We have two mark vie controllers for Gas turbines. One of the PDIO module failed while GT online and alarmed, Control system fault inhibit. PDIO was showing without any indications. We removed the load on the machine and while at FSNL, replaced the PDIO with a spare one. The module didn't...

MarkVie is switched off core by core for Gas turbine maintenance. When we switch on power after the maintenance, always one or two core doesn't boot. It flashes 7 times indicating ROM failure. We had to remove the flash card and reflash it. Most times it works. Sometimes even after flashing...

I am using Allied Transys AT8624T/2M switch in Markvie UDH/PDH network. One of the switches failed. We have a spare switch. I would like to know how to configure this switch. I connected this switch to a PC and using PUTTY software logged in. But further, I couldn't proceed. The commands gave in...

In our plant, we have two frame 5GT's (12 MW each) and one H25 (25 MW) Hitachi Gas turbines. The Hitachi Gas turbine has FSRLLBIAS factor kept as 3% to restrict the GT to take sudden load. It is limited to take 4.2 MW maximum only. Why is this factor necessary? According to them it is kept to...

We are replacing Generator breakers (6.9 KV) VCB with New ones which are designed to close much faster than the existing ones. Does this need any setting change in ToolBox in Mark Vie? What is the effect on the Gas turbine? We have two Frame 5 GT's with Mark Vie. Circuit breaker supplier...

We found that the new moog valve installed in Frame5 GT with MarkVie control was showing more than 5% difference in feed back and command in the lower side. Tried to adjust null bias current. but it has to be increased to 5.5 % to get the feed back and command nearly equal. So we tried to...

We have two Markvie retrofit (TMR). one of the unit, we changed out gcv, srv and lfb servo valves during maintenance and carried out lift calibration. after this we started getting, L3GRVFLT Gas ratio valve position servo trouble and L3GRVSC_ALM Stop Ratio Valve servo current fault alarms...

We have two Frame5 LA machines with MarkVie control. recently commissioned. we are using honeywell flame scanners. The #2 and #3 flame indication in HMI is different (#3 shows half of #2 in one unit and vice versa in other unit) 340 Hz and 180 Hz. Also the indication keeps moving and causes...

Hi Everybody, I would like to make temporary changes in MarkVie when I receive alarms. I do not want to build and download every time. For eg. GCV/SRV valve position margin change. You can change it. But unless you build and download, the changes will not take place. Is there a way to make...

SRV position at valve full close position was found negative 4.2% and LVDT voltage was 0.625V. we did calibration after adjusting LVDT to 0.7 v and auto calibration showed 0.2 %. After one day operation, when the unit was stopped the valve position again shows negative 4.2%. Actual valve...

We have installed MarkVie control system recently. We have printing problem now. Printer stops printing very often. We have to stop and start the project / HMI to resume printing. do anybody face this problem?

Hello, We have MarkVie system. I have few issues with alarm display and printing. 1- Alarm display is not fully seen in display page. It goes beyond the page and no scrolling facility. 2-Alarms and messages gets truncated in printer. Only partially prints 3- Alarm lock facility not...

Can anybody explain how to change cimplicty trend lines color and width properties permanently in cimedit?

we are using honey well flame scanner P/N261A812P012 for MarkVIE. But this scanner is not good for diesel fuel operation. I believe GE recommends to use Geiger-Mueller scanner. Has anybody knows the Geiger-Mueller Part number for MarkVie flame scanner.

Is anybody know where can I get the analog input scale values in MarkV other than Io.asg.list. Also How can I force analog value in MarkV? Please advice.

I would like to edit a ladder logic. the procedure I follow is like this. Make necessary editing and save the sequence edit file. then table_compile followed by eeprom. Is this correct. Can anyone assist?

We are looking for Gt performance software with MarkV control. Is any software in the market which runs with MarkV? Can anyone help?

After replacing the srv servo valve, we checked the LVDT voltages and found as 0.74 V at 0%. Actual valve position is also -0.1 % in HMI. In machine operation, srv passes even when it is in negative position (-2.1%) shown by the HMI value. I tried to put -10% value and got LVDT voltage as...

Where can I get the GE part numbers for the MarkVIe control system spares.

I would like to change the pen width in cimplicity trend to make it prominent while printing. Default setting is zero. Does anyone know this?
