Dbnd - Insensitivity Range (Dead Band); Kp - Amplification Factor Of The Process Controller - Burkert 8792 Operating Instructions Manual

24.3.2 DBND – Insensitivity range (dead band)
This function causes the process controller to respond from a specific control difference only. This protects
both the solenoid valves in Type 8792/8793 and the pneumatic actuator.
Factory setting: 1.0 %

24.3.3 KP – Amplification factor of the process controller
The amplification factor specifies the P-contribution of the PID controller
(can be set with the aid of the P.TUNE function).
Factory setting: 1.00
