Safe output status
Automatically tests the safety beams before each gate cycle. (eg as required by

In order for this feature to work, the power supply negative of the beam
receiver beam transmitter must be wired to the SAF COM terminal of the
controller
The time taken for the gate to open again after it has come to a stop is
approximately three seconds
Example:
Autoclose override time set to five seconds: Total time to temporarily
disable the PIRAC feature is approximately eight seconds
(5s + 3s = 8 seconds)
