1.4 Definition of terms
Output switching element (safety output) of the AS-i safety monitor
Element activated by the logic of the monitor which is able to safely switch off the down-
stream control elements. The output switching element may switch to or remain in the ON
state only when all components are functioning as intended.
Output circuit
Consists of the two logically connected output switching elements.
OSSD
The safe AS-i components and functional components assigned to an output circuit. They
are responsible for releasing the machine element which generates the hazardous move-
ment.
Integrated slave
Component in which sensor and/or actuator functions are grouped together with the slave to
form a unit.
Configuration operation
Operating state of the safety monitor in which the configuration is loaded and checked.
Master
Component for data transmission that controls the logical and temporal behavior on the AS-i
line.
Muting
Proper, application-intended, time-limited suppression of the protective field’s safety function.
Muting restart
Initiation of the override mode after a Muting fault (flashing Muting indicator).
Parallel Muting
Muting is initiated if 2 defined Muting sensor signals are activated within a defined time.
External device monitoring circuit (contactor monitoring)
The external device monitoring circuit allows the switching function of the contactors con-
nected to the AS-i safety monitor to be monitored.
Sequential Muting
Muting is initiated if 4 Muting sensor signals are sequentially activated in a defined order
(Muting sequence).

1.6 Brief description
The actuator-sensor interface (AS-i) has established itself as a system for networking primarily binary
sensors and actuators at the lowest level of the automation hierarchy. The high number of installed
systems, the ease of use and the reliable operating behavior also make the AS-i interesting in the area
of machine safety.
The safe AS-i system is intended for safety applications up to Category 4 / PL e in accordance with
ISO 13849-1. Mixed operation of standard components and safe components is possible.
The AS-i safety monitor monitors within an AS-i system the safe slaves which have been assigned
according to the configuration specified by the user with the configuration software. Depending on the
device model, up to two dependent or independent OSSDs, each with external device monitoring cir-
cuit, are available. In the event of a stop request or a defect, the AS-i safety monitor safely switches
off the system in protective operation mode with a maximum reaction time of 40ms.

Multiple AS-i safety monitors can be used within an AS-i system. In this way, a safe slave can be mon-
itored by multiple AS-i safety monitors.

System expansion - decentral, safe AS-i output slaves
With the system expansion focused on the safe connection of decentral, safe AS-i output slaves
acc. to IEC 61508 SIL 3, additional device models with a safe AS-i output are made available. These
models (ASM2E/1 / ASM2E/2) are used in the following applications:
1. Safe integration and monitoring of AS-i actuators or AS-i actuator groups, e.g. for enabling
motor starters or valve units through the safe AS-i output of the safety monitor.

An AS-i safety monitor can only monitor one actuator group.

2. Coupling of AS-i networks for the safe transmission of the state of an AS-i safety monitor
from one AS-i network to another AS-i network via the AS-i using the function of the AS-i safety
monitor as a safe AS-i input slave. This can be used, for example, for the creation of hierarchal
networks for the realization of a system stop which functions across an AS-i network or for the
implementation of a system restart from one location.

System expansion - Muting via AS-i
The "Muting" function range of the AS-i safety monitor offers the possibility of the proper, application-
intended and time-limited bridging of the protective function of the Safety Light Curtain/Multiple Light
Beam Safety Device/Transceiver used for access guarding the danger zone by connecting 2 or 4 Mut-
ing sensors, e.g if material is to be transported through the protective field into or out of the danger
zone.
The integration of the Muting function in the AS-i safety monitor offers a particularly economical and
flexible automation solution: the peripheral sensor equipment required for Muting evaluation of the
system, consisting of Muting and protective sensor, can be queried directly via AS-i.
Depending on the number of required AS-i addresses, multiple Muting ranges can be configured and
diagnosed on a system via a single AS-i safety monitor. The adjustable Muting modes can be
changed at any time by means of the asimon configuration software.

2 Safety
Before using the Safety Monitor, a risk evaluation must be performed according to valid standards
(e.g. ISO 14121, EN ISO 12100-1, ISO 13849-1, IEC 61508, EN 62061). The result of the risk assess-
ment determines the required safety level of the Safety Monitor (see table in section 2.1.1). For mount-
ing, operating and testing, document "AS-i Safety Monitor V 3.08 M" as well as all applicable national
and international standards, regulations, rules and directives must be observed. Relevant and sup-
plied documents must be observed, printed out and handed to the affected personnel.
Before working with the Safety Monitor, completely read and understand the documents applicable to
your task.
In particular, the following national and international legal regulations apply for the start-up, technical
inspections and work with safety sensors:
• Machinery directive 2006/42/EC
• Low voltage directive 2006/95/EC
• Electromagnetic compatibility directive 2004/108/EC
• Use of Work Equipment Directive 89/655/EEC supplemented by Directive 95/63 EC
• OSHA 1910 Subpart 0
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and Labor Protection Act
• Device Safety Act
2.1 Approved purpose and foreseeable improper operation
2.1.1 Proper use
• The Safety Monitor must only be used after it has been selected in accordance with the respec-
tively applicable instructions and relevant standards, rules and regulations regarding labor protec-
tion and occupational safety, and after it has been installed on the machine, connected,
commissioned, and checked by a competent person.
• When selecting the Safety Monitor it must be ensured that its safety-related capability meets or
exceeds the required performance level PLr ascertained in the risk assessment.
Notice!
For safety-related information you may also contact the local authorities (e.g., industrial in-
spectorate, employer's liability insurance association, labor inspectorate, occupational safe-
ty and health authority).
Warning!
A running machine can cause severe injuries!
Make certain that, during all conversions, maintenance work and inspections, the system is
securely shut down and protected against being restarted again.

Safety
18 Operating manual for the AS-i safety monitor V 3.08 M
Edition: 01/2010
The following table shows the safety-related characteristic parameters of the AS-i Safety Monitor.
• The Safety Monitor is used to monitor the mandatory E-STOP function for all non-hand-operated
machines (Stop Category 0 or 1), the dynamic monitoring of the restart function and contactor
monitoring.
• Settings and changes of the device configuration via PC and asimon configuration software must
