certificate of professional training, or who, by extensive knowledge, training or
experience, has successfully demonstrated the ability to solve problems relating to
the subject matter and work.».
Use of a muting function requires special precautions by the safety system machine
controller, installer, operator and employer. The following is only a partial list of
requirements when utilizing muting and is not intended to be a complete guide to
muting standards. The employer must contact the local safety authority for specific
requirements regarding the machine, machine controller and safety related control
system. Schneider provides the following information for user reference only and
makes no claim regarding the accuracy, completeness or effectiveness for a specific
application from any organization:
Muting of the light curtain is only permitted during the nonhazardous portion of
the machine cycle.
If the machine tool has reversing capability where a muting hazard is possible the
control shall include an automatic means through which muting is only permitted
in the forward direction.
Selection of the muting feature shall be by a key-operated switch under
supervisory control by the employer.
One or more visual indicator(s) shall be provided which are illuminated when the
light curtain is in a muted condition.
Any fault condition of the mute indicator(s) shall not allow the light curtain to enter
a mute condition.

Features
The XPSLCM1150 Mute Module is a Category 4 safety device that interfaces
between a machine and certain protective safety devices to temporarily suspend
those devices during the non-hazardous portion of the machine cycle. It conforms
with EN 954-1 and has been certified to IEC 61496-1.
Fast 1 ms response time.
Works with either 1 or 2 safety devices (safety light curtain, safety controller, etc.)
Two-channel mute sensor inputs for 2, 3 or 4 PNP-type electro-optic sensors, or
limit switches or other sensing devices.
LED indications for individual input and output status.
Two-digit diagnostic display.
External mute indication for operator awareness.
12 08/2007
Applications
Automatic conveyer, stacker and palletizing machines.
Mechanical and hydraulic presses with automatic or manual feed with the muting
function is only used in the non-hazardous portion of the press cycle.
When the mute mode is disabled, the XPSLCM1150 outputs are the same as those
of the connected safety devices. Any entry into the guarded area will result in a stop
signal being sent to the guarded machine.
The XPSLCM1150 provides two "mute safety channels", each accepts a single
safety device, and either two, three or four mute sensors to activate the mute mode.
The mute mode is active when the correct sequence of mute sensor input signals is
achieved.
Each safety device output must be capable of supplying two 24 V (PNP) output
signals when the sensing field is clear. Mute sensors must have PNP type outputs,
sensor pairs are made-up of both "dark operate" and "light operate" sensors.
An indicator lamp for each safety channel is required to illuminate anytime the
XPSLCM1150 is in the mute state. These lamps must be visible to personnel in the
immediate area. The XPSLCM1150 monitors the lamp circuit to ensure the indicator
is operational.

