OPERATING INSTRUCTIONS

5.1 Introduction
The Mastervolt ChargeMaster Plus is a fully automatic battery charger. This means that under normal circumstances, it can be left switched on with AC power and batteries connected. The ChargeMaster Plus is suitable for charging of Li-ion and lead-acid batteries, which may include maintenance-free, low maintenance, AGM, gel or deep-cycle batteries. It operates on both 240V and 120V.

WARNING!
The MLI charging voltages on this charger fit the Mastervolt Li-ion (MLI) batteries but do not necessarily fit other Li-ion batteries! Always follow the instructions provided by
the battery manufacturer!
5.2 Switching on / off
The ChargeMaster Plus is activated by keeping the ON/OFF button pressed for approximately 3 seconds. The MODE LED will illuminate green. If necessary and if AC power is available, the ChargeMaster Plus will start to charge the batteries.
Note: Once switched on, the ChargeMaster Plus automatically resumes operation after it was disconnected from an AC source temporarily.
By holding the ON/OFF button pressed again for approx. In 3 seconds, the ChargeMaster Plus will switch off: the ChargeMaster Plus stops and the MODE LED illuminates red. When the ChargeMaster Plus was switched off, it can only be activated by pressing the ON/OFF button again.
WARNING!
Switching the ChargeMaster Plus off or “stand-by” does not cut off the connection to the batteries or the AC source. This means that voltages are still present inside the apparatus.

5.3 Status display
The status display at the front side of the ChargeMaster Plus enables you to control the charger and monitor the charging process.
Note: The ChargeMaster Plus can also be monitored from a remote panel like the Touch 5 (in a CZone network) or the EasyView 5 (in a MasterBus network). See section 4.2 for details.

The status display has a 3-level menu. Menu navigation is done by shortly pressing the ON/OFF button. After each press the next menu level is shown. The MODE LED color indicates the level that is being shown.

5.4 The 3-step+ charge process
Battery charging is accomplished in three automatic stages: BULK, ABSORPTION, and FLOAT. The first step 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 14.25V respectively 28.5V 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.

The BULK phase is followed by the ABSORPTION phase. Absorption charging starts when the voltage on the batteries has reached the BULK voltage and ends when the battery is completely full. Battery voltage remains constant at 14.25V/28.5V 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, and the ambient temperature, etc. With a flooded battery, this stage lasts approx. 4h, with gel and AGM around 3h. Once the battery is 100% full, the ChargeMaster Plus automatically switches over to the FLOAT phase. In FLOAT, the ChargeMaster Plus switches to a stabilized 13.25V/26.5V (Flooded), 13.8V/27.6V (Gel/AGM), or 13.5V/27V (MLI) at 25°C/77°F.
Connected DC loads are powered directly by the charger. If the load exceeds the 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 the normal operation of the 3-step charge system.
As the ChargeMaster Plus is equipped with a 3step+ charge system, the batteries can also remain connected to the ChargeMaster Plus during winter. One hour every 14 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 Figure 9 on page 31.

5.4.1 Charge voltages

5.4.2 Pre-float
The ChargeMaster Plus can automatically switch each individual output from absorption to pre float stage. Pre-float ensures batteries that are nearly full don’t receive the higher charge voltage needed in the absorption stage. This prevents over-charging, extending the lifespan of the batteries.
5.4.3 Temperature compensated charging
By installing the battery temperature sensor, the charge voltages are automatically adapted for deviating temperatures.

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. Overcharge and gassing are prevented this way. This will extend the life of your batteries.
5.4.4 Flat battery support
The ChargeMaster Plus automatically detects a flat battery and will initiate the flat battery charge curve described in the following table.

5.5 DC OUT
The ChargeMaster Plus is equipped with three full outputs; DC 1 OUT, DC 2 OUT, and DC 3 OUT. The total output current is divided over these three outputs. All batteries are charged with the same settings. See section 3.6 for connections.
5.6 Maintenance
No specific maintenance to the ChargeMaster Plus is required. Examine your electrical installation on a regular basis, at least once a year. Defects such as loose connections, damaged wiring, etc. must be corrected immediately.  If necessary, use a soft clean cloth to clean the enclosure of the ChargeMaster Plus. Do not use any liquids or corrosive substances, such as solvents, alcohol, petrol, or abrasive components.

5.7 Storage
If it is necessary to put the ChargeMaster Plus out of operation, execute the following steps:

1. Turn AC power off.
2. Switch off the ChargeMaster Plus (see section 5.2).
3. Remove the DC fuse(s) and disconnect the batteries.
4. Switch the RCD/Breaker of the AC input to the OFF position and, if required, disconnect the AC mains.
5. Open the connection compartment of the ChargeMaster Plus.
6. Check with a suitable voltage meter whether the inputs and the outputs of the ChargeMaster Plus are voltage free.
7. Disconnect all the wiring.

Now the ChargeMaster Plus can be remounted in a safe way. When not installed, store the ChargeMaster Plus in a dry and dust-free environment. To return to normal operation, after reinstallation, switch on the AC.

TROUBLESHOOTING

The ChargeMaster Plus is protected against overload, short circuit, overheating, and under and over-voltage. If a fault condition occurs, the LEDs indicate an error code. See section Status display for an explanation.
CAUTION!
The ChargeMaster Plus is not protected against serious overvoltage (>275VAC) on the AC input.
If you cannot solve a problem using the fault-finding table, contact your supplier or Advanced Systems Group. Make sure you have the part and serial number at hand.
