I ran into an old Teletrol 186 Integrator today that is has the "error light" on solid. They lost their building's transformer and now the system will not run. There is no information on site about this system. Does anyone have any info or manuals for this system?

Recently their old GE/Fuji freq drive blew its top so we put in a Johnson Control freq to get them back up. This is an old Marlo hot deck/cold deck system but these people do not have a lot of money as they are a low profit organization that helps people.
Thanks,
John