Description of Controls
IMPROPER INSTALLATION
Muting can disable the safety functions of a machine. The proper installation,
checkout and operation of a machine and muting system; in accordance with all
applicable laws and standards, is critical to the safe operation of the machine.
Failure to comply with these instructions may result in severe injury to personnel.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
WARNING
Power
requirements
The XPSLCM1150 requires a dedicated power supply of 24 V +/- 10 %, providing
a minimum of 2 amperes that meets the requirements of IEC61496-1 and
IEC60204-1, part number ABL8RPS24030 or equivalent.
System Common Return
For proper operation, the power supply common, (0 V ), must be connected to
each of the components in the system, including start/enable switches, EDM/MPCE
monitor, all OSSD and Auxiliary loads.
Chassis Ground or Protective Earth (PE) Connection
The chassis ground terminal of the XPSLCM1150 must be connected to the earth
ground of the installation site to ensure protection from electrical interference and
high voltage transients.
14 08/2007
XPSLCM1150
input devices
Sensor Inputs
The XPSLCM1150 module accommodates up to two independent channels
identified as Channel 1 & Channel 2. Each channel is comprised of one safety input
device and either two, three, or four mute input sensors.
Safety Input Devices (OSSD Inputs)
The XPSLCM1150 supports safety devices such as safety light curtains, safety
controllers or other safety-rated devices that provide two 24 V inputs into the
XPSLCM1150 whenever their protected area is clear.
Note: If using an input from a relay-type safety device, the two OSSD signals must
switch to the On and Off state within 300 msec of each other to be recognized as
proper OSSD inputs.
Mute Sensor Inputs
Muting is controlled by two or more separate input sources. These devices can be
optical, inductive or mechanical. Sensors S1A, S1C, S2A & S2C must have «DarkOn» PNP type outputs, nominal 24 V when Ok to mute. Sensors S1B, S1D, S2B
& S2D must have «Light-On» PNP type outputs, nominal 0 volts (no current flow)
when Ok to mute.
WARNING
IMPROPER SET UP OR INSTALLATION
You must have at least two independent mute sensors to activate the mute circuit.
A single device with multiple outputs such as single limit switch, is inadequate as a
mute sensor since its failure can remain undetected. Failure to comply with this
requirement may cause the muting circuit to activate at the incorrect part of the
machine cycle. Serious injury to personnel could result.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Mute Enable / Disable
A single selector switch is used to enable the XPSLCM1150 to detect the mute input
sensors, or disable the XPSLCM1150 from entering the mute state. When in the
disable position all muting errors are cleared from the diagnostic display.
08/2007 15
Start Switch
A push-button switch is required to reset the XPSLCM1150 from a Start/Interlock
condition, a fault interlock, or allow the Bypass feature to be used. The input is DIP
switch selectable for N/O or N/C operation.
WARNING
IMPROPER INSTALLATION OF THE START BUTTON
The Start switch shall be located outside of the safeguarded area such that it
cannot be reached from within the safeguarded area. The location must allow
complete visibility of the guarded area. The operator must ensure that the
safeguarding zone is clear before press & release of Start.This prevents the
machine or muting function from starting while personnel may be in the hazardous
area and avoids possible serious injury to personnel.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
16 08/2007
XPSLCM1150
outputs
WARNING
IMPROPER OUTPUT OPERATION
Muting is only allowed during the non-hazardous portion of the machine cycle! A
muting application must be designed so that no single component failure can
prevent the stop command or allow subsequent cycles until the failure is corrected.
(USA standard OSHA 1910.217(c)(3)(iii) (d), ANSI B11.19-1990 section 4.2.3.3.7)
Failure to comply with this requirement may cause the muting circuit to activate at
the incorrect part of the machine cycle, serious injury to personnel could be
resulted.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Output Signal Switching Devices (OSSD’s)
The XPSLCM1150 uses two solid-state outputs to send a stop signal to the guarded
machine. When the XPSLCM1150 is in the normal Run mode with the safety
device(s) clear, or in the Mute mode regardless of the safety device(s) status, the
OSSD outputs are turned on, sourcing 24 V @ a maximum of 625 mA.
Solid-state outputs achieve their safety ratings by periodically switching the output
state and verifying that the device did indeed switch. This operation is performed
periodically and is essentially transparent to the machine control circuit.
WARNING
IMPROPER OUTPUT SET UP
You Must Use both OSSD safety outputs from the XPSLCM1150! Each output
must be wired such that it is capable of stopping the guarded machine. Failure to
use both XPSLCM1150 safety outputs may prevent the machine from stopping,
resulting in possible severe injury to personnel.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Auxiliary Outputs
The XPSLCM1150 provides non-safety auxiliary outputs in both PNP and NPN
configurations. The PNP output source 24 V @ 500 mA, the NPN output sinks
up to 100 mA.
The auxiliary outputs are user selected to either follow the OSSD outputs, or activate
when a fault condition is detected.
08/2007 17
Mute Lamp Outputs 1 & 2
A visible mute lamp is required for each channel of the XPSLCM1150 to indicate the
mute function is active. Mute Lamp outputs are NPN current sinking inputs. Each
input is monitored to ensure 40-300 mA is flowing through the circuit when Mute is
activated. If the required current is not detected, then the XPSLCM1150 will not
enter the Muting state and will display diagnostic codes. If a current is detected when
the mute function is NOT activated, the XPSLCM1150 will enter the Lockout state.
WARNING
IMPROPER MUTE INDICATION
An indication that the protected area is muted must be provided and readily
observable to the machine operator. The mute lamp is an important warning device
to the machine operator, indicating that muting is active.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Mute Indicator Auxiliary Outputs
Mute Auxiliary and Mute Armed functions are available as non-safety-rated outputs.
Each is configured as NPN sinking at a maximum of 100 mA. Mute Aux will indicate
whenever the XPSLCM1150 is in the Muting state. Mute Armed will indicate the
XPSLCM1150 is Mute Enabled.
EDM/MPCE Monitor
The XPSLCM1150 OSSD outputs are designed to connect directly to the machine
primary control element, or EDM/MPCE. EDM/MPCE monitoring is the capability to
directly monitor machine control devices and ensure their operation coincides with
the commands of the XPSLCM1150.

