isl 6, the charger/discharger.
easy to handle that it is possible to use without any instructions after a short time.

News 2001: isl 6-330d, the new 'low end' charger of our isl 6 series.
Its features are similar to the well known isl 6 series, but it contains a single row display.

News 2001: Softwareupgrade for isl 6 series:

a) upward revaluation of the battery 2 charging output:

1-6 cells Nickel-Cadmium = 1.2 ... 7.2 V,
1-6 cells Nickel-Metallhydrid = 1.2 ... 7.2 V,
1-4 cells Lead acid = 2...8 V,
1-3 cells Lithium-Ionen = 3.6 ... 10.8 V,
1-3 cells Lithium-Mangan-Oxid (Tadiran) = 3.0 ... 9.0 V.

To charge the maximum rated cell count a 13.8 V supply voltage is necessary!
From softwareversion 7.03 (or higher) isl 5 and isl 6 charger hardware is modified to make it possible to charge the above listed cell counts.
If you want to upgrade your elder isl 5 or isl 6, you have to ship the charger to Weiterstadt (Germany) to modify the hardware and software!

b) The new software remembers the charging and discharging capacity of the combination programs.
You can recall to display.

c) The new software supports the serial RS 232 port.
To read battery data on you personal computer, you need following parts:
i6-RS-schn: interface to install in isl 6 series charger
i6-RS-kab: connecting cable from Laptop/PC to charger
winsoft: pc-programm to receive, show and evaluate the battery data
i6-RS-einb: price to mount the interface in the charger
i6-RS-upgrade: package price of software, interface, cable, winsoft and mounting of the interface into the charger.

If you want to upgrade your elder isl 5 or isl 6, you have to ship the charger to Weiterstadt (Germany) to modify the hardware and software!

Isl 6 means: intelligentes schnell ladegerät (intelligent quick charging device) of the sixth generation.

By his functionality, the isl 6 is a pure chameleon: In one box, you get a unique, fully automatic charging and discharging device, whereby belonging to the microprocessor, accumulator maintainance - and capacity measuring programs could be integrated with a relatively high precision.
Despite his universality the use is as easy as ABC. The use is logically, and with only two (folios-) pushbuttons you have all options under control.
This is only possible with a MICROPROCESSOR inside.

Extract of our german instructions for use:

The isl 6 has and can:
Pb - accumulator (lead-acid and lead-gel batteries) charge- and discharging programs.
Ni-Cd / Ni-MH accumulator charge- and discharging programs.
Fully automatic Ni-Cd cell charging adjustment through the microprocessor (patent pending)
This means: Fully automatic adjustment of all charging parameters of your accumulator over the entire charging cycle!
The isl 6 charging devices operate on 11 to 15 VDC, but may only be connected directly to a 12 V car battery!
Even regulated power supplies as a rule do not meet the stringent DC requirements of the device!
When isl 6 is connected to the car battery, car must stand still and motor must be switched off.

1) automatic mode (outputs akku1 and akku2)
The charger does not require any adjustments! It adapts itself automatically to any flightpack (Accu 1).
a) To use the charger, connect it to your 12 V car battery. The display shows
- p1, ready to charge in Automatic Mode (p1 = flight pack)
- p2, ready to charge 4 cells, 500 mA (p2 = Rx pack) [*]
[*] For 5-cell receiver batteries and / or 330 mA charge current please see below.
b) Plug the battery pack(s) to be charged to their appropriate sockets on the front panel.
In automatic mode isl 6 now starts to charge with 300 mA, the current afterwards rising successively to the optimal value for the connected pack(s), to descend again at the end of the fast charge cycle, which the buzzer announces by a 30 sec (appr.) beep. After automatic cut-off the equipment starts to trickle charge the packs in order to conserve the stored capacity.

2) manual modes output 1 (flight pack, pack 1)
In case you do not want to use the equipment in automatic mode, select first whether the pack is to be charged ("+") or discharged ("-"), by pushing the corresponding button several times before plugging in the battery pack.
Afterwards, again with the buttons, a desired discharge current (extending from 25 mA to 2 A and shown one by one on the liquid crystal panel - but discharge is not available at isl6- 636e) can be selected, respectively a charge current between 100 mA and the maximum current appropriate to the connected pack.
Please note, that for safety reasons the value of 8 A (isl6-636+) is only accessible in automatic mode.

3) automatic mode combination programs (output akku 1)
Between the charge and discharge "table" on the menu several additional automatic programs are installed, which allow a choice of discharge/charge cycles for formatting ("breaking-in" by three times discharge/charge) of new batteries and for reconditioning packs which have not been used for some time. These programs too can be stepped to by the "+" or "-" buttons.
Note: when discharging a receiver pack at Accu 1 output (which is normally charged at Accu 2 output) the discharge current of the automatic discharge program has the same value as the charge current used at Accu 2 output (up to the number of cells which are used at Accu 2 output)!

