LED operation mode LatchedAck-S-F
The LatchedAck-S-F mode operates in a similar manner as the LatchedAck-F-S
mode. However, on receiving a binary On signal, the LED enters a steady lit state.
When acknowledged and the signal remains On, it starts flashing.

Figure 56: LHMI: LED operation mode LatchedColl-S
A LED operating in the LatchedColl-S mode enters a steady lit state on receiving a
binary On signal. The LED remains lit even if the signal immediately transitions to
Off (pulse). When acknowledged, the LED is switched off, unless the attached
signal remains On. SeeFigure 56 for details.
