1. INTRODUCTION
The TAPESWITCH Safety Edge sensor is a pressure-sensitive safety device designed to protect operators
working at or near dangerous machinery. The switch functions as a momentary-contact, normally-open switch
which electrically closes when force is applied in the normal direction to the edge sensor.
Multiple safety edge sensors may be wired, in series, to form a larger sensing area. In a sensing edge safety
configuration, a small electrical signal flows through (from the safety interface controller - SIM) the upper and
lower conductors of the insert switch element(s) at all times. This signal is used by the safety interface
controller/safety interface module (SIM) to continuously monitor safety integrity.
When an appropriate (force distance relationship for all edge sensors in this manual) actuating force is applied to
the active area of the edge sensor, the internal ribbon switch closes (from open circuit to closed circuit), which, in
turn, causes an appropriate SIM to recognize this condition and thus initiate a stop command to the prime motion.
If any of the connecting wiring, internal or external to the safety edge sensor should break or separates (using an
appropriate SIM), this is also detected by the controller and, in turn, causes the SIM to recognize this condition
and thus initiate a stop command to the prime motion and should not attempt to begin running until the fault
condition is fully accessed , repaired and tested. thus, the machine cannot run unless there is integrity throughout
the safety configuration.
When correctly installed and interfaced to a machine (through a SIM), the safety edge configuration can initiate a
stop command to the machine primary control element (MPCE), and/or parts of the machine chosen by the
designer.
NOTE
Tapeswitch safety edge sensors, individually or wired together, do not by themselves constitute
a complete safety system. The user must also select a safety interface controller/safety interface
module (SIM) that complies with annex B of ISO 13849-1 (EN954-1) and the guidelines in ANSI
B11.19 as well as any and all updated local and federal requirements.
This controller must include dual channel monitoring such that a single electrical failure in the
edge sensors, interconnecting wiring, or the control unit itself will be detected and will shut
down the machine.
This will establish a complete safety machine interface system. In addition, the category rating
will then be at the level of the attached controller to a maximum category level of 3.

2. PACKAGING, HANDLING, TRANSPORTATION, AND STORAGE
2.1 Packaging, Unpacking, and Handling
Depending on the size and weight, safety edges are packaged either in a "U" formed cardboard container or
wooden frame container with a triple-wall cardboard top and bottom, or in a suitable corrugated box. Multiple
edges may be stacked in a single box. Unpacking may require more than one person. Keep the edges flat at all
times. DO NOT ROLL, COIL OR FOLD THEM. DO NOT LIFT OR PULL edge sensor(s) BY THE CABLES.
Failure to follow these instructions could render the edge sensors unusable.
2.2 Transportation
When shipping an edge or edges, use the original or similar packaging to prevent damage. Crates can be
transported by common carrier or parcel service (size permitting). The crate should be kept flat and should not be
transported on its side or vertically for an extended period of time.
2.3 Storage
The edges sensors should be stored in a horizontal (flat) position. Do not stack or pile a heavy load on top of the
edge sensors as this could lead to switch damage and premature failure. The edge sensors should be stored in a
dry environment at a temperature of 0°C to 50°C.

4. TECHNICAL DESCRIPTION
4.1 System Overview
Safety edge sensors are used to create a sensing area that may consist of a single edge or a combination of
edges. When the sensing edge is compressed to actuation, the (electrically closed) condition is detected by the
safety interface module (SIM). When appropriately configured, the (SIM) switches off its output relays and/or PNP
drivers, ideally causing dangerous motion to cease or be prevented.
4.2 Edge Sensor Design
4.2.1 Internal Construction
Each Tapeswitch sensing edge utilizes Controflex ribbon switch technology for its electrical switching
component. Each edge is designed to focus applied force (along the reference direction of the sensor) toward the
internal Controflex ribbon switch, thereby creating switch closure and supplying a signal to the SIM for evaluation
and "Stop" command.
4.2.2 Chemical Resistance
Tapeswitch safety edge sensors are constructed utilizing several material compounds. All materials are resistant
to chemicals commonly found in an industrial environment.
Please see the following table to determine the material best suited to your application. Upon request, Tapeswitch
can supply a small sample of edge material for your own chemical testing. Please contact
sales@tapeswitch.com with your request.
Chemical Resistance Table - Figure 3
4.2.3. Combining of Sensors
When multiple edge sensors are used in combination, they must be wired in series, such that the SIM monitors
the entire array as if it were one normally-open switch. Actuation of any sensing edge segment will result in a
signal transition at the SIM’s monitoring input.

