1-We have frequent PAS01 failures which are installed in Bailey Infi 90 PCU. What could be the possible cause.

2- Failure of two DSI02 cards installed in Bailey Infi 90 PCU. What could be the possible cause.

3- Address / Bus error (error code 2, 5, 6)on Primary MFP whereas secondary MFP took over control. What could be the possible cause.

 

1. PAS01 power supply cards are now no longer supplied by ABB. They are the old style and probably should be replaced. Here in Australia we get ours repaired (ABB send them to a 3rd party), usually its a capacitor failure.

2. DSI02 cards are quite old the replacement cards are the DSI22. You should look at replacing them.

3. If the MFP's are old and perhaps in a corrosive environment the address switch may be damaged and causing the address to change on the run. We had that problem, now we have air scubbers.

There are a number of other reasons that could have caused the card failures but usually if the card is over 10 years old replace it.

dear mr. tahir,

on top of what mr. jennings said, u may want to check the address setting of your MFPs, as you may know, the address of that particular MFP is set in dipswitch SW3.. the address
of this MFP and its redundant should not be a 1 or a 0, and obviously, it should not be the same as any other address on the controlway..

 

Dear Tahir,
1) We faced the same problem with Bailey power supply modules (PAS02). THe problem got solved after replacing all Bad batch PAS02 modules.
The cause was due to the capacitor used in that module.

2) Regarding 2,5&6 error, we are also facing the same problem. What is your firmware revision of your MFP02 modules?. Are you using GPI in the same module?. We were told that the Adderss 0r bus error could be due to program corruption, due to noise from the power supply.
