the bottom of the enclosure to your central ground (vehicle chassis, grounding system of

your boat etc.)

!

CAUTION

Always connect the negative (-) cable directly on the negative terminal of the battery, or on

the “loadside” of a current shunt. Always keep positive and negative cables close to each

other to minimize electromagnetic fields. Double check for correct polarity, before

connecting the battery cables to the battery! Wrong polarity may damage the charger.

10

!

CAUTION

Please feed all connection compartment wiring through the rubber grommets and plastic

gland.

2.4.1 Control board connections and settings

The following image shows the control board connections and switch options.

① Master/slave switch position. This switch must be set to ‘MASTER’ when a single

charger is installed. The ‘SLAVE’ setting is only relevant for parallel charger systems.

② 5 pole screw terminal block. The first three positions are connected to the ‘normally

open’, ‘normally closed’ and ‘common’ contacts of the internal alarm relay. This relay

will be activated when the charger shuts down into an error mode. When the error

condition has been cleared, this relay will de-activate again. Please make sure not to

exceed the maximum relay contact rating of 60V and 5A to avoid damaging the relay

or PCB.

On the 4th and 5th position of the screw terminal, an external switch can be connected

to remotely turn the charger on and off. This switch can be located up to 50 meters

away from the charger. It is advised to use a wire size of 1mm2 (AWG17) for the

remote switch connection. For the remote switch, any single pole switch can be used.

Only a low power signal must be switched on this line.

③ Remote bypass switch position. When a remote switch is connected to the 5 pole

screw terminal block, the remote bypass switch must be set to OFF. When no remote

switch is used, the remote bypass switch must be set to ON.

11

2.4.2 Bottom side connections

Please see the next image for the bottom side connections.

2.5 Parallel operation

Up to 6 battery chargers of the same model can be connected in parallel, in order to reach

very high charge current levels. This manual will not show any connection or operation

details for paralleled charger systems. Such details are explained in the documentation that

is included with the optional “Omnicharge XL Parallel Kit (art.# 5029950)”.

3. CONFIGURING THE BATTERY CHARGER

3.1 Selecting the correct charge program

The image in chapter 2.4 showed the location of the rotary selector, which is used to select

the desired charge program. The charge program selection depends on the type of battery

that needs to be charged. Each battery type has its own typical bulk and float charge

voltages. When your battery type or optimal charging voltages are still not available in the

standard list, you can select rotary position ‘0’ and setup the battery charger using the TBS

Dashboard for Windows software. This software is included in the optional TBSLink to USB

Communication Kit (art.# 5092120), which also contains an isolated interface box required to

connect the Omnicharge to a PC. Using TBS Dashboard, all available parameters can be

edited, and it is also possible to edit or create your own battery charge programs.

!

CAUTION

Invalid battery type settings can cause serious damage to your batteries and/or connected

battery loads. Always consult your battery’s documentation for the correct charge voltage

settings.

In de following table, all settings are explained.

3.2 Charge programs explained

Most standard selectable charge programs, perform a four stage IUoUoP charging process

comprising of a “Bulk” , an “Absorption”, a “Float” and a “Pulse” stage. The image below

visualizes the four stage charging process (for typical 48V voltage values, please multiply the

24V values by 2):

In the Bulk stage, the charger delivers full output current and typically returns approximately

80% of charge back into the battery once the absorption voltage is reached. During this

stage, indicators 3d and 3c (see frontpanel image in chapter 4.1) will be lit depending on the

Bulk charge progress.

When the absorption voltage has been reached, the Absorption stage will be entered and

indicator 3b will be lit. This stage will return the final 20% of charge to the battery. The

output voltage is kept at a constant level and the charge current decreases as a function of

the battery's state of charge. When the charge current has dropped below a certain value or

when the maximum absorption timer has been expired, the Float stage will be entered.

Indicator 3a will be lit and an acoustical message will sound, indicating that the battery is

full. In this stage the battery voltage will be held constant at a safe level for the battery. It

will maintain the battery in optimal condition for as long as the battery remains connected

to the activated charger. Connected battery loads will be directly powered by the charger

up to the charger's maximum output current level. When even more current is drawn, the

15

battery must supply this which results in a declining battery voltage. At a certain battery

voltage level, the charger jumps back to the Bulk stage and will finalize a complete four stage

charging process again, once the battery load consumption has dropped below the charger's

maximum output current level.

The fourth stage called “Pulse”, will perform a short refresh charge of approximately 1 hour

each 7 days while the charger operates in the Float stage. This will keep the battery in

optimal condition while prolonging it's lifetime. The battery can remain connected to the

activated charger continuously, without risk of overcharging.

When the battery temperature sensor is installed, the charger automatically compensates

the charge voltages against battery temperature. This means that the charge voltages are

slightly increased at lower temperatures and decreased at higher temperatures (-30mV/°C

for 12V chargers, -60mV/°C for 24V chargers and -120mV/°C for 48V chargers). This way,

overcharging is prevented which prolongs your battery's lifetime. A connected battery

temperature sensor also enables the battery temperature protection, which stops the

charging process when the battery's temperature is below -20°C or above +50°C.

