Product Features

1.3" OLED screen,it features no view restriction, high brightness,energy saving and environment protection,in real time to

show valve opening angle and external control command.Enter sleeping state automatically after about 5 minutes,it could

display location state and its control command during sleeping time.

△ Original valve adjustment mode:cover-opening free and interactive

step1:Press the button to control valve to the position of "counterclockwise full open", then save it .

step2:Press the button to control valve to the position of "clockwise full close" ,then save it to finish the valve adjustment.

Thoroughly eliminate the complex and inconvenient factors caused by mechanical positioning.

△ 16 bit high performance MCU,12 bit high precision AD conversion chip are applied,built-in unique algorithm,thoroughly

eliminate valve on/off inaccuracy caused by mechanical hysteresis,espacially suitable for 3-way valve adjustment.

TCN 02EX total series and other DC24V series:built-in motor control module,variable frequency speed control of

motor can realize accurate positioning.

△ Non-contact positioning,control unit modular design and potting processing are applied to guarentee components work reliable

and greatly improve product service life;Interface uses standard connectors,convenient for installment,adjustment and

replacement.

△ Menu can report failure in real time(including stuck situation or other fails caused by actuator does not put valve on/off

position in place)and output failure warning signal.

△ Menu operation can realize exchange of valve control command.

△ Menu operation can switch freely between remote control and local setting,press the button to realize opening/closing .

△ Menu operation can set valve off position deviate to "On" or "Off" direction,to bring convenience to local valve adjustment

compared with "Simple On/Off mechanical positioning".

△ Menu operation can adjust valve running speed of the actuator in real time.

△ Menu operation can restore factory default setting.

Notice

1.Test condition:Test under rated load, 25ºC working temperature and 50% humidity,one test circle(twice the time of running cycle),which will be influenced by different load

and working environment.

*2.Fault signals are selectable function,output by relay,factory defaults settings do not take this function.

*3.F type is suitable for the ambient of high humidity(≥90%) but without long time rain.

*4.Use hexagon spanner when power off,or use button when power on.
