Description
Self-optimization (autotuning)
Standard features include the tried and tested
self-optimization (oscillation method), which
makes it possible for the controller to be
matched to the control loop by a user who is
not a control technology expert. Here, the re-
action of the control path to the specific vari-
able changes is evaluated and the controller
parameters proportional band, reset time, de-
rivative time, cycle time, and filter time con-
stant are calculated.
Ramp function
The ramp function is used for a constant
change of setpoint value w up to the ramp limit
value SP (entered setpoint value). A rising or
a falling edge arises depending on the actual
value at the time of ramp start t0. The slope is
defined by a gradient which is entered during
the controller configuration.
Firing curve
The firing curve is used for controlled starting
and time-dependent firing of small pottery
kilns. The user can enter setpoint values, gra-
dient, and firing time directly at the device.
Limit value monitoring
The controller is equipped with two limit value
monitoring functions, each with eight configu-
rable alarm functions. Any analog signals can
be selected as actual and setpoint value from
a selector. When a limit value is exceeded, a
signal can be displayed or an internal control-
ler function initiated. With the limit value mon-
itoring, extensive alarm and limit value
functions can be implemented.

Timer
The timer is started manually or automatically
(after power on, for example). When the timer
expires, the timer output signal changes its
state (configurable). The timer can be used to
implement functions like time-limited control or
setpoint changeover.
Setup program
The setup program provides the user with an
easy and comfortable way to configure the
controller using a PC.
The PC has to be connected to the controllers
USB interface (Mini-B type) with a USB cable.
Thereby the controller is powered over the
USB interface. As a result, no mains supply is
required during the configuration.
