Technical data

• All colors (signals) are acknowledged and they will illuminate in steady state.
• Incoming additional signals with lower priority will illuminate when they
become the highest priority in steady mode.
• One or more signals with higher priority are changing to ON after an
acknowledgement.
• The higher priority color (signal) will illuminate in flash mode.
See
Figure 48 and Figure 49 for these two principles.

Figure 49: LHMI LED operation mode LatchedAck-F-S Prio / 2
LED operation mode LatchedAck-S-F
This operation mode operates exactly as the one described above (LatchedAck-F-S).
The only difference is that the illumination mode is changed. Flash mode instead of
steady mode and steady mode instead of flash mode.
