Notes
• Please refer to the ''Hardware Interface Description'' for specifications on critical temperature ranges.
• To avoid damage the module will shut down once the critical temperature is exceeded. The procedure is
equivalent to the power-down initiated with
• URCs indicating the alert level ''1'' or ''-1'' are intended to enable the user to take appropriate precautions,
such as protect the module or battery from exposure to extreme conditions, or save or back up data etc. The
presentation of ''1'' or ''-1'' URCs depends on the settings selected with the write command:
If =0: Presentation is enabled for 15 s time after the module was switched on. After 15 s operation, the
<n>
presentation will be disabled, i.e. no URCs will be generated.
If = 1: Presentation of ''1'' or ''-1'' URCs is always enabled.
<n>
• Level ''2'' or ''-2'' URCs are followed by immediate shutdown. The presentation of these URCs is always
enabled, i.e. they will be output even though the factory setting
• If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure
the temperature and to deliver alert messages, but deactivates the shutdown functionality. Once the call is
terminated full temperature control will be resumed. If the temperature is still out of range ME switches off
immediately.
