8.2 Start-up procedure
1
IMPORTANT: Make sure that the initial data reset “jumper” is not inserted. Otherwise, the previous
configuration data would be lost and the initial data restored.
2 Power up the GSM-BUS communicator: the
“ON”
LED blinks to indicate the phase of initializing the GSM-
BUS communicator
3 After the initialization phase ends, the ON LED stops blinking and lights up steady to signal that the start-up
phase has been successful After the start-up phase, the
“ON”
LED signals there is mains voltage
4 Approximately 20 s after powering up, the GSM-BUS communicator activates the phone module start-up
procedure: the “ ” LED starts blinking quickly
5 If the “ ” LED starts blinking slowly, the phone module start-up procedure and its subsequent registering on
the GSM network have concluded successfully
The following table gives the “ ” LED signals according to the GSM module status
8.3 GSM signal detection:
1 Check the start-up procedure has concluded correctly and the GSM module has been registered on the
GSM network: the “ ” LED blinks slowly
2 Press the “GSM” button
3 The yellow LEDs will show the strength of the GSM signal, whose value is indicated by the “bars” corre-
sponding to the LEDs on
Installation is possible even with only the “ ” LED on (minimum level)
Installation is not possible when there is no GSM signal In this case, after trying to change the position of the
antenna without any success, it is necessary to find a zone covered by the GSM signal where the GSM-BUS
communicator can be positioned
