Changing a User Preset’s charge rate
You can change the charge rate for any User Preset. The new rate is retained (even after power is
cycled) until you change it again (this behavior can be changed via Charge Control Software).
1. Navigate to the Preset Menu.
2. If the User Preset you want to change is displayed, go to step 3.
otherwise
Press the Mode button until the preset you want is displayed.
3. Press and hold the Mode button. This displays the Operations Menu, which cycles through
several screens. When you see CHOOSE CHG. RATE, release the Mode button.
4. The display now shows the preset’s charge rate (on the bottom line).
5. Press the Mode button to cycle through available charge rates (some rates are currents [A or
mA], others are multiples of pack capacity [C]; the list wraps around).
Tip: Quickly press and release, press and hold, then release the Mode button to re-
verse the sequence of charge rates. This enables you to go back to a rate, rather than
running through the entire list. The tone you hear when you press the Mode button indi-
cates which direction you are going: high tone for forward, low tone for reverse.
Tip: Currents change in 5mA increments for small packs, and in 0.250A increments for
large packs (depending on how presets are confi gured).
6. When the charge rate you want is displayed, press and hold the Mode button. This applies
the charge rate to the preset and returns you to the Operations Menu.
7. In the Operations Menu, release the Mode button when you see the operation you want.
Clearing a User Preset
You can remove User Presets you don’t need. For example, if you don’t regularly charge A123
and Lead Acid batteries, you can remove those to limit the Preset Menu to the presets you do use.
The fi rst 20 presets in the Preset Library are the same as the 20 factory-installed User Presets (see
list and descriptions later in this manual), so you can easily restore any presets you remove.
1. Navigate to the Preset Menu.
2. If the User Preset you want to remove is displayed, go to step 3.
otherwise
Press the Mode button until the preset you want is displayed.
3. Press and hold the Mode button. This displays the Operations Menu, which cycles through
several screens. When you see CLEAR PRESET, release the Mode button.
4. You are prompted to confi rm your action with the message CLEAR PRESET?. Press the
Mode button to switch between confi rming the removal (>Yes) or denying the removal
(>No).
5. When you have selected the desired response to the prompt, press and hold the Mode button.
If you selected Yes in step 4, the preset is deleted.
6. You are returned to the Operations Menu. Release the Mode button when you see the opera-
tion you want.
Tip: If you are using the Charge Control Software, you can shorten the Preset Menu by
hiding User Presets you don’t use, as well as hiding Empty Presets. See “Confi guring
User Presets,” later in this manual.

Monitoring charging operations
When you start a charge at the charger, the CCS opens a dialog that enables you to save the
charge graph.
To save the graph: Enter a name for the graph, navigate to the directory where you want
to save it, then click Save. (If you keep the default name and location, the graph previ-
ously saved there will be overwritten.)
To prevent saving of the graph: Click Cancel.
To monitor cell voltages, total pack voltage and related charging parameters during charg-
ing: Click the Cells tab.
To view charge parameter graphs: View > Graphs. In the Graph window:
To view volts for individual cells: View > Cell Volts.
To view total pack voltage: View > Pack Volts.
To view current: View > Amps.
To view fuel level: View > Fuel.
To print a graph: File > Print.
Limiting charger input current
The charger will draw up to 5A to deliver its 4A maximum output current. The high input cur-
rent is required when the input voltage must be boosted to drive packs having larger numbers
of cells in series. The charger monitors input current from the power supply, and automatically
reduces pack charge current if it determines that the power supply can’t keep up.
You can also manually limit the charger’s input current so the charger will not draw more power
than the supply can provide. If you know your power supply is rated for 3A output, for example,
you can limit the charger’s input current to 3A. This feature prevents damage to power supplies,
such as bench supplies, having low to moderate output currents. (Be aware that limiting charger
input current may increase pack charge times.) When the charger is powered from a high current
source (such as a car battery), you can override manual current limiting to provide maximum
pack charging current.
To monitor supply voltage: Click the Supply tab.
To manually set input current limiting:
1. In the Supply tab, select the desired maximum current in the Current Limit dropdown list.
2. Click the Update Charger button.
To override manual input current limiting at the fi eld without using the Charge Control Soft-
ware:
1. Press and hold the charger’s Mode button.
2. Connect the charger’s input cables to the power source.
3. When you see characters in the charger’s LCD display, release the Mode button.
Note: If manual input current limiting is in effect, you must repeat this procedure each
time you apply power to the charger if you want the charger to operate at full input cur-
rent.
Setting charger options
1. Click the Options tab.
2. Set options as desired.
3. Click Update Charger.
Graphs available depend on
the selected User Preset.
