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. 1. Mechanical Installation 2. Rotating the Actuator Head 270 180 2. 90 0 1. 3. 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. Pull holding clamp 2. Turn actuator head 3. Push holding clamp Figure 1. Features 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. Banner Engineering Corp. * Minneapolis, MN U.S.A. www.bannerengineering.com * Tel: 763.544.3164 P/N 59622 rev. E Machine Safety Switches - SI-LS83 and SI-LS100 Series Electrical Installation WARNING . . . 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. 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. Input Channel #1 Safety Switch #2 Single gate or guard (2-channel E-stop Module 2-channel Gate Monitor Module, etc.) 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 2. Connect two redundant safety switches per interlock guard to an appropriate 2-channel input safety module. P/N 59622 rev. E 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 Input Channel #2 2-channel Safety Module CAUTION . . . Electrical Installation Two functions of the safety module or safety interface are: Safety Switch #1 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. 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. Banner Engineering Corp. * Minneapolis, MN U.S.A. www.bannerengineering.com * Tel: 763.544.3164 Machine Safety Switches - SI-LS83 and SI-LS100 Series 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 o not attempt any repairs to the switch. It contains no field-replaceable D 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.
