4.
Loop rise time too high (Display: "Ts = > 8h")
The time is determined by a measurement, which the control loop
requires at a 100 % dosing rate of the dosing system or the dosing
pump, to increase the actual value to 50 % of the measuring range.
This measurement is indicated by the message "9: Ts!" and may
take up to 4 hours.
If any of the error conditions described above occur, adaption is
interrupted. The measuring amplifier indicates an error message.
The "old" parameters Xp and Tn are not changed.
Determination of the control
parameters with known Tu and
Ts times
If the loop times Tu and Ts are already known or if these cannot
be determined automatically due to specific system conditions, the
loop times can be entered into the "Tu" and "Ts" menus. When Tu
or Ts are saved, the control parameters Xp and Tn are also
calculated and entered into the menus.
