    Problem with ratcheting gear 20CS on gas turbine

    Hi BigTom209. I have a similar problem where the baring gear is not working correctly and apears to be rotating in the wrong direction. I suspect the cage or parts within it has collapsed or is worn or damaged. Before we open it up it would be good to have a look at the photos you posted...

    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...

    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...

    MARK I Control System Backsheets

    It is not cost effective in this instance (client specific dynamics) to replace the existing MKI equipment. Controller replacement has already been explored. A cost effective solution is to hook up a number of analogue signals from the panel into a purpose configured data collector. The signal...
