2.1 Product information
This system manual applies to the following Pepperl+Fuchs GmbH equipment:
2.1.1 AS-i Safety Monitor for 2 AS-i circuits
The AS-i Safety Monitor in a stainless steel enclosure is an E-STOP switching de-
vice which monitors safety configured slaves and correct function of the network.
The safety unit provides 4 inputs which can be defined as either EDM or as
START inputs.
The unit features two hierarchically equal AS-i circuits and four output switching
elements (two safety relays and two semiconductor outputs).
Features:
• Greater computing power to allow more function modules
• Graphical display for better diagnostics
• Optional storing of configuration data on an interchangeable memory card.
• EDM & START inputs can be defined freely
2.2 Brief description
The Actuator-Sensor-Interface (AS-i) has been established as a system for net-
working primarily binary sensors and actuators on the lowest level of the automa-
tion hierarchy. The large number of installed systems, ease of use and reliable
operating behavior make AS-i also ideal for machine safety applications.

AS-i Safety Monitor for 2 AS-i circuits
General
The safe AS-i system is intended for safety applications up to Category 4/SIL 3.
Mixed use of standard components and safety components is possible.
The AS-i Safety Monitor performs monitoring within an AS-i system of the user-
assigned safety slaves based on the configuration the user has set using configu-
ration software. In case of a Stop request or a fault condition, the AS-i Safety Mo-
nitor safety shuts off the system with a response time of maximum 40 ms.
Abb. 2-1. Safety configured and standard components in an AS-i network
Multiple Safety Monitors can be used within one AS-i system. A safe slave can be
monitored by more than one AS-i Safety Monitor.

3. Safety
3.1 Safety standard
The AS-I Safety Monitor has been developed, manufactured, tested and submit-
ted for type testing in accordance with the safety standards prevailing at the time
of testing. The safety requirements per Category 4 in accordance with EN 954-1,
SIL3 in accordance with EN 61 508 and Performance Level “e” in accordance
with EN ISO 13 849-1 are met by all devices.
Following a risk analysis you can sue the AS-I Safety Monitor in accordance with
its safety category as a shut-down protection device for protecting hazardous
areas.
3.2 Intended use
3.2.1 Conditions of use
The AS-I Safety Monitor has been developed as a shut-down protection device
for protecting hazardous areas on powered equipment.
3.2.2 Residual risks (EN 292-1)
The circuits suggested in this Manual have been tested and verified with the gre-
atest care. The prevailing standards and regulations are met when using the
components and wiring shown. Residual risks remain if:
• There are any deviations from the suggested wiring concept which may result
in the connected safety-relevant assemblies or protective devices not being
incorporated or only insufficiently incorporated into the safety circuit.
• The operator does not follow the prevailing safety regulations for operation,
setting and maintenance of the machine. Machine inspection and mainte-
nance intervals must be strictly observed.
3.3 Areas of application
The AS-I Safety Monitor, when properly used, enables the operation of sensor-
controlled personal protection equipment and additional safety components.
Information!
A detailed listing of the values for probability of failure (PFD values) can be found in
section Safety-relevant characteristic data.
Attention!
Protection of operating personnel and equipment is not provided is the device is
not used in accordance with its intended use.
Attention!
Manipulation of and changes to the devices other than expressly described in this
Manual are not permitted.

AS-i Safety Monitor for 2 AS-i circuits
Safety
The device also assumes the mandatory E-STOP function (Stop Category 0 or 1)
for all non-manually operated machines, dynamic monitoring of the restart func-
tion and the protection monitoring function.
Examples for use of the AS-I Safety Monitor:
The device is used economically in machines and equipment in which the stan-
dard AS-I bus is the local bus. Using the Safety Monitor as a bus component al-
lows already existing AS-I bus configurations to be easily expanded, and safety
components having the corresponding AS-i Safety at Work interface can be inser-
ted without difficulty. If there is no AS-I Safety at Work interface on the safety
component, so-called coupling modules can be used to establish the connection.
Existing AS-I masters and AS-I power supplies can be used as well.
There are no industry-specific restrictions. Some of the key applications are listed
below:
• Machine tools
• Expanded machining centers with multiple control elements and safety sen-
sors for wood and metal processing
• Printing and paper processing machines, trimming machines
• Packaging machinery, both stand-alone and as systems
• Food and beverage machinery
• Workpiece and bulk material conveying systems
• Rubber and plastics industry processing machinery
• Automatic assembly and handling equipment.
3.4 Organizational requirements
3.4.1 Documentation

AS-Interface
Spezifications
Upon activation of safety light barrier S1-2, the relay safety output of safety moni-
tor SM1-2 is controlled.
Calculation of the AS-i relevant system reaction time:
tSystem total a) = tR S1-2 + tR System = 18ms + 40ms = 58ms

AS-i Safety Monitor for 2 AS-i circuits
Spezifications
Upon locking of the EMERGENCY-OFF switch S2-1, the motor starter is cont-
rolled via the safe AS-interface output of safety monitor SM2-1.
Calculation of the AS-interface-relevant system reaction time:
tSystem total b) = tR S2-1 + tR System + tR A2-1 = 100ms + 40ms + 50ms = 190ms

AS-Interface
Spezifications
Upon locking of the EMERGENCY-OFF switch S1-1, the relay output of safety
monitor SM2-1 is controlled via the coupling of the safe AS-interface output of
safety monitor SM1-1.
Calculation of the AS-i relevant system reaction time:
tSystem total c) = tR S1-1 + tR System ASI1 + tR System ASI2 = 100ms + 40ms +
40ms = 180ms

Warning!
Cover the top of the AS-I Safety Monitor when doing any drilling work above the unit.
No particles, especially metal chips, should be allowed to enter the housing, since this
could cause a short circuit.

Attention!
The AS-I power supply for the AS-I components must have isolation per IEC 60 742
and be able to handle momentary power interruptions of up to 20 ms. The power sup-
ply for the 24 V supply must also have isolation per IEC 60 742 and be able to handle
momentary power interruptions of up to 20 ms. The maximum output voltage of the
power supply must also be less than 42 V in case of a fault.
