I. overview

YWK-CT temperature controller with intelligent PID control, when the thermocouple (thermal resistance) collects the measured temperature deviation from the desired value, the YWK-CT temperature controller for the proportion according to the deviation measurement signal with a given value (P), (I), integral differential (D) algorithm, thus control the relay on-off ratio. The measured value restored to the given value, to achieve the effect of automatic control; the controller also has upper and lower limits of temperature alarm and relay output function, high cost performance, can be widely used in electric power, chemical, plastic, packaging and food enterprises

Five, terminal arrangement and wiring diagram

Six, panel description

1 the temperature measurement display: (PV) in normal operation, display the measured temperature value; in the parameter settings, display prompt;

2, control (set) temperature display: (SV) in normal operation, display control (set) temperature value in the parameter settings, display the value of the parameters;

3, the main control output indicator: when the output of the main control relay action, the indicator light; when the output master relay reset, indicating the lights off;

4, self tuning indicator: when the auto tuning operation, the indicator light;

5, alarm indicator: when the measured temperature is lower than the set temperature limit, indicator lights, alarm relay output; when the measured temperature is higher than the set temperature limit when the light is off, the output alarm reset relay;

6, the upper limit alarm indicator: when the measured temperature is higher than the upper limit temperature setting, indicator lights, limit alarm relay output; when the measured temperature is lower than the maximum temperature setting, indication lamp, output limit alarm relay reset;

7, the function control key: press this key for 0.5 seconds, the main control temperature into the set state, the main control temperature after setting, and then press the key for 0.5 seconds to save the settings and exit temperature control temperature setting; hold the key for 5 seconds, in other parameter settings, parameter settings after press SET for more than 5 seconds after the system will save settings and exit, return to normal state;

8, set the location shift key: in the set state, hold down the key can choose to set the parameters of the digital (one, ten, 100, 1000);

9, set the numerical value of the key: in the set state, press the key to reduce the number of one, hold down the number of fast;

10, set the value increment key: in the set state, press the key number plus one, hold down do not put the digital fast.

Seven, thermostat settings and operation

The main control temperature settings: normal working condition at the thermostat is energized, hold down the SET button for 0.5 seconds, red display prompt “ SO", green display master set temperature, the thermostat temperature control into the main settings, press shift, increasing or decreasing button can be set or modify the master temperature. After the master temperature settings, then hold down the SET key for 0.5 seconds to save the set temperature and exit the main control temperature setting, return to normal state.

Thermostat in normal state, hold down the SET key for 5 seconds, the thermostat into the set of the second. Then, each time you press the SET key, the display will transform a prompt red, green numerical display to display the parameters, select the shift, increasing or decreasing button can be set or modify the parameters. The following are the parameters set:

1, the lower limit deviation alarm settings: press the SET key to display “ SLP" green display shows the value of the parameter, select shift, increment, decrement key set or modify the parameters. This parameter indicates that the alarm point is lower than the difference value of the main control set point.

2, the upper limit deviation alarm settings: press the SET key to display “ SHP" green display shows the value of the parameter, select shift, increment, decrement key set or modify the parameters. This parameter indicates that the alarm point is higher than the difference value of the main control set point.

3, the proportion of range settings: press the SET key to display the “ P" green display shows the value of the parameters, select shift, increment, decrement key to set or modify the parameters. “ P" the larger the value, the lower the sensitivity of the main control relay output of the temperature controller, “ P" the smaller the value, the higher the sensitivity of the main control relay output.

4, integral time settings: press the SET key to display “ I" green display shows the value of the parameters, select shift, increment, decrement key set or modify the parameters. The shorter the integral time is, the stronger the integral effect is.

5, differential time settings: press the SET key to display “ D
