ABB PM634 Issue (AC110)

Hello everyone,


I am currently facing an issue with two spare units (the last two we have available). As soon as the processor starts to boot, it immediately reboots and continues in a loop.

When attempting to start in DIAG mode, the unit shows a D0 error. According to the manual, this indicates that the module should be replaced.

Has anyone experienced a similar issue before?

Also, this may be a long shot, but does anyone happen to have a spare PM634 available for sale?

Kind regards,
