SI-RF Overview
Use the SI-RF Radio Frequency Safety Switch to monitor the position of a guard to detect its movement, opening, or
removal. A "guard" can be a gate, door, cover, panel, barrier or other physical means that separates an individual from a
hazard. Safety switches will issue a signal to the machine control system to prevent or stop (halt) hazardous situations when
the guard is not in the proper position. The SI-RF Safety Switch is designed for non-locking guarding applications, unless
another means of locking is provided.
The SI-RF Safety Switch is considered a Type 4 interlocking device per ISO 14119 that are actuated by an electronic field
interacting with the coded actuator typically mounted on the guard. Different levels of coded sensors are available: low, high,
and unique.
Applications involving the use of the SI-RF Safety Switch should take into consideration the following standards:
• ISO 13849-1/2 - Safety of Machinery - Safety Related Parts of Control Systems
• ISO 12100 - Safety of Machinery - Risk Assessment and Risk Reduction
• ISO 14119 - Safety of Machinery - Interlocking Devices Associated with Guards
• ANSI B11.0 - Safety of Machinery - General Requirements and Risk Assessment

• ANSI B11.19 - Performance Criteria for Safeguarding
The SI-RF Safety Switch can be used individually or in series. A series string can consist of 1 to 32 units. The redundant
safety inputs are only used for the serial connection of sensors (for an individual unit or last in the string they get tied to +24 V
dc). The redundant safety outputs can be used for serial connection of sensors or for the connection to the safety-related
parts of the control system.

Configuration Instructions
Safety Code for Operation
The actuator of the SI-RF Safety Switch system has a non-modifiable safety code for distinct and error-free identification.
This code must be submitted to the SI-RF Safety Switch and permanently saved in the SI-RF Safety Switch. Three different
coding levels are available:
• Low (L)—The SI-RF Safety Switch accepts any actuator.
• High (H)—The SI-RF Safety Switch only accepts the last taught-in actuator, a maximum of 12 teach-in processes are
possible.
• Unique (U)—The SI-RF Safety Switch only accepts the taught-in actuator, and only one teach-in process is possible.
Teach the Safety Code
1. Position the new actuator in front of the SI-RF Safety Switch.
2. Energize the SI-RF Safety Switch for minimum 5 seconds.
The amber and green LED on the SI-RF Safety Switch flash with flash code 6 for 1.5 seconds (see "Status Indicators"
on page 31). The new actuator code is stored temporarily.
3. Disconnect the SI-RF Safety Switch from supply voltage.
4. With the new actuator still positioned in front of the SI-RF Safety Switch, again energize the switch for a minimum of 5
seconds.
The amber and the green LED on the SI-RF Safety Switch flash with flash code 6 for 3 seconds. The new actuator
code is saved in the SI-RF Safety Switch.
If a different actuator code is read on the second power-up, the temporarily stored code is lost and you must re-start the
process.
NOTE: If, after this process is followed, the Amber LED is still flashing BC1, disconnect the output wires. If
the Amber LED turns on solid, the outputs could be shorted to a voltage source.