4.2.3.1 Four-wire edge sensors (fail-safe)
For sensing edge configurations utilizing fail-safe wiring, one pair of leads can be considered to be the input and
the other pair the output. When connecting several edge sensors together, the output of the first edge sensor is
connected to the input of the second edge sensor, and so on. This leaves the input leads of the first edge sensor
and the output leads of the last edge sensor available for connection to the (PRSU/4 or PRSU/5) SIM as
illustrated below:

4.2.3.2 Two-wire edge sensors with end of line (EOL) resistor
Upon request, Tapeswitch offers all edge sensors in a two-wire (control reliable to meet safety performance level)
configuration. This configuration utilizes a single, two-wire cable at one end of the sensor and an appropriate EOL
resistor at the other. A suitable SIM (Tapeswitch PSSR/2) will provide a monitored system with safety outputs to
be interfaced to the machine control system as intended.
For applications that require an array of interconnected sensing edges and an end-of-line (EOL) resistor, all edge
sensor segments but the last must be of the 4-wire configuration. The last edge in the series must have the EOL
resistor at its output.
Note:
While utilizing the two-wire edge sensor with EOL resistor, the maximum resistance between actuator terminals
cannot exceed 8.7K ohms. This will render the sensing edge assembly incompatible with PSSR/2 model SIMs.
The complete manual for PSSR/2 can be found at the following link:

5. EDGE SENSOR SELECTION
5.1 General Considerations
5.2 Edge Sensor selection
There are a number of factors that must be addressed when selecting a sensing edge’s length, profile and
mounting channel. These include, but are not limited to:
(a) Safety standard and category/performance level required of system.
(b) Speed and stopping over-travel of a machine’s prime movement.
(c) Responsiveness of the supervising control system (time from actuation to inhibition of machine movement).
(d) Environmental conditions of process (temperature, chemical properties, spray/spatter profile).
(e) Proper training of persons associated with operation.
(f) Ability of the process to stop hazardous motion in a control reliable method according to determined SIL.
NOTE:
The guidelines described in this document must only be carried out by qualified personnel. Such
personnel must have the appropriate training and authorization regarding operation, maintenance and
modification to the electronic controls.
The machine control must be electrically actuated.
It must be possible to immediately stop any dangerous operation of the machine.
In particular, the machine stopping times must be known and, if necessary, measured.
The stop performance of the machine must additionally undergo validation during routine
maintenance by trained and competent personnel. Should an evaluation render results indicating
degradation of the stop function beyond acceptable ratings, the machine must be locked out until
serviced/repaired and restored to nominal conditions.
Verify that the temperature of the environment where the system is installed is compatible with the
temperature operating parameters indicated on the product label and/or in the technical data.

6. INSTALLATION
This technical manual should be read in full before any installation work is attempted.
6.1 General Information
The attention of the installer is drawn to the following general requirements for installation of a Tapeswitch
sensing edge system:
(a) The machine must be electrically controllable (machine power leveraged by internal/external signals).
(b) It must be possible to stop the dangerous motion of the machine at any point in its operation, in any operating
mode.
(c) The control system, as a whole, must be designed to provide the level of safety integrity determined by the risk
assessment.
(d) Steps must be taken to prevent access to the dangerous parts of the machine from any direction not covered
by the sensing edge. Such steps could include safety mats, light curtains, fixed or interlocking fences or
screens, additional.
(e) Steps must be taken to prevent a person from standing in the dangerous area without being protected. It may
be necessary to apply additional mechanical and/or electrical safety devices to cover any surfaces within the
dangerous area on which a person could stand, such as the base of the machine.
(f) All edge sensors must be mechanically affixed such that it cannot be easily moved or removed. Tamperproof
hardware is highly recommended to discourage any un-authorized manipulation of the edge sensor or
sensors.
(g) There are no user-serviceable parts and the edge should never be altered or modified from its original
construction. Doing so will render the sensing edge nonfunctioning and immediately void any standing
warranty.
(h) Great care should be taken when handling edge sensors. Never pick the edge sensor up by or drag it around
using the cables. Never bend or fold an edge sensor. Keep edge sensors flat whenever possible. Always
store edge sensors flat. Edge sensors longer than 1 meter, should be handled by more than one person.
(i) After installation to machine, the edge sensor and SIM must be commissioned in accordance with Section 7
of this manual.
(j) Any covers removed during installation must be replaced as soon as possible.
WARNING: The Tapeswitch safety edge sensor is designed to protect operators working at or near
dangerous machines. It can only perform that function if it is correctly installed and interfaced to a
suitable machine controller and/or Safety Interface Module (SIM).
It is the responsibility of the user to ensure that all persons involved in the installation of the
product have the knowledge, training and experience necessary, and that they are fully competent
with knowledge of all laws, rules, regulations and codes of practice pertaining to their task. This
includes familiarity with the safety documents referenced on the title page of this manual.

