4. Emerge ncies
To facilitate the use of the modem, tracking and display of emergencies are provided.
4.1. Emergency 1 (incorrect input power supply)
Emergency 1 occur s when the i nput p ower sup ply devi ates f rom the perm issibl e value. The modem stops working and it sh uts down the GSM module power. A perm anent red LED signals that t he emergency has occurred. The recovery is possible only when the input power supply is re-established.
4.2. Emergency 2 (incorrect module power supply)
Emergency 2 occurs when the GSM module power supply deviates from the permissible value. The modem stops working and i t shuts off the GSM modul e power. A red LED signals that the emergency has occurred (0.5s on / 0.5s off). The recovery is possible only if the module power supply is re-established within 10 seconds after the em ergenc y occurred. If withi n 10 seconds the m odul e power supply r em ains incorr ect ( with a correct input power supply), the modem goes into the waiting mode meaning that the modem’s power suppl y is turned off, t he emergency i ndicati on is preserv ed. T he waiting mode c an be t erminated only after the power is completely disconnected.
In case of repeated emergency, the modem should be serviced.
4.3. Emergency 3 (GSM module failed to start)
Emergency 3 occurs if the GSM m odule does not t urn on or i s absent. A r ed LED signal (0.25s on / 0. 25s off / 0.25s on / 1s off) turns on after a precise determination by the modem of the emergency situation (~15 sec). The recovery is possible onl y af ter a successf ul launch of the G SM module. After 10 unsucce ssful attempts to launch the module, the modem goes into the waiting mode meaning that the modem’s power supply is turned off, the em ergency i ndi cati on i s preserv ed. T he waiti ng mode can be t erm i nated onl y af t er t he power is complet ely disconnected.
In case of repeated emergency after the modem is turned back on, the modem should be serviced.
