The Gain Factor effects: Stability, Response time
- Higher gain results in: faster response, higher over- undershoot of pressure
- Lower gain results in: slower response, lower over- undershoot of pressure
Adjustment procedure:
1.Start with Gain Factor 1.0
2.Open valve.
3.Control a typical pressure / flow situation.
4.Repeat from step 2 with lower (higher) Gain Factors until optimal pressure response is achieved and stability is ok.

Normally adjustments down to Gain Factors of 0.42 should lead to good results. Otherwise you may need to improve sensor connection. Refer to «Requirements to sensor connection». |
