EEP‑F4901‑2026‑INST Revision: 1.0 Classification: Technical Application Note For exact pinout, always refer to the label

| Symptom | Likely Cause | Solution | |-----------------------------|-----------------------------------------------|----------------------------------------| | No click when 24V applied | Coil open, wrong voltage, or polarity reversed | Check voltage at A1-A2; test coil ohms | | Clicking but no load current| Welded or pitted contacts | Replace relay | | Coil gets hot (>80°C) | AC voltage on DC coil or overvoltage | Verify supply and coil rating | | Load stays on when coil off | Contacts stuck closed | Overload beyond 11A; replace relay | EEP‑F4901‑2026‑INST Revision: 1

| Mistake | Consequence | Fix | |---------|-------------|-----| | Using 18 AWG wire for 11A | Overheating, fire risk | Upgrade to 14–16 AWG | | No fuse on input | Damage to F4901 on short | Add 12A fuse in series with L | | Reversing input polarity (DC model) | Instant failure | Check + / - markings | | Enclosed box without vents | Thermal shutdown | Drill vents or add fan |

Wire the machine's power circuit through the NO or NC contacts depending on whether you want the machine to stop (break circuit) or start (complete circuit) when the relay is triggered. ShopBot Tools Critical Safety Checks Verification:
