LED Indications

The Tandem has three LEDs one red (charger), two green (ready and status). The status green LED indicates three states; 1) solid green LED indicates Tandem is operating as a charger. 2) Flashing status green LED indicates Tandem is operating as a power supply. 3) No green LED indicates power has been removed from Tandem.

The red and green LED’s will indicate the charging status of the battery. The following table identifies all of the LED indications and their meaning:

LED INDICATION

MEANING

 

 

Alternating

Indicates that the Tandem is evaluating the battery and/or

Red & Green

communicating with a DIGITAL battery, loading battery

 

parameters and determining the appropriate charge routine. A

 

low voltage (<11V) battery will cause this indication to continue

 

until the battery is “rejuvenated” to a safe charging voltage.

 

NOTE: This indication will continue if a non-Anton/Bauer Logic

 

Series battery is mounted on the charger. These batteries cannot

 

identify themselves to the Tandem and will not be charged.

Steady Red

Indicates that the battery is being held by the Tandem to stabilize

 

an out-of-range temperature condition.

Flashing Red

Indicates that the battery is currently under Stage One charge.

 

 

Flashing Green

Indicates that the battery is currently under Stage Two charge.

(slow rate)

 

Flashing Green

Indicates a fully charged DIGITAL battery is placed on the

(fast rate)

charger and a FUL cutoff condition cannot be met. The charger

 

is VERIFYING that the battery is in a full charge condition.

Steady Green

Indicates that the battery is READY and in Stage Three Lifesaver

 

mode.
