Servomotor control (available when Output 2 and Output 3 have been ordered as “M”)
KM1 also has the Fuzzy overshoot control feature that reduces the overshoot usually present at instrument start-up or after a set point change, and by setting a value between 0.00 and 1.00, it is possible to slow down the instrument action during the set point approach.
These instruments are able to perform a set point profile compounded of 4 groups of 2 steps (8 step total).
The first step is a ramp (used to reach the desired set point), the second is a soak (on the desired set point). When a RUN command is detected, the instrument aligns the operative set point to the measured value and starts to execute the first ramp.
In addition, each soak is equipped with a waiting band which suspends the time count when the measured value goes out of the defined band (guaranteed soak).
Moreover, for each segment, it is possible to define the status of two events. An event can drive an output and make an action during one or more specific program steps.
Some additional parameters allow defining the time scale, the automatic RUN conditions, and the instrument behavior at the end of the program.
All steps can be modified during program execution. During program execution, the instrument stores the segment currently in use and, at a 30 minutes interval, stores also the elapsed time of the soaks. If a power down occurs during program execution, at the next power up, the instrument is able to continue the program execution starting from the segment in progress at power down, and if the segment was a soak, it is also capable of restarting from the soak time minus the stored elapsed time.
The first step is a ramp (used to reach the desired set point), and the second is a soak (on the desired set point). When a RUN command is detected, the instrument aligns the operative set point to the measured value and starts to execute the first ramp.
