I have read through all I can find and have reviewed the CSP generated by the MKV (TTXMV4 and TTXSPV4). Checked all the control constants associated with the generation of the exhaust thermocouple arrays, average calculations, spread calculations and spread limit calculations. A frame 6 unit...

I am on a site where all MkV SDCC JP23 jumpers are set to 1/2. The MkV manual advises that these jumpers should be set to 2/3. The panel appears to behave correctly. Should these all be changed to 1/2 and if so what difference should I expect? On checking the spare cards in storage I fnd...

I am trying to understand if there are/were any Frame 9E units fitted with Lean Head End Liners. Please let me know if anyone has and knowledge of this option. The OEM literature is vague in this respect. It appears the Frame 9B units had this as an option.

The MKV TMR panel in question has a full compliment of SDCCG4AHD cards. One has developed a problem and we would like to change it out for a replacement, however the only replacement we can find is an SDCCG4AGD, which is an earlier revision. In the past I have changed out cards with newer...

Please advise if you have had any experience operating conventional combustion frame 5 units with low sulfur diesel. Units are equipped with standard universal fuel pump/bypass valve/flow divider with speed pickups no starting motor. I am interested in any changes that may be required to the...

A number of years ago I helped solve an issue where Frame 9B units with LHE liners were not lighting off well and did not achieve full speed without flaming out one or two cans. The station had a number of liner sets, but the liners had not been kept in sets. This allowed the sets to get mixed...

I've four .rsp files to open. I believe they came from PLC5, but I only have access to RSLogix5000. Could someone open them as pdf? I can be contacted at [email protected] if anyone can help.

On the MKV simplex a logic point which is also a <C> contact output is written to by a normally closed bigblock output. The bigblock is also in <C>. Modbus reports this contact output point changing state fleetingly, however the contact output does not physically change state. The logic can...

This frame 5 unit is 40 years old or so. During attempted starts the unit lights off ok, but fails to get to 60% to break away. Fuel rate increases and exhaust temperature rises towards isothermal. We suspect the torque converter or diesel. We are checking diesel engine speed. for the...

On a few occasions now, when the <C> processor is rebooted while <R> <S> and <T> are in normal operation and the unit is stopped, sometimes a unit START signal is received in <RST> sequencing. Sometimes a Diesel start is sequenced. Could this be because the processor I/O is not establishing...

I am trying to collect diagnostic data from Mark I system. Do you know of anywhere I can obtain MKI backsheets?
