WAKE-UP CIRCUIT

When the lithium-ion battery pack is needed to provide
battery voltage (get out of Sleep Mode, see Sleep
Mode), the wake-up circuit sends a signal to the
battery pack to wake-up.
When the wake-up signal has been received, the
battery will then reactivate battery voltage at the

WARNING
DO NOT use batteries types that are not approved
for the charger or improper mode settings.
Damage to the batteries or charger may occur if
the mode setting is not correct for the type of
batteries being used. If the battery manufacturer of
the battery you are using is not listed, contact
Service Engineering
Management System.
NOTE: Mode settings can be checked by connecting
the battery charger to a 120V AC power source, while
connected to the battery, and watching the LED
display. See charger manual for details in diagnosing
charger LED flashes if the LEDs do not flash when
initially connected to power.

terminals, which then powers the electrical system.
The battery system will remain active until another
sleep mode timeout occurs.
The wake-up circuit does not require special operation;
turning the key switch to "ON" will trigger the battery's
wake-up circuit.
The battery pack wake-up circuit is activated when
signal B(-) ground is provided. The pack will not wake-
up if:
• The signal line is low
The battery pack requires charging
•
• Battery pack is outside its operational limits
An internal fault has occurred
•
Refer to Figure 6 for wake-up circuit information.
NOTE: If the battery manufacturer of the battery you
are using is not listed, contact Service Engineering
through the Contact Management System.
The battery charger has 16 mode settings. The proper
mode setting is determined by the type of batteries
being used in the battery pack. The Lithium-Ion battery
should be set to Mode 15. Note that batteries must be
uniform in brand and model. Do not mix different
battery sizes, construction types, or old batteries with
new batteries. See Figure 5.
For chargers manufactured after May, 2013, the mode
key has been replaced with a dip switch, see Figure 4.
NOTE: Chargers can be identified by the MFR MOD
number on the charger label. If the first two digits of
the MFR MOD number read 1Q or 2Q, the equipment
is a Gen IV Q-Series charger.