4) lead accu charge and discharge (output akku 1)
When accu1 output is disconnected, you reach the lead accu discharge and charge programs by pressing the "-" button continuously. You must connect PB (plumbum) accus with a nominal voltage of 2, 6, 12 and 24V only!
PB-c: charges with low currents. For instance to be used with packs of low capacity (less then 3Ah).
PB-C: charges with higher currents for "quick charging".
PB-d: discharges with a maximum current of 200mA. Qualified for measuring capacities.
PB-D: discharge programm starts with the highest current the device is able to give without damage.
Both programs discharge down to 1.75V per cell.

5) configuring power on reset and/or cutoff automatc mode (output akku 1)
Subsequent to keeping both buttons depressed WHILE HOOKING UP isl 6 to the car battery, the buttons allow (re)configuring of the device to henceforth always start with either
- the fully automatic charging program, or
- with whichever program run last,
depending on whether you select "FAUTO" or "LAST".
5.1: select one of the two modes fauto or last.
After having chosen the startup-program-mode, you have to chose the sensitivity of cutoff feature.
The "normal" sensitivity will give mostly best results with sealed Ni-Cd cells (xxxxSCRC, xxxAR ...)
The "sensitive" or "sensitive+delay" mode will cut off current when detecting a flat charge voltage curve.
This mode will give best results when charging mixed cells (1700 SCE, RED AMP, most transmitter batteries ...)
Note:
In sensitive modes, it is possible, that automatic will cut off at the beginning of the charge process, when charging deep discharged cells. To avoid this, it is possible to start a delay timer, which activates cut off automatic after the delay of 8 minutes. This means, that your packs will be charged for a minimum of 10 minutes! Do not charge full packs in mode "sensitive+delay", they will become too hot!
Ni-MH packs:
Charge tests gave best results when cut off mode is set to one of the sensitive modes. It is necessary to use the manual modes of current setting. Do not chose charge rates of more than 1C. e.g.: 1100mAh packs must be charged with 1A.
5.2: select one of the three sensitivity modes; + button shows you "more" possibilities, - button select the displayed mode.
5.3: select switch mode for external 25 W indicator lamp (this menu appears even when no lamp connector is installed).
5.4: The following item displayed on the menu applies only, if the optional features "melody module" have been procured.
It is possible to chose one of 12 melodies. (Please note, that melody module is not available this time)

6) settings for output akku 2 (rx pack, pack 2)
Pushing "+" button only WHILE HOOKING UP isl 6 to the car battery produces the menu for selecting the number of cells (4 or 5) in the receiver pack.
Reply with the appropriate button, also for the charging current (+=more means: show more possible values, - = your choice). The current-settings beyond 500mA are shown in (parenthesis). These current values are not available for Accu 2 output but for Accu 1 output (see below). The charger will charge with its maximum current of 500mA.
If you are using an automatic or automatic combination program with your receiver pack at Accu 1 output, the current setting of the Accu 2 pack is used as the discharge current setting (up to the number of cells) of Accu 2!
The settings of 4) and 5) are automatically saved and kept in nonvolatile memory.

7) Verification of actual mode and of applied charge
Symbols used:
"*" indicates, that the device is at its power limits and has reduced the charging current accordingly, whereas the pack would
be capable of absorbing more current than isl 6 can furnish.
"!" signals, that at this moment the microprocessor is monitoring the pack to determine and possibly adjust the charging current
to a new optimum value.
"a", "b", ... appear in this sequence after a voltage peak has been detected and indicate in ascending probability, that the battery
is full.
"f", "e", ... appear as an inverse letter to show, that the battery is full or empty.
"t" indicates that the rapid charge cycle is terminated (full) and trickle charging has begun.
a) Actual charge/discharge mode:
Pushing ONE button ONCE displays the actual mode of operation. The indicated values may differ from the original setting as a result of the automatic adaptation of the device to the condition of the pack being treated.
b) Capacity state:
Simultaneously pushing and HOLDING BOTH buttons displays the charge applied to the pack(s) up to that moment. This verification remains possible even after the pack(s) has/have been disconneced.

8) error mode
Besides an automatic reset provoked by a condition unknown to the software and produced by unforeseen outside interventions or errors and warnings, the charger can be reset on purpose by removing one of the charging cable’s clamps at the car battery.

9) technical data:

All Data given is based on a 12.5V car battery voltage.
Recommended battery size for isl 6 chargers: 12V / greater 63Ah, min. 12V/42Ah.
Tolerances at Pack 1 currents (isl 6): typ. 5%; max. ca. 15% or 250mA (larger value counts)
Tolerances at Pack 2 currents (isl 6, receiver): typ. 5%; max. ca. 10% or 100mA (larger value counts)
