Selection /
setting
possibility Explanation
Range of the control error (actual - set point),
0 to 9999.9 ( 1 )
in which the output level is proportional to the
control deviation. The smaller the proportional
range is selected, the greater the output ratio
change per deviation. If the proportional band
is set to a value of 0, the controller will
automatically function as a limit switch without
PID controller structure.
0 to 9999 s Influences the differential component (D
component) of the controller output signal.
The purpose of the D component is to
dampen the temporal actual value gradient,
and thus to suppress the tendency to vibrate.
The effect of the D component is stronger
with larger derivative time.
0 to 9999 s Influences the integral component (I
component) of the controller channel. The
purpose of the I component is to minimize
steady-state error. The effect of the I
component becomes weaker with greater
reset time.
When an output of a controller channel is
configured as a pulse width output, the period
of the switching pulses is fixed here. The
cycle time should be chosen so that, on the
one hand by the clocked controller output
signal (i.e. heating, cooling, metering, etc.) no
interfering actual value fluctuations arise on
the other hand, the switching outputs thereof
and driven resources are conserved as
possible.
Minimum of deviation from which switching
-0 to 999.9 ( 1 )
regulator outputs are active. It is used for the
protection of switching outputs or connected
equipment when driving continuous
controllers with pulse outputs. For very small
deviations, the switching operations of the
controller output are suppressed.
The operating distance between the output

0 to 999.9 ( )
states (on / off) for switching controllers
(Proportional range = 0) The switching should
be selected so that the actual value will not
vary greatly from the output of the switching
regulator; on the other hand, the switching
outputs and which controlled resources are
conserved as possible.
- 100 to + 100% Constant value for correcting the operating
point regulator
The set value corresponding to the output
level when the actual and setpoint values are
equal (Deviation = 0). Is used when the
controller structures without an I component
as a manual output level offset for the
elimination of steady-state deviations.
0 to 100 % maximum degree of operation is not effective
at limit of switch behaviour
(Proportional band = 0)
-100 to +100 % Minimum output not effective in limit switch
behaviour (Proportional range = 0)
0 to 60 s Based on the min. Relay switch-on time of the
pulse length is to the bottom, and the pulse
frequency is limited to the top. The switching
frequency for switching relay outputs is
limited thereby.

output
0 to 999.9 s Delay the switch-on edge at limit switch
