Appendix 3 - LED Indications
LED Display Explanation:
G = green LED is lit
Y = yellow LED is lit
R = 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 (faults) has the LED pattern repeating until the fault is cleared
1. General Transitions:
• Controller start-up G - Y - R (one cycle)
• Pushbutton equalize start G/Y/R - G/Y/R - G (one cycle)
• Pushbutton equalize stop G/Y/R - G/Y/R - R (one cycle)
• Battery service is required all 3 LEDs blinking until service is reset
2. Battery Status
• General state-of-charge see battery SOC indications below
• PWM absorption G blinking (1/2 second on / 1/2 second off)
• Equalization state G fast blink (2 to 3 times per second)
• Float state G slow blink (1 second on / 1 second off)
Battery State-of-Charge LED Indications (when battery is charging):
• G on 80% to 95% SOC
• G/Y on 60% to 80% SOC
• Y on 35% to 60% SOC
• Y/R on 0% to 35% SOC
• R on battery is discharging
LOAD & LIGHTING CONTROL

The load status LEDs are determined by the LVD voltage plus the specified
transition voltages. As the battery voltage rises or falls, each voltage transition
will cause a change in the LEDs.
3. Faults & Alarms
• Short circuit - solar/load R/G - Y sequencing
• Overload - solar/load R/Y - G sequencing
• Over-temperature R - Y sequencing
• High voltage disconnect R - G sequencing
• Reverse polarity - battery no LED’s are lighted
• Reverse polarity - solar No fault indication
• DIP switch fault R - Y - G sequencing
• Self-test faults R - Y - G sequencing
• Temperature probe (RTS) R/Y - G/Y sequencing
• Battery voltage sense R/Y - G/Y sequencing
