Start of autotuning after power-on and during the approach phase
H
With output type “solid-state”, the cycle time during autotuning is
reduced to 8 x the sampling cycle time.
With the “relay” output type, care has to be taken that the process value
is not influenced by the cycle time, since otherwise autotuning can not be
completed successfully.
Solution: Reduce the cycle time Cy, until the process value is no longer
influenced. (Manual mode can be used for the adjustment!)
