PLC with
AS-Interface master. The safety-related functions are enabled by means of the AS-i safety monitor.
The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level.
LED display
The LEDs have the following meaning:
Green LED: AS-Interface supply voltage
Red LED: AS-Interface communication error or slave address = 0
Yellow LED: Status enable

3. Mounting
3.1 General mounting instructions
The mounting dimensions are indicated at the rearside. 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 by means of slot sealing plugs (AZ 15/16 -1476-1 available as accessory) after fitting.
Please observe the remarks of the standards EN ISO 12100,
EN ISO 14119 and EN ISO 14120.
Mounting of the actuators: See mounting instructions actuators.
The actuator must be permanently fitted to the guard system and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling, pinning).

5. Configuration
5.1 Programming the slave address
The slave address is programmed through the M12 connector.
Any address from 1 to 31 can be set by means of the AS-i bus master or a hand-held programming device.
5.2 Configuration of the safety monitor
The AZ 16 AS must be configured in the monitoring device by default as a double channel forced module (refer to ASIMON manual).
Double channel forced
• Optionally with startup test
• Optional with local acknowledge
The configuration of the safety monitor must be tested and confirmed by a qualified and authorised safety expert/safety engineer.
6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety components must be tested.
The following conditions must be previously checked and met:
1. Check the switch enclosure for damage
2. Fitting and integrity of the cable connections
3. Connect the AZ 16 AS to the AS-Interface network
4. Set the parameter outputs to "1111" (0xF)
5. Check the proper function of the AZ 16 AS system and AZ 15/16 actuator with configured safety monitor
6.2 Maintenance
In case of correct installation in accordance with the above-described instructions, the component requires little maintenance. A regular visual inspection and functional test, including the following steps, is recommended:
1. Remove particles of dust and soiling
2. Fitting and integrity of the cable connections
Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for instance by means of replacement actuators.
Damaged or defective components must be replaced.
7. Disassembly and disposal
7.1 Disassembly
The safety switchgear must be disassembled in a de-energised condition only.