Note:
Since angle mount flanges do not cause internal interference with the edge sensor housing, hardware size is
application- driven and must be sized correctly to ensure the edge sensor remains securely mounted.
Flat and "C" channel mounting configuration - Figure 8
6.2.2.1 Rail-Style channel (TS-46)
Rail-style mounting channels are available in either flat, or angled configurations. TS-46 angle mount channels
are pre-mounted to the edge sensor prior to shipping. After mounting, the sensing edge housing and actuator
should at no point be removed from the channel unless a replacement is required. Mounting holes (1/4-20 or
similar) should be drilled roughly every 12" of sensor length for sufficient mechanical mounting strength.
Tapeswitch suggests using tamper-proof hardware to discourage any changes by an unauthorized party. Before
mounting the flat variant of the channel, simply slide the edge sensor out of the channel and drill holes along the
channel’s centerline. Once the channel is mounted, the edge sensor can be slid back in place.
TS-46 "AF" mounting - Figure 9 TS-46 "AA" mounting - Figure 10
Edges such as the TS-46 utilize a rail-style mounting technique. To aid in housing/actuator removal, any mild
soapy water can be used as a lubricant. Lubricant should be applied to the bottom of the housing. For rail-style
mounting visuals, reference Figures 9 and 10 above.

6.2.2.2 Snap-in style channel
Most of the time, snap-in channels may also be slid in as well. The snap-in technology facilitates the ease of
mounting the sensor to the channel without additional room needed on each end of the channel. Before
attempting to snap the housing and actuator into the channel, apply lubricant (mild soapy water) to
housing/channel and press housing back into channel. (See Figure 11 below).
Snap In mounting - Figure 11
When mounting the assembly in place, tuck any interconnecting wires from the sensor into the edge’s cavity.
Insert (optional) dowel pin in each end of the sensing edge to prevent sliding. See below:

6.2.3 Lead Wiring Options
Tapeswitch edge sensors are normally supplied with one of the following options:
a. (2) 2-conductor cables (see specific edge specifications for identification - may exit OE or EE) – Standard.
b. (1) 2-conductor cable (with appropriate EOL resistor on termination end).
c. (1) 4-conductor cable (special order) - see PRSU/4 or PRSU/5 manual for wire diagram.
Note:
NON – FAIL-SAFE edges are available upon request. These feature a single 2-conductor cable and are
unsuitable for any safety application. Please contact sales@tapeswitch.com for non-fail-safe sensor options.
Non-fail-safe edges can NOT be made FAIL-SAFE.
For applications where multiple edge sensors are required, the "EE" (lead exits each end) ordering code must be
specified. This ensures that multiple edges can be connected by daisy-chain since both head and tail connections
are provided. If an “EOL” resistor is warranted, such as in systems employing a PSSR/2, the final edge in the
daisy-chain will only have a single 2-conductor cable, with an internal end-of-line resistor terminating the entire
assembly.
Tapeswitch safety edge sensors are manufactured with the following types of cable configurations:
a) Two – 2-conductor cable (four termination points) utilizing one of the following configurations below:
PRSU/5 and PSRU/4 connection - Figure 13
i) Two sets of BLACK/WHITE wires
Or:
ii) Two sets of black, ribbed/smooth zip-cord wires (one conductor has a ribbed jacked,
one conductor has a smooth jacket).

