Troubleshooting for LT3300T Common Faults

Black screen on power-up: Verify DC24V ≥19.2V; backlight aging is a frequent failure for this model
Touch drift / no touch response: Analog resistive screen aging; touch panel can be replaced separately
No DIO output action: Distinguish Sink / Source, confirm common terminal wiring; check pulse/output assignment in program
Communication failure: Check COM DIP switch, protocol and station number; verify Ethernet IP and GP-Pro EX transfer key
Program loss: Backup battery failure; replace battery then re-download project + logic program

Typical Application Cases of Pro-face LT3300-T1-D24-K (HMI+PLC All-in-One)

Core advantages: 5.7″ screen + built-in 16DI/16DO, native pulse output & high-speed counter, expandable via EX modules; one software GP-Pro EX for both screen graphics and logic programming. Suitable for small & medium standalone machines, eliminates separate PLC, shrinks control cabinet and reduces wiring. K version is Sink output, compatible with most NPN sensors used domestically.

Case 1: Vertical Form-Fill-Seal Packaging Machine (Most Common)

Configuration: LT3300-T1-D24-K main unit + EXM-AMI4LT temperature module

Controlled objects: Servo film pulling, sealing heating, hopper feeding, photoelectric detection, color mark positioning, pneumatic gripper

Resource utilization: Native pulse output drives film feed servo; built-in high-speed counter reads color mark sensor; DI for material level, safety door, emergency stop; DO for solenoid valves and heating contactors

HMI screens: Bag length setting, production count, sealing temperature curve, fault alarm, recipe switching for multiple bag sizes

Communication: RS485 connected to temperature controllers; Ethernet uploads output and reject data to host PC

Benefits: Single unit handles HMI and motion logic for compact control cabinet; IP65 front panel for humid food workshop; product changeover via recipe recall without program modification

Case 2: Small Blow Molding / PET Bottle Blowing Machine

Configuration: LT3300-T1-D24-K + optional CA8-CANLT-01 CANopen master module

Control: Mold opening/closing, blow timing, heating zone temperature control, robot pick-up, low-pressure / high-pressure blow sequence

Highlights: CANopen module connects CANopen servos and IO slaves; high-speed counter reads encoder position; interlock logic for safety door and pressure protection

HMI screens: Blow pressure curve, heating temperature, cycle time, alarm log, manual debug page

Industry feature: Bulk export machines, fewer spare part types and simple maintenance

HMI screens: Test parameters, yield statistics, alarm history, barcode binding for cell ID

Features: Simple logic and short cycle, low cost, compact fixture layout for parallel test stations

General Selection & Operation Notes (K Version Focus)

K = Sink (NPN compatible, sinking output) : Direct match with most domestic NPN photoelectric and proximity sensors; select C version Source for PNP sensors
Max I/O scale: 16DI+16DO onboard, up to 3 external EX modules. Not suitable for high I/O count or multi-axis motion applications; use independent PLC + HMI instead
Pulse axis: Native pulse output for 1~2 axis simple positioning, not recommended for complex multi-axis motion
Software: GP-Pro EX handles both screen graphics and control logic; one single project file for download
EOL reminder: LT3300 discontinued; new projects use STC6300TA as replacement. Current demand is mostly spare parts and project migration for legacy machines

Unsuitable Scenarios for LT3300

Large conveyor lines, motion control over 10 axes, massive distributed I/O, complex MES interface

Safety PLC / PLd safety level applications (standard I/O does not meet safety rating)
