SSA-EB Series Lighted Emergency Stop Push Buttons Illuminated 30mm Mount Electro-Mechanical Push Buttons Features Rugged design easy installation with no assembly or individual wiring required Push-to-stop, twist-to-release, or pull-to-release operation per IEC60947-5-5 Latching design complies with ISO 13850 direct (positive) opening operation per IEC 60947-5-1 Compliant with ANSI B11.19, ANSI NFPA79, and IEC/EN 60204-1 Emergency Stop requirements Safe Break Action ensures N.C. contacts will open if the contact block is sepa- rated from the actuator 8-pin M12/Euro-style Quick Disconnect Models with YELLOW and RED indication of actuation (armed or depressed/ latched button) Emergency Sto legend included Models SSA-EB series aremushroom-styl electro-mechanical emergency stop push buttons. When the button is armed, the switch s safety contacts (N.C.) are closed and its monitoring contacts (N.O.), if present, are open. When the button is pushed, the switch s safety contacts open and the monitoring contacts close. The contacts remain in this condition until the push button is manually rearmed by pulling or twisting clockwise the red push button actuator. The SSA-EB1P..-..ECQ.. series has a 30 mm mounting base similar to Banners OTB, VTB, and STB Optical Touch Buttons for ease of mounting without requiring an additional enclosure. The EZ-LIGHT illumination logic allows for easy identification of a pushed/actuated button. An armed button is either a steady yellow illumination or OFF, a pushed/actuated button is indicated by a red flashing illumination. An optional input allows an armed button to illuminate a steady red to indicate a machine stop or emergency stop condition. Models Model E-Stop Contacts Indicators SSA-EB1PLYR-12ECQ8 2 N.C./1 N.O.

Banner Engineering Corp. has made every effort to provide complete application, installation, operation, and maintenance instructions. Please direct any questions regarding the use or installation of this product to the factory applications depart- ment at the telephone numbers or address found at SSA-EB Series Lighted Emergency Stop Push Buttons WARNING: Not a Safeguarding Device An Emergency Stop Device is not considered a safeguarding device because it requires an overt action by an individual to stop machine motion or hazards. (A safeguarding device limits or eliminates an individual s exposure to a hazard without action by the indi- vidual or others.) Because an individual must actuate the device for it to function, these devices do not fit the definition of a safeguarding device and cannot be substituted for required safeguarding. Refer to the relevant standards to determine those requirements. Emergency Stop Considerations ANSI NFPA 79, ANSI B11.19, IEC/EN 60204-1, and ISO 13850 specify emergency stop requirements, including the following: Emergency-stop push buttons shall be located at each operator control station and at other operating stations where emergency shutdown is required. Stop and emergency-stop push buttons shall be continuously operable and readily accessible from all control and operating stations where located. Do not mute or bypass E-stop buttons. Actuators of emergency-stop devices shall be colored red. The background immediately around the device actuator shall be colored yellow (where possible). The actuator of a push-button-operated device shall be of the palm or mushroom-head type. The emergency-stop actuator shall be a self-latching type. WARNING: Emergency Stop Functions Do not mute or bypass any Emergency Stop device. ANSI B11.19, ANSI NFPA79 and IEC/EN 60204-1 require that the Emergency Stop function remain active at all times. WARNING: Multiple Switching Devices Whenever two or more devices are connected to the same safety module (controller): Contacts of the corresponding pole of each switch must be connected together in series. Never connect the contacts of multiple switches in parallel. Such a parallel connection defeats the switch contact monitoring ability of the Module and creates an unsafe condition which could result in serious injury or death. Each device must be individually actuated (engaged), then released (or re-armed) and the safe- ty module reset. This allows the module to check each switch and its wiring to detect faults. This check must be performed during the prescribed checkouts. Failure to test each device individually in this manner could result in undetected faults and create an unsafe condition which could result in serious injury or death. Installation and Maintenance The device must not be affected by environmental conditions. Install the device so that operation is not impeded, but should be protected against inadvertent operation (for example, accidental actuation by being bumped or leaned against). Do not operate the switch using a tool. Do not expose the switch to excessive shocks and vibrations, otherwise the switch may be deformed or damaged, causing malfunction or operation failure. Hardware includes jam nut, lock washer, lock ring, and seal washer. The lock ring may be used to prevent switch rotation if a 5mm hole keyway is provided. Electrical installation must be made by qualified personnel and must comply with NEC (National Electrical Code), ANSI/NFPA 79 or IEC/EN 60204-1, and all applicable local standards. It is not possible to give exact wiring instructions for a device that interfaces to a multitude of machine control configurations. The following is general in nature it is recommended to perform a risk assessment to ensure appropriate application, interfacing/hookup, and risk reduction (see ISO 12100 or ANSI B11.0). 2 www.bannerengineering.com - tel: 763-544-3164 P/N 162754 web Rev.
