Testing Board Physically:
Circuit components and PCB should be tested by physically and microscope and IPC-A-610D
CLASS II criteria and assembly directions should be validated.
Bar-coding order should be controlled and validated.
Electrical Tests:
1.
Power supply is set to series mode. Each channel is set to +24V and as a total of 48V.
2.
48V is applied from J2 socket.
3.
Available fuse is chosen for F1 fuse holder which is defined in GENERAL MATERIAL LIST.
4.
48V is applied by turning on the power supply. By observing, the current is not withdrawn
from power supply.
5.
Number 1 of J3 socket is the ground of measuring device, number 2 is the active point of
measuring device. DC24V±%2 is measured.
6.
Number 1 of J3 socket is the ground of measuring device, number 3 is the active point of
measuring device. DC24V±%2 is measured.
7.
Number 1 of J1 socket is the ground of measuring device, number 2 is the active point of
measuring device. DC24V±%2 is measured.
8.
Number 1 of J1 socket is the ground of measuring device, number 3 is the active point of
measuring device. DC24V±%2 is measured.
9.
3A is withdrawn from number 1 and 2 of J3 socket by 8Ω 71W load. Number 1 and 2 points are
measured as DC24V±%3.
10.
3A is withdrawn from number 1 and 2 of J1 socket by 8Ω 71W load. Number 1 and 2 points are
measured as DC24V±%3.
11.
Number 4 of J3 socket is the ground of measuring device, number 1 is the active point of the
measuring device. Number 2 of F8 fuse is applied to +24VDC from the 0-24V point of power
supply. Approximately 20mA is withdrawn and D19 LED is ON. Number 1 and 4 from J34
socket has 15VDC±%2.
12.
If number 1 and 4 of J34 socket are loaded as 15Ω 15W, DC 15V ±%3 can be measured.
13.
Number 4 of J3 socket is the ground of measuring device, number 7 is the active point of the
measuring device. Number 2 of F8 fuse is applied to +24VDC from the 0-24V point of power
supply. Approximately 20mA is withdrawn and D19 LED is ON. Number 4 and 7 from J34
socket has 15VDC±%2.
14.
If number 4 and 7 of J34 socket are loaded as 15Ω 15W, DC 15V ±%3 can be measured.
15.
Available fuse is chosen for F8 fuse holder which is defined in GENARAL METARIAL LIST.
16.
If number 1-4 and number 3-4 of J59 socket are loaded as 1,67Ω 15W, DC 15V±%2 can be
measured.
17.
Number 2 of F6 fuse is applied to DC +24V from 0-24V point of power supply. After the
procedure, D21 LED is ON. Number 3-4 of J59 is measured as ground of measuring device;
number 10-11 is measured as active point of the device.
18.
If number 1-4 and number 3-4 of J59 socket are loaded as 1,67Ω 15W, DC 15V±%2 can be
measured.
19.
The fuse is inserted in F6 fuse holder as definer in GENERAL MATERIAL LIST.
20.
Number 2 of F5 fuse is applied to DC +24V from 0-24V point of power supply. After the
procedure, D20 LED is ON. Number 3-4 of J59 is measured as ground of measuring device,
number 8 is measured as active point of the device. DC 7V±%2 is measured.
