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
[1].
