Item Description
1 Charging Output (%) LEDs
• The LEDs illuminate like a bar graph displaying the present total
output charge current as a percentage of the maximum rated
charge current. For example, unit model TC4012 has a maximum
rated charge current of 40 A so at 60% the charger’s current output
is 24 A. The numbers below the LEDs represent the percentage
values. See Figure 1-4 on page 1–10.
NOTE: When the maximum Charge Output current is limited via
the optional Remote panel, the LEDs will still display the total
charge output current as a percentage of the maximum rated
charge current and NOT as a percentage of the limited charge
current.
• One or two LEDs may flash intermittently in combination with a
solid Fault LED (indicating a fault) or with a flashing Fault LED
(indicating a warning). The icons above the LEDs represent the
various types of fault and warning conditions. See Figure 1-4 on
page 1–10.
2 Fault LED
The LED may illuminate a solid light (indicating a fault) or flash
intermittently (indicating a warning) in combination with flashing
Charging Output (%) LEDs. See Table 1-1, “Fault and Warning
Indicators” on page 1–11 for details.
3 Charger Status LEDs
Displays the current status of the charger.
• Ready - a solid light indicates batteries are fully charged and the
charger is not in float stage.
• Ready and Charging - solid lights indicate batteries are fully
charged and the charger is in float stage.
• Charging - a solid light indicates charger is performing a normal
charge cycle.
• Equalize - a solid light indicates that the charger is performing an
equalization cycle.
- a flashing light indicates that the equalization cycle
will begin after the absorption stage is done.
