6. Front Panel & Operation
6.1 Front Panel Layout
Tri‑Colour RUN LED (EtherCAT & Service State):
Off: INIT or no power.
Slow blinking green: Pre‑operational.
Slow blinking orange/red: Pre‑operational (module selected).
Single flash green: Safe‑operational.
Single flash orange/red: Safe‑operational (module selected).
EtherCAT Port: For connection to AWC 500 controller.
6.2 Startup & Configuration
Power On: Apply 24 VDC; RUN LED lights (off → blinking green).
EtherCAT Connection: Connect cable to AWC 500; LED blinks green (pre‑operational).
Module Configuration: Use DEIF Utility Software to set AI type, scaling, and DO logic.
System Recognition: AWC 500 detects IOM5‑1; LED flashes green (safe‑operational).
Parameter Setup: Configure fault thresholds, filter settings, and safety interlocks.
Operation: RUN LED single flash green = normal operation; I/O active per system logic.
7. Safety Precautions
High Voltage Hazard: Only qualified electricians may install/service; disconnect all power before wiring.
ESD Risk: Static electricity can damage the PCB; use anti‑static protection when handling.
Relay Output Caution: DO relays switch high voltages; ensure load ratings are not exceeded.
No Unauthorised Modification: Do not open the enclosure; tampering voids the warranty.
Environmental Limits: Do not operate outside –40°C to +75°C; avoid condensation.
8. Maintenance & Storage
8.1 Regular Maintenance (Every 6 Months)
Visual Inspection: Check for loose terminals, damaged wiring, or corrosion.
Cleaning: Wipe the front panel with a dry cloth; do not use liquid cleaners.
LED Check: Verify RUN LED operates correctly per EtherCAT state.
Channel Test: Use DEIF Utility Software to test AI/AO/DI/DO/FI accuracy and functionality.
Cable Tightness: Re‑tighten terminals to 0.8–1.0 Nm.
8.2 Storage Guidelines
Condition: Store in original anti‑static packaging at 10–30°C, 30–70% RH.
Environment: Keep dry; avoid direct sunlight and extreme temperatures.
Duration: Shelf life ≤2 years; inspect for ESD damage before use if stored longer.
9. Troubleshooting
| Fault Phenomenon | Possible Cause | Solution |
|---|---|---|
| RUN LED Off | No 24 VDC supply / blown fuse | Check power wiring; replace 3 A fuse |
| RUN LED Blinks Green Continuously | EtherCAT communication fault / wrong node address | Verify cable; check address in AWC 500 |
| RUN LED Blinks Red/Orange | Module hardware fault / overvoltage | Cycle power; contact DEIF support |
| Analogue Input Inaccurate | Software config mismatch / noisy signal | Correct AI type in Utility Software; use shielded cables |
| Frequency Input No Reading | Incorrect voltage range / wiring fault | Verify FI input voltage (24 VDC); check terminals 32–35 |
| Digital Output Not Activating | Overload / wiring fault | Check load; verify DO terminal connections |
