• The Safety Interface Device is used in combination
with one or more Multiple Light Beam Safety Devices
or Safety Light Curtains to safeguard danger or hazard
areas.
• The control of the machine or system that is to be
safeguarded must be electrically influenceable. A
switch-off command initiated by an MSI must result in
an immediate shutdown of the dangerous movement.
• The "Reset" acknowledgment button for unlocking the
start/restart interlock must be mounted in such a way
that the entire danger zone can be seen from its
mounting location.
• Message outputs (state outputs) must not be used for
switching safety-relevant signals.
• The Safety Interface Device is designed for installation
in a cabinet or a protective housing with a protection
rating of at least IP 54.
• The 24 V DC ±20% power supply must guarantee safe
isolation from the mains voltage and be able to bridge
a power outage period of 20 ms.
• Depending on external wiring, dangerous voltages may
be present at the switching outputs. In addition to the
power supply, these must be switched off and safe-
guarded against being switched back on prior to all
work on the MSI-s.
• These operating instructions must be included with the
documentation of the machine on which the protective
device is installed so that they are available to the
operator at all times.
• In the event of changes to the MSI-s, all warranty
claims against the manufacturer of the Safety Interface
Device are rendered void.
• The safety distance between the AOPD and the point
of operation is to be maintained. It is calculated accor-
ding to the formulas for machine-specific C standards
or given in the general B1 standard ISO 13855. Both
the reaction time of the Test Monitoring Unit and the
braking time of the machine must be taken into ac-
count.
• Two switching contacts must always be looped into the
switch-off circuit of the machine. To prevent welding,
relay switching contacts must be fused/protected exter-
nally according to the technical data.
• The Safety Interface Device must be exchanged after a
maximum of 20 years. Repairs or the exchange of
parts subject to wear and tear do not extend the
service life.
• The Safety Interface Device satisfies the requirements
of safety category 4 acc. to ISO 13849-1. If, however,
an AOPD of a lower safety category is connected, the
total category for the given path of the control cannot
be higher than that of the connected AOPD.
• Cross connections between S1 and S2 are only detec-
ted by the MSI safety device if both time-staggered test
signal outputs, T1 and T2, are used for the connected
protective device(s) with relay output. AODPs of type 4
with safety-relevant transistor outputs and their own
cross circuit monitoring can be directly connected to S1
and S2.

2.1.2 Foreseeable misuse
Any use other than that defined under the "intended use"
or which goes beyond that use is considered improper
use!
e.g.
applications in explosive or easily flammable atmosphe-
res
Attention!
Such instances can jeopardize the health and lives of the
personnel operating the machinery and/or may cause
damage to property.
2.2 Competent personnel
Prerequisites for competent personnel:
• has a suitable technical education
• he knows the rules and regulations for occupational
safety, safety at work and safety technology and can
assess the safety of the machine
• he knows the instructions for the Safety Interface
Device and the machine
• has been instructed by the responsible person on the
mounting and operation of the machine and of the
Safety Interface Device
2.3 Responsibility for safety
Manufacturer and operating company must ensure that
the machine and implemented Safety Interface Device
function properly and that all affected persons are ade-
quately informed and trained.
The type and content of all imparted information must not
lead to unsafe actions by users.
The manufacturer of the machine is responsible for:
• safe machine construction
• safe implementation of the Safety Interface Device
• imparting all relevant information to the operating com-
pany
• adhering to all regulations and directives for the safe
starting-up of the machine

MSI-s 11
SPANISCH ITALIENISCH FRANZÖSISCH ENGLISCH DEUTSCH
The operator of the machine is responsible for:
• instructing the operating personnel
• maintaining the safe operation of the machine
• adhering to all regulations and directives for occupatio-
nal safety and safety at work
• regular testing by competent personnel (see
chapter 2.2 and 2)
2.4 Exemption of liability
Leuze electronic GmbH + Co. KG is not liable in the
following cases:
• Safety Interface Device is not used as intended
• safety notices are not adhered to
• reasonably foreseeable misuse is not taken into ac-
count
• mounting and electrical connection are not properly
performed
• proper function is not tested
• changes (e.g., constructional) are made to the Safety
Interface Device
2.5 Emergency STOP buttons to be connected
• It must be secured that the EMERGENCY STOP function
is always and immediate effective. In Chapter 5, Connec-
tion examples, there is a particular example illustrating
the connection of an EMERGENCY STOP button.
• When a two-channel Section Emergency Stop button is
connected, MSI is able to realize a Section Emergency
Stop function. Section Emergency Stop buttons con-
nected to the MSI only affect the safety ciruit that is
assigned to the AOPD. For this reason, it is referred to
as an Section Emergency Stop. The limited area of
effect of the button must be identified for the operating
staff in a manner that is cleary visible.

