Operational errors
| Error code or LED flashes | Error type | Description |
|---|---|---|
| 6 | Thermostat failure | (If the NTC thermistor is short-circuit or has no connection). |
| 5 | Thermal cut-out of electronic unit | (If the refrigeration system has been too heavily loaded, or if the ambient temperature is high, the electronic unit will run too hot). |
| 4 | Minimum motor speed error | (If the refrigeration system is too heavily loaded, the motor cannot maintain minimum speed at approximately 1,850 rpm). |
| 3 | Motor start error | (The rotor is blocked or the differential pressure in the refrigeration system is too high (>5 bar)). |
| 2 | Too many start attempts or fan over current | (Too many compressor or fan starts in short time or fan current higher than 0.5A avg). |
| 1 | Battery protection cut-out | (The voltage is outside the cut-out setting). |
Wiring diagrams
Wiring diagrams for DC applications are provided, illustrating connections for electronic units, power supply, and accessories like Secop Gateway, NTC resistors, and mechanical thermostats.
