3.7 Error Conditions
3.7.1 Health Failure Conditions
In ready mode, the device may fail to turn on under an error condition. Instead of
turning the device on when the On/Off button is pressed, the Status LED will turn red
to indicate an error state.
To display the error state, continue to hold the On/Off button. The error condition will
be displayed using the Clock Sync and Record LEDs. Each possible state will be clocked
out in order, with one second delay between each state, until the highest state that is
in error is reached. The respective error states, in order, are:
1. Cavity temperature sensor 1
2. Cavity temperature sensor 2
3. Battery temperature
4. Charging status
5. State of charge (no auxiliary power)
6. State of charge (auxiliary power present)
7. Battery voltage
A red Clock Sync LED indicates that the specific health parameter falls beyond the
specified norms. A green led indicates nominal conditions.
A red Record LED indicates that a specific health parameter could not be read from
internal systems. This represents a more serious, but rare, condition. A persistent red
Record LED indicates a hardware failure. A green led indicates nominal conditions.
3.7.2 Recovery conditions
The Vecto III continuously performs internal health checks. Should one of these checks
fail, the device will attempt to recover itself. In case the battery voltage or temperature
readings exceed operating limits, the device will perform a controlled shutdown which
is indicated by an orange Status LED. An uncontrolled shutdown is indicated by a solid
red Status LED.
Once the device is powered down, the health check system will flash the red Status
LED to indicate a non-user initiated shutdown. The shutdown reason can be obtained
using the method described in Section 3.7.1. The device will attempt to power up again
if all health checks passed.
