5. Safety Notes Read the operating instructions attentively and particularly observe the safety notes. If the safety notes and the information in these operating instructions regarding proper handling are not observed, we assume no liability for any resulting injury/property damage. In such cases, the warranty/guarantee will also lapse. a) General • The unauthorized conversion and/or modification of the product is inadmissible because of safety and approval reasons.
c) Location for Installation • The charger is intended for dry indoor use only. It must not become damp or wet. Never set it up near a bathtub, shower or similar! If the charger is operated via the mains cable, there is danger to life from electric shock in case of moisture/wetness on the charger/mains cable! • Avoid direct sun irradiation, strong heat or cold. Keep the charger away from dust and dirt. The same applies to any rechargeable battery that may be connected.
d) Operation • The charger may be operated either via the mains voltage (100 - 240 V/AC, 50/60 Hz) or via a stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable mains adapter). Use only one of the two connection types, but never both at once. This may damage the charger. • Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.) while you are working with the charger or batteries.
6. Rechargeable Battery Notes Although use of rechargeable batteries in everyday life is a matter of course today, there are many dangers and problems. In particular, with LiPo/LiIon/LiFe/LiHv rechargeable batteries with their high energy content (in comparison with conventional NiCd or NiMH rechargeable batteries), various regulations must be observed in order to avoid the danger of explosion and fire.
• Never charge more than one rechargeable battery/battery pack at the same time. Always connect one single rechargeable battery/battery pack to the charger. • If the product is not to be used for an extended period of time (e.g. storage), disconnect any connected rechargeable battery from the charger and disconnect the charger from the voltage/current supply. The charger has no mains switch.
• Ensure that the battery does not overheat during usage, recharging, discharging, transport or storage. Do not place the battery next to sources of heat (e.g. speed controller, motor), keep the battery away from direct sunlight. There is a risk of fire and explosion if the battery overheats! The battery must never heat up to more than +60 °C (observe any additional information from the manufacturer!). • If the battery is damaged (e.g.

9. Commissioning a) Connection to a Voltage/Current Supply Attention! Always connect the charger to the voltage/current supply first; only then must a rechargeable battery be connected to the charger. The charger offers two different options for operation: • Operation via the mains voltage (100 - 240 V/AC, 50/60 Hz) • Operation via stabilised direct voltage (11 - 18 V/DC, e.g. via an external vehicle lead battery or a mains adapter) Never use both operating modes at the same time.
b) Connection of a Rechargeable Battery to the Charger Please observe the following points before connecting or charging/recharging the battery: • If you have not done so already, please read chapters 5, 6 and 7 completely and ensure that you have understood the information there.
Procedure when connecting a battery pack to the charger: 1. Connect the charger to the voltage/current supply. 2. First connect the charging cable to the two 4 mm round sockets of the charging output. Ensure correct polarity (red cable = plus/+, black cable = minus/-). The charging cable must not be connected to the rechargeable battery yet! There may be a short-circuit of the charger plugs; there is a danger of fire and explosion! 3.
c) General Information on Operation of the Menus • Select the desired submenu from the main menu using the "STOP" or the "–" button as described and confirm your selection with the button "START". • In a submenu, you can call the different settings with the buttons "+" and "–". • To modify a value, push the "START" button - the display then flashes. Modify the value flashing in the display using the "+" and "–" buttons. For quick adjustment of a value (e.g.
10. Main Menu After connection to the voltage/power supply, the start message will appear briefly. Then the charger is in the main menu.
11. Lithium Batteries (LiPo, LiIon, LiFe, LiHv) a) General The rechargeable battery programmes for LiPo, LiIon, LiFe and LiHv rechargeable batteries generally differ only in the voltages and the permitted charging current, see table in chapter 7. When charging a lithium battery, there are two different phases. First, the rechargeable battery is charged with a consistent current. When the rechargeable battery reaches its maximum voltage (at a LiPo rechargeable battery, e.g., 4.
b) Charging Batteries without Balancer Connection ("CHARGE") Of course, you can also charge multiple-cell lithium rechargeable batteries with a balancer connection with the rechargeable battery programme "CHARGE". However, the individual cell voltages are not reconciled here, so that one or several cells may be overcharged.
• Charging begins. The display will show various information on the current charging progress. Example: Li3S 1.2A 12.3V CHG 022:43 00682 At the upper left, the rechargeable battery type and the cell number are displayed ("Li3S" = Lithium rechargeable battery with 3 cells); the charging current is shown in the upper middle and the current rechargeable battery voltage at the upper right.
