The "Solder Rollout Motor Over Torque Alarm" indicates the rollout motor has an over-torque conditions. A current sensor (CT-07) measures the amperage from the motor’s dedicated 24 VDC power supply. If the current exceeds the set threshold, CT-07 activates the coil of relay CR-10, closing its contacts and sending a signal to the system’s computer. The alarm is displayed on the Digital I/O Screen in the system software, enabling operators to address potential issues promptly to prevent motor damage and safety issues.
Please Note: The I/O number mat be different depending the on the model of the machine.
To troubleshoot the Solder Rollout Motor Over Torque Alarm, follow these steps based on the provided information:
- Verify Rollout Stand and Tracks Alignment:
- Ensure the rollout stand and tracks are level. The pot should move smoothly without navigating inclines or declines, as uneven surfaces can increase motor torque and trigger the alarm.
- Check Transfer to Rollout Stand:
- Confirm the tracks align properly during transfer to the rollout stand. Misalignment can cause the pot to stall, increasing motor current and triggering the alarm.
- Inspect Tracks for Debris:
- Check for solidified solder or other debris on the tracks. Clear any obstructions to ensure smooth pot movement, as debris can increase resistance and motor torque.
- Inspect Wiring Connections:
- Verify all wiring connections to the motor, current sensor (CT-07), and relay (CR-10) are secure and tight. Loose connections can cause erratic current readings, falsely triggering the alarm.
- Verify CT-07 Current Threshold Setting:
- Check the "I" setting on CT-07, which determines the trip point for over-torque detection. Ensure it’s set between 20–25% as recommended. For testing, slightly increase the setting if needed, but avoid excessive adjustments to prevent motor damage.
- Monitor Alarm on Digital I/O Screen:
- Observe the Digital I/O Screen in the system software for alarm status. Note the specific I/O number associated with the alarm, as it may vary depending on the machine model.
- Additional Notes:
- If the alarm persists after verifying the above, inspect the motor and 24 VDC power supply for potential issues, such as motor wear or power supply instability.
By systematically addressing these points, you can identify and resolve the cause of the over-torque alarm, ensuring safe operation. If further assistance is needed, consult the machine’s manual for model-specific I/O details or contact technical support.
