Maybe I am just an old fasshioned PLC person, but Delta V is so not "user friendly" for trobleshooting, like the situation when you cannot measure 24DC voltage in the loop for dry contact when contact is close, and you just have a LED ON on the card that indicates that that this contact is...

Tnanks guys for your ideas, we tried capacitor, did not work. Finally made some changes to avvoid using 120VAC in this paricular starter for control and do not have anymore this issue. Now just curious, Is it common in the US do not have a separate ground structure for power and...

We are in the process of replacing Bailey DCS to Deltav. everything was working on Bailey same VFD same cable just different input card for dry contact 24VDC instead of 48VDC. Stadus LED on the Deltav Input card. No fault on VFD. I guess this AC "background" was OK for 48VDC on Bailey but...

Control loop for motor with VFD . One cable Start, running indication, + another for 4-20MA speed control. Running indication is Dry contact (Delta V 24VDC input card) taken out of VFD (Toshiba). When everything ready to go ,channel status LED on the input card is blinking. Checked voltages...

Thanks, That what I was thinking. To send all the data to historian, build some displays.I do not need online analysis. In case of trip I can pull the data and investigate.Now I have to check what resolution I can get on DeltaV historian, and how critical it is for turbine monitoring 1 sec, 125...

Thanks ScottyUK, And sorry my bad it is 13MW. You are right this equipment is relatively rear. But in some cases people buy systems with a lot of features and never use them. That what I am trying to figure out, what is the must and what is a nice to have. I mean if we need all Emerson's...

Thanks, You are right it is mostly for preventing something very bad. So we probably do not need all this complicated stuff like analyzing software. And this is how Emerson makes money. License for everything, and renewal every year. 100k USD (by the way) where about 25k for software. I do not...

Hi all, need your advices.Small power plant , 3 steam turbines (13KW each) Have to find solution for vibration protection and prediction monitoring. Plant is switching over to DeltaV. Emerson has a solution for everything, but it is very very expensive (more then 300k just for vibrations for 3...

Thanks a lot! That's what I was looking for. Hope I will be able to deal with these microscopic terminals and power termination of the carreer. Regards BB

Need your help folks. I need to bring 4-20 signal from 4 wire current transmitter to 2 wire input card (Delta V). It was surprise for me that in Delta V i have to use a pair of cards for the same field signals. What are the options? Thanks BB

Hi all, need your advice. I am dealing now with upgrading of Bailey Infi to Deltav, (small heating/power plant). All field instruments should be disconnected from the Bailey cabinets, moved to the auxiliary JBoxes and using multipair cable connected to DeltaV cabinet. Somehow happened that this...

Thanks a lot, just kinda unusial to see 3 phase 480v 200HP motor power cable in the same tray with 4-20ma control cables, hope it will work.

Hi all, I am new in US so it was suprise for me to see control signal cables pulled together (Analog, digital) in the same trays, and also see the multiconuctor cable with different voltages iside (48VDC, 120VAC)Personally I don not like it. Question is if there are codes and standarts for...
