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

Limit-Switch Style Machine Safety Switches

Overview

Easy Access Rotating the Actuator Head

The wiring chamber is accessed via a hinged door. Simply insert a
flat-blade screwdriver, as shown, and pry gently down to open.

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 on page 6).

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 discourages 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

WARNING: Hazard Point
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 for information on determining safety
distances and safe opening sizes for your guarding devices.

Limit-Switch Style Machine Safety Switches

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. 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 safety interlock switches may result in a failure be­ing masked or not detected at all. When such a configuration is used, periodic checks must be performed
regularly to verify proper operation. All failures must be immediately corrected ( e.g. immediately replacing
a failed switch), or the loss of the safety stop signal or an inappropriate reset could lead to serious injury or
death.

Access to the Wiring Chamber

The wiring chamber is accessed via the hinged door (see Overview on page 3). 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, see Accessories on page 7 .

Connection to a Machine

As illustrated in Figure 1. Switch Wiring to Safety Module on page 4, 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.

NOTE: Refer to the installation instructions provided with the safe­ty module for information regarding the interface of the safety mod­ule to the machine stop control elements.

Figure 1. Switch Wiring to Safety Module

Connect two redundant safety switches per interlock guard to an
appropriate 2-channel input safety module.

Two functions of the safety module or safety interface are to:

1. 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

4 www.bannerengineering.com - tel: [phone] P/N 059622 Rev. G

Limit-Switch Style Machine Safety Switches

2. 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.

Periodic Checks

Safety switches should be checked at each shift change or machine setup by a designated person 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, a qualified person should 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 the wiring conforms to the instructions given in this datasheet.

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 Module. It contains no field-replaceable components. Return it to the factory for warranty repair

or replacement by contacting Banner Factory Application Engineering. They will attempt to troubleshoot the system from your description
of the problem. If they conclude a component is defective, they will issue a return merchandise authorization (RMA) number for your
paperwork and give you the proper shipping address.

Pack the Module carefully. Damage that occurs in return shipping is not covered by warranty.

CAUTION: Abuse of Module After Failure
If an internal fault has occurred and the Module will not reset, do not tap, strike, or otherwise attempt to
correct the fault by a physical impact to the housing. An internal relay may have failed in such a man-

ner that its replacement is required.

If the Module is not immediately replaced or repaired, multiple simultaneous failures may accumu­late such that the safety function can not be guaranteed.
