Faulty/broken MD4

L.P.C 2 months ago in Master modules / MD4 • updated by Cole Koster 2 weeks ago 4

We have had multiple MD4 units (7 and 10 inches) no longer powering up.

Do you have any idea what could cause that?  We're using fuses to protect the units, but sometimes they still seem to fail on normal operation.

If you suspect the modules have been damaged, sending them for repair might reveal clues to what has happened. 

For this type of question, you need to get in touch with your Parker sales rep or local distributor. 

I have a similar issue with a customer. Relatively brand new machine (<1 year old) and they are reporting the MD4-7 no longer powers on. It is fuse protected, and the display is located inside an enclosed cab so I believe it is an internal issue.

Can you confirm that the display brightness was not inadvertently turned down to 0%, making it appear to not function?

I'm not near the machine but I can confirm that. When attempting to do a remote login and pull the program I got an error stating IQAN could not detect the MD4-7 [1] and that the operation failed. There is also an MC43 on the machine but it would not pull without seeing both masters.
