GX.

THE ERROR LED IS ILLUMINATED OR FLASHING.

The flashing LEDs on your charger indicate an Error Condition. Read below for a quick guide on the Error Conditions on the GX Series Industrial Chargers.

Understanding Advanced Diagnostics

Advanced Diagnostics is used when displaying Error Conditions. It will display a series of blink sequences that help you identify the cause of the error and potential solutions. All Error Conditions are displayed with the Error LED and Standby LED flashing back and forth. The number of flashes between each pulse denotes a potential Error Condition (except reverse polarity and low-voltage battery).

1. Error LED

All Error Conditions are displayed with the Error LED and Standby LED flashing back and forth. The number of flashes between each pulse denotes a potential Error Condition (except reverse polarity and low-voltage battery).

2. Standby

In Standby mode, the charger is not charging or providing any power to the industrial battery. Energy Save is activated during this mode, drawing microscopic power from the electrical outlet. When selected, an orange LED light will illuminate.

3. Charge LEDs

The charger has four (4) Charge LEDs per bank - 25%, 50%, 75% and 100%. These Charge LEDs indicate the connected battery(s) state-of-charge (SOC).

4. 24v normal

For smart charging Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries. When selected, a white LED will illuminate.

5. 24v cold/agm

For charging industrial batteries in cold temperatures below 50ºF (10ºC) or AGM batteries. When selected, a blue LED will illuminate.

6. agm

For charging industrial batteries in cold temperatures below 50ºF (10ºC) or AGM batteries. When selected, a blue LED will illuminate.

7. 24v lithium ion

For charging lithium-ion batteries, including lithium iron phosphate. When selected, a blue LED will illuminate.

8. 24v repair mode

An advanced industrial battery recovery mode for repairing and storing, old, idle, damaged, stratified or sulfated batteries. When selected, a red LED will illuminate and flash.

9. 24V Supply Mode

Converts to a DC power supply. When selected, a red LED will illuminate.

Error

Reason/Solution

Single Flash

Single Flash

Battery will not hold a charge. Have battery checked by a professional.

Double Flash

Possible battery short. Have battery checked by a professional.

Triple Flash

Battery voltage is too high for selected charge mode. Check battery and charge mode.

Quadruple Flash

Abnormal AC grid power: VAC <85V or >250V, or Frequency <45Hz or >65Hz.

Error LED Solid Red

Reverse polarity. Reverse the battery connections.

Standby Solid Orange

Battery voltage is too low for charger to detect. Verify connection and mode selection, if still not working use Supply Mode to raise battery voltage.
