3. L-PCB Assy
3-1. VCC21, VEE9 Voltage adjustment
1. Preparation
• AC adaptor or voltage regulator
• Multimeter
2. Adjustment procedure
(1) Adjust VR120 so that VCC21 (CP121) is 21.0 ± 0.3 V.
(2) Adjust VR130 so that VEE9 (CP133) is –9.0 ± 0.2V.
3. Notes
When not able to adjust using AC adaptor, use voltage regulator and supply power to be VCC1-1
(CP149)=5.0 ± 0.05 V.
3-2. VCC3, VCC5, VCC5-1, VCC5-2, VCC3-5, EVCC3 Voltage check
1. Preparation
• AC adaptor or voltage regulator
• Multimeter
2. Adjustment procedure
Make sure
VCC3 (CP112) = 3.3 + 0.2/–0.1 [V]
VCC3-5 (CP147) = 3.3 + 0.2/–0.1 [V]
VCC5 (CP142) = 5.5 + 0.2 [V]
VCC5-1 (CP137) = 5.0 + 0.15 [V]
VCC5-2 (CP139) = 5.0 + 0.15 [V]
EVCC3 (CP115) = 3.3 + 0.1 [V]
3. Notes
When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1
(CP149) = 5.0 ± 0.05 V.
3-3. VCC2 adjustment and VCC13, VCC7, VEE2 Voltage check
1. Preparation
• AC adaptor or voltage regulator
• Multimeter
2. Adjustment procedure
Adjust VR151 so that VCC2 (CP172) = 5.0 ± 0.02 V.
Make sure
VCC7 = 6.8 ~ 8.6 [V]
VCC13 = 11.4 ~ 14.1 [V]
VEE2 = –11.0 ~ –16.5 [V]
3. Notes
When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1
(CP149) = 5.0 ± 0.05 V.
