I have two questions about these regulators:
1) While doing the calibration of these servo valves, what is the difference between the Manual Calibration & the Auto Calibration?
2) In the configuration of these regulators in the TCQA Card, for example the regulator 43, we need to enter the following parameters:
Current Bias: (0 to 100% rated [10,20,40])
Current Gain: (0 to 200% rated_cur./%pos.)
Zero Stroke (0 to 6.667 Vrms):- LVDT 1: LVDT 2:
100% Stroke (0 to 6.667 Vrms):- LVDT 1: LVDT 2:
Pos limits (-128% to 128%):- Low High:
Integrator convergence gain (0 to 16 psi/%):
Position reference Gain (0 to 2 %/psi):
The Current Bias, Zero Stroke and 100%Stroke parameters are well documented in GE Manual on how can be calculated. However other parameters, Current Gain, Pos. limits, Integrator convergence gain and Position reference Gain, I couldn’t find a procedure that calculates these parameters. Are these parameters are calculated and updated automatically during execution the AUTOCALIB or there is exists a procedure to calculate them?