Important! Only a battery pack with exactly the same voltage for each cell provides the maximum performance and service life for a model airplane/vehicle. Variations in the quality of the materials used and the internal structure of multiple-cell lithium battery packs mean that the cells may have different voltages once discharged. Charging such a rechargeable lithium battery without balancer will quickly cause large differences of cell voltage.
• If the values need to be changed, push the "START" button. The discharging end voltage per cell flashes. Set this voltage with the button "+" or "–". Keep the respective button pressed for quick adjustment. The discharge end voltage set here applies per cell. The total voltage of the connected rechargeable battery is automatically calculated after setting the cell number (see below) and displayed at the lower right of the display. Confirm the discharging end voltage by pressing the "START" button.
e) Storing Batteries ("STORAGE") This rechargeable battery programme can be used if you want to store the rechargeable battery for an extended period. Depending on the rechargeable battery type set, the rechargeable battery is charged or discharged to a specific voltage. LiPo STORAGE 3S C= 3200mAh 2.0A Depending on the cell voltage, the battery is either charged or discharged. Of course, with a multi-cell battery pack, this is only wise if a balancer connection is available and connected to the charger.
12. NiMH and NiCd Rechargeable Batteries a) General The rechargeable battery programmes for NiMH and NiCd rechargeable batteries generally differ only in the internally used charging procedures. The settings in the menus are the same. The charger must be in the main menu. Select the rechargeable battery type matching the rechargeable battery used here with the button "STOP" or "–" (NiMH or NiCd), see figures on the right. Confirm the selection by pressing the "START" button.
Charge a NiMH or NiCd battery as follows: • First, choose the rechargeable battery type with the button "STOP" or "–" as described in chapter 11. a) (NiMH or NiCd) and push the button "START". • Select the rechargeable battery programme "CHARGE Man" with the button "+" or "–". The value at the lower right represents the currently set charging current. NiMH CHARGE Man CURRENT 0.
c) Automatic Charge Mode ("CHARGE Aut") In automatic charge mode, the charger checks the condition of the connected rechargeable battery (e.g. the inner resistance) and calculates the charging current from this. You need to set an upper limit for the charging current so that the rechargeable battery is not damaged by a too-high charging current. NiMH CHARGE Aut CUR LIMIT 1.
• When no display is flashing anymore, keep the "START" button pushed (approx. 3 seconds), to start discharging. • The charger now examines the connected rechargeable battery. In case of an error, a warning signal is output and the corresponding information is displayed. You can stop the warning signal by pressing the "STOP" button. You then return to the previous configuration menu. If no error is found, e.g. the display shown on the right will appear.
• Set the cycle number with the buttons "+" and "–" (1 - 5 cycles are possible). Push the "START" button briefly then to confirm the setting. The display stops flashing. • To start cycle programme, keep the "START" button pressed for longer (approx. 3 seconds). • The charger now examines the connected rechargeable battery. In case of an error, a warning signal is output and the corresponding information is displayed. You can stop the warning signal by pressing the "STOP" button.
13. Lead Batteries (Pb) a) General Lead batteries are completely different from lithium, NiMH or NiCd batteries. Despite their high capacity they can only provide low currents. The charging process is also different. The charging current for modern lead batteries must not exceed 0.4C; 1/10C is perfect for lead batteries. A higher charging current is not permitted; it would overload the rechargeable battery! This not only causes danger of explosion and fire, but also danger of injury from the contained acid.
The maximum possible charging current depends on the battery type and number of cells. The maximum charging power is 80 W. Confirm the set charging current with the "START" button. • The number of the cells in the lower right of the display flashes. Set the number of the cells with the buttons "+" and "–". Keep the respective button pressed for quick adjustment. Confirm the number of the cells by pressing the "START" button.
c) Discharging Battery ("DISCHARGE") This rechargeable battery program can be used to put partially charged lead batteries into a defined starting condition or to perform a measurement of the rechargeable battery capacity. The maximum possible discharging current depends on the battery type, battery capacity and number of cells. The max. discharge output of the charger is 5 W. This limits the max. possible discharge current of rechargeable batteries with multiple cells.
14. Saving/Loading Rechargeable Battery Data The charger has 10 memory slots in which you can store often-used settings. For example, the data (cell number, charging procedures, charging current) for 3 different LiPo flight batteries can be saved there, so that you do not have to set them anew every time. a) Saving Battery Data • Select the function "Memory Save" in the main menu of the charger with the button "STOP" or "–". • Confirm the selection by pressing the "START" button. The memory number flashes.
b) Loading Battery Data • Select the function "Memory Load" in the main menu of the charger with the button "STOP" or "–". • Confirm the selection by pressing the "START" button. • Select one of the 10 memories (01....10) with the button "+" or "–". The data stored in the memory are displayed, e.g. rechargeable battery type, rechargeable battery programme, cell number, charging and discharging current. PROGRAM SELECT Memory Load MEMORY LiPo [01] BAL 3S 1.
