Three stage charge cycle
Battery manufacturers recommend using multi-stage charging to reduce the
stress on the battery while giving the shortest possible charge time. The
RRP-431 / RRP-432 series chargers implement the ideal charge cycle by
applying a Constant-Current charge for 70%-80% of the charge cycle and a
Constant-Voltage charge for the remaining 20%-30%. This is done to prevent
the battery from gassing as it approaches full charge, thus extending the usable
life of the battery. Once the battery has achieved it's optimal charge level, the
charger will maintain the charge using a Pulsed-Current float charge.
Thermal Compensation
In order to obtain maximum service life of the battery pack, a temperature
sensor built into the charge connector monitors the overall temperature of the
battery pack. The optimum terminal voltage for the charging process is
dependant on battery temperature. As the temperature of the battery pack
rises, the charging voltage is reduced to prevent over charge. As the
temperature falls, the charge voltage is increased to avoid under charge.
If the battery pack temperature exceeds 120 F,the charger will stop charging
the battery pack and the STATUS light will report an over temperature error.
Once the battery pack temperature falls back into the acceptable range, the
charger will resume charging the battery.
Charging Process
1. Plug in and turn on the charger. The STATUS light will flash: [MODE 2]
indicating that the unit is powered and there is no battery attached.
2. Attach the battery to be charged.
3. The unit will analyze the battery and begin the charging process indicated
by the constant illumination of the STATUS light (indicting a healthy battery)
and the constant illumination of the CHARGE light (indicating the charge
cycle is in process).
4. The battery is fully charged when the CHARGE light is no longer lit and
the STATUS light is constantly illuminated.
The CHARGE light may repeatedly briefly illuminate at the conclusion of the charge
cycle. This is normal and indicates that the charger is in the Pulse-Current float charge.
The battery is fully charged and is ready for use.
Status Mode Descriptions on Back
Do not disassemble the charger. Opening the charger will void the
warranty and can result in risk of electrical shock or fire.
Never use the charger as a DC power source for any electrical equipment.
Never operate the charger with a damaged cord or plug. Use only the
cord supplied with the charger. Inspect both input and output cords for
damage before using charger.
Never unplug a cord by pulling on the cord itself. Always grasp the plug
when disconnecting the charger.
For indoor use only. Do not expose charger to rain, snow or excessive
moisture.
Never charge a frozen battery
The battery must be placed in a well ventilated area during charging.
To reduce the risk of injury, charge only appropriate WABTEC
NextGen End-of-Train devices or 12V 5-20 Ahr RediPak / SmartPack
battery packs. Do not charge non-rechargeable batteries.

This manual contains safety and operating instructions for the RRP-433
combined charger for WABTEC NextGen ETD and Redi-Pak and SmartPack
battery packs. Before using this charger, please read all of the instructions
for both the charger and also for the battery pack to be charged.

®
1) Plug the power cord into the charger
.
2) Plug the power cord in a grounded 110/120 VAC.
3)Plug the charger lead into the ETD charging port.
Please note: The LED’s on the face plate of the charger only indicates the
charge port is operational.
The charging circuit for the ETD is built into the ETD. Refer to the charge status
display on the ETD for the battery charge status and battery information.
If the LED turns off when the charging cord is plugged into the
EOT; the EOT internal charger or EOT battery is defective.