4. GENERAL OPERATION

4.1 Omnicharge display and control overview

See the next image for an overview of all LED indicators on the Omnicharge frontpanel, as

well as the location of the main switch.

The frontpanel can be divided into four sections :

① Output current bar. Indicates the percentage of total delivered charging current.

② Mode indicator. Indicates the operating mode of the battery charger

Indicator mode

Description

Continuous green

Power on, normal mode

Flashing red (1 flash per sec.)

Battery error

A battery error can appear for several reasons. These are :

battery voltage is too low (too deeply discharged) or too

high and battery temperature is too low or too high (only

available when battery temperature sensor is connected).

The charger will not restart automatically in battery error

mode, except when this error was generated due to a too

low battery voltage or a too low battery temperature.

Flashing red (2 flashes per sec.)

High/low AC input voltage

17

Flashing red (3 flashes per sec.)

High charger temperature

The charger automatically restarts when the temperature

is below an acceptable level.

Flashing red (4 flashes per sec.)

Charger error (return for service)

③ Charge status bar. Gives a rough indication of the charging progress, see below :

LED 3a : 100% full (ready)

LED 3b : 80% full

LED 3c : 50% full

LED 3d : empty

④ Power on, off, charger only switch.

Switch position

Description

“0”

Charger off

When the switch is in position “0”, it does not interrupt

any internal AC or DC sources. This means that there are

still lethal voltages present inside the charger! In position

“0”, the charger will still consume a small amount of AC

current.

“I”

Charger on in automatic charging mode

“II”

Charger on in forced float mode

In this mode, the output voltage of the charger is set

constantly to the float voltage (value is depending on

selected battery type) while being able to deliver full

rated output current. Since no automatic charging

programs are activated in this mode, it can be used for

constant voltage charging or operating the charger as a

battery buffered power supply.

4.2 Charging batteries

!

CAUTION

Before you start to charge batteries, read all enclosed safety instructions and warnings

while following all safety precautions about working with batteries.

The list below globally describes the steps to follow for charging batteries :

1. Push the charger switch in the “O” (Off) position and disconnect the AC supply to the

charger

2. If possible disconnect or switch off all loads from the battery

3. Connect the battery to the charger

4. Switch on the AC supply and activate the charger by pushing the charger switch in the

“I” (power on) position. After a two tone beep, the charger will start the charging proces.

5. After charging is completed, push the charger switch in position “O” and switch off the

AC supply again, before disconnecting the battery. Or, keep all connections and the

charger switch position untouched and just re-connect all battery loads.

18

4.3 Equalizing a flooded battery

If you are using a lead acid battery, an occasional equalization charge cycle may

be recommended by the manufacturer. This might also be true when the battery

has been very deeply discharged or often charged inadequately. During equalization, the

battery will be charged up to approx. 15.5V (31V for 24V and 62V for 48V models) at a

reduced output current level. Before starting an equalization charge cycle, the following

caution statements must be read carefully :

!

CAUTION

Equalization should only be performed on a lead acid battery type that supports this

process. Therefore the Omnicharge only allows equalization when the battery type rotary

selector is set to Flooded, AGM or Lead Calcium. Other battery types like GEL or Lithium will

be damaged by this process. Please be aware that not all AGM and Lead Calcium battery

manufacturers allow an equalization process. Always follow the battery manufacturer's

instructions when equalizing batteries.

During equalization, the battery generates explosive gasses. Follow all the battery safety

precautions enclosed with your Omnicharge. Ventilate the area around the battery

sufficiently and ensure that there are no sources of flames or sparks in the vicinity.

Disconnect all loads connected to the battery during equalization. The voltage applied to

the battery during this process may be above safe levels for some loads.

The Omnicharge cannot automatically determine when to stop the equalization of a

battery. The user must monitor the battery’s specific gravity throughout this process to

determine the end of the equalization cycle. The internal 1 hours time-out timer of your

charger is only intended as a safety feature, but may not be sufficiently short to prevent

battery damage. Therefore, equalizing a battery is always a process that must continuously

be supervised by the user.

As explained earlier, the Omnicharge will only allow equalization when the battery type

rotary selector is set to a battery type that may allow an equalization cycle. Besides this, the

charger also needs to have a full charge cycle completed and must operate in the Float

stage. When these two conditions are met, the equalization charge mode can be activated

by pressing the recessed pushbutton on the bottom side of the unit (see image in chapter

2.4.2) for 3 seconds, until all charge status indicators start flashing.

The Omnicharge battery charger will allow a maximum equalization time of 1 hour before it

automatically jumps back to the Float stage. If the specific gravity of each cell does not

match the battery manufacturer's specifications yet, you can initiate a new 1 hour

equalization cycle by pressing the pushbutton for 3 seconds again. Always keep on checking

the specific gravity of each cell repeatedly during the equalization process. When these

values are correct, you can manually exit the equalization process by pressing the recessed

pushbutton once. The battery charger will then return to the Float stage.

19
