Internal temperature of
housing
Behavior
–25 °C ... –20 °C
“Ready” LED continuously flashes green (warm-up phase).
Device is not operational (communication channel still disabled)
until the internal temperature has increased to –20 °C as a result
of the heat generated by the electronics. Duration approx. 2 min.
From -20 °C
“Ready” LED permanently lights up green.
The device has started regular operation.
Once the supply voltage has been applied, the device uses integrated temperature
sensors to measure its internal temperature. This is performed by the device while
booting.
