Frequently Asked Questions
Q1: The power indicator does not light up and the board is unresponsive after power-on.A: ① Verify the 24V DC input is normal and measure whether the voltage is within 21.6V–26.4V.② Check for reversed wiring or poor contact on the power terminals, as well as terminal oxidation and looseness.③ Inspect whether the board fuse is blown and replace it with a fuse of the same specification.④ If all checks are normal, the board’s switching power supply may be faulty; please contact ABB after-sales for inspection.
Q2: Large deviation and unstable data of signal input and output.A: ① Avoid laying signal cables in parallel with power cables; confirm single-end grounding of the shielding layer and re-standardize the wiring layout.② Calibrate signal parameters and measure standard signals (e.g. 4–20mA) with a multimeter.③ Check the wiring terminals for oxidation and looseness, then retighten them firmly.④ Install a signal filter if the site is subject to severe electromagnetic interference.
Q3: Communication failure; the host computer cannot detect the board.A: ① Check the communication cable for damage and poor connection, and ensure reliable grounding of the shielding layer.② Keep communication parameters (address, baud rate, protocol) consistent with the host computer; default baud rate is 9600bps.③ Confirm a 120Ω terminal resistor is installed at both ends of the communication bus.④ Restart the board and host computer. If the fault persists, the communication chip may be damaged.
Q4: Frequent alarms and flashing indicators during board operation.A: ① Check if the ambient temperature exceeds 45℃, ensure good ventilation of the control cabinet, and clean dust from cooling fans.② Inspect the board for moisture and dust accumulation, and clean it with anhydrous alcohol.③ Detect excessive fluctuation of supply voltage and install a regulated power supply if necessary.④ For overcurrent/overvoltage alarms, check external loads for short circuit and overload.
Q5: The system fails to recognize the new board and data is lost after replacement.A: ① Back up parameters of the original board before replacement; download and calibrate parameters for the new board.② Confirm the model of the new board is 1KHL015008R0001.③ Ensure the gold fingers are fully inserted into the slot without looseness or oxidation during installation.④ Restart the system for re-detection; contact ABB technical support if the problem remains unsolved.
Q6: Short service life and prone to aging and damage.A: ① Keep the installation environment free of corrosive gas and heavy dust, and perform regular three-proof maintenance.② Avoid long-term overload operation and strictly keep the supply voltage within the rated range.③ Regularly inspect capacitors and chips for bulging and discoloration, and replace aging components in a timely manner.④ Adopt original ABB parts instead of low-quality alternative products.
