Troubleshooting and error codes
| Problem | Possible Cause | Corrective Action |
|---|---|---|
| 1. No power to melter | Problem with customer power source | Check all three phases at terminal block |
| No voltage plug installed | Install correct voltage plug | |
| Loose/disconnected cables | Check cable between transformer and J1 on main board | |
| Check connections between transformer service terminal block and J2 on power distribution module | ||
| Blown fuse | Check fuses F3, F4, F5, and F6 | |
| Problem with transformer | Check voltage into primary of transformer(s) and voltage at secondaries. | |
| 2. Tank and/or manifold not heating, but power to melter | Programming/control issue | Turn heaters on/check that tank set-point is correct (not 0) |
| Loose/disconnected cables | Check connection at J9 on main board | |
| Check connections along heater harness (intermediate connections, terminals of heaters, connection back to J3 on power distribution module | ||
| Problem in heater | Check for open or short. Cold resistance values are: Manifold 175 to 203 ohms Tank P4 - 175 to 203 ohms P7 - 145 to 169 ohms P10 - 145 to 169 ohms | |
| Blown fuse | Check F1/F2 on main board | |
| Power problem | Check all three phases at terminal block | |
| Problem with power distribution module | Replace module | |
| 3. Fuse(s) fail frequently | F1 or F2 fault: short circuit in heater or harness | Locate and correct short |
| F3, F4, F5, or F6: Transformer is overloaded | Verify that total hose/gun power does not exceed capability of transformer | |
| 4. F3 fault on tank or manifold | Shorted TRIAC(s) | Replace power distribution module |
| Noise problem | Isolate sources of noise, change phases of incoming supply, or add filter/snubber to incoming supply line |
