As we all know, ABB TZIDC intelligent electric valve positioner is a digital intelligent electric valve positioner owned by ABB. It is mainly suitable for single and double acting, straight stroke and quarter-turn actuators. Support Hart communication. ABB TZIDC intelligent electrical positioner, due to its vibration resistance, can still provide reliable operation under 10G 80HZ vibration conditions, so it is widely used. After we bought the new ABB TZIDC intelligent electrical valve positioner, we conducted preliminary debugging on it. So today, the technical editor of Xi'an Pride Instruments will introduce to you the debugging steps of the ABB TZIDC intelligent electrical valve positioner, hoping to help the majority of users. Debugging steps: 1. Before connecting the air source, vent the air source pipe for a period of time to eliminate dust, impurities, water, oil, etc. that may be present in the pipeline. It is recommended that the venting time be 30 minutes. You can check the quality of the air source by hand or with white paper or white cloth. statement: If the positioner is damaged due to dust, impurities, water, oil, etc., ABB will not provide warranty. Check whether the pressure behind the pressure reducing valve meets the nameplate parameter requirements of the actuator (the maximum air supply pressure of the positioner is 6 BAR, but the actual air supply pressure must refer to the maximum allowable air source pressure of the actuator). 2. Connect the 4---20mA input signal. (The working power supply of the positioner is taken from the input signal and powered by DCS two-wire system. The voltage directly applied to the positioner cannot exceed 30V/50mA, otherwise the positioner circuit may be damaged). 3. Check the installation angle of the position feedback rod (if the positioner and actuator are supplied as a whole, the installation and debugging has been completed by the actuator supplier, you only need to check and confirm, this step is not necessary): •Press and hold the MODE key. •And click the ⇧ or ⇩ key at the same time until the operating mode code 1.3 is displayed. •Release the MODE button. •Use the ⇧ or ⇩ key to operate the actuator to the two end positions respectively, and record the two end angles. The two angles should comply with the following recommended angle range (minimum angular displacement 20 degrees, no strict symmetry is required). The straight stroke application range is within -28º---+28º. The application range of angular travel is within -57º---+57º. The full stroke angle should be no less than 25º. If the angle does not meet the above requirements, you need to adjust the installation position of the feedback lever, coupling or positioner to make the angle value meet the above requirements. 4. Start the automatic adjustment program (it is best to re-adjust through this program after the actuator or valve is installed in the system): Method 1: For straight stroke valves • Press and hold MODE key for 5 seconds until “ADJ_LIN” • Release the MODE button • Press and hold the MODE button again until the counter on the display counts down to 0 • Release the MODE button, and the automatic adjustment program starts running (the display shows the program statement number in progress). •The automatic adjustment process takes about 5 minutes. After successful completion, the positioner will automatically store the parameters obtained by the above automatic adjustment and automatically switch the control mode to 1.1 CTRL._FIX method 2: For quarter-turn valves • Press and hold the ENTER key for 5 seconds until “ADJ_ROT” • 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 starts running (the display shows the program statement number in progress). •The automatic adjustment process takes about 5 minutes. After successful completion, the positioner will automatically store the parameters obtained by the above automatic adjustment and automatically switch the control mode to 1.1 CTRL._FIX. If a fault is encountered during the automatic adjustment process, the program will be forced to terminate and a fault code will be displayed. According to the fault code, the cause of the fault can be checked. You can also forcefully interrupt the automatic adjustment process. The parameters measured during the automatic adjustment are stored in the EEPROM. After the automatic adjustment is successful, the debugging is completed. Other parameter settings are not necessary and can be set as needed!
