Corp. makes no claim regarding a specific recommendation of any organization, the accuracy or effectiveness of any
information provided, or the appropriateness of the provided information for a specific application.
WARNING:
• Not a safeguarding device
• Failure to follow these instructions could result in serious injury or death.
• This 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 individual or others. This device cannot be
substituted for required safeguarding. Refer to the applicable standards to determine those
requirements.
1.3 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:
• Do not mute or bypass any emergency stop device
• Muting or bypassing the safety outputs renders the emergency stop function ineffective.
• ANSI B11.19, ANSI NFPA79 and IEC/EN 60204-1 require that the emergency stop function
remain active at all times.
WARNING:
• Connect two or more devices to the same safety module (controller) in series
• Connecting devices in parallel defeats the switch contact monitoring ability of the module and
creates an unsafe condition that could result in serious injury or death.
• Failure to test each device individually in this manner could result in undetected faults and create
an unsafe condition that could result in serious injury or death.
• Connect the contacts of the corresponding pole of each switch in series. Never connect the
contacts of multiple switches in parallel. Individually actuate (engage) each device, then release
(or re-arm) and reset the safety module. This allows the module to check each switch and its
wiring to detect faults. Perform this check during the prescribed checkouts.
1.4 Overview
The SSA-EB1PLx-0Dx Series Lighted Emergency Stop Button with ISD is a mushroom-style electro-mechanical emergency
stop push button. When the button is armed and the device input requirements are satisfied, the two, solid-state PNP
output signal switching devices (OSSDs) are on (conducting). When the button is pushed, the OSSDs are off (not
conducting). The OSSDs remain in this condition until the push button is manually re-armed by pulling or twisting clockwise
the red push button actuator.
The SSA-EB1PLx-0Dx..ECQ.. series has a 30 mm mounting base similar to Banner's OTB, VTB, and STB Optical Touch
Buttons for ease of mounting without requiring an additional enclosure. The SSA-EB1PLx-0Dx..ED1Q.. series has a flat
mounting base for ease of mounting without requiring an additional enclosure.
The illumination provides easy identification of a pushed/actuated button. An armed button will light a steady yellow or
green illumination or be OFF (depending on model). A pushed/actuated button is indicated by a red flashing illumination.
Internal or external faults are indicated by a double-flashing red illumination.
