7.4.4 Controller
The type of controller and the input variables are defined here. Settings are
also made for self-optimization on the unit.
Controller 1—4
1. factory setting for controllers 3 and 4
2. factory setting for controllers 1 and 2
Filter time constant 0.0 — 1.5 — 40.0sec For adjustment of the 2nd. order digital input filter.
0 sec = filter OFF
For a step change in the signal, the response is
63% of the change after 2x filter time constant.
If the filter time constant is long:
- high damping of interference signals
- slow response of the process value
display to changes in the process value
- low upper frequency limit
(2nd. order low-pass filter)
