Hi all,
following the CI by almost month we started getting high spread alarm mainly on spread1. To fix the situation we replaced all suspected TC and at the same time we checked CPD transmitter calibration as shown below:<pre>
ISS data:
0 psi o VDC
200 psi 5 VDC
As found readings:
0 psi 1.23 VDC
200 psi 6.32 VDC
After calibration
0 psi 0.85 VDC
200 psi 5.64 VDC</pre>
do you agree with me that the as found readings was letting the combustion to consume more fuel in order to compensate the faulty CPD readings?
then the whole engine eff will go down
Note: our machine is GTG frame6b with Mark IV control
