4. Which country code are you using?

Hyuncheol Kim Welcome to Control Automation The simple answer is NO! At least until you send a simple schematic or sketch of what is there. 1. How many of each device? 2. Parameter of each device system? 3. If not new, how long has the situation existed? Regards, Phil Corso

Zia.. Welcome to Control Automation. ControlsGuy25, has asked you to provide the following Parameters: Motor Name Plate Data, including Excitation, Volts & Amperes. Measured Voltage, Amperes, kW, PF, Rpm. Regards, Phil Corso

Serg.... Do you know the approximate hours "Between" failures of the 1st 10 events? Phil

Serg.... Based on your latest data, and lacking TCM ( in rack) ) temperature measurements, my opinion is you have an End-of-Life situation! What has Triconex concluded! Phil

Serge There is the question of Possibility vs Probability! That is... anything is possible, but simultaneous (all at same time) lifetime failure is improbable! Q3. How many other TCM4351B cards, having an F&G function, are installed? Phil Corso

Q2. Do you know the hours of operation?

Serge84... Welcome to Control Automation! Q1. Were the 3 units monitoring the same function. For example... Flow, Temp, Level? Regards, Phil Corso

Et Al... There are actually 2 Standards: JIC-EMP-1967, covering Electrical Standards for Mass Production Equipment. JIC-EGP -1967, Covering Electrical Standards for General Purpose Machine Tools. Regards, Phil Corso ([email protected])

Et al... In 1967 JIC Std was issued! Its a 64 page standard covering Electrical Circuit Design Details. I forwarded a copy to this Forum several years ago! Unfortunately I have had no luck trying to uncover it! And because of Copy-Right laws I hesitate attaching it to this forum now. If you want...

Stadimet For very large Bulk Cargo ships, the generators are driven by extremely large Diesel-Engines. They are much larger than any used on even the the largest Cruise Ship! Regards, Phil Corso

Selk... I suggest you obtain the Cummins "White Paper, AGN-087" ! It covers the "Why PF = 0.8" subject from a manufacture's point of view. Regards, Phil Corso

IKE. 1) Since the situation is an emergency... 2) It's location is permanent... 3) In a plant having knowledgeable personnel... 4) Already connected to the load it's servicing... 5) And (in my words) requires simple closure of a Breaker at each MCC involved, then, NFPA-70 (NEC) Articles 250, and...

IKE43 6. How is the emergency system's 480-V output transferred to the 480-V system requiring it: a) connecting jumper cables, or b) transfer switch?

IKE43 3. By "Standby" do you mean it is "Portable", i.e., carried from one place to another.? 4. Or do you mean "Mobile", i.e., moved on wheels from one location to another? 5. Are the three Transformer secondary's Delta or Wye Connected? Phil Corso

IKE43 1. What is Generator Capacity? 2. What is load? Regards, Phil Corso

@stadimet If the propeller-shafts are driven by diesel-engines, then it very unlikely that any other generator connected to those diesel-engines will ever operate at the 50/60-Hz that utility generators must operate at for normal electrical loads! I think you mean that the gearing is such that...

Stadimet Hopefully this isn't the same Cruise Ship we discussed in 2018? ;) Does the Cruise ship you are talking about now have very large, say greater than say 20-15 MW, 4.16 to 11kV, Diesel powered generators or is it Azipod powered? Regards, Phil Corso

Brent77 My interpretation of your schematic is that you may not have achieved NEC Code requirements, if you are under its jurisdiction! Furthermore, there are people who "squeal" on others for not complying with code-requirements on these publicly available forums! If you still want to continue...
