Atlas-Copco Memory Chip Loses Data -Display blank

by Tony Sylvain
(Springfield, VA)

I have 5 Atlas-Copco screw compressors, GA110Ws, GA160Ws, and a GA160VSD with Mark III controllers. I've had at least a half dozen controller failures over the last three years usually after power outages--the controller fails to come back online after the outage except for a series of 16 numbers on the controller display. Each time I have to send the controller to MEIInternational to have a new memory chip installed and the controller reprogrammed at a cost of $1200 each time. I want to get rid of the Mark III controller and replace with a third party controller. Do you think this is a viable solution and if so, do you know the names of companies that provide such products?
