Time [s]
The output relay of the pulse length controller is clock-timed. The switching period T remains
constant. Depending on the divergence from the limit value, the switch on time tON is
increased or decreased in accordance with the proportional range Xp.
The following applies:
tON + tOFF = T (Const.)
greater divergence Î greater tON
Xp exceeded Î tON = T (relay remains picked up)