Adjusting the safe mounting distance
Using the
XPSLCM1150
without
mechanical
relays
Using the
XPSLCM1150
with safety
mechanical
relays
The XPSLCM1150, when used without mechanical relays, will add 1 millisecond
(0.001 sec) to the overall response time of the safety control system. This will
increase the safe mounting distance of the safety sensing device. See the
installation manual of the safety sensing device for further information on calculating
the proper safeguarding distance.
The XPSLCM1150 itself adds 1 millisecond (0.001 sec) to the response time of the
safety control system. Additionally, you must also add the response time of the
mechanical relays to determine the total impact on the safety control system. This
will increase the safe mounting distance of the safety device.
The XPSLCM1150 should only be used with safety rated mechanical relays
employing force guided contacts. Contact the relay supplier for the safety rating
suitability and response time.
Refer to the installation manual of the safety sensing device for further information
on the safe mounting distance.

Application information
Principle The following section contains several application examples of how the
XPSLCM1150 may be used with various arrangements of sensors to start and end
the muting sequence.
Although photoelectric sensors are used in the example, other types of sensors,
such as limit switches, inductive proximity sensors and ultrasonic sensors may be
used as sensor inputs to the XPSLCM1150, provided that they met the electrical
requirements of XPSLCM1150 input devices, p. 15.
Note: Schneider provides the following application examples for user reference
only and makes no claim regarding the accurary, completeness or effectiveness for
a specific application from any organization.
WARNING
IMPROPER INSTALLATION OF SENSORS
The system installer and employer are responsible for the proper selection,
installation and orientation of the muting sensors are critical to ensure that muting
can never be initiated by personnel attempting access through the safeguarding
device. Serious injury to personnel may result.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
38 08/2007
Selection and
orientation of the
muting sensors
The object of the correct muting sensor selection and orientation is to always
recognize the presence of the workpiece material as the intended means to start or
stop the muting sequence. The presence of any person in the detection zone of the
muting sensors must never be able to initiate a muting sequence, or otherwise
bypass the safe guarding device.
The proper selection, installation and orientation of the muting sensors are the sole
responsibility of the employer and installer. The following recommendations must be
observed, especially in conveyorized applications.
The muting sensors should detect the material, and not the transportation means,
such as a pallet, cart or other transport device. Ensure that a person on the
transport device cannot initiate muting and enter the hazardous area.
Do not allow interruption in the sensing of the material while passing the muting
sensors. The detection of the material should be continuous over its length.
If using photoelectric sensors, do not allow reflective material to interrupt or cause
optical short circuits among different sensors. Likewise, do not allow sensors in
adjacent areas to interfere or provide false indication.
Position the sensors such that before a new load of material is detected by the
first sensor, the prior material has passed the last sensor and all muting sensors
are deactivated for a period of time.
Consider the overall speed and cycle the material as it moves through the
process. Time must be allowed for evaluating the muting sensors¡¯ output prior
to the material reaching the safeguarding device.
Access by persons into the hazardous area of the machine must be prevented or
detected such that a safeguarding device is able to send a stop signal to the
machine before entering into the hazardous area. Other safeguarding methods,
such as physical barriers or fences, may be necessary.
The muting position (of the sensors) shall be secured against unauthorized
adjustment by provision of special tools, key entry, electronics passwords and the
positioning and mounting of associated limit switches.

