Important Information Regarding the Use of Safety Switches
In the United States, the functions that Banner safety switches are intended to perform are regulated by the Occupational Safety and Health
Administration (OSHA). Whether or not any particular safety switch installation meets all applicable OSHA requirements depends upon factors
that are beyond the control of Banner Engineering Corp. These factors include the details of how the safety switches are applied, installed, wired,
operated, and maintained.
Banner Engineering Corp. has attempted to provide complete application, installation, operation, and maintenance instructions. This information is
found in the instruction manual packaged with each safety switch. In addition, we suggest that any questions regarding the use or installation of
safety switches be directed to the factory applications department at the telephone numbers or address shown below.
Banner Engineering Corp. recommends that safety switches be applied according to the guidelines set forth in international (ISO/IEC) standards
listed below. Specifically, Banner Engineering Corp. recommends application of these safety switches in a configuration which meets safety
category 4, per ISO 13849 (EN954-1).
In addition, the user of Banner safety switches has the responsibility to ensure that all local, state, and national laws, rules, codes, and regulations
relating to the use of Banner safety switches in any particular application are satisfied. Extreme care is urged that all legal requirements have been
met and that all installations and maintenance instructions are followed.

Easy Access
The wiring chamber is accessed via a hinged door. Simply insert a flat-blade screwdriver,
as shown, and pry gently down to open.
Rotating Actuator Head
The actuator head may be rotated in 90° increments to create eight possible actuator
engagement locations. To rotate the head, pull the holding clamp forward, rotate the
head to the desired position, and push the holding clamp back in to lock.
Mechanical Installation
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 loosening or displacement of the actuator and the switch
body. The mounting holes in the switch body and the actuator accept M5 screws (see
dimensions, page 7).
Position the switch, with its actuator fully engaged, in the mounting location and mark the
mounting holes. Drill the required holes and fasten the switch body and the actuator in
place. After the mounting hardware is secure, check the actuator-switch engagement for
misalignment and binding.
IMPORTANT
1. A safety switch must be installed in a manner which discouranges tampering or
defeat. Mount each switch to prevent bypassing of the switching function at the
terminal chamber.
2. A switch and its actuator must never be used as a mechanical stop.

Electrical Installation
Access to the Wiring Chamber
The wiring chamber is accessed via the hinged door. See Figure 1. The SI-LS83
switches have a wire entrance of M16 x 1.5. The SI-LS100 models have a wire entrance
of M20 x 1.5. All models come with an adaptor to convert to 1/2"–14 NPT. M16 x 1.5 and
M20 x 1.5 cable glands are available on page 7.
Connection to a Machine
As illustrated in Figure 2, a normally closed safety contact (i.e., a safety contact that is
closed when the actuator is engaged) from each of two safety switches per interlocked
guard must connect to a 2-channel safety module or safety interface in order to achieve
a control reliable interface to the master stop control elements of a machine. Examples of
appropriate safety modules include 2-channel emergency stop (E-stop) safety modules
and gate monitor safety modules.
Two functions of the safety module or safety interface are:
1. to provide a means of monitoring the contacts of both safety switches for contact
failure, and to prevent the machine from restarting if either switch fails; and
2. to provide a reset routine after closing the guard and returning the safety switch
contacts to their closed position. This prevents the controlled machinery from restarting
by simply reinserting the safety switch actuators. This necessary reset function is
required by ANSI B11 and NFPA 79 machine safety standards.
Use only a positively driven, normally closed safety contact from each switch for
connection to the safety module. The normally open contact may be used for control
functions that are not safety-related. A typical use is to communicate switch status to a
process controller. Refer to the installation instructions provided with the safety modules
for more information regarding the interface of the safety module to the machine stop
control elements.
WARNING . . .
It must not be possible for
personnel to reach any
hazard point through an opened guard
(or any opening) before hazardous
machine motion has completely stopped.
Please reference OSHA CFR 1910.217
and ANSI B11 standards (see page 2) for
information on determining safety distances
and safe opening sizes for your guarding
devices.

CAUTION . . .
Electrical Installation
Two safety switches
must be used for each interlock guard
to achieve control reliability or Safety
Category 4 (per ISO 13849-1, EN 954-1) of
a machine stop circuit. Use of only one
safety switch per interlock guard is not
recommended.
In addition, normally closed safety contacts
from each of the two safety switches should
be connected to the two separate inputs of a
2-channel safety module or safety interface,
as illustrated in Figure 2. This is required to
provide monitoring for safety switch contact
failure, and to provide the necessary reset
routine, as required by IEC 60204-1 and
NFPA 79 machine safety standards.
WARNING . . .
Series
Connection of Safety
Interlock Switches
Monitoring multiple guards with a series
connection of multiple safety interlock
switches is not a Safety Category 4
Application (per ISO 13849-1, EN 954-1).
A single failure may be masked or
not detected at all. When such a
configuration is used, procedures must
be performed regularly to verify proper
operation of each switch.
Figure 2. Connect two redundant safety switches per interlock guard to an appropriate
2-channel input safety module.

Periodic Checks
We recommend that safety switches be checked at each shift change or machine setup
by a designated person (see below) for:
1. Breakage of the switch body or actuator,
2. Good alignment and full engagement of the actuator with the receptor,
3. Confirmation that the safety switch is not being used as an end stop,
4. Loosening of the switch or actuator mounting hardware, and
5. Verification that it is not possible to reach any hazard point through an opened guard
(or any opening) before hazardous machine motion has completely stopped.
In addition, we recommend that a qualified person check for the following on a periodic
schedule determined by the user based upon the severity of the operating environment
and the frequency of switch actuations:
1. Check the wiring chamber for signs of contamination.
2. Check the contacts for signs of deterioration or damage.
3. Inspect the electrical wiring for continuity and damage.
4. Verify that wiring conforms to the instructions on pages 3 and 4 of this data sheet.
A designated person is identified in writing by the employer as being appropriately trained
to perform a specified checkout procedure. A qualified person possesses a recognized
degree or certificate or has extensive knowledge, training, and experience to be able to
solve problems relating to the safety switch installation (ANSI B30.2).
Repairs
Do not attempt any repairs to the switch. It contains no field-replaceable
components. Return the switch to the factory for warranty repair or replacement.
If it ever becomes necessary to return a switch to the factory, please do the following:
1. Contact the Banner applications engineering department at the number or address
listed on the front cover. They will attempt to troubleshoot the system from your
description of the problem. If they conclude that a component is defective, they will
issue an RMA (Return Merchandise Authorization) number for your paperwork, and
give you the proper shipping address.
2. Pack the switch carefully. Damage which occurs in shipping is not covered by
warranty.
