KAVAN C20 Duo - Návod k obsluze
ÚVOD
Blahopřejeme vám k zakoupení dvoukanálového síťového nabíječe/vybíječe s balancerem KAVAN C20 Duo. Zařízení má jednoduchou obsluhu, ale používání nabíječe a správné zacházení s akumulátory vyžaduje určité znalosti, které si uživatel musí osvojit. Je proto naprosto nezbytné, abyste se s návodem a v něm uvedenými zásadami bezpečného provozu v úplnosti seznámili dříve, než nabíječ poprvé zapojíte.

ZÁSADY BEZPEČNÉHO PROVOZU
- Během nabíjení/vybíjení neponechávejte akumulátory nikdy bez dohledu, zkrat nebo náhodné přebití (akumulátoru nevhodného pro rychlonabíjení nebo nabíjeného nadměrným proudem) může způsobit únik agresivních chemikálií, explozi nebo požár.
- Během nabíjení dotekem kontrolujte teplotu akumulátoru - ke konci nabíjení se může mírně zahřát (okolo 40°C, ale nesmí být horký – v tom případě nabíjení ihned přerušte a odpojte akumulátor od nabíječe).
- NEPOKOUŠEJTE se nabíjet jiné typy akumulátorů nebo baterií, než pro které je tento nabíječ určen – pouze niklkadmiové, niklmetalhydridové, lithiumpolymerové (LiPo a LiHV), lithiumiontové, lithiumfosfátové (LiFePO4) a gelové olověné akumulátory s počty článků dle specifikace v tomto návodu.
- Nikdy se nepokoušejte nabíjet/vybíjet následující typy akumulátorů nebo baterií:
* Akumulátorové sady sestávající z článků různých typů (nebo různých značek). * Primární (suché) baterie. * Akumulátory, které vyžadují jiný způsob nabíjení než LiPo, LiIon, LiFe, LiHV, NiMH, NiCd, Pb. * Vadné nebo poškozené akumulátory. * Akumulátory vybavené vestavěným nabíjecím nebo ochranným obvodem. * Akumulátory instalované v nějakém zařízení nebo elektricky s jiným zařízením propojené. * Akumulátory, které nejsou výrobcem výslovně určeny pro rychlonabíjení.
- Nepokoušejte se nabíjet akumulátory velkým proudem neúměrným typu nebo kapacitě akumulátoru. Při volbě nabíjecího proudu se vždy řiďte údaji doporučovanými výrobcem akumulátorů.
- Zabraňte proniknutí vody, vlhkosti nebo cizích předmětů dovnitř nabíječe.
- Povolené síťové napájecí napětí je 100-240 V/50-60 Hz nebo stejnosměrné 11-18 V (autobaterie). Nabíječ se nepokoušejte napájet současně ze sítě a z autobaterie.
- Nabíječ umisťujte na pevný, rovný a nehořlavý povrch.
- Nabíječ a nabíjený akumulátor neumisťujte při nabíjení na nebo do blízkosti hořlavých předmětů. Pozor na záclony, koberce, ubrusy atd.
- Nezakrývejte chladící otvory na skříňce nabíječe – mohlo by dojít k jeho poškození přehřátím.
- Pro napájení nabíječe nepoužívejte nabíječe určené pro nabíjení autobaterií.
- Pokud nabíjíte akumulátor po předchozím použití (letu nebo jízdě), nechejte jej nejprve vychladnout na teplotu okolí.
- Vždy nejprve připojujte nabíječ k napájecímu zdroji a teprve potom nabíjený akumulátor.
- Nabíječ nerozebírejte!
- Nenabíjejte v uzavřeném interiéru auta a už vůbec ne za jízdy.
- Nabíječ nesmí být provozován dětmi do 15 let nebo osobami nepoučenými o správné obsluze přístroje a zacházení s akumulátory, ledaže by byl po celou dobu provozu zaručen dohled dospělé osoby znalé funkce nabíječe a s praxí s nabíjením akumulátorů.

