Novak Millennium Charger User Manual download pdf

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 (

) and up (

) 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 here

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 (

) and

down (

) 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 in

cluded

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.

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 (
