21.
If number 3-4 and number 8 of J59 socket are loaded as 3,5Ω 14W, DC 7V±%3 can be
measured.
22.
The fuse is inserted in F5 fuse holder as definer in GENERAL MATERIAL LIST.
23.
Number 2 of F7 fuse is applied to DC +24V from 0-24V point of power supply. After the
procedure, D22 LED is ON. Number 3-4 of J59 is measured as ground of measuring device;
number 6-7 is measured as active point of the device. DC 12V±%2 is measured.
24.
If number 3-4 and number 6-7 of J59 socket are loaded as 6Ω 24W, DC 12V±%3 can be
measured.
25.
The fuse is inserted in F3, F4, F7 fuse holder as definer in GENERAL MATERIAL LIST.
After completing the test by running all the functions, the board should be labelled and stored in
available conditions.
