The E-Port control is the cornerstone to this Rechargeable Drive System and the information below is an aid to diagnosing the various signals that the two LEDs on the 18650 E-Port can display. If the up or down button is pressed with the controller in a wallplate connected to a motor the TOP LED should light up for a few seconds to indicate that motor drive is occurring. If the up or down button is pressed with the controller out of a wallplate the TOP LED should flash to indicate the controller is trying to drive but there is no load.
When a charger is plugged directly into the bottom of the controller the CHARGE LED will always illuminate (even if for a few seconds) to show that power is available to the controller when required. The charging condition can be tested using the information detailed at point below.
