Macro for energy ring

[wanahduu]

Hi, i'm playing inferna and i need macro to use energy ring when there is a player on screen, i made macro with Self.Equip.Ring(3051) and used together with protector alarm player on screen, but to make this work i had to disable macros or it will wear energy ring everytime, so what i need is macro that use energy ring with macros enabled and only when player on screen. sorry for my english.
