Take a look at the LED indicators and let us know what they say. Here's a guide:

LED Indications

Valuable information can be provided by the three LED’s visible through the front cover. Although

there are many different LED indications, they have similar patterns to make it easier to interpret

each LED display. Consider as three groups of indications: General Transitions // Battery Status

// Faults & Alarms.

LED Display Explanation

G = green LED is lit

Y / R = yellow LED is lit, then red LED is lit

G+Y = Green and Yellow are both lit at the same time

G+Y / R = Green & Yellow both lit, then Red is lit alone

Sequencing LED patterns (faults) repeat until the fault is cleared

General Transitions

• Controller start-up G / Y / R (one cycle)

• Equalize request start G+Y+R / G+Y+R / G / G

• Equalize cancelled G+Y+R / G+Y+R / R / R

• Battery service is required* all 3 LED’s blinking until service is reset

*battery service notiﬁ cation is only enabled in custom settings

Battery Status

• General state-of-charge see battery SOC indications below

• Absorption state G blinking (½ second on / ½ second off)

• Equalization state G fast blink (2 to 3 times per second)

• Float state G slow blink (1 second on / 1 second off)

Faults & Alarms

• Over-temperature Y / R sequencing

• High voltage disconnect G / R sequencing

• DIP switch fault R / Y / G sequencing

• Self-test faults R / Y / G sequencing

• Remote Temperature Sensor (RTS) G+Y / Y+R sequencing

• Battery voltage sense G+Y / Y+R sequencing
