Suggestion
1
Fail_Device
Inform the service agency for repair.
2
Alm_Initialization
Check external time source if the initialization failure has lasted for a long
period.
3
Alm_Device
Eliminate all the other alarms firstly.
4
Alm_DualDev
Verify the setting "Opt_DualDev" along with the device hardware.
5

Check the rated input voltage and the PWR module 1.
6
Alm_Pwr2_Device
Check the rated input voltage and the PWR module 2.
7
Alm_Receiver_SatlCh1
Inform the service agency for repair.
8
Alm_Receiver_SatlCh2
Inform the service agency for repair.
9