Confirming the charging current
Make sure to know the maximum charging current of the battery before charging, never use excessive current to charge to damage your battery, which will result in over heat even explosion during the charging process. The charging and discharging rate of battery is usually marked with C value. Multiplying the charging C value and battery capacity equals to the maximum charging current supported by the battery. For example, for a 5000 mAh battery with a charging rate of 1C, the maximum charging current would be 5000*1= 5000 mA; therefore, the maximum charging current is 5A.
For a lithium battery, if it is impossible to confirm the supported charging C value, please set the charging current below 1C, for the sake of its (lithium battery) safety (the same applies to NiMH/NiCd batteries; no more than 0.1C for Pb batteries).

Task settings
Power on the charger and connect a battery; the charger will enter into the standby page. Short press the roller wheel to activate the program setting menu Program setting menu. The items in this menu are as follows:
| Battery | Battery type selection |
| Cells | Select number of cells in the battery pack |
| Mode | Working Mode: Charge, Discharge, Storage (lithium batteries only) |
| Current | Select desired charge/discharge current: 0.1-10.0 A |
| TVC | Terminal voltage control setting |
| Charge channel | Allows simultaneous charging of identical pack in both two channels |
| Start | Start charging/discharging program |
| Back | Return to previous screen or function |
Charging channel
This setting is convenient for charging multiple identical batteries (same type and number of cells, same capacity). You can select the channel to be started. Red indicates selected, and gray indicates not selected.
For example: When identical batteries are connected to both two channels, you can set both 1 and 2 to red; the charger will charge both packs simultaneously with the same setting.
Connecting the battery
Connect the charging leads to the respective XT60 output socket (CH1 or CH2) observing the correct polarity: (+) red cable, (-) black cable. For lithium packs, it is highly recommended to ALWAYS connect the balance leads and utilize balanced charging to ensure that the charger can accurately monitor the voltage of each cell.
Storage
When selecting the Storage function, the charger will automatically begin charging if the battery pack voltage is below the ideal storage voltage. Likewise, the charger will automatically enter the discharge mode if the battery pack voltage is higher than the ideal storage voltage.
Restoring an excessively discharged lithium battery pack
Restoring an Excessively Discharged Lithium Battery pack If the charger detects individual cell voltages that are too low to safely begin the regular charging process, it will automatically default to 0.5 A charge rate until the voltage has risen to a level that allows it to accept a fast charge rate safely.
Measuring internal resistance
The charger features the ability to monitor the internal resistance (IR) of each cell in a lithium battery pack. This feature is only operational when in the balance charging mode. Internal resistance can be useful to determine the overall “health” and performance of a lithium battery; the closer the IR values are between the cells in the battery pack, the better the battery will deliver its energy.
Working parameteres display
Rotating the roller wheel up or down during charging will switch the information displayed on the lower half of the LCD screen between cell voltage, cell internal resistance (IR) and working parameters. Cell voltage and IR can only be displayed during the balance charging process.
Dual independent output channels, setting and work independently as follows: Channel 1 charging, Channel 2 stand-by.
The colour LCD display clearly shows the working status of both two channels in real time.
Long press the roller wheel to activate the System Setting menu.

Power distribution:
AC input: 2x 50 W
DC input: 2x 100 W each; each channel has a maximum of 100 W
DC power supply
The charger may also be used as 17.5 V/max. 100 W DC power supply. In the AC input mode, you can connect an appliance (a LED lamp etc.) to the XT60 DC input socket. Check the specification of your device - be sure the device may be operated at 17.5 V AND the required input power is lower than 100 W (5.5 A). Due to the limited output power of the internal AC power supply you should not use the charger for charging in the same time, especially if the appliance was an inductive load (like an electric motor; its starting current might be 5–12 times higher than the regular running current).
Warnings and errors messages
Error message for abnormal battery connection
