Novak Millennium Charger - Manual

The Novak Millennium is a complete battery management system designed to
get the most performance out of your batteries. With its large, easy-to-read
display, the Millennium gives you vital information that is easy to comprehend.
The Millennium is equipped with Reverse Pulse Mode for all Ni-Cd cells, Linear
Mode for Ni-Cd & Sub-C size Ni-MH cells, and Ni-MH Mode for smaller Ni-MH
cells. All three modes are user-adjustable, including the charge rate, delta-peak
value, reverse pulse duration, and trickle charge rate
(even button and alarm tones).

IMPORTANT PRECAUTIONS
The following precautions will help to prevent possible damage to the
Millennium, the battery pack, or the input power source.
• Charge only nickel-cadmium or nickel-metal hydride* rechargeable battery
packs––Damage will occur from charging of any other type of batteries (lead-
acid, lithium-ion, gel cells, etc.).
*Ni-MH Mode is not intended for sub-C cells.
• Never allow water, moisture, or other foreign materials to enter Millennium.
• Do not use automobile battery chargers to power the Millennium––False
peaks can occur, and excessive voltage spikes can damage the Millennium.
• Do not obstruct the air intake on the bottom of the Millennium––This will cause
overheating and thermal shut down. Be careful if putting Millennium on a pit towel.
• Do not charge batteries with fewer than 4 or more than 8 cells–– connected in series.
• Do not charge battery packs connected in parallel––Batteries will be damaged.
• Enhanced-voltage
(“zapped”) batteries may not charge properly––Cells may be
damaged. Consult the battery matching company for charging recommendations.
• Excessive charging current can damage batteries––Maximum charging rates
for nickel-cadmium and nickel-metal hydride can be obtained from battery maker.
• Never exceed 15 volts DC input power source to power the Millennium.
• Gases from a lead-acid battery may ignite if sparks occur when connecting
or disconnecting the Millennium’s alligator clips––Using a lead-acid battery as
a power source may generate hydrogen gas and should only be used in a well
ventilated area. Avoid open flames and sparks which may ignite battery gases.
PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY
INPUT POWER SOURCE VOLTAGE
As a general rule, the input power source voltage should be 1.5 volts DC above
the peak-voltage of the battery pack being charged.
Example 1: (6 cell Ni-Cd pack peak-voltage
≈ 10.5 volts) + (1.5 volts) = 12 voltsDC
Example 2: (8 cell transmitter pack peak-voltage ≈ 13.5 volts) + (1.5 volts) = 15 voltsDC
Remember that older battery packs peak at higher voltages.
If your power supply’s output voltage does not adjust high enough to peak the
battery pack as described above, 8 cell packs can be charged as two, 4 cell packs.
MILLENNIUM CONTROLS & DISPLAY
Your Millennium is designed to be very easy to operate and understand.
On the angled front panel of the Millennium you will find everything you
need to be in total control of your battery management. The Millennium’s
main advantage is its large LCD with electronically-adjustable viewing
angle. This LCD gives you easy to follow prompts, and guides you through
all of the Millennium’s adjustments and controls.
The sections of this manual
are the same as the LCD screens you will go through on the Millennium.

The viewing angle adjustment pot lets you adjust the Millennium’s LCD
contrast with a flat blade screwdriver for different positions and lighting.
The down (B) and up (C) buttons navigate you through the SELECT MENU
screens, and are used to modify various parameters. The ENTER button is
used to make selections from the SELECT MENU screens, enter a value for
the various parameters, or begin charging. The BACK button returns you
to the previous screen once past the SELECT MENU screens.
The first level of navigation in the Millennium’s
software is the SELECT MENU option screens. The
loop of first level option screens is shown hereR
In each of the SELECT MENU screens (and CHARGE
MODE screens), the top line of the LCD displays
your present location in the software (SELECT
MENU or CHARGE MODE), and shows up (C) and
down (B) arrows to prompt you to use one of
these keys to continue navigation.
The bottom line of the LCD displays one of the
software options. You can go to the second level
of the Millennium’s software by simply pushing
the ENTER button at any of the option screens.
The Start option begins the charge process. The
other options take you to the next software level
where you can change various parameters.

INPUT POWER SOURCE CONNECTION
The Millennium’s input power connection can be found in the lower
corner of the back panel of the case. The supplied power harness has a
matching connector attached to it, and will plug directly to the panel-
mounted connector on the back of the Millennium case.
When looking at the panel-mounted connector on the back of the case,
the lower pin is negative (–), and upper pin is the positive (+) connection
and is marked with a raised rib in the plastic connector as shown below.

Acceptable Input Power Sources: DC power supply or lead-acid battery
*Output current of power source should meet/exceed desired charge rate.
**Connect input power harness to lead-acid battery before connecting harness to Millennium.
If the Millennium will be used with a power supply, cut the wires of the
input power harness included with the Millennium to the desired length
and secure them to the output terminal screws of the power supply.
If your power supply has post-style output terminals, or if you will be
running the Millennium from a lead-acid battery, you can solder the included
alligator clips to the input power harness. Solder the red alligator clip to
the wire that goes to the Millennium’s positive (+) upper pin (ribbed).
Solder the black alligator clip to the wire from the negative (–) lower pin.

From the Start screen, push the up (C) button three times to go to the
Volt Threshold option screen, or once more from the Button Tone screen.
The Volt Threshold value entered is the drop in millivolts that the
Millennium looks for to determine that the battery pack has peaked. This
is adjustable from 4 to 20 mV/cell (refer to Tips & Rec. Settings Section).
To adjust, push the ENTER button from the Volt Threshold option screen.
You can now use the down (B) and up (C) buttons to change the value.
