ONsite Relay A’s indicator light will show one of three colors – green, yellow or red. This is an indication of the charge in the ONsite Relay A. Green means it’s fully charged. Yellow means it’s 70-30% charged and red means it’s less than 30%. If ONsite Relay A is flashing, that means it’s not connected to a power source.
