Signal length
The signal length is calculated compared to the adjusted period time. In the drawing below the
effect of the proportional regulator is indicated.

In this example we have a 2 percent regulation deviation and an adjusted value of the KP = 200.
The calculated regulator value of the unit is 40%. Now the pulse length can be calculated with a
period time = 2500 ms:
The length of the period time will never be shorter than the adjusted ON time. The P regulator
causes the relay output to activate. The I regulator has the same effect on the relay output as
described on page 126 concerning the reset time t
