Sensor Delay adjustment effects: Stability
Adjustment range is from 0.0 to 1.0sec
Pipes and orifices for sensor attachment delay response time and so badly impact pressure control stability.
By adapting this parameter to the approximate delay time stability problems can be reduced. But control response time will be slowed down by this measure.
Whenever possible sensors should be attached to the chamber according to «Requirements to sensor connection». This is the most effective measure against stability issues. If your gauge attachment fulfills these criteria do not use this parameter. |
Adjustment procedure:
1.Start with Gain Factor 1.0 and sensor delay 0s.
2.Open valve.
3.Control a typical pressure / flow situation.
4.Repeat from step 2 with higher sensor delays until best possible stability is achieved.
5.Adjustment Gain Factor again. Refer to «Gain factor adjustment».
