2.3.1 Fault-Tolerant Output Feature
Faults that do not immediately compromise the safe operation of the SSA-EB1PLx-0Dx (for example safety output to
external potential, crosswire short safety output) result in a delayed switch-off of the safety outputs.
The safety outputs switch off when the error warning exceeds 20 minutes. In case of error warning, the E-stop will double-
flash red.
Use this fault-tolerant output feature to run down the machinery in a controlled manner. After fixing the fault, the error
message is confirmed by a voltage reset. The safe outputs enable and allow a restart.
Faults that directly affect the safe operation of the emergency stop device immediately cause a lockout condition and the
OSSDs turn off.

Figure 5. Single SSA-EB1PLx-0Dx Series Lighted Emergency Stop Button with ISD with SC10-2ro.
The SSA-EB1PLx-0Dx Series Lighted Emergency Stop Button with ISD can be connected in series or individually to a
compatible Banner XS26-2 or SC10-2ro Safety Controller. See the XS26-2/SC10 Safety Controller Instruction Manual for
additional details regarding input terminal combinations compatible with ISD.
2.4.1 Wire the Device in Series
To connect two or more SSA-EB1PLx-0Dx buttons in series, follow these steps.
1. Connect the safety outputs of the last emergency stop device to a safety monitoring unit.
2. Connect the safety inputs of the first emergency stop device of the series to + 24 V DC.
3. Connect the safety outputs of the first emergency stop device to the safety inputs of the second emergency stop
(and second to third, etc).
4. When all the emergency stop devices are armed, the last emergency stop device of the series connection will turn
on its safety outputs.
5. If you are using an optional In-Series Diagnostic (ISD) module (SI-RFA-DM1), integrate the diagnostic module
between the last emergency stop device and the safety monitoring module in the series connection.
The status information can be retrieved from the diagnostic device.
Important: Verify the SSA-EB1PLx-0Dx emergency stop device and the safety monitoring module are
powered from the same power supply or the commons of the separate supplies are the same.
