Progress Of Charging - Canon MV750i E Service Manual

3-2-2 Progress of Charging

When the conditions described in 3-2-1 are satisfied, the MODE MI-COM starts charging according to the specifications in Fig. 5.
The charging current in quick charge can be restricted by Compact Adapter (CA-570 / CA-570S).
* Charging is allowed to start provided that the UNREG voltage is 8.4 0.3V before
starting the charging. Otherwise, an error is indicated.
* Charging can be performed provided that the power is turned OFF.
* If the DC JACK is detected, the charging is turned OFF when the power is turned ON
(no power supplied from the battery).

quick charge starts.
* An error is indicated and charging is turned OFF if the battery voltage becomes 6.4V
or lower during charging other than trickles 1 and 2.
* An error is indicated and charging is turned OFF if the battery voltage becomes 5V
or lower during charging trickle 2.
* An error is indicated and charging is turned OFF if the charging voltage is 1.8A or higher.
* Charging is turned OFF if the charging current is 70mA or lower.
* An error is indicated if, at a start of quick charge, D terminal voltage is varied 0.15V toward
positive side or 0.3V toward negative side.
If the battery voltage
becomes
the trickle 2 starts.
