Operating instructions
Emergency stop Station
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. The entire concept of the control system, in which the safety component is integrated, must be validated to EN ISO 13849-2.
There are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation and maintenance are observed.
1.6 Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant components cannot be excluded. The relevant requirements of the standard EN 1088 must be observed.
1.7 Exclusion of liability
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.

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
The emergency stop station of the series NAS 311 AS is used on machinery and plants as a safe command device to generate a safe signal initiating the shutdown of a hazardous movement when actuated.
The NAS 311 AS must only be used in combination with the AS-i ASM safety monitor.
The integrated AS-i module is used to detect safety-relevant switching conditions of mechanical contacts.
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 the ASM safety monitor.
NAS 311 AS
The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level.
Maintenance: Please observe that the safety function must be triggered at least once a year to test the system!

4.1 General information for electrical connection
The electrical connection may only be carried out by authorised personnel in a de-energised condition.
The NAS 311 AS emergency stop station is supplied from the AS-
Interface cable.
The connection to the AS-Interface system is realised through an M12 connector. The wiring configuration of the M12 connector is defined as follows (to EN 50295): spare

AS-Interface - (blue)
AS-Interface + (brown)
1
2 spare
5. Functions and 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.
NAS 311 AS
5.2 Configuration of the safety monitor
The NAS 311 AS emergency stop station must be configured in the
ASIMON configuration software with the following monitoring devices.
(also refer to the 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.
5.3 Status signal "safety release"
The "safety release" status signal from a Safety at Work slave can be cyclically queried by the control system through the AS-i master. To that effect, the 4 input bits with the varying SaW code of a Safety at
Work slave are evaluated through an OR operation with 4 inputs in the control system.
5.4 Diagnostic functions
LED indications (internal)
The LED on the internal AS-i module have the following meaning:
LED green (PWR): AS-Interface supply voltage
LED red (FAULT): AS-Interface communication error or slave address = 0 or periphery error
LED yellow (S-I1): Contact 1
LED yellow (S-I2): Contact 2
6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety components must be tested. The following conditions must be checked and met:
• Correct fixing of the fitted component.
• Check the integrity of the cable entry and connections.
• Check the emergency stop station for damage.
6.2 Maintenance
The function of the emergency stop station must be tested in regular intervals.
Maintenance: Please observe that the safety function must be triggered at least once a year to test the system!
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.