15. System settings The system settings of the charger summarise various basic settings. They are pre-applied with the most common values in the delivery condition. Depending on the rechargeable batteries you want to charge or discharge, however, certain changes to the values are sensible. Proceed as follows: • Select the function "User Set" in the main menu of the charger with the button "STOP" or "–". • Confirm the selection by pressing the "START" button.
Set the voltage for Delta-U-recognition (for NiMH or NiCd only) The charger uses the delta-U charging procedure for NiMH and NiCd rechargeable batteries to see if the rechargeable battery is fully charged. Instead of the internal default settings, the voltage value can be specified manually (in mV per cell). NiMH Sensitivity D.Peak Default NiCd Sensitivity D.Peak Default If the value is set too high, the charger may not recognise that the rechargeable battery is fully charged.
Switch the safety timer on/off and set the duration If charging starts, the internal safety timer starts as well. If the charger cannot detect whether the battery is fully charged for whatever reason (e.g. with delta-U detection), the charge process is terminated automatically after a set time if the safety timer is on. This protects the battery from overloading. Safety timer ON 240min The safety timer can be switched on ("ON") or off ("OFF"); the time for the safety timer can also be changed.
Max. cell voltage when charging The maximum cell voltage can be set depending on the set rechargeable battery type (LiPo, LiIon, LiFe, LiHv and Pb). The charger ends charging when all cells have reached the set voltage. LiPo: 3.80 - 4.20 V/cell (basic setting 4.20 V) LiIon: 3.80 - 4.10 V/cell (basic setting 4.10 V) LiFe: 3.30 - 3.65 V/cell (basic setting 3.60 V) LiHv: 4.00 - 4.40 V/cell (basic setting 4.35 V) Pb: 2.10 - 2.50 V/cell (basic setting 2.40 V) Battery end volt LiPo 4.
16. Fixed Voltage Output The charger offers the option of using the charging output (the two 4 mm output sockets) like a conventional controllable mains unit. In this case, the charger supplies a direct voltage to the output sockets; setting of 5.0 V/DC to 24.0 V/DC is possible. The output current can be set to between 0.1 A and 10.0 A. Observe that the maximum output current is not possible for the maximum current; the charger can only supply 80 W at most.
The output current is now flashing in the display. Set it with the "+" or "–" button (keep the respective button pushed for quick adjustment). • Briefly push the "START" button; the output voltage flashes. Set it with the button "+" or "–" (for quick adjustment, keep the respective button pushed). • Briefly push the "START" button. The current power intake and the output voltage are displayed. Briefly push the "STOP" button to end this function. The output is deactivated again.
17. Voltage Display for Lithium Rechargeable Batteries The charger can also display the current voltages of the cells of a lithium rechargeable battery. For this, the rechargeable lithium battery must have a balancer connection that must be connected to the charger. Proceed as follows: • Select the function "Battery Meter" in the main menu of the charger with the buttons "STOP" or "–". • Confirm the selection by pressing the "START" button. • Then the voltage display appears.
18. Display of the internal resistance The charger can display the internal resistance of the connected rechargeable battery. For multiple-cell Lithium rechargeable batteries, this is even possible separately per cell, provided that the rechargeable battery has a balancer plug that is connected to the charger (via the balancer board). Proceed as follows: • Select the function "Battery IR" in the main menu of the charger with the buttons "STOP" or "–". • Confirm the selection by pressing the "START" button.
19. Warning Messages on the Display REVERSE POLARITY The polarity of the rechargeable battery connections has been switched. CONNECTION BREAK The connection to the rechargeable battery has been disrupted, e.g. if the battery has been disconnected during the charging process. SHORT ERROR There is a short circuit at the output of the charger. INPUT VOL ERR A problem has been identified at the direct voltage input of the charger. BATTERY CHECK LOW VOLTAGE The rechargeable battery voltage is too low.
20. Information on the Charger Various information is indicated on the display during a charge/discharge process by repeatedly pressing the button "–". If you do not push any button for a few seconds, the charger will return to the normal display. The information that can be displayed depends on the connected rechargeable battery type. Voltage of the battery at the end of charging/discharging End Voltage 12.
21. Maintenance and Cleaning The product does not require any maintenance. You should never take it apart. The product should only be maintenanced/repaired by a specialist or specialist workshop or it may be damaged. Any rechargeable battery connected must be disconnected from the charger before cleaning. If the fixed voltage output is activated, disconnect any connected consumer from the charger. Then disconnect the charger from the voltage/current supply.
