risk of dropping a metal tool onto battery. It might
spark or short-circuit battery or other electrical part
that may cause explosion.
7 Remove personal metal items such as rings,
bracelets, necklaces, and watches when working with
a lead-acid battery. A lead-acid battery can produce a
short-circuit current high enough to weld a ring or the
like to metal, causing a severe burn.
8 Only use the Chargemaster for charging the following
battery types: Lead acid, AGM, Spiral, Gel or Deep
cycle batteries. Do not use Chargemaster for charging
dry-cell batteries that are commonly used with home
appliances. These batteries may burst and cause
injury to persons and damage to property.
9 NEVER charge a frozen battery.
10 Excessive battery discharge and/or high charging
voltages can cause serious damage to batteries. Do
not exceed the recommended limits of discharge level
of your batteries.
EN / Chargemaster 12/25-3, 24-12-3 / February 2010
11 If it is necessary to remove a battery, always remove
grounded terminal from battery first. Make sure all
accessories are off, so as not to cause an arc.
12 Be sure that the area around the battery is well
ventilated while the battery is being charged. Refer to
the recommendations of the battery manufacturer.

3.1
FEATURES
In some cases however, a 2-step charging method is
more convenient. This method can be selected in the
setting mode.
With an external AC source connected, the Chargemaster
charger also serves the function of an AC to DC converter
to supply DC loads which are connected to the batteries.
The Mastervolt Chargemaster is a fully automatic battery
charger. This means that under normal circumstances it
may stay switched on with the AC power and batteries
connected. The Chargemaster is suitable for charging the
following battery types: Lead acid, AGM, Spiral, Gel or
Deep cycle batteries. It has an auto-ranging input facility
which makes it feasible to operate on almost any AC
power source in the world. It operates smoothly on both
230V as well as on 120V without any compromises for the
output current. The three-step Plus charging method
guarantees that the batteries are always charged to 100%.

3.5
THREE STEP CHARGE ALGORITHM
See figure 3. Battery charging is accomplished in three
automatic stages: BULK, ABSORPTION and FLOAT.
The first step of the three step charge system is the BULK
phase, in which the output current of the charger is 100%,
and the greater part of the capacity of the battery is rapidly
charged. The current charges the batteries and gradually
the voltage rises to the bulk voltage of 14.4V (12V models)
or 28.8V (24V models) at 25°C / 77°F.
The duration of this phase depends on the ratio of battery
to charger capacity, and the battery state of charge.

CAUTION!
The Chargemaster is not protected against:

February 2010 / Chargemaster 12/25-3, 24-12-3 / EN
OPERATION
The bulk phase is followed by the ABSORPTION phase.
Absorption charging starts when the voltage on the
batteries has reached 14.4V (12V models) / 28.8V (24V
models) at 25°C / 77°F, and ends when the battery is
completely full. Battery voltage remains constant at 14.25V
(12V models) / 28.5V (24V models) at 25°C / 77°F
throughout this stage, and the charge current depends on
the degree to which the battery was initially discharged,
the battery type, the ambient temperature, and so on. With
a wet cell battery this stage lasts approx. four hours, with
gel and AGM around three. Once the battery is 100% full,
the Chargemaster automatically switches over to the float
phase. During the FLOAT phase the Chargemaster
switches to 13.25V (12V models) or 26.5V (24V models) at
25°C / 77°F and stabilises this voltage to maintain the
batteries in an optimum condition. Connected DC-loads
are powered directly by the charger. If the load is higher
than charger capacity, the required additional power
comes from the battery, which will be progressively
discharged until the charger automatically switches back
to the bulk phase. Once consumption decreases, the
charger goes back to normal operation of the three-step
charge system.
As the Chargemaster is equipped with a three-step Plus
charge system, the batteries can also remain connected to
the Chargemaster in winter. One hour every 12 days the
charger automatically switches to absorption to keep the
battery running properly and prolong its life span. The
three-step Plus charge system is also safe for all the
connected equipment.
See
also
section
7.3
for
detailed
characteristics of the three step Plus charge
system.
3.5.1
Temperature compensated charging
By installing the battery temperature sensor (optional) the
charge voltages are automatically adapted for deviating
temperatures.
Figure 4: Temperature compensated charging
See figure 4. When the battery temperature is low, the
charge voltage increases. On the other hand, when the
battery temperature is high, the charge voltage is
decreased. Over charge and gassing are prevented this
way. This will extend the life of your batteries.
3.5.2
Connection of a second and third battery
The Chargemaster is equipped with three equal outputs.
The total output current is divided over these three
outputs. See section 4.6 for connections.
3.6
MAINTENANCE
No specific maintenance to the Chargemaster is required.
Examine your electrical installation on a regular base, at
least once a year. Defects such as loose connections,
burnt wiring etc. must be corrected immediately.
If necessary, use a soft clean cloth to clean cabinet of the
Chargemaster. Never use any liquids, acids and/or
scourers.
3.7
FAILURES
The Chargemaster is protected against overload, short
circuit, over heating and under and over voltage. If a fault
condition occurs, The Power LED illuminates red and a
load bar segment illuminates. The segment position
indicates the failure cause. See section 3.2 for
explanation.
CAUTION!
The Chargemaster is not protected against:
•
•

MASTERBUS
5 MASTERBUS
5.1
WHAT IS MASTERBUS?
All devices that are suitable for MasterBus are
marked by the MasterBus symbol.
MasterBus is a fully decentralized data network for
communication between the different Mastervolt system
devices. It is CAN-bus based which has proven itself as a
reliable bus-system in automotive applications. MasterBus
is used as power management system for all connected
devices, such as the inverter, battery charger, generator
and many more. This enables communication between the
connected devices, for instance to start the generator
when the batteries are low.
MasterBus reduces complexity of electrical systems by
using UTP patch cables. All system components are
simply chained together. Therefore each device is
equipped with two MasterBus data ports. As only a few
MasterBus cables are needed, installation and material
costs are reduced importantly. New devices can be added
to the existing network easily. Consequently the
MasterBus network is highly flexible for extended system
configuration. Mastervolt also offers several interfaces like
the Modbus interface, making even non-MasterBus
devices suitable to operate in the MasterBus network.
For central monitoring and control of the connected
devices Mastervolt offers four different panels, from the
small Mastervision compatible 120 x 65mm LCD screen
up to the full colour MasterView System panel. All
monitoring panels can be used for monitoring, control and
configuration of all connected MasterBus equipment.
CAUTION: Never connect a non-MasterBus
device to the MasterBus network directly! This
will void warranty of all MasterBus devices
connected.
5.2
Connections between the devices are made by
standard straight UTP patch cables.
OK
At least one device in the network must be MasterBus
powering (see specifications). As all powering devices
are galvanically isolated, multiple powering devices
are allowed.
OK

NETWORK
Every MasterBus device is equipped with two data ports.
When two or more devices are connected via these ports,
a local data network called the MasterBus is formed.
Keep the following rules in mind:
Place a terminating device on both network ends.
Do not make T-connections in the network.

Figure 12 shows the meaning of the event data.
Input is a pulse followed by a longer signal (1/0).
On changes the status to On at the first signal.
Off changes the status to Off at the first signal.
Copy lets the status follow the input.
Copy Invert lets the status follow the opposite of the input.
Toggle changes the status at the first signal and back at
the second signal. It is often used in combination with a
pulse switch.
