2-5-1-2. Waveform of safety outputs
When the safety outputs are in the ON state, they are cyclically turned OFF as shown below to test the
output circuit. When this OFF signal is fed back, the output circuit is diagnosed as normal. If the output
signal does not include an OFF pulse signal due to short-circuit, etc, the receiver diagnoses a failure in
the output circuit or wiring, and it enters the LOCKOUT state.
