Re: Deep sea PLC Current Sensing Problem

Thanks alex644,
That engine is not with me now so I can not check.
And what if there is voltage between battery "-" and ground of engine?
What causes that voltage difference?

Re: Deep sea PLC Current Sensing Problem

Yes i mean ground it's engine body, but sometimes there are a potention between earth and engine body. 1) check potentional between eng body and ground. Must be 0 volts.
2) check configuration soft: 3phase 4 wire. according picture. or you have another AC system?

Re: Deep sea PLC Current Sensing Problem

What u mean by that Engine ground?
We normally connected battery "-" direct on the engine body, is that engine ground u mean to say?

Re: Deep sea PLC Current Sensing Problem

As i understand: you connected CT in star but disconnected 54-com from ground?
Num: 1, 15-19, 7 must have good ground. May be you have some voltage between "-" battery and engine ground?
I usually connect "-"bat and engine ground together - one point.

Which parameter we should check in configuration?

Re: Deep sea PLC Current Sensing Problem

Hi,
Thanks alex644 for your reply.

Problem solved when we removed CT star point grounding.
But why ? ..I didn't get...

Any possible root cause from your side???

Deep sea PLC Current Sensing Problem

Hi Team,

 

We have Volvo penta TAD1641 engine in which we are using DSE8610.

 

Problem Description :

  1. When we are increasing load its current (Amps) readings not showing in Deep Sea controller.
  • we have checked Deep sea CT cables connection and also replaced but same problem
  • We have checked CTs and also for better replaced all, but same problem,
  • we have changed deep sea but same problem.
  • We have checked CT star point also, but not solved,

 

Can anyone help me out what could be the cause?
