Progress Of Charging - Canon ZR70 MC A 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.2-5.
The charging current in quick charge can be restricted by CA-570.
* 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
(detected voltage > 2.7V).
* Charging is turned OFF if the charging current is 70mA or lower.
If the battery voltage

CHAPTER 2. TECHNICAL DESCRIPTION
Up to battery installed/removed
If the battery is not installed/removed
after completion of charge, charging
does not start unless the battery voltage
becomes 7V or lower.
