What to do if BIAS value exceeds limit on tissin TS900 Valve Positioners?
If the BIAS value exceeds the limit, run Auto-Calibration again. Accuracy is significantly reduced when used without auto-calibration.
Why is the valve end point set too high on my tissin TS900?
A valve end point might be set too high on your Tissin Valve Positioners due to strong vibration or external shock. To resolve this: ? Check if the positioner is installed too high or low. ? Check if the positioner is installed too far from the actuator (check the angle of use). ? Check if the potentiometer gear and main gear are out of position.
Why is the valve zero point set too low on my Tissin Valve Positioners?
A valve zero point might be set too low on your Tissin Valve Positioners due to strong vibration or external shock. To resolve this: ? Check if the positioner is installed too high or low. ? Check if the positioner is installed too far from the actuator (check the angle of use). ? Check if the potentiometer gear and main gear are out of position.
