Other Features:

Dimensions: Approximately 17.8 cm × 10.7 cm × 21.5 cm.

Shipping weight: 6 kg.

Symptom: No output, indicator lights off.

Troubleshooting Steps:

1. Verify the input power is normal. Use a multimeter to measure the input voltage and check if it falls within the allowable range (120/240V AC or 125V DC, 47 to 63Hz).

2. Check the power cord connection for looseness, open circuits, or short circuits.

3. If the input power and wiring are normal, the internal power circuit of the module may be faulty. Contact professional maintenance personnel or replace the module.

Symptom: Unstable output voltage, abnormal voltage, or no output.

Troubleshooting Steps:

1. Use a multimeter to measure the output voltage and check if it stabilizes around 24V DC. If the voltage deviates significantly, inspect the load for short circuits or overloads. Remove the load fault and retest.

2. Check the output wiring for looseness, open circuits, or short circuits to ensure reliable connections.

3. If the load and wiring are normal, the module’s output circuit may be faulty. Consult professional maintenance or replace the module.

Symptom: Excessively high surface temperature, possibly accompanied by unusual odors or performance degradation.

Troubleshooting Steps:

1. Ensure the installation environment is well-ventilated and has sufficient heat dissipation space, preventing the module from operating in high-temperature or enclosed environments.

2. Check if the module’s load exceeds its rated capacity. If so, reduce the load or replace the module with a higher-power model.

3. Inspect the cooling fan (if applicable) for normal operation. Clean or replace the fan if faulty.

Symptom: Poor communication with other devices, such as failed data transmission or frequent communication errors.

Troubleshooting Steps:

1. Check the communication wiring for correct and secure connections, as well as damage or poor contact.

2. Verify that the communication protocol settings (including baud rate, data bits, parity bits, etc.) match those of the connected device.

3. Inspect the communication interfaces of the module and connected device for damage. Replace the corresponding interface module or device if needed.

4. Check the network configuration (e.g., IP address, subnet mask, gateway) to ensure compatibility with the network environment.

Symptom: The module or related system emits an alarm signal.

Troubleshooting Steps:

1. Obtain specific alarm information via the system management software or module indicator lights to determine the alarm type and related devices.

2. Based on the alarm prompt, inspect corresponding hardware, wiring, and configuration parameters to identify the fault cause.

3. Refer to the module’s technical manual and relevant documents to understand the meaning and solutions for specific alarm codes.
