4.2.4 Automatic Shutdown
Automatic shutdown takes effect if:
The ALAS5V board is exceeding the critical limits of overtemperature or undertemperature
Undervoltage or overvoltage is detected
The automatic shutdown procedure is equivalent to the power down initiated with the AT^SMSO
command, i.e. ALAS5V logs off from the network and the software enters a secure state avoid-
ing loss of data.
Alert messages transmitted before the device switches off are implemented as Unsolicited Re-
sult Codes (URCs). The presentation of the temperature URCs can be enabled or disabled with
the command AT^SCTM. The URC presentation mode varies with the condition, please see
Section 4.2.4.1 to Section 4.2.4.4 for details. For further instructions on AT commands refer to
