5.1The order of calling out each function

hController power on operation:

After the controller is powered on, the upper row displaysSYThe lower row displays the division mark, indicating the input type. after passing through2After seconds, the upper row displays the upper range limit and the lower row displays the lower range limit, indicating the measurement range. after passing through2After seconds, the upper row displays the measured value and the lower row displays the set value, entering the standard display mode.

hTemperature setting:

pressSETKey, upper displaySP, press5or6Press the key to display the desired value in the lower row. Press the function key, the upper row will displayST(in minutes), press5or6Press the key to display the desired value in the lower row, then click the function key to return the controller to standard mode.

5.2Detailed description of each function

hPVZone display:

If displayed“ ”It indicates that the sensor is open or the input signal exceeds the measurement limit; If displayed“ ”If the sensor is short circuited or the input signal is below the lower limit of the range, it means that when the input signal of the controller is not within the range, the buzzer will sound and press any key to silence it.

hTime inquiry:

When the controller is working in standard mode, simply press the shift button, the upper row will display the timer time, the lower row will display the controller set time, and then press5Key, the controller returns to standard mode.

hTimer function:

WhenSTset to0When the timing function is cancelled, the controller runs continuously; WhenSTSet not to0Only when the controller has a timing function, will the lower row display when the controller's running time is upENDThe buzzer beeps, the controller stops working, press any key to silence, and at the same timepress5Keys and6key4secondCan be restarted. When the timer function is activatedRUNIf the indicator light is flashing and there is no timer or if the timer has not been activated yetRUNThe indicator light stays on for a long time,ALMThe constant of the lamp indicates a fault alarm.

hWater level indication and replenishment function:

When the water level is low, display“0000”And it will sound an alarm, the buzzer will beep, the heating output will be automatically turned off, and any key can be pressed to silence the sound

5.3The self-tuning function of the controller (setting the set time to0Cancel the timer and set the timer time after the self-tuning is completed

If the temperature control effect is not ideal, please activate the self-tuning function and press6key4seconds laterATThe indicator light flashes, and the controller starts self-tuning. After self-tuning automatically endsRUNThe indicator light stays on for a long time; At this point, the control effect will be greatly improved.

hDuring the self-tuning process, press6key4The running indicator light will stay on for a long time after seconds, and the self-tuning will stop. The controller will operate as beforePIDControl the parameters.

The functional parameters are shown in the table below

three Precautions

1When an alarm is detected after turning on the machine, please check if the water is in place

2If leakage is found after prolonged use, please check if the heating tube is damaged, as the heating wire is220VConnect the AC voltage directly or check if there is any collision causing the circuit and insulation tube to fall off. If you do not understand electrical principles, please absolutely prohibit disassembly and repair. Notify our factory for repair.

Heating temperature is high, resulting in water evaporation. During use, a dedicated person should be present to supervise and prevent direct contact with the instrument casing to avoid burns.
