configuration levels, internal adjustments).
Safety devices independent of the controller, such as overpressure valves or temperature
limiters/monitors, should always be provided and should be capable of adjustment only by
specialist personnel.
Please refer to the appropriate safety regulations in this connection. Since auto-tuning (self-
optimization) cannot be expected to handle all possible control loops, there is a theoretical
possibility of unstable parameter settings. The resulting process value should therefore be
monitored for its stability.
- All input and output lines that are not connected to the supply network must be laid out as
shielded and twisted cables (do not run them in the vicinity of power cables or components).
The shielding must be grounded to the earth potential on the instrument side.
