p7 -45 Ram and Rigal 5

[d309]

Hi, can any one help.

I have a Rigel 5 control box with p7-45 Ram.

All was well, then the control box came up with a error of ER11.

I phoned BFT and they said bad connection or something going to ground.

If it is the Ram, does anybody know how to check this or get the Ram repaired.
