9 Parameterization
Switching peri-
od 1
(C
y1
)
0 to 9999 s
factory setting:
20.0 s
If an output of a controller channel is con-
figured as a Pulse length output, the period
between the switching pulses is fixed.
The length of the switching period should
be selected such that, on the one hand, the
cyclic controller output signal (e.g. for heat-
ing, cooling, feeding etc.) does not cause
any disturbing fluctuations of the actual val-
ue, while, at the same time, the switching
outputs and the equipment being con-
trolled are not stressed unduly.
Switching peri-
od 2
(C
y2
)
Contact spacing
(X
sh
)
-0 to 999.9
(Unit
dependent on
the actual value
input variable)
factory setting:
0.0
Minimum control deviation at which switch-
ing controller outputs become active
Used to protect switching outputs and the
connected equipment when controlled by
modulating and continuous controllers with
pulse outputs. With very small control devi-
ations, switching of the controller output is
suppressed.
Switching hys-
teresis 1
(X
d1
)
0 to 999.9
(Unit
dependent on
the actual value
input variable)
factory setting:
1.0
Switching distance between the output
states (on/off) In switching controllers (pro-
portional band = 0)
The Switch hyst. (switching hysteresis)
should be selected such that the actual val-
ue resulting from the switching controller
output signal does not vary too much,
while, on the other hand, the switching out-
puts and the equipment being controlled
are not stressed unduly.
Switching hys-
teresis 2
(X
d2
)
Actuator time
(TT)
5 to 3000 s
factory setting:
60 s
Time required by an actuator to cover the
entire output level range.
Working point
(Y0)
-100 to 100 %
factory setting:
0 %
Constant value used to correct the control-
ler working point
The set value corresponds to the output
when the actual value and the setpoint val-
ue are identical (control deviation = 0).
Used in controller structures without an I-
term as a manual output level offset to
eliminate persistent control deviations.
max. output
(Y1)
0 to 100 %
factory setting:
100 %
maximum output
not active, limit monitor response (propor-
tional band = 0)
Min. output level
(Y2)
-100 to 100 %
factory setting:
-100 %
minimum output level
not active, limit monitor response (propor-
tional band = 0)