DEUTSCH ENGLISCH FRANZÖSISCH ITALIENISCH SPANISCH
3 System Configuration and Functions
3.1 System Configuration
Two microprocessors handle the redundant processing
of the signal sequences within the intelligent Modular
Safety Interface MSI. The results of the two processors
are continuously compared. If any deviations are found,
the safety-related outputs are immediately switched off
and the LED indicating an MSI failure lights up.
Sensor signals at inputs S1 and S2 are checked. Depen-
ding on which of the functions (as described below) are
selected, when the protected fields of all connected
AOPDs are free the MSI outputs switch automatically to
the ON state (without start/restart interlock) or remain in
the OFF state until the reset button has been pressed
and released (with start/restart interlock = standard ope-
rating mode).
On the output side, the MSI-s is equipped with two positive-
guided, normally open contacts.
The MSI safety interface comes in a 35 mm-wide slide-in
housing that holds the MSI-s module and the /R output
module. It is suitable for mounting on a grounded 35 mm
standard rail.
3.2 DIP Switch Settings
3.2.1 DIP Switch Settings for the MSI-s Module

DEUTSCH ENGLISCH FRANZÖSISCH ITALIENISCH SPANISCH
The MSI safety interface is factory-set for the operating
mode ”with start/restart interlock and dynamic external
device monitoring”. If this setting is changed, these
functions (i.e. the appropriate safety level) must be
guaranteed by other means.
• Types of interlocking functions
The start interlock function ensures that when the
system is switched on or when the supply voltage
returns, even if the protected field is free the safety-
related output contacts (OSSDs) do not automatically
go into ON state, but rather wait until the reset button
has been pressed and let go. The start/restart interlock
function prevents the OSSDs from automatically en-
tering the ON state when the protected fields of one or
more of the connected AOPDs are released again after
an interruption. Here as well, the reset button must be
pressed and let go to initiate the system.
• Types of External Device Monitoring
The function dynamic external device monitoring moni-
tors the relays connected downstream from the MSI
safety interface. Each time before the OSSDs switch to
the ON state, a check is made of whether the subse-
quent circuit elements have closed and reopened. If
they have not, the OSSDs of the MSI safety interface
remain in the OFF state. If the function static external
device monitoring is selected, a check is merely made
of whether the subsequent circuit elements are in an
open state. If they are, the start/restart interlock can be
initiated.
3.3.1.1 Operating Mode: With Start/Restart Interlock
– With Dynamic External Device Monitoring
External wiring requirements:
Start/restart interlock is no longer
active when the protected fields of
all connected AOPDs are free, the
downstream relays have returned
to their original state, and the reset
button is pressed and released.

3.3.1.4 Operating Mode: Without Start/Restart Inter-
lock – Without External Device Monitoring
External wiring requirements:
After the supply voltage is app-
lied, the OSSDs immediately go
into the ON state if all of the
protected fields of the connected
AOPDs are free. In this case, the
start/restart interlock function
and the dynamic monitoring of the downstream relays,
which may be required in order to maintain the safety
category, must be performed by other means.
3.3.1.5 Operating Mode: With Start/Without Restart
Interlock – Without External Device Monito-
ring
External wiring requirements:
After the supply voltage is app-
lied, the OSSDs remain in the
OFF state even if all of the pro-
tected fields of the connected
AOPDs are free.
When the protected fields of all connected AOPDs are
initially free, the OSSDs first enter the ON state when the
protected field of the AOPD connected at S1 (for Type 4:
S1 and S2) is interrupted and released. Only then do the
rest of the connected AOPDs respond to the interruption
and release of their own protected fields by switching the
OSSDs directly to the OFF and ON states.
In this case, the restart interlock function and the dyna-
mic monitoring of the downstream circuit elements, which
may be required in order to maintain the safety category,
must be performed by other means.
