Cleaning - AEMC DTR 8510 User Manual

Functionality:
Charging begins when the charger is connected to the DTR
power switch is in the OFF position. The LED will be orange before the
fast charge starts. The LED will change to red when the fast charge cycle
begins. When the cells are fully charged and the voltage drops (because
of the -dV signal from the cells), the charger will go into a top-off charge
mode before switching to trickle charge mode.
During the top-off charge session, the LED will be green with short, inter-
mittent orange flashes. When the top-off charge is complete, the charger
will go into trickle charge mode, changing the LED color to green. The
charge current is now reduced to a safe level. However, trickle charging in
excess of 12 hours on routine basis could be damaging for NiMH batteries.
If the safety timer disconnects before -dV, the top-off charge will not be
engaged. The charger will then go directly to trickle charge mode and the
LED will turn green. If the battery voltage is far below normal, the charger
will stop the fast charge current and switch to trickle charge mode. The
LED will then indicate an "error" by flickering green and red. The battery
packs and/or the charger may need to be replaced.
If the line power is turned off, the charger will reset and start a new charge
cycle when it is turned on again.