Installation Instructions
Installation Requirements
The following general requirements and considerations apply to the installation of interlocked gates and guards for the
purpose of safeguarding. In addition, the user must refer to the relevant regulations and comply with all necessary
requirements. See ANSI B11.19, or ISO 14119 and ISO 14120, or the appropriate standard.
Hazards guarded by the interlocked guard must be prevented from operating until the guard is closed; a stop command must
be issued to the guarded machine if the guard opens while the hazard is present. Closing the guard must not, by itself, initiate
hazardous motion; a separate procedure must be required to initiate the motion.
Locate the guard an adequate distance from the danger zone (so the hazard has time to stop before the guard is opened
sufficiently to provide access to the hazard). Guard locking or supplemental safeguarding must be used if the overall stopping
time of the machine or the time to remove the hazard is greater than the time to access the guarded area. The guard must
open either laterally or away from the hazard, not into the safeguarded area. The guard also should not be able to close by
itself and activate the interlocking circuitry. The installation must prevent personnel from reaching over, under, around or
through the guard to access the hazard. Any openings due to positioning, movement, or misalignment in the guard must not
allow access to the hazard—see ANSI B11.19, ISO 13855, ISO 13857, or the appropriate standard.
The guard must be strong enough and designed to protect personnel and contain hazards within the guarded area that can
be ejected, dropped, or emitted by the machine. Mount the SI-RF Safety Switch securely so that the physical position cannot
shift, using reliable fasteners that require a tool to remove. Mounting slots in the housing, if provided, are for initial adjustment
only; final mounting holes (round) must be used for permanent location. The switches, actuating systems, and actuators must
not be used as a mechanical or end-of-travel stop.
When the guard is closed, the actuator is guided to the sensor. When the switch on distance is reached, the sensor detects
the actuator code. If the sensor detects an acceptable code it turns the output signal switch device (OSSD) safety outputs
(OSSD1 and OSSD2) ON. When the guard is opened, the actuator is removed from the response range of the sensor. The
sensor switches the safety outputs (OSSD1 and OSSD2) OFF.
See " Mechanical Installation " on page 11, " Electrical Installation " on page 14, Switching Diagrams, and "SI-RF
Specifications " on page 23 for additional information.
Design and install the safety switches and actuators so that they cannot be easily defeated. Measures to minimize defeat
(bypassing) of interlocking safety switches include:
• Minimizing motivation for defeating interlocking by providing training, supervision, and efficient means for machine
setup/adjustment, operation and maintenance
• Limiting accessibility to the interlocking device, such as mounting out of reach, mounting behind a physical
obstruction, mounting in a concealed position
• Preventing the switch or the actuator from being disassembled or repositioned that compromises the safety function.
(for example, welding, one-way screws, riveting)
• Using hardware that requires a tool to remove that is not readily available.

SI-RF Non-Contact RF Safety Switch Instruction Manual
WARNING:
• Properly Install the Interlocked Guards
• Failure to follow these guidelines could result in serious injury or death.
• At a minimum, the interlocked guard must prevent hazards when not fully closed and must prevent
access to the hazards through any opening in the guard.
• Install the safety switches and actuators so they cannot be easily defeated and are not used as a
mechanical or end-of-travel stop.
• The user must refer to the relevant regulations and comply with all necessary requirements. See
ANSI B11.19, or ISO 14119 and ISO 14120, or the appropriate standard.
CAUTION:
• Do not use the safety switch as a mechanical or end-of-travel stop.
• Catastrophic damage can cause the safety switch to fail in an unsafe manner (that is, loss of the
switching action).
• Limit the movement or rotation of the guard to prevent damage to the safety switch or the
actuator.
WARNING:
• The hazard must be accessible only through the sensing field
• Incorrect system installation could result in serious injury or death.
• The installation of the SI-RF Safety Switch must prevent any individual from reaching around,
under, over or through the defined area and into the hazard without being detected.
• See OSHA CFR 1910.217, ANSI B11.19, and/or ISO 14119, ISO 14120 and ISO 13857 for
information on determining safety distances and safe opening sizes for your guarding device.
Mechanical barriers (for example, hard (fixed) guarding) or supplemental safeguarding might be
required to comply with these requirements.
Pass-Through Hazards and Perimeter Guarding
A pass-through hazard is associated with applications where personnel may pass through a safeguard (which issues a stop
command to remove the hazard), and then continues into the guarded area, such as in perimeter guarding. Subsequently,
their presence is no longer detected, and the related danger becomes the unexpected start or restart of the machine while
personnel are within the guarded area.
Eliminate or reduce pass-through hazards whenever possible—see ANSI B11.19 and ANSI B11.20 or ISO 11161. One
method to mitigate the risk is to ensure that once tripped, either the safeguarding device, the safety related part of the control
system, or the guarded machine's MSCs/MPCEs will latch in an OFF condition. The latch must require a deliberate manual
action to reset that is separate from the normal means of machine cycle initiation.
This method relies upon the location of the reset switch as well as safe work practices and procedures to prevent an
unexpected start or restart of the guarded machine. All reset switches must be:
• Outside the guarded area
• Located to allow the switch operator a full, unobstructed view of the entire guarded area while the reset is performed
• Out of reach from within the guarded area
• Protected against unauthorized or inadvertent operation (such as through the use of rings or guards)
If any areas within the guarded area are not visible from the reset switch, additional safeguarding must be provided.

