Continuous
As visible in the internal logic network diagram (see
Figure 4
: diagram of internal logic network
),
the sixteen pulse generators can be entirely bypassed by selecting one of the eight filtered
synchronization inputs (TR1, TR2, TR3, TR4, TR5, TR6, TR7 or TR8). Moreover, the outputs can
operate continuously by selecting the last option.
Setting of the output multiplexers can be done using the serial RS485 or Ethernet interfaces.
12.6. Output protection
The output protection logic is used to prevent the light from getting overheated and thus damaged.
Inside each of the eight protection blocks there is an independent state machine comprising a couple
of timers. The first timer is used to constrain the turn-on time of the light (Ton) to be lesser than or
equal to a programmable value
TonMAX
. The second timer is used to constrain the turn-off time of
the light (Toff) to be greater than or equal to a programmable value
ToffMIN
.
The diagram in
Figure 7
: turn-on and turn-off times within limits
shows what happens when both
time constraints are satisfied. As visible in the diagram, the output follows the input.
