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.

Mechanical Installation

Horizontal or Vertical Actuation

Before installation, orient the switch actuator head for either horizontal (at a right angle
to the switch length) or vertical (in-line with the switch length) actuation. The switch is
shipped with the actuator head in the horizontal position (Figure 1). If this is the desired
orientation, install the M3 x 15 mm tamper-proof (one-way) screw, which is found in a
plastic bag, stored in the wiring chamber (see page 6 for information on opening the
wiring chamber access door).

If vertical actuation is required, remove the head by pulling straight up and off (Figure 2).
Re-orient the actuator head, and slide it back on in the new position until it snaps into
place. Install the tamper-proof screw, as shown in Figure 3.

Rotating Actuator Head to Desired Position

The actuator head may be rotated in increments of 90° to create eight possible actuator
engagement positions (i.e., four horizontal plus four vertical positions). To rotate the
head, pull the holding clamp forward, rotate the head (in either direction) to the desired
position, and push the holding clamp back in to lock. The head may be rotated with the
actuator either engaged or removed (Figure 4).

Installing the Switch and Actuator

NOTE: All mounting hardware is supplied by the switch user. The fasteners must be of

sufficient strength to avoid incidental breakage. Use of permanent fasteners or
locking hardware is recommended to prevent loosening or displacement of the
actuator and switch body.

The mounting holes in the switch body accept M5 (#10) screws. There are four holes
on a mounting pattern of 30 x 124 mm (see dimension drawing of switch, page 10). See
page 11 for dimensions of the actuator mounting holes.

Position the switch, with its actuator fully engaged, at the mounting location and mark
the mounting holes. Fasten the switch body and the actuator in place. The rigid in-line
actuator includes floating sleeves in the mounting holes to allow some forgiveness for
switch-to-actuator alignment. If the rigid in-line actuator is used, take care to not over­tighten the actuator fasteners so as to allow this movement. After the mounting hardware
is secure, check the actuator/switch engagement for misalignment and binding.

Figure 3. Vertical actuator head position:

Install tamper-proof screw.

IMPORTANT: 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 wiring chamber. A switch and its actuator must never be used as a
mechanical stop.

Manual Release for Spring Lock Models

Models with spring lock/solenoid unlock may be unlocked manually by rotating the unlock
mechanism, using an M3 Allen wrench (not supplied). First loosen the security screw
(see dimension drawing of switch, page 10), then turn the unlock mechanism in either
direction to the position.

IMPORTANT: After the switch is installed, check to be certain that the unlock
mechanism is in the position, and that the security screw is tight and covered with

Electrical Installation

Access to Wiring Chamber

The wiring chamber is accessed via the hinged door. Simply insert a flat-blade
screwdriver, as shown in Figure 5, and pry gently down to open. Select the best wiring
entrance and thread in the ½" x 14 NPSM conduit adapter (supplied), or the optional M20
x 1.5 cable gland (page 12). The switch knockout will break loose with the final turn of
the conduit adapter or cable gland.

To open wiring chamber:

1. Insert the screwdriver
blade into slot in cover to
pry cover open.

To connect wires to terminals:

1. Insert the screwdriver blade into the slot below the
desired wiring terminal.

2. Twist the screwdriver blade in the slot to open the
terminal jaws; insert wire.

3. Hold wire in place and remove screwdriver.

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 6. 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.

Machine Safety Switches –

SI-LS42 Series Locking Style Switch

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.

Connection to a Machine

Four contacts are offered. Two are safety contacts which must be wired in series, and
the other two are considered monitoring contacts which may be used, if desired.

The contact between terminals 11 and 12 or 21 and 22 is a safety contact which is
closed (i.e., it conducts) when the actuator is engaged. The contact between terminals 13
and 14 is the associated actuator monitoring contact.

The contact between terminals 31 and 32 is a safety contact which is closed when
the solenoid is in its locking state. The contact between terminals 43 and 44 is the
associated solenoid monitoring contact.

See the switching diagrams on pages 3 and 4 for contact state information.

Solenoid voltage connects to terminals E1 (+) and E2 (-).

As illustrated in Figure 6, the normally-closed safety contacts (i.e., safety contacts that
are closed when the actuator is engaged and the solenoid is in its locking state) from
each of two safety switches per interlock 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 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 positively-driven, normally-closed safety contacts from each switch for
connection to the safety module. The normally-open contacts may be used for control
functions that are not safety-related. A typical use is to communicate with 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

Periodic checks should be performed only by Designated Persons or Qualified Persons,
as specified below. Safety switches should 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, 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 that wiring conforms to the instructions on pages 8 to 10 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

NOTE: 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.
