On-site Quick Diagnosis Procedure
- Power Check
Measure input voltage to ensure it stays within 19.2~28.8VDC.
Check power indicator (normally steady green).
Confirm stable DC24V output from power module.
- Display & Touch Test
Check backlight; troubleshoot CCFL if no backlight.
Run touch calibration program to verify touch accuracy.
Check for incomplete display, screen distortion or black screen.
- Communication Test
Test main and expansion serial ports with serial debugging tool.
Perform ping test to check Ethernet connection.
Insert a functional CF card to verify read & write capability.
- System Function Verification
Check run indicator (normally flashing green).
Test AUX outputs: Run signal, alarm signal and buzzer.
Trigger remote reset via AUX input for function verification.
- Selection Guidelines & Quick Reference Rules
- Three Key Selection Factors: Screen size (10.4-inch), Power type (DC24V), Communication requirements (Ethernet + dual serial ports)
- Replacement Rule: Replace GP2500-TC41-24V with GP4501T-ADW (same cutout) or GP4501T-MD (2-point touch supported); Pay attention to panel cutout differences.
- Maintenance Tips
Replace lithium battery every 5 years; shorten cycle if ambient temperature exceeds 40℃.
Replace CCFL backlight after 50,000 service hours.
Clean screen regularly with dedicated detergent and soft cloth.
- Upgrade & Migration Guide
Project Conversion: Use GP-Pro EX to convert GP-PRO/PBIII projects.
Hardware Replacement: Confirm panel cutout; use accessory CA4-ATM10-01 if needed.
Communication Configuration: Reset communication parameters on new unit for PLC compatibility.
