How to reset position of the triad used for translate function

Hi Everyone,

Normally, during Transform > Translate operation, the 'triad' (the movement arrows in 3 planes) is aligned to the center of the assembly. However, I have made an erroneous input and now the triad is some distance away from the assembly. The triad still moves the part, however I have to zoom out the screen to be able to view the assembly as well as the arrows.

• How to reset the triad so that it aligns once again to the center of the assembly?
• And if you could also tell what mistake I made to move the triad away from the assembly? 

Thanks in advance for your help,

Regards