Description of the bypass-allowed feature
Principle The XPSLCM1150 allows supervisory personnel to momentarily override the
machine stop signal of the XPSLCM1150. This function is used during instances
where processing sequence operations did not allow an automatic transition to the
muting state and the XPSLCM1150 safety outputs are in the Off state.
Signals in
bypass-Allowed
state
Enter the
bypass-Allowed
state
The XPSLCM1150 signals that it is in the Bypass-Allowed state by the following
indications:
The mute lamp of the effected safety channel will flash at about a 1-second
interval.
The Mute Aux output will switch between active and inactive at about a 1 Hz rate.
The diagnostic display will show a code of 03.
The XPSLCM1150 will enter the Bypass-Allowed state under the following
conditions:
Redundant DIP switches must be set to enable Bypass-Allowed feature to occur.
The mute enable inputs are active.
The light curtain safety outputs (OSSD) are in the Off state and a minimum of one
mute sensor is active in the effected safety channel.
50 08/2007
Transition to the
Muting state
To allow the XPSLCM1150 to transition to the Muting state the supervisory
personnel must press-and-release the start button. When entering the Muting state
through the Bypass-Allowed feature the following will occur:
The mute lamp of the effected safety channel will now be On continuously.
The Mute Aux output will now be continuously in the active state.
The diagnostic display will show a code of 02.
If the light curtain is clear of obstructions before all of mute sensors have cleared
then the XPSLCM1150 will leave the Muting state and enter the Machine Run
state. Note, all of the mute sensors must clear for the XPSLCM1150 to
automatically enter the Muting state during the next process cycle.
If all of the mute sensors clear of obstructions before the light curtain has cleared
then the XPSLCM1150 will leave the Muting state and enter the Machine Stop
state.
When the Muting state is entered through the Bypass-Allowed state then the
maximum time for the XPSLCM1150 to be continuously in the Muting state is 10
minutes.
If the 10 minute time limit is exceeded the XPSLCM1150 will automatically
change from the Muting state to the Bypass-Allowed state.
There is no limit on the number of times that the XPSLCM1150 can enter the
Bypass- Allowed state and then with the press-and-release of the Start button
into the Muting state.
08/2007 51

WARNING
IMPROPER TEST PROCEDURE
The following test procedure MUST be performed by qualified personnel:
Following system installation.
In accordance with the employer’s regular inspection program.
Immediately following any maintenance, adjustment or other modification to any
system component.
Testing ensures that the safety devices and associated machine control system
work together to properly stop the guarded machine. Failure to perform these
procedures could result in serious injury.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Note: It is the user’s responsibility to ensure that the installation conforms to all
federal, state, local and company regulations pertaining to safe operation of the
equipment.

Installation
checkout
Step Action
1 Disable the guarded machine.
2 Visually inspect the machine to ensure that access to the danger point is only
through the area (s) protected by the safety light curtain(s).
3 Verify that the mounting distance of the safety light curtain(s) is equal to or
greater than the minimum safety distance required according to the EN 999 and
ANSI Minimum Safe Distance calculation. (See (See Adjusting the safe
mounting distance, p. 19).
4 Check the overall system for damage, security of electrical cabling and wiring,
or other hazards.
CAUTION
IMPROPER INSTALLATION
If any of the above requirements are not met, immediately lock out the machine and
initiate the necessary corrective action.
Failure to follow these instructions can result in injury or equipment damage.

Normal
operation with
muting disabled
Step Action
1 Disable the guarded machine. Apply power to the XPSLCM1150 system.
2 Ensure the Muting Enable switch is in the OFF (disabled) position.
3 Using the proper size test object for each light curtain, test the protected area of
the light curtain. Test the area by moving completely through the field, top to
bottom, ensuring that all the areas between transmitter and receiver are
completely tested. The light curtain should remain blocked at any point with the
test object present in the sensing field.
4 Enable the machine and initiate a start. Interrupt the sensing zone with the
correct test object and verify the machine stops immediately. Never attempt to
insert the test object directly into the danger area! If the machine fails to stop,
discontinue the testing and lock out the machine. Investigate and correct prior
to re-testing.
5 With the test object present in the field, verify the machine cannot start.
6 Repeat tests for all safety light curtains installed.
08/2007 59
Mute operation
(muting enabled)
Step Action
1 Complete testing requirements in Installation checkout, p. 58 and Normal
operation with muting disabled, p. 59
2 Disable the guarded machine and apply power to the system.
3 Set the Muting Enable Switch to the ON position.
4 Mute the system by blocking the correct sensors at the proper intervals (<3
seconds between sensors) and logical order. (Refer to the appropriate system
timing diagram) Verify that the associated mute inputs on XPSLCM1150 are
ON. Verify the external Mute active light(s) are ON and the XPSLCM1150 OSSD
outputs are in the RUN mode, XPSLCM1150 Display indicates 02 (mute active)
5 Interrupt the safety light curtain (SLC) with the correct test object. Verify that the
SLC outputs switch OFF (Red or blocked). OSSD inputs for that SLC are OFF,
XPSLCM1150 outputs remain ON. XPSLCM1150 Display indicates 02 (mute
active)
6 With the test object present in the light curtain sensing field, verify the machine
is "run capable". Remove the test object for further tests.
7 If the Mute Time Limit is enabled, maintain the mute state for 2 minutes. After 2
minutes the XPSLCM1150 OSSD outputs will switch from RUN to STOP. The
external Mute Active light will flash at a 1-2 Hz rate and the display will indicate
03 (Bypass Allowed). Press the Start switch and verify the XPSLCM1150
outputs return to the RUN state and external Mute Active lamp is ON.
XPSLCM1150 Display indicates 02. Bypass is allowed until either the muting
sensors clear or light curtain clears or 10 minutes has expired.
8 Reset system to Normal (non-mute) Operation.
9 If a one way or directional system is used, test operation to verify mute is
activated only when the correct sequence and intervals are applied and that the
machine (in the case of a machine tool such as a power press) is muted only
during the non-hozardous cycle.
10 Repeat test procedure(s) for 2nd muting channel (if installed).

