SSA-EBM Series Emergency Stop Push Buttons with OTBVP6 Push-to-Stop, Twist-to-Release Electro-Mechanical Push Buttons Features Push-to-stop, twist-to-release operation per IEC60947-5-5 Latching design complies with ISO 13850 direct (positive) opening operation per IEC 60947-5-1 OTBVP6 provides normally open PNP output for a variety of functions 8-pin M12/Euro-style Quick Disconnect Yellow plastic enclosure Rugged design easy installation with no assembly or individual wiring required 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 twisting clockwise the red push button actuator. The OTBVP6 is intended as a general-purpose initiator, and by itself is not a safety device. The output is ON when an object (for exam- ple, an individuals finger) is placed in the sensing area. A field cover is included to minimize the possibility of unintended or inadvertent activation. If this cover is missing or has become lost or damaged, contact Banner for a no-charge replacement. See the OTB datasheet p/n 28436, available at SSA-EBM Series Emergency Stop Push Buttons with OTBVP6 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). All hardware is user- supplied. 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).
