LED Lights
– I/O Board
The I/O Board has 4 LEDs to indicate the status of the heaters, power supply, and microcontroller
(I/O Board setup parameters). The locations of these LEDs are shown in Appendix A. An explanation
is shown in the table below. Note: Green + Red combination may appear as Orange.
#
Function
Color/Status
1
Camera heater status
Green
– heater enabled by microcontroller but no current is running
Red
– heater current is running but heater is not enabled
Green
+
Red
– heater is enabled and current is running (Normal state)
2
Microcontroller status
Green
– I/O Board setup parameters are all OK (Normal state)
Red
– At least one I/O Board parameter is not OK
(Possible errors are demist heater, camera heater, and/or LED
Ring Light boards)
3
Power indicator
Green
– 24V input voltage present. 12V regulated voltage not present.
Red
– 12V regulated voltage present. 24V input voltage not present.
(Note: this voltage can be powered down from the microcontroller
if temperature gets too high or too low)
Green
+
Red
– 24V input and 12V regulated voltages present (Normal
state)
4
Demist heater status
Green
– heater enabled by microcontroller but no current is running
Red
– heater current is running but heater is not enabled
Green
+
Red
– heater is enabled and current is running (Normal state)
