SERVICES BATTERY CHARGER:
On board of your yacht there are two fully automatic battery charger and high efficiency. They feature an optimized charge technique to charge batteries quickly and safely, while feeding the connected uses. In addition, they are protected against short circuits, overload and high temperatures (engine room).
On the front side of the chargers, a capacity gauge gives you some information on the residual capacity of the batteries, like the fuel level gauge of a car. More LEDs are ON, more the battery is charged.
Energisation
The battery charger is energized when the switch (8) is in the ON position. One of the LEDs on the front side turns ON and the charge starts immediately.
De-energisation
The battery charger is de-energised when the switch (8) is set to OFF.
The connection between the electric mains and the battery charger is not interrupted with the switch.
Bulk (LED 1 ON)
The battery is discharged only when the first LED Bulk/ON (Quick charge/ ON) is ON. Now the battery charger provides full power and the battery voltage increases slowly. After having reached the 27.6V level, the battery is about 25% charged and the second LED turns ON.
(LEDs 1 and 2 ON)
The battery has been charged to 25%. The battery charger still provides the maximum output current and voltage increases up to the level of absorption voltage. Phase A can last up to 6 hours max.
Absorption (LEDs 1, 2 and 3 ON)
The battery has been charged to 50%. The battery charger limits the charging voltage to a safe level and the charging current decreases slowly.
(LEDs 1 to 4 ON)
The battery has been charged to 75%. The charging voltage is limited to the absorption level, because the battery is nearly full. Current consumption will continue decreasing.
Maintenance (LEDs 1 to 5 ON)
When all the LEDs are ON, the battery is fully charged.
The slow maintenance/charging programme provides a output voltage, high enough to keep the batteries with a 100% charge, but low enough to prevent that the batteries suffer unnecessary constraints. The battery charger can now deliver full power to the connected uses/loads.
| LEDs ON | Meaning |
| Normal operation: the green light of LED no. 6 turns ON | |
| 1 | Battery charger ON |
| 1+2 | U output > 27.6V |
| 1+2+3 | U output = absorption (28.5V) |
| 1+2+3+4 | 3 hours after the max. bulk time has started or I < return amp |
| 1+2+3+4+5 | 6 hours after the max. bulk time has started or I < return amp. for 15 min or more |
| 9 | Recharging current equal to 0-5% of total current |
| 9+10 | Recharging current equal to 5-25% of total current |
| 9+10+11 | Recharging current equal to 25-50% of total current |
| 9+10+11+12 | Recharging current equal to 50-75% of total current |
| 9+10+11+12+13 | Recharging current equal to 75-100% of total current |
| 6 | Green: normal operation, red: faulty, OFF: stand-by or OFF |
| 7 | Green: communication of MasterBus in progress, OFF: no communication of MasterBus |
| Failure condition: the red light of LED no. 6 turns ON | |
| 6 red +1 | Battery detection error |
| 6 red +2 | Too high temperature of the battery charger |
| 6 red +3 | Short-circuit warning: the battery charger will reduce charging current to 25% |
| 6 red +4 | CC error: CC voltage is too low or too high |
| 6 red +5 | Temperature detection error |

CAUTIONThe connection between the electrical mains and the battery charger is not interrupted with the commutator.
ENGINES BATTERY CHARGER:
Your yacht is equipped with an onboard engines battery charger.
The Chargemaster is a fully automatic battery charger.
This means that under normal conditions it can remain switched on with AC power and batteries connected. It has an automatic input device that allows operation with virtually any available AC power source. The three-step charging method ensures that the batteries are always 100% charged.
With an external AC source connected, the charger also functions as an AC/DC converter to supply DC loads connected to the batteries.
The battery charger can be activated by keeping the POWER switch pressed for about 3 seconds.
The POWER switch will start blinking green and the charging status will be displayed. If necessary and if AC power is provided, the battery charger will start charging the batteries.
In the event that the charger is in standby or the AC power supply is interrupted, the POWER switch starts flashing red. After about two minutes, it stops flashing and the display turns off, thus preventing the battery from charging by the indicator light.
For further information on use and maintenance, please refer to the manufacturer’s manual.
GENERATOR BATTERY CHARGERS:
Your yacht is equipped with two onboard generator battery chargers.
For further information on use and maintenance, please refer to the manufacturer’s manual.
