[King_Kingston]

Error code 39427, Rectifier communication missing

Description
The communication with the rectifier on drive comm link arg, drive
module arg has been lost.

Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
This may be caused by a faulty or lacking signal connection between
the rectifier and drive units.

Recommended actions
1) Make sure the signal cable is correctly connected between the
rectifier and drive unit.
2) Perform a shutdown and then restart the system.
3) If the problem persists, isolate the faulty unit and replace it.

Hope this helps!!!
