Flashing LED Signals
Flashing LED indicators, or combinations of flashing LED indicators,
are used to indicate certain controller states, or transitions from one
state to another.
ERROR LED - 4 Flashes
The ERROR LED alone will flash four times to indicate that the
controller is entering the download routine. This indicates that Switch
5 is in the ON position during a power-on or hard reset. With a
terminal correctly configured and connected to COM2, the download
menu will be displayed.
ERROR and CONFIG LEDs - 4 Simultaneous
Flashes
The ERROR and CONFIG LEDs will flash simultaneously four times
to indicate that (CTRL-D) has been received within the first seven
seconds of power-on or hard reset. With a terminal correctly
configured and connected to COM2, the configuration menu will be
displayed.
ERROR and CONFIG LEDs - 4 Alternating Flashes
The ERROR and CONFIG LEDs will alternately flash four times to
indicate that the controller is entering operating mode and is ready to
receive commands on COM1.
ERROR RED Flashes red for 0.5 seconds to
indicate the unsuccessful execution of
an ABx command.
