Safety Module Features
Safety Input Fault Recovery
If an error is detected, the safety input data remains in the OFF state. To
activate the safety input data again, complete the following steps.
1. Remove the cause of the error.
2. Place the safety input (or safety inputs) into the safe state.
3. Allow the Input Error Latch Time and another 10 seconds to elapse.
After the steps are completed, the I/O indicator (red) turns off. The input data
is now active.
Safety Input Delay Time
You can increase the time that it takes for an input point to transition from On
to Off and Off to On on the 5069-IB8S or 5069-IB8SK module. The increase
in time is a delay of the signal from the module to the controller.
The delay time is in addition to the RPI, the parameter that defines a rate at
which the owner-controller and the module exchange data (2…500 ms). For
example, if you set the RPI at 10 ms and use an input delay time of 2 ms, the
signal from the module to the controller is 12 ms.
An increase in the time it takes to transition from one state to another
improves noise immunity within a signal.
