Hi Te-Chuan,

 

I thought it was odd that the spare would be powered.

The device Tim mentioned is probably a Moxa N5100A or N5150; we used something similar for the STGC gas system not long ago.

The are available and not too expensive, so we should have an alternate soon.

Hi All,

 

I was wrong.

I found some documents for IST cooling system in the FST cabinet.

Indeed, It shows we have 2 converters but one is used for TC-48-20 and one for HX86PA.

They are both in use, so we can not just simply swap the cables.

We do need to find a replacement for it.

 

Cheers,

Te-Chuan

Hi Christian,

 

Thanks for the reply.

FST cooling is currently running fine. Just some temperature values are not monitored (alarms for shift crews may not work properly), so need extra eyes on it.

I’m thinking that there are 2 set of TC-48 modules, OMEGA units and so on in the rack.

But, we actually only need one set of them.

Is it possible that we swap the cables and make the current TC-48 module in use work?

I’m probably wrong, so please correct me.

PS. Please ignore my previous email if you received it. I was sending with a wrong email account.

 

Thanks,

Te-Chuan

Hi All,

 

It looks like the RS-232/485 to Ethernet converter is dead.

Additionally, the controller has been discontinued by the manufacturer (note: site may not work properly on BNL networks):

https://in.omega.com/pptst/EIT-W.html

 

Tim knows of a replacement part that should work as a replacement.

He will order it if we don't have one on hand.

I'm not sure of the configuration of the failed converter, or even if it needed to be configured, so there may be some software work needed to get the replacement running.

 

Will we be able to run the FST if the alternate unit needs to be ordered?

 

Thanks,

Christian
