Deckel Dialog 11 FP50 Error 1016

I am reaching out for help with error 1016 on the self test screen of my Deckel Dialog 11. Does anybody have information on this error, or explanation of error codes? When this happened, I checked the computer rack and saw an error light at slot7 NPP location. I cycled the power to machine and on boot up the error 1016 halts the machine at self test for too many errors. Am attaching picture of self test screen. Appreciate any information on this.
