F www.bannerengineering.com - tel: 763-544-3164 3 Machine Safety Switches Rotating Actuator Head The actuator head may be rotated 180 to create four possible actuator engagement locations. To rotate the head: 1. Open the wiring chamber door, as shown. 2. Using a small flat-blade screwdriver, dislodge the two locking tabs located on the backside of the switch. 3. Lift the head straight off of the switch body. 4. Rotate the head, as shown, and reinstall it on the switch body. Mechanical 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. IMPORTANT: A safety switch must be installed in a manner that discourages tampering or defeat. Mount switches to prevent bypassing of the switching function at the terminal chamber. A switch and its actuator must never be used as a mechanical stop. Overtravel may cause damage to switch. All mounting hardware is supplied by the user. The fasteners must be of sufficient strength to guard against incidental breakage. Use of permanent fasteners or locking hardware is recommended to prevent loosening or displacement of the actuator and switch body. Use for permanent mounting M5 (#10) Clearance Use ONLY for alignment during installation Snap-On Cap 1. Temporarily mount the switch body in place, with its actuator inserted, using the slotted 5 mm holes. NOTE: The slotted holes in the switch body must ONLY be used for alignment during installation. The round 5 mm holes (only) must be used for permanent mounting to prevent loosening or displacement of the actuator and the switch body. Only M5 (#10) screws (user supplied), should be used. 2. Slide the switch body on its temporary fasteners to locate and mark the actuator mounting position. Remove the actuator from the switch body and mount it using tamper-resistant 5 mm (#10) hardware (e.g., Torx-head screws, rivets, etc.). Slide the switch body on its temporary fasteners to locate and mark the actuator mounting position. Remove the actuator from the switch body and mount it using tamper-resistant 5 mm (#10) hardware (e.g., Torx-head screws, rivets, etc.). NOTE: The non-adjustable in-line actuator includes floating sleeves in the mounting holes to allow some forgiveness for switch-toactuator alignment. Take care to not over-tighten the actuator fasteners so as to allow this movement. This actuator also includes a snap-on cap to cover the fasteners. 4 www.bannerengineering.com - tel: 763-544-3164 P/N 049370 Rev. F Machine Safety Switches 3. Engage the actuator into the switch body. Align them so that the actuator is fully engaged. Fasten the switch body in place using two tamper-resistant 5 mm (#10) screws through the two round holes. Check switch engagement for misalignment and binding. Electrical Installation 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). Select the best wiring entrance and thread in the 1/2" x 14 NPT conduit adapter (supplied), or the optional M20 x 1.5 or M16 x 1.5 cable gland. The switch knockout will break loose with the final turn of the conduit adapter or cable gland (i.e., as it bottoms out). Connection to a Machine As illustrated below, 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 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 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 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 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. P/N 049370 Rev.

Single gate or guard 2-channel Safety Module (2-channel E-stop Module 2-channel Gate Monitor Module, etc.) Figure 1. Connect two redundant safety switches per interlock guard to an appropriate 2-channel input safety module. Periodic Checks Safety switches should be checked at each shift change or machine setup by a designated person for: 1. 2. 3. 4. 5. Breakage of the switch body or actuator, Good alignment and full engagement of the actuator with the receptor, Confirmation that the safety switch is not being used as an end stop, Loosening of the switch or actuator mounting hardware, and 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 manner 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. 6 www.bannerengineering.com - tel: 763-544-3164 P/N 049370 Rev.
