(2) Voltage Label Check
Be sure to confirm voltages on Voltage label before conducting adjustment.
Example
Vbw : 115.2
Vsw1 : 220.2
VP : 249.8
Vsw2 : 210.1
Voltage Label
(s190.0/d70.0)115.2/220.2/249.8/210.1

(1) Adjustments
Follow the procedure below.
1-1)Conduct “(3)Adjustment of Vsw1 & Vsw2”and“(4)Adjustment of Vbw& Vp”, when High Voltage Board is replaced.
1-2) There is no need of adjustment if Board other than High Voltage Board.
(3) Adjustment of Vsw1 & Vsw2
(Caution) Use the nearest chassis for grounding.
VR3 Vsw1
TP328 Vsw1
VR4 Vsw2
TP310 Vsw2
Vsw1 : Adjust VR3 so that the voltage between Test Pad (TP328) and GND becomes
“Rated Voltage on Label ± 0.5V”.
Vsw2 : Adjust VR4 so that the voltage between Test Pad (TP310) and GND becomes
“Rated Voltage on Label ± 0.5V”.
High Voltage Board
