WARNING:
• Interfacing OSSD Outputs to Machine Inputs
• Failure to properly interface the OSSD Outputs to the guarded machine could result in serious
injury or death.
• To ensure proper operation, the Banner device output parameters and machine input parameters
must be considered when interfacing the Banner device OSSD outputs to machine inputs. Design
the machine control circuitry so that the maximum load resistance value is not exceeded and the
maximum specified OSSD Off-state voltage does not result in an On condition.
External device monitoring (EDM) is a function used to monitor the state of the external, positively guided (mechanically
linked) machine control contacts (Final Switching Devives (FSD) and/or MPCEs). The SSA-ISD Connect does not include the
EDM function. As a result, the SSA-ISD Connect should be used with an external safety monitoring device that monitors the
status of the two SSA-ISD Connect OSSDs and is capable of providing the EDM function.
Examples of appropriate external safety monitoring devices include the Banner SC10-2ro Safety Controller.
WARNING:
• The SSA-ISD Connect does not have external device monitoring (EDM).
• If EDM is required for the application, it must be implemented in the external control.
2.4.1 Fault Tolerant Output Feature
Faults that do not immediately compromise the safe operation of the SSA-ISD Connect (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 SSA-ISD Connect
will flash the ISD red LED.
Use this fault tolerance 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 SSA-ISD Connect will immediately cause a lockout condition and the
OSSDs will turn off.
