✅ Troubleshooting Steps:

Check for Obstructions:
- Inspect the press bar guide rails for debris, glue build-up, or foreign objects.
- Ensure no panel or loose parts are stuck under the bar.
Inspect Pneumatics or Motor Drive:
- If the press bar is pneumatic, check for proper air pressure.
- If motor-driven, check for motor load spikes or coupling misalignment.
Lubrication & Mechanical Inspection:
- Make sure the vertical guide shafts or rails are well-lubricated.
- Inspect the coupling unit for signs of wear, slippage, or physical damage.
Check Sensors and Limits:
- Ensure the upper/lower limit switches or proximity sensors are not misaligned or damaged.
- If the sensors are faulty, the machine may falsely detect resistance or misposition.
Reset the Alarm:
- Go to the “ALARMS” screen.
- Review the activation details and press RESET once the issue is resolved.
- Recalibrate the press bar movement if necessary (based on the machine manual).

🛠️ Preventive Tips:

Regularly clean the press bar mechanism.
Lubricate moving parts weekly.
Perform a weekly test cycle without material to detect resistance early.
Train operators to avoid loading panels too high or off-centre, which can overload the system.
