self-detection. Note ③ : When the automatic debugging cannot meet the requirements of the valve (the valve resistance is too large or there is a slight bite bite phenomenon), the sensitivity range needs to be appropriately increased to overcome the fluctuation. Note ④ : When the full trip is set to 0. Note ⑤ : You cannot change it easily until the parameter meaning is determined, otherwise it will cause abnormal work.

HART communication software in Chinese version Through the

FSK-HART-MODEMM and connecting to the PC machine, you can consult and modify all the parameters, and execute the commands. First, select the correct communication interface (USB port), and then press the

"Instrument Communication Test" button, after successful communication, other buttons can be activated. To select HART communication compatible

upper instrument for communication, the system with security

communication must also consider HART protocol compatibility issues, can connect a 250 ohm resistance in the circuit to improve the quality of transmission signals. The software is available through the supplier.

4.5 Calibration of the input signals Each instrument has calibrated the

input signal before leaving the factory, and the current input mA value  can be read by pressing the UP key automatically. Different standard  sources and changes in ambient temperature can cause small errors and  do not affect the use. For more demanding occasions, the user can go  through  the  circuit Built-in  switch  or hand operator and HART  communication software on the board. Enter the 4 and 20mA standard current, respectively, and press the built-in switch or handler or HART  communication software calibration command. Note: First calibration is  4mA and then calibration is 20mA.

5、Fault and exclusion

5.1 General Provisions The ALP210 is a precision instrument, which can

be installed in different models of regulating valves, with accurate setting  and  correction  of  electronic  components  and  mechanical components, easy to adjust and set. When operating the ALP210, the light fault does not affect the normal operation, and only when a serious fault occurs, if you continue to use it, it will damage the intelligent locator, and it is generally not recommended to repair it by itself.

Instructions Version Number:：20/01-2.01-CN

5.2 Troubleshooting method The ALP210 has no output (no gas output) 1)

Check whether the input 4~20mA signal of ALP210 is normal, and whether the display window can display the characters normally. 2) Check whether the gas supply meets the requirements of 0.15~0.6MPa, and check whether the pressure indication on the pressure gauge module is normal. 3) Switch to the manual state, and use the "UP" or "DOWN" switch valve to check whether the output pressure gauge has changed, and whether the valve is stuck. 4) Whether the feedback connection parts are loose and fall off. Control valve operation is abnormal (gas source, but regulating valve action is not normal) 1) Check the air supply pipeline for air leakage. 2) Check whether the feedback rod is loose. 3) Check whether the valve has a bite point, and the resistance of the sealing packing is too high. Adjust the tuning sensitivity (dead zone) parameters appropriately if the control requirements are not reduced.

5.3 Determine the fault of the locator with the display Working in Auto:

Press the UP key —— to display themA value of the current input current. Determine whether the input signal is normal. Press the DOWN key ——  to display the percentage of drive values currently output to the I /  P converter. Used to determine whether the I / P converter and amplifier  work properly.

5.4 Maintenance and return to the factory

1) Maintenance of the throttle: remove the circuit board, see the throttle

screws on the pneumatic amplifier, remove the throttle hole dirt and reinstall the throttle.

2) Maintenance of the relay: the fault of the relay is mainly caused by

the aging of the diaphragm, so you only need to replace the new diaphragm.

Instructions Version Number:：20/01-2.01-CN

3) Circuit board maintenance: the circuit board has been treated against moisture, but the site must avoid direct water entry. In work with large dust, open the upper cover regularly and clean the dust from the locator and circuit board with instrument wind. In the long-term shutdown state, the power transmission should be sent for 30 minutes every 3 months to prevent the internal capacitor from aging.

4) Return to the factory regulations: if there is a non-gas road fault,

do not remove and repair without authorization, so as not to affect the explosion-proof performance and safety! Be sure to return to the

manufacturer for repair.
