It is performed at the time of not operating condition (Sleep).
The content is as follows.
When not operating for a definite period of time, it performs automatically by the following change.
1. SoC (IC300) is changed into sleep mode from normal mode.
2. PWRDWN1 and PWRDWN2 of SoC signals are changed.
PWRDWN1 changes the output voltage of the Low Voltage Power Supply board (SMPS Board).
PWRDWN2 turns on/off S3.3V output by switch circuit +24VA,+24VB and S5V are also turned on/off simultaneously with it.
*Refer to Main Board Power Supply Section (P.103) and Power Supply Board Section (P.106) for details.
