Recently purchased a late 90's model Mitsubishi Milling center with the Meldas 520MT.
At power up, drives come on and some relays light up as well as some of the pmc push buttons (coolant on/off, etc.).
However, there is no display on monitor and no led's on QX521 card.
No machine ready light or responce?
QX084 card has green led's lit.
QX141-1 card has green led's lit and one red led blinking.
Seems to have power going to display but no data so to speak.
Back lamp to monitor is lit.
All cables seem to be connected properly.
Backup battery checks ok. (not sure how long machine sat)
Anyone have these symtems before?
Thanks for your help!
