Product Features
1、Overview
The electric valve intelligent locator is an intelligent signal acquisition and control system based on industrial microcontrollers. It is compact in size and can be installed in the junction box of the electric actuator or fixed outside in a DIN rail manner. It can directly receive 4-20mA/DC signals output by industrial instruments or computers (other input signal types can be customized before leaving the factory), and is matched with the potentiometer feedback electric actuator to perform precise positioning operations on various valves or devices. It can freely calibrate the angle (or displacement) of the electric actuator, and output 4-20mA/DC actuator angle position (or displacement) feedback conversion signals. The lower and upper limit values of the actuator angle position can be accurately set by pressing three buttons. The locator uses three button operation and nine LEDs. The lamp can directly display the locator mode, The 4-digit digital LED displays the actual opening value of the valve position, the set opening value of the valve position, and the temperature inside the locator housing through button switching, making it easy to operate.
2、Main technical indicators
Control accuracy: 0.1%~3.0% (adjustable through U4 parameter)
Can receive feedback signals from electric actuators: potentiometer 500 Ω~10K Ω
Can receive external control signals (DC): 4-20mA (customized before leaving the factory for 1-5V, 0-10V, switch quantity, etc.)
By modifying the U1 parameter, the following can be set: ① DRTA/forward action, RVSA/reverse action mode ② "Interrupt" mode when input signal is interrupted - OPEN STOP (stop) SHUT (closed)
Optional:
① Controllable silicon output (AC, 600V, 25A)
② Relay output (AC, 250V, 10A) ◆ Please specify when ordering
Output actuator position signal: Low drift output 4-20mA DC corresponds to actuator fully closed to fully open, signal completely isolated from input (photoelectric isolation), output load ≤ 500 Ω
Environmental temperature: 0~70 ℃, humidity: 35~85%
Equipped with over temperature protection function: When the temperature inside the locator shell is ≥ 70 ℃, the locator stops controlling the opening and closing of the actuator
Dimensions: ZXQ2003 → 77mm (bottom length) x76mm (bottom width) x51mm (height));
ZXQ2004 → 74 mm (bottom length) x 57 mm (bottom width) x 45 mm (height) The action range of the actuator corresponding to the input signal can be freely calibrated by pressing the button (generally calibrated as the fully closed and fully open position of the electric actuator)
Can set upper and lower limit points
Control function for actuator stalling detection: If the control actuator experiences stalling for 3-4 seconds, the locator will disconnect the control output for 1 minute; Repeatedly check and control until the blockage is eliminated.
Self adjustable accuracy can be set: If the actuator fails to position during operation and vibrates back and forth three times, the locator will automatically reduce the positioning accuracy by 1/1000 (i.e. original accuracy+1/1000) and repeatedly adjust it to the appropriate control accuracy. Set the parameter to U0 (000. x)
Password lock: prevent accidental operation
Anti frequent startup function of the actuator ● with error code indicating the cause of the fault (E0X)
Intelligent step distance adjustment and precise positioning based on input signal and actuator angle position