WARNING:
• Perimeter guarding applications
• Failure to observe this warning could result in serious injury or death.
• Use lockout/tagout procedures per ANSI Z244.1, or use additional safeguarding as described by
ANSI B11.19 safety requirements or other applicable standards if a passthrough hazard cannot be
eliminated or reduced to an acceptable level of risk.
Mechanical Installation
IMPORTANT: Install a safety switch in a manner that discourages tampering or defeat. Mount switches to
prevent bypassing of the switching function at the terminal chamber or Quick Disconnect (QD). A switch
and its actuator must never be used as a mechanical stop. Overtravel may cause damage to switch.
All mounting hardware is supplied by the user. Fasteners must be of sufficient strength to guard against breakage. Use of
permanent fasteners or locking hardware is recommended to prevent the loosening or displacement of the actuator and the
switch body. The mounting holes (4.5 mm) in the switch and actuator body accept M4 (#6) hardware.
Mount the sensor and actuator such that the position cannot be changed after installation/adjustment. Mount the switch
securely on a solid, stationary surface. Prevent the loosening of mounting hardware by using lock washers, thread-locking
compounds, etc. Only use slots for initial positioning. Pins, dowels, and splines can be used to prevent movement of the
switch and the actuator.
Install the SI-RF Safety Switch to prevent false or unintended actuation and intentional defeat.
Locate the sensor and actuator to allow access for functional checks, maintenance, and service or replacement. The
installation should provide suitable clearances, be readily accessible, and allow access to the actuator and sensor.
CAUTION:
• Overtightening the units during installation can twist the housing and affect the sensor's
performance.
• Do not overtighten the units during installation.
IMPORTANT: It is the responsibility of the machine builder (user) to make sure the series wiring/cabling is
not easily manipulated by an operator to defeat the safety function(s); for example, cannot remove a
switch from the chain.

Within the detection range, there are "side lobes", in which the sensor can also activate. In an application with actuation
direction 3, maintain a minimum distance X ≥ 5 mm between the SI-RF Safety Switch and actuator to ensure there is no
activation within the side lobes.
The specified sensing distances can only be reached if the following conditions are met:
• Do not install the sensors near magnets or strong magnetic fields.
• Do not flush mount the sensor and actuator to metallic materials. Metal can influence the sensing distances.
IMPORTANT: When multiple units are mounted next to each other, there must be a minimum 100 mm
distance between each sensor to ensure trouble-free operation.
IMPORTANT: If two actuators are used to activate one sensor, the actuators must have a separation
distance of at least 20 mm (measured from the side of the housings).

Only authorized personnel should install these devices. Any of the shown mounting positions and approach directions may be
used. Install the SI-RF Safety Switch so that the display is visible. The triangular symbols serve for the alignment and should
point to each other.
Immediately replace any damaged SI-RF Safety Switch or actuator components. They can be replaced separately, with the
exception of the Unique (U) coded version. If you are using the Unique (U) coded version, the SI-RF Safety Switch and
actuator must always be replaced together.
Resetting the Inputs
The reset function forces a local confirmation that the safety outputs are switched on after closing the movable safety guard.
If the moveable guard is opened using a sensor with a reset function, close and open the reset button within 0.25 seconds
(minimum) to 1 second (maximum), after the guard has been closed.
The reset function only applies to the sensor with the reset functionality. This reset feature allows for a local reset at a given
guard but does not allow for an entire safety system reset. If a chain of sensors is cascaded (see "Wire the Switch in Series "
on page 18), the reset function only applies to SI-RF 3. If SI-RF 1 or 2 are opened then closed, the outputs will switch on after
the guard is closed, without actuating the reset button.
CAUTION:
• When power is switched on and the guard is in the closed position, the safety outputs switch on
without actuating the reset button.
• Automatic reset at power-up must be addressed in the customer's controls.
WARNING:
• Use of Auto or Manual Restart
• Failure to follow these instructions could result in serious injury or death.
• Application of power to the Banner device, the closing of the movable safety guard, or the reset of
a manual restart condition MUST NOT initiate dangerous machine motion. Design the machine
control circuitry so that one or more initiation devices must be engaged (in a conscious act) to start
the machine - in addition to the Banner device going into Run mode.

