Trinity DPD User manual
Your new DPD Discharger was designed to discharge and
condition your battery packs and keep their performance at
the highest level for the longest number of cycles. Both Ni-
Cd & Ni-MH battery packs can be discharged in side x side
(in tray) or stick pack conguration (with external leads).
The external function works great for discharging your
Speed Spec™ packs and Dyna Pulsing them for better
performance.
The DPD also employs a 5 amp linear or 30 amp Dyna
Pulse™ discharge mode. Read more information on Dyna
Pulse discharging at the end of the instructions.
The DPD uses menu driven software for all discharging
functions. It will be displayed on the easy to read LCD
screen and is fairly simply to use. We programmed the
DPD with settings that are actually usable for the serious
racer.
Read the instructions and become familiar with the
functions before using. You will nd the DPD the best tool
you ever bought for taking care of your R/C battery packs.
GETTING STARTED:
The DPD functions on 2 AA batteries not included. On the
back of the unit simply remove the battery door, install two
AA batteries (spring is negative), reinstall the door and
the unit is ready to function. No external power source is
needed!
LEARNING THE BUTTONS:
1. Left Button: Power on and off.
2. Red Light: Warning, malfunction, end of discharge.
3. Upper Right Button: Scroll up.
4. Middle Right Button: Select.
5. Lower Right Button: Scroll down.
6. Levers: Up for installation of battery pack, levers pushed
forward or down to lock.
7. External Wires: For discharging an external battery as
one unit. You cannot discharge two batteries at one time
or ever connect the external wires to an internal pack while
the unit is in operation!
The DPD runs off 2 “AA”
batteries so no power
supply is needed.
BATTERY CONFIGURATION:
There are six cell slots, from left to right. Slot one is for cell
one, slot six is for cell six when looking at the data.
It is important that for six cell use, your positive connection
tab is lower right.
In four cell mode the positive connection tab is lower right
in cell slot four.
If the battery is installed incorrectly you will receive a
warning sound and the warning light with ash until the
problem is corrected. Any time during the use of this
discharger, if the warning sounds and light ashes it
will stop functioning until the problem is corrected. If the
problem cannot be corrected turn the unit off and start over.
This is a fail safe measure.
DISCHARGING:
To power up the DPD, push the start button once. The
welcome screen will appear followed by the main menu.
You will have three options:
1: Linear: Select this to discharge at a 5 amp constant
discharge rate.
2: Pulse: Select this to discharge at a 30 amp Dyna Pulse
rate. This mode is used for conditioning your battery pack
after you are through racing for the day.
3: Last Data: Select this for viewing the previous discharge
data. Only the last discharge can be displayed. They are
not saved. The previous results are viewable until you start
the next discharge. Even if the unit is powered down you
can still access them.
After selecting the linear or pulse discharge mode the menu
will ask if you want to discharge an internal pack or external
pack. Choose internal for a side x side battery pack and
external for a stick battery pack. Push mode to select the
type battery you are using.
Internal Select:
After you choose internal select, it will ask you for the
cutoff voltage. It is defaulted at .90 per cell. This is what
we recommend for the IB 4200, Intellect 4200 GP4300 and
most of the high end Ni-MH batteries being used. You can
change this by pushing the scroll buttons.
After selecting your cutoff voltage press mode and the
DPD will check the connections and the unit will start
discharging.
External Select:
After selecting your discharge mode the unit will again
display options. This time scroll down to external pack.
Connect the battery using the two external wires, Red+
Black-.
Remember you can not install the pack in the unit and
attempt to discharge using external wires! External means
out of the battery cradle and out side of the unit!
Now that you have selected external pack, the unit will ask
how many cells are in the pack. You can select 4-9 cells.
Make your selection by pushing the mode button. The unit
will then ask for voltage cutoff. Again it is defaulted to .90
per cell. It will calculate .90 X 6 cells for a nal pack cut-off
at 5.40 volts. Press mode again to start. The DPD will start
the discharge process.
DISPLAY:
While discharging the DPD will display the voltage of each
cell as it discharges. After each discharge cycle, the nal
results will be displayed on the LCD Screen. First the entire
pack averages will be shown and then it will be followed by
each individual cell result (internal only).
TROUBLE SHOOTING:
If your battery pack is incorrectly installed polarity wise or
not in contact with contact pins the alarm will sound and
red light will ash. The same thing will also happen if the
battery pack has a bad solder connection or bad cell. The
Display will prompt you to check battery pack.
Press mode to restart and if that does not work try
removing battery and replacing it in the tray to make sure it
is making a good connection with the contacts.
You must wait 5 seconds before you can restart the unit.
MISC:
At any time you can toggle on the backlight by pushing
a scroll key. The light automatically shuts off when the
process starts.
DYNA PULSE:
The Dyna Pulse mode uses a Dynamic Pulse™ discharge
which removes crystal build up inside the cell resulting in
higher voltage and capacity. Use of the Dyna Pulse mode
will prolong the high performance life of the battery pack
and increase voltage output.
The Dyna Pulse mode discharges in 30 amp blocks
followed by a cooling-down period. This prevents a heat
cycle during the discharge process but provides the high
amp rate discharge needed for serious racing.
Discharging a fully charged battery can take more than two
hours due to the Dynamic Pulse technology. This is the
only way your batteries have enough time to dissipate all
the energy and prevent a heat cycle.
RACING TIPS:
Always immediately stop racing when your battery goes
at. If you keep racing too long, you might damage your
battery.
After racing for the day, connect the DPD and Dyna Pulse
discharge as soon as possible. This will give the best
results for the next race day.
Charge and Discharge your battery again just before
charging it for racing. Top racers do this. The pack will
accept more energy when doing this and voltage will be
higher.
DPD is not intended for use by children under the age of
14.
Speci cations may change due to ongoing research and
development.