6.2.4 Installation Procedure and considerations:
Step 1 - Secure mounting channel of edge sensor onto your chosen surface. Each of the
Tapeswitch edge sensors are available with a variety of options (must be defined at the time of
purchase).
Note: It is imperative that edge sensors be affixed in such a way as to make it impossible
for someone, other than an authorized maintenance person, to adjust or remove. It is
recommended that the installers use tamper-proof hardware to discourage any
manipulation of the sensor. For multi edge configurations, sensors must be used in series
to maintain safety reliability.
Step 2 - If the sensor was removed from the channel for mounting, replace edge sensor now.
Edge sensors can be easily replaced (into its channel) by using the techniques described in
manual above.
Note: If the edge was mounted without removing from the channel, please skip to Step 3.
Step 3 - Route the cable(s) to the control unit. The cable(s) should exit from the edging as close
to the control unit position as possible. The cables should be protected in suitable conduit
between the exit of the edge sensor and the control unit. It is the installer’s responsibility to be
sure all cables are secured and protected from damage during normal use and meets all local
electrical codes.
7. COMMISSIONING CHECKS
The commissioning checks should be carried out by trained competent personnel who have
access to all the information supplied with the machine and its safety equipment and
requirements. The results of the examination should be recorded and the user and the employer
of the person performing the examination should keep copies of this record.
The person carrying out the examination should, as a minimum, perform the following checks:
a. Verify that the edge sensor is suitable for use in the application.
i.) Check that the level of safety integrity provided by the edge sensor is suitable for the
level of risk presented by the machine operation.
ii.) Check that the environment is suitable for the use of the edge sensor.
b. Check that the dimensions and position of the edge sensor are correct, taking into account
the operating mode. For this purpose, it will be necessary to check the overall system
response time using a device designed for this purpose.
c. Check that adequate measures have been taken to prevent access to the dangerous parts of
the machine from any direction not covered by the edge sensor.
d. Examine the machine controls and interconnection wiring to the sensing edge(s) and SIM
and ensure that all connections are correctly and securely made.
e. Check that the sensing edge is fixed in position and that no trip hazards are present within
the dangerous area.
f. Check that it is not possible for the dangerous parts of the machine to be set in motion while
the edge sensor(s) is actuated.

g. Check that actuation of the sensing edge, during a dangerous phase of operation (of the
machine), results in the dangerous motion(s) being arrested, or where appropriate, assuming
an otherwise safe condition, before any part of a person could reach them.
h. Check that after a machine has been stopped by the actuation of the edge sensor(s), it is not
possible for the dangerous parts to be set in motion until the edge sensor has been cleared, a
reset switch has been operated and released, and the machine start control has been re-
actuated.
i. Check that the removal of power from the edge sensor or the connected SIM prevents further
operation of the machine. It should not be possible for the dangerous parts of the machine to
be set in motion until power has been restored, the reset switch has been actuated (if utilized)
and released, and the machine start control has been actuated.
j. Check that the edge sensor operates over the whole active area by actuating the sensor,
along its surface, normal to the direction of motion.
k. Examine the stopping performance monitor (if installed) to ensure that it is installed and
functioning correctly. Ensure that the means by which the stopping performance can be
assessed by the operator is indicating correctly.
l. Test the muting arrangements (if installed). Ensure that the muting is only possible during
non-dangerous operation and ensure that the safety level of the muting device is at or above
that of the safety mat but never below.
m. Examine brakes and clutches (if installed) as recommended.
8. CLEANING AND MAINTENANCE
Once installed and interfaced (SIM) to a machine, the edge sensor(s) will be an active safety
sensor. It will actuate each time an appropriate force is applied in the active direction of the
sensor.
The edge sensor(s) does not require any periodic maintenance; however, its life will be
considerably increased if a basic cleaning routine is performed.
The frequency of general cleaning depends on the nature of the environment. In relatively clean
environments, where the edge sensor(s) is rarely exposed to water or other fluids, monthly
cleaning is usually sufficient. In dirtier environments, clean weekly or more frequently, as
required.
IMPORTANT after any part of the system has been replaced, the installation should be
considered as new and, as such, should be re-commissioned in accordance with this manual.
The edge sensors have no user repairable parts. Contact Tapeswitch Corporation at 1-800-234-
8273 for replacements.
WARNING: Servicing of edge sensors or SIM's should only be carried out
by qualified personnel. Servicing involves the exposure of terminals and devices
that carry potentially lethal voltages. Only those persons, with the appropriate
training and experience, should undertake this work. If there are any questions
call Tapeswitch Corporation at 1-800-234-8273.
