The type of controller determines the display of parameters. For some parameters, the decimal places depend
upon the equipment of the device. Factory settings are shown in bold print.
WALTHER Temperature Controller Bundle WTRB-x-x
Value Description
0...9999 Size of the proportional range: The larger the P-range, the smaller
the gain of the controller. For Pb = 0, there is no efficient controller
structure (same behavior as for limit value monitoring). For a steady
controller, Pb > 0 is required.
0 ... Influences the differential portion of the controller output signal. The
80 ... influence of the D-portion increases with an increasing derivative
9999 [s] time.
0 = derivative time turned off (no D-portion)
0 ... Influences the integral portion of the controller output signal. The
350 influence of the I-portion becomes smaller with an increasing reset
... 9999 [s] time.
0 = reset time turned off (no I-portion)
0.0 ... For a switching outlet, select the cycle time as follows: the energy
20.0 ... supply for the process should be almost continuous, and at the same
999.9 [s] time, the switching elements should not be overstrained.
0.0 ... Distance between the two controlling contacts in a three-point con-
999.9 troller
0.0 ... Switching differential for a switching controller with proportional
1.0 ... range Pb = 0 (same behavior as for limit value monitoring)
999.9
-100 ... Output level for P- and PD-controller (for x = w, then y = y0)