Glossary
A
Automatic Start Upon completion of power-up, the XPSLCM1150 will enter the MACHINE RUN state
as soon as all of the selected light curtain OSSD inputs are in the ON state.
Schneider has traditionally referred to this as the Normal mode.
B
Bypass-Allowed Allows supervisor personnel to momentarily override the Machine Stop operation of
the XPSLCM1150. This function is used during instances where processing
sequence operations did not allow a transition to the Muting state and the
XPSLCM1150 entered the Machine Stop state. When in the Bypass-Allowed state,
a press-and-release of the Start button allows the XPSLCM1150 to transition to the
Muting state for only one cycle or a maximum duration of 10 minutes.
D
Dark-On A photo-electric sensor term that means the sensor output will be active when the
sensor detects an object.

E
EDM/MPCE
(Machine
Primary Control
Element)
Monitoring
The XPSLCM1150 monitors the state of the EDM/MPCE signal produced by the
guarded machine to insure that it is in the correct state with respect to "Machine
Run" and "Machine Stop."
I
Interlock For the XPSLCM1150 to enter this state the unit must be set to either the Start
Interlock or Start/Restart Interlock mode. In this state the yellow Interlock LED is on
and the red Machine Stop LED is on.
L
Light-On A photo-electric sensor term that means the sensor output will be active when it
receives the sensed light source.
Lockout (Fault) When the XPSLCM1150 detects a fault, it transitions to this state. The Safety
outputs will be held to the off state and the XPSLCM1150 will not attempt to leave
this state without performing a comprehensive power-up self-test. A power-up selftest will be initiated by either cycling the XPSLCM1150 power or by a Start signal
transition.
M
Machine Run When the XPSLCM1150 is in this state the two Safety outputs are both active. In this
state, the Green Machine Run LED is on, the Red Machine Stop LED is off and the
Yellow Interlock LED is off.
Machine Stop When the XPSLCM1150 is in this state the two Safety outputs are both inactive. In
this state the Green Machine Run LED is off, the Red Machine Stop LED is on and
the Yellow Interlock LED is off.

Glossary
Muting The mute sensors have been properly activated for the XPSLCM1150 to keep the
Safety outputs active when the light curtain detection zone is interrupted.
O
OFF State The state in which the output circuit is interrupted and does not permit the flow of
current.
ON State The state in which the output circuit is completed and permits the flow of current.
R
Response Time The maximum amount of time required for the XPSLCM1150 to recognize a light
curtain detection zone interruption and to set its Safety outputs to the Off state.

Start/Restart
Interlock
08/2007 63
The component of the XPSLCM1150 connected to the control system of the
guarded machine.
Start signal transition must occur before going to Machine Run for the first time.
Once the first Start condition has been met, the XPSLCM1150 will operate in the
Automatic Start mode.
The XPSLCM1150 will go into the Interlock state upon completion of power-up and
after all light curtain detection zone interruptions which cause a transition to the
Machine Stop state. A Start signal transition must occur before returning to Machine
Run following any transition to Machine Stop.
