DESCRIPTION OF OPERATION
General
The PTO™MOD3 series of chargers are compatible with batteries at 24, 36, 48 volts or 72, 80 volts,
depending on model.
PTO™MOD3 chargers are microprocessor-controlled. The processor calculates the battery’s
capacity so that the charging profile can be automatically adapted to the battery’s actual state over
a wide range of capacities. The charging coefficient is maintained absolutely on all types of batteries.
PTO™MOD3 chargers adapt to the battery’s capacity and its discharge level.
PTO™MOD3 chargers can easily be set to charge flooded batteries used in cold or freezer storage
applications, standard flooded or opportunity profiles. This battery charger is also designed to charge
flooded and sealed lead-acid storage batteries within the range of the cell and amp-hour rating as
marked on the nameplate.
Auto Start Charge
When a battery is connected to the charger, the control board senses the voltage and after a 20
second delay, the charger starts charging the battery automatically.
Charging Current
Charging current is determined by the charger based on battery voltage and its state of charge.
Charging current declines automatically as battery voltage rises during the charge. As the battery
charges, the graphical LCD display will output various charge parameters including the charging
current.
AC Power Fail
If the AC power fails while the battery is connected to the charger during a charge cycle, the charger
will reset and start a new charge cycle when power is restored. All charger settings as well as the
time and date are preserved.
Series Charging
In series charging, the voltages of both batteries add up and must match charger’s nameplate DC
Volts rating. The charger’s amp-hour rating must be equal to each of the batteries’ AH rating. Charge
cycle will not start unless both batteries are connected.

GLOSSARY
Charge Blockout
This function prevents the charger from charging the battery during the block out time window. If a charge
cycle has started before the block out window it is inhibited during the block out window and will automatically
restart the charge cycle at the end of the block out window.
Charging Profile
The charging profile defines the rate of current charge over time. The charger adapts to the battery’s condition
and level of discharge.
Cold Profile
This is a charging profile that allows the configuration of the charger for use with batteries in cold storage
application. The profile is an IEI (constant current, constant voltage, constant current) type with a number of
user configurable parameters.
Thin Plate Pure Lead (TPPL)
This is an advanced lead acid battery design used in FLEX batteries. TPPL technology provides longer
service life, higher power density, longer shelf life and fast recharge capabilities.
Flex Bloc Profile
This charging profile allows charging of Flex bloc batteries at rates up to 0.7C.
Flex Standard Profile
This charging profile allows charging of FLEX 2v cell batteries at rates up to 0.25C.
Equalization Charging
Equalization charging, performed after normal charging, balances the electrolyte densities in the battery’s
cells.
Opportunity Profile
The OPPOR charge profile is used when opportunity charging is desired. It has a start rate of 25% of the
batteries rated amp hour capacity, requires one complete recharge in every 24 hours of service and must
have an equalize charge done once a week which is programmed to run automatically.
Operation:
During opportunity charging the user can plug the battery in and charge it during breaks, lunch or any
work stoppage time. One time per day the battery must receive a full standard recharge. The complete
charge must be programmed for a delay that’s long enough so that the complete charge will not occur
during normal operation. Sufficient time should be scheduled after the full charge to allow the battery
to completely cool to ambient temperatures before use.
Note: The user must configure the charger for the day of the week that the equalize charge will take
place.
Standard Flooded
The profile is an IEI (constant current, constant voltage, constant current) type with a number of user
configurable parameters.
Refresh Charging
Refresh or maintenance charging enables the battery to be maintained at maximum charge all the time that
it is connected to the charger. Refresh charge is applied at a predetermined intervals after charge is complete
and battery remains connected to charger.
