Debugging Steps for ABB TZIDC Intelligent Electric Valve Positioner

The ABB TZIDC intelligent electric valve positioner is currently the most commonly used intelligent electric valve positioner. It is a digital intelligent electric valve positioner under ABB, mainly suitable for single-acting, double-acting, linear stroke, and angular stroke actuators. It supports Hart communication. The ABB TZIDC intelligent electric positioner, due to its vibration resistance, can still provide reliable operation in a vibration environment of 10G at 80HZ, making its application very widespread. When we purchase a new ABB TZIDC intelligent electric valve positioner, it is crucial to perform initial debugging. Today, the technical editor from Shaanxi Huibo Electromechanical will introduce the debugging steps for the ABB TZIDC intelligent electric valve positioner, hoping to assist users.
　　Debugging steps for the ABB TZIDC intelligent electric valve positioner:
1. Before connecting the gas source, first empty the gas source pipe for a period to eliminate possible dust, impurities, water, oil, etc. in the pipeline. It is recommended to empty for 30 minutes, and you can use your hand or white paper, white cloth to check the quality of the gas source. Note: If damage to the positioner is caused by dust, impurities, water, oil, etc., ABB will not provide a warranty. Check whether the pressure after the pressure reducing valve meets the nameplate parameter requirements of the actuator (the maximum supply pressure for the positioner is 6 BAR, but the actual supply pressure must refer to the maximum gas source pressure allowed by the actuator).
2. Connect the 4---20mA input signal. (The working power supply of the positioner is derived from the input signal, powered by a DCS two-wire system, and the voltage directly applied to the positioner must not exceed 30V/50mA, otherwise it may damage the positioner circuit).
3. Check the installation angle of the position feedback rod (if the positioner and actuator are supplied as a whole, it has already been installed and debugged by the actuator supplier, and only needs to be checked and confirmed; this step is not mandatory):
• Press and hold the MODE key.
• At the same time, click the ⇧ or ⇩ key until the operation mode code 1.3 is displayed.
• Release the MODE key.
• Use the ⇧ or ⇩ key to operate, making the actuator run to the two terminal positions, and record the angles of the two terminals.
• The two angles should meet the following recommended angle range (minimum angular displacement of 20 degrees, no strict symmetry required).
The linear stroke application range is within -28º---+28º.
The angular stroke application range is within -57º---+57º.
The full stroke angle should not be less than 25º.
If the angles do not meet the above requirements, adjustments must be made to the feedback rod, coupling, or the installation position of the positioner to ensure that the angle values meet the above requirements.
4. Start the automatic adjustment program (it is best to recalibrate through this program after the actuator or valve is installed in the system):
Method 1: For linear stroke valves.
• Press and hold the MODE key for 5 seconds until 'ADJ_LIN' appears.
• Release the MODE key.
• Press and hold the MODE key again until the counter on the display counts down to 0.
• Release the MODE key, and the automatic adjustment program begins to run (the display shows the program statement number in progress).
• The automatic adjustment program takes about 5 minutes. After successful completion, the positioner will automatically store the parameters obtained from the automatic adjustment and switch the control mode to 1.1 CTRL_FIX.
Method 2: For angular stroke valves.
• Press and hold the ENTER key for 5 seconds until 'ADJ_ROT' appears.
• Release the ENTER key.
• Press and hold the ENTER key again until the counter on the display counts down to 0.
• Release the ENTER key, and the automatic adjustment program begins to run (the display shows the program statement number in progress).
• The automatic adjustment program takes about 5 minutes. After successful completion, the positioner will automatically store the parameters obtained from the automatic adjustment and switch the control mode to 1.1 CTRL_FIX. If a fault occurs during the automatic adjustment process, the program will be forced to terminate and display a fault code. Based on the fault code, the cause of the fault can be checked. The automatic adjustment program can also be manually interrupted. The parameters measured during the automatic adjustment will be stored in EEPROM.
After successful automatic adjustment, the debugging is complete. Other parameter settings are not mandatory and can be set as needed!
