The following table describes the indicators on the energy storage module (ESM) as shown in ESM Indicators. Note that each of the four ESMs have these LEDs.

Table 5 ESM Controls and Indicators

Ready to Remove LED (blue)
On – The ESM can be safely serviced.

Off – The ESM cannot be serviced, a charge is present.


Caution - If the amber LED is on while the blue LED is on, the ESM is faulty and is ready to remove.

Fault LED (amber)
On – An ESM fault has occurred.

Off – No ESM fault is present.

OK LED (green)
On – The ESM is charged and operational.

Slow blink – The ESM is in the process of charging. This process can take up to 10 minutes.

Fast blink – The ESM is in the process of discharging. The discharge process might take up to 5 minutes to complete.
