OPERATION
Self-Test: Upon applying mains power, each TWQ will initiate a self-test
mode. This mode is indicated by the LED’s on the unit. Each position
will light the red LED followed by the green LED. Upon completion of
the self-test, the green status light will light steadily, indicating that the
unit is ready for operation.
Charging: As with all Anton/Bauer chargers, charging with TWQ
is fully automatic. Mount any applicable battery to any open Gold
Mount position on the charger and it will automatically determine the
appropriate charge routine and execute it.
Applications: The TWQ models will charge any combination of Anton/
Bauer Logic Series®Gold Mount®batteries including models: ProPac®
14, Trimpac®14, ProFormer®, Digital ProPac®14, Digital Trimpac®14,
HyTRON®and Dionic®batteries.
Each TWQ incorporates the exclusive Anton/Bauer InterActive®
communication between battery and charger, which allows the charger
to identify any Anton/Bauer battery attached and determine the precise
charge routine for that battery under the prevailing conditions.
This information is communicated to the charger by the battery and
is incorporated, through specialized programming and algorithms to
optimize the charging of the DIGITAL battery.
IMPORTANT: Due to the specialized communications between
the charger and the battery, batteries without the
Logic Series®construction and communication
capability (manufactured by Anton/Bauer before
1989 as well as so-called “rebuilds”) can not be
charged with this TWQ. The InterActive®
communication of Logic Series®batteries is the
key which allows the TWQ to safely identify and
address new style and chemistry batteries as they
are developed. Moreover, this communication
ensures that batteries contain the quality cells,
workmanship and safety of genuine Anton/Bauer
products. If non-Logic Series®batteries are placed
on the TWQ, the red and green LED indicators will
ash alternately. This indication means that the
battery cannot communicate its identity to the TWQ
and is not charging.
THREE STAGE CHARGING METHODOLOGY
In general, the TM4 will deliver a three stage charge routine to each
battery.
1. STAGE ONE will deliver a high rate charge matched to the
capabilities of the battery (typically a one or two hour rate, depending
on battery type). During this stage, seven separate cutoff methods
are in operation, simultaneously, ensuring the fastest, safest charge
for that battery:
TCO - Temperature cutoff which stops the Stage one charge precisely
when a temperature indicative of full charge is reached;
Dt/dT - A microprocessor based algorithm which measures
a rise in temperature over a specic time, very accurately
indicating full charge. This method is also the recommended
method for charging Ni-MH technology;
∆V - A method to determine the end of stage one charging by
identifying a characteristic “reverse slope” of a Ni-Cd cell. Since
this characteristic can be disguised by the age, temperature and
the number of the cells in a battery, it can never be employed
alone;
CCO - This method requires the identication of the particular
battery size (capacity) and chemistry, an exclusive Anton/Bauer
Logic Series feature. The charger determines the maximum
to ensure that overcharge conditions are avoided.
FUL - This determination is made when a fully charged DIGITAL
battery is returned to a charger within specied parameters of
time, temperature, and battery voltage. The DIGITAL battery
communicatesitsfullychargedconditionandthechargerconrms
the parameters and immediately indicates a fully charged condition,
withoutadditionalverication.
TEMPERATURE COMPENSATED VCO – For HyTRON™series
of batteries. Similar to a VCO, however, only operates within
certain temperature parameters.
I-Min – For Dionic®batteries, a seventh cutoff method is employed.

2. STAGE TWO charging is a BALANCING or “stabilizing” mode
which calculates each battery pack type to offset any imbalance
of the battery’s cells, created by unequal self discharge or any
capacity mismatch of the individual cells in the pack. This stage
can vary in duration from zero to as much as 16 hours, depending
on the condition of the battery. The Stage Two charge for DIONIC®
batteries reduces current automatically as the battery charges
maintaining the lithium ion cells at a safe voltage level. A battery
will typically leave Stage Two in 2-4 hours under average operating
conditions.
3. STAGE THREE charging is the Anton/Bauer exclusive Lifesaver®
maintenance mode. This patented pulse routine keeps batteries fully
charged,freefromself-discharge-indenitely-withoutdamagingheat
associated with a so-called “trickle charge”.
NOTE: Anton/Bauer strongly recommends that batteries are kept on
the TWQ until ready for use. The Lifesaver®mode will keep
them 100% charged and ready for use.
