The entire range incorporates an algorithm known as SMART. This
algorithm calculates the PID control parameters automatically on star-
ting (auto-tune) and during the process if any changes occur (adaptive
tune) without any user intervention.
The SMART function triggers its auto-tune action to calculate the PID
parameters.
This enables an optimum approach to reaching the setpoint.
The SMART function triggers its adaptive tune action to recalculate the
PID parameters if there is a change in the setpoint or a modification to
the load.
This function provides gradual preheating of the process.
This makes it possible to prolong the lifetime of the heating element and
avoid any thermal shocks.
If you require this function, simply set the required output power (OLH)
for preheating as well as its action time (t OL).
On starting, the inhibition function for the temperature threshold alarm
ensures that no fault indication will be acknowledged during preheating.
In addition, these controllers also offer the possibility of programming a
ramp to gradually increase power to further limit the risk of thermal
shocks.
There are many applications where it is often difficult to install a
sensor in the most ideal location.
Indeed, in several cases, the sensor is installed quite far away from the
desired location.
Installing a sensor at such a distance can generate a measured value
which is not actually representative of the process value.
It is for this reason that our controllers offer the possibility of
programming a constant shift value known as an OFFSET. This
OFFSET is the difference between the actual temperature to be
measured and the temperature of the location where the sensor is
installed. Thus, the value read on the controller is that of the
temperature at the monitoring point and not the value at the sensor
installation point.