SI-RF Non-Contact RF Safety Switch Instruction Manual
Auxiliary Output/Information
The PNP output models (SI-RFS and SI-RFP) have a diagnostic PNP output. The PNP Diagnostic is not safety-related.
The PNP Diagnostic output indicates whether the right actuator has been detected (for example, the door is closed).
• Output high (conducting) - Actuator not detected
• Output low (open or non-conducting) - Actuator detected
When the SI-RFS sensors are cascaded, the output only signifies the actuator status of its sensor, not the others in the string.
With manual reset models (SI-RFSL), the auxiliary output changes back to the low state when the actuator is sensed (does
not wait for the reset).
Note that the switching point of the auxiliary output might not match the switching point of the safety outputs.
The ISD models (SI-RFD) do not have an auxiliary output.
In-Series Diagnostic Information
The information transmitted via the In-Series Diagnostic (ISD) interface is not safety-related. The diagnostic technology
allows a wide range of sensor information to be loaded into the machine control system.
To interpret the information, Banner diagnostic modules are available, including the SI-RF-DM1 and -DM2 Diagnostic
Modules and the SC10-2roe or XS26-ISDx Safety Controller. Refer to the instruction manuals for detailed information on the
diagnostic devices. By means of diagnostics, the following information can be transmitted, among others:
• Door status (open, closed, or faulted)
• Detection of misalignment (marginal signal strength of RF field)
• Detection of under-voltages in the series connection
• Attempts to defeat an RF gate switch
For a complete list of the diagnostics information, see "Information Available via ISD" on page 32.
At this time this information can be refined via the following interfaces:
• USB—display of the sensor information on the PC (requires using an SI-RF-DM1 Diagnostic Module or
an SC10-2roe or XS26-ISDx Safety Controller)
• IO-Link—bus independent data reading into the control system (requires using the SI-RF-DM1 or SI-RFDM2 Diagnostic Modules and an IO-Link master)
• Industrial Ethernet Protocols—Bus data reading into the control system (requires using the SC10-2roe or XS26ISDx Safety Controller)
Electrical Installation
WARNING:
• Risk of electric shock
• Use extreme caution to avoid electrical shock. Serious injury or death could result.
• Always disconnect power from the safety system (for example, device, module, interfacing, etc.),
guarded machine, and/or the machine being controlled before making any connections or
replacing any component. Lockout/tagout procedures might be required. Refer to OSHA
29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy.
• Make no more connections to the device or system than are described in this manual. Electrical
installation and wiring must be made by a Qualified Person(1) and must comply with the applicable
(1) A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training and experience, has
successfully demonstrated the ability to solve problems relating to the subject matter and work.

electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or
IEC 60204-1, and all applicable local standards and codes.
Protective Stop (Safety Stop) Circuits
A protective stop (safety stop) allows for an orderly cessation of motion for safeguarding purposes, which results in a stop of
motion and removal of power from the Machine Primary Control Elements (MPCE) (assuming this does not create additional
hazards).
A protective stop circuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically
linked relays, which are monitored through External Device Monitoring (EDM) to detect certain failures, to prevent the loss of
the safety function. Such a circuit can be described as a "safe switching point".
Typically, protective stop circuits are either single channel, which is a series connection of at least two normally open
contacts; or dual-channel, which is a separate connection of two normally open contacts. In either method, the safety function
relies on the use of redundant contacts to control a single hazard. If one contact fails ON, the second contact arrests the
hazards and prevents the next cycle from occurring.
The interfacing of the protective stop circuits must be accomplished so that the safety function cannot be suspended,
overridden, or defeated, unless accomplished in a manner of the same or greater degree of safety as the machine's safety
related control system that includes the SI-RF Safety Switch.
A Banner XS26-2 Safety Controller with XS1ro or XS2ro Relay Expansion Module, Banner SC10-2roe Safety Controller, or
Banner UM-FA-xA Universal Safety Module provides a series connection of redundant contacts that form protective stop
circuits for use in either single-channel or dual-channel control.
Output Signal Switching Devices (OSSDs) and External Device Monitoring
(EDM)
The SI-RF Safety Switch is able to detect faults on OSSD1 and OSSD2. These faults include short circuits to +24 V dc and 0
V, and between OSSD1 and OSSD2.
Both OSSD outputs must be connected to the machine control so that the machine's safety-related control system interrupts
the circuit or power to the machine primary control element(s) (MPCE), resulting in a non-hazardous condition.
Final switching devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.
Refer to the output specifications and these warnings before making OSSD output connections and interfacing the SI-RF
Safety Switch to the machine.
WARNING:
• Interfacing both output signal switching devices (OSSD)
• Failure to follow these instructions could result in serious injury or death.
• Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES,
PC) between the safety module outputs and the master stop control element it switches such that
a failure causes a loss of the safety stop command or the failure allows the safety function to be
suspended, overridden, or defeated.
• Connect both OSSD outputs to the machine control so that the machine’s safety-related control
system interrupts the circuit to the machine primary control element(s), resulting in a nonhazardous condition.

SI-RF Non-Contact RF Safety Switch Instruction Manual
WARNING:
• OSSD Interfacing
• Failure to properly interface the OSSD Outputs to the guarded machine could result in serious
injury or death.
• To ensure proper operation, the Banner device output parameters and machine input parameters
must be considered when interfacing the Banner device OSSD outputs to machine inputs.
Machine control circuitry must be designed so that the maximum load resistance value is not
exceeded and that the maximum specified OSSD Off-state voltage does not result in an On
condition.
External device monitoring (EDM) is a function used to monitor the state of the external, positively guided (mechanically
linked) machine control contacts (Final Switching Devives (FSD) and/or MPCEs). The SI-RF Safety Switch does not include
the EDM function. As a result, the SI-RF Safety Switch should be used with an external safety monitoring device that
monitors the status of the two SI-RF Safety Switch OSSDs and is capable of providing the EDM function.
Examples of appropriate external safety monitoring devices include Banner SC10-2roe, SC26-2, and XS26-2 Safety
Controllers; Banner UM-FA-9A and UM-FA-11A Universal Input Safety Modules; and Safety PLCs.
WARNING:
• The SI-RF Safety Switch does not have external device monitoring (EDM).
• If EDM is required for the application, it must be implemented in the external control.
Fault-Tolerant Output Feature
Faults that do not immediately compromise the safe operation of the SI-RF Safety Switch (for example safety output to
external potential, crosswire short safety output) result in a delayed switch-off of the safety outputs.
The safety outputs switch off when the error warning exceeds 20 minutes. In case of error warning, the red LED flashes code
BC2.
Use this fault-tolerant output feature to run down the machinery in a controlled manner. After fixing the fault, the error
message is confirmed by a voltage reset. The safe outputs enable and allow a restart.
Wiring for Single PNP (SI-RFP)
Five-conductor, cannot be wired in series
A movable safety guard is monitored through one SI-RF Safety Switch. The safety outputs of the SI-RF Safety Switch are
connected to a safety monitoring module. When the safety guard is closed (actuator detected), the SI-RF Safety
Switch switches on its safety outputs.
When being used individually, the SI-RFP series offers a simple 5-pin wiring scheme. Use the optional PNP auxiliary output
to transfer non-safety related status information.

