Alarm function

KR1 has the capability to generate various types of alarms based on the process requirements.

- Absolute low alarm (LoAb)
- Absolute high alarm (HiAb)

Absolute band alarm with alarm indication out of the band
Absolute band alarm with alarm indication inside the band
Sensor break
Deviation low alarm (relative)
Deviation high alarm (relative)
Relative band alarm with alarm indication out of the band
Relative band alarm with alarm indication inside the band

Control function

The device can be programmed for 2 control types:

- Two control actions (heat & cool) with 2 methods:
- PID (heat and cool);
- Heat/Cool ON/OFF control with neutral zone;

and

- One control action (heat or cool) with 4 methods:
- PID (heat or cool);
- ON/OFF asymmetric hysteresis;
- ON/OFF symmetric hysteresis;
- Servomotor control (available when Output 2 and Output 3 have been ordered as “M”)

KR1 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.

Timer function

Five timer types are available:

Delayed start with a delay time and a “end of cycle” time.
Delayed start at power up with a delay time and a “end of cycle” time.
Feed-through.
Asymmetrical oscillator with start in OFF.
Asymmetrical oscillator with start in ON.

Programmer function

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.
