Hi sir:
Please do this 1) in the secondary Tap Transfer Measure with 10% of Tolerance:
X1: Plug- Pin base input voltages
1 24V AC
2
3
4 24V AC
5
6 24V AC
7
8 28V AC
9
10 24V AC
2) X2: Plug- Pin base input voltages
Pin Function
7
20V ac
13
1
14 20V AC
10
12 27V AC
8
15 15V AC
4
2 20V AC
5
9 17.5V AC
11
6 17.5V AC
3 not assigned
3) If everything is o.k in the 2 steps before go to the next steps in the GSM Rectifier Module
X3 Socket base output voltages
Pin Function
1 24V DC
4
2
3 24V DC
5
6 24V DC
7
10 28V DC
8
9 24V DC
X4 Socket base output voltages
Pin Function
2
5 20V AC
1
6 20V AC
4
8 27V AC
3
7 15V AC
X5 :Socket base output voltages
Pin Function
3 20V AC
2
1 17.5V AC
4
5 17.5V AC
6
4) Now measure with a Good DMM :NTE board power supply very well, the tolerance must be 4% up or down
Power supply board for 12V DC
Power supply board for 8V DC
Power supply board for –8V DC
Power supply board for 24V DC
Power supply board for 5V DC
How you must understand, IF ANY of the Voltages show in the 1+2+3+4 is a) missing b) or out of tolerance, the cpc will NOT work, you can replace ALL the electronic board, and Always will be have the same problem. o.k??
Do carefully and with Patience.
Blessing