Feedback Loop (optional)
Wire the Switch in Series
To monitor several movable safety guards with a series connection of SI-RF Safety Switch, follow these steps.
1. Connect the safety outputs of the last SI-RF Safety Switch to a safety monitoring unit.
2. Connect the safety inputs of the first SI-RF Safety Switch of the series to + 24 V DC.
3. Connect the safety outputs of the first SI-RF Safety Switch to the safety inputs of the second SI-RF Safety
Switch (and second to third, etc).
4. When all the safety guards are closed (all actuators are detected), the last SI-RF Safety Switch of the series
connection switches on its safety outputs.
5. If you are using an optional In-Series Diagnostic (ISD) device (SI-RFD series), integrate the diagnostic device
between the last SI-RF Safety Switch and the safety monitoring module in the series connection. The status
information can then be retrieved from the diagnostic device.
NOTE: Verify the SI-RF Safety Switch and the safety monitoring module are powered from the same
power supply or the commons of the separate supplies are the same.
If you are using the optional PNP auxiliary output (SI-RFS series), only the non-safety-related status information of each
individual sensor can be obtained.
After the door is closed, the optional reset function requires a manual acknowledgment before the safety output of the sensor
is switched on (only that individual sensor, not the series string).

SI-RF Non-Contact RF Safety Switch Instruction Manual
Wire the Switch in Series Using the Quick Disconnect
Use models SI-RFS and SI-RFD for this configuration.
When connecting units in series, simplify the wiring using special t-adapters and low-cost unshielded four-wire double-ended
cables. A similar configuration is shown except the connections are all made using quick disconnects. The SSAEB1PLx-0Dx E-stops, SI-RFD switches, and the SSA-ISD Connect can be combined in a single chain.
1. Connect the female 4-pin M12 cable to the male 4-pin M12 of the series connection t-adapter (SI-RFA-TS).
2. If a manual reset model sensor is used, connect the female 8-pin M12 of the Reset T-Adapter (SI-RFA-TK) to the
male 8-pin M12 connector of the series connection t-adapter. Connect a female 4-pin M12 cable to the male 4-pin
M12 QD of the t-adapter for connecting a reset switch or reading the Auxiliary output.
3. Connect the sensor to the male 8-pin M12 connector of the t-adapter.
4. Connect the male 4-pin M12 end of a double-ended cable to the female 4-pin M12 of the t-adapter. Connect the
female 4-pin M12 end of the double-ended cable to the next series connection t-adapter (SI-RFA-TS).
5. At the end of the line a terminating plug (SI-RFA-P) is required to properly truncate the system.
6. The wired end of the 4-pin M12 cable (from step 1) can be wired directly to a Safety Monitoring Module or can be
wired through an In-Series Diagnostic (ISD) module then to the Safety Monitoring device.
Verify that the SI-RF Safety Switch and the safety monitoring module are powered from the same power supply or the
commons of the separate supplies are the same. Ensure that the voltage level at SI-RF 1 (furthest from the power supply) is
above 19.5 V for the system to operate properly.

In long chains, or chains with a lot of ISD devices, the voltage at the first device (device closest to terminating plug) must stay
above 19.5 V for the chain to operate properly.
For guidance on the maximum total cable length and a maximum number of devices before an additional power supply may
be needed, refer to "Maximum total cable length for a single power supply" on page 20. For using ISD information to monitor
the individual device voltages, see "In-Series Diagnostic Information " on page 14.
An additional power supply may be required to maintain a minimum of 19.5 V at all devices. There are two options to connect
an additional power supply.

The SI-RFD switches and the ISD Connect have similar current demands. However, when used with a number of lighted ISD
emergency stop devices, the current draw of the emergency stop devices governs the cable lengths and when more power is
needed. The maximum cable length between devices (including the last unit and the ISD evaluation device) is 30 meters.
