Decastar 150e: Manual
The Decastar 150e manual includes several pages of parameter tables. Here is a digest of the most critical ones:
Before diving into the manual’s contents, it is essential to understand the device. The Decastar 150e is a digital process indicator and controller, typically manufactured by LAUMAS Elettronica, an Italian leader in industrial weighing technology. It is designed for:
The "150e" model is known for its compact DIN size, bright LED display, and modular I/O options. Because of its versatility, the manual is notoriously dense—which is why this breakdown is so valuable. decastar 150e manual
Tip from manual: If you see
ERR31during calibration, check the load cell signal (mV/V) – it is likely too low or too high.
| Fault Code | Display | Likely Cause | Solution |
|------------|---------|--------------|----------|
| E-01 | OC | Overcurrent at constant speed | Check motor insulation; increase decel time |
| E-02 | OU | Overvoltage (DC bus > 400V) | Braking resistor needed or lengthen decel |
| E-03 | LV | Undervoltage (input power dip) | Verify mains stability; check L/N connections |
| E-04 | OH | Overheat (heatsink > 85°C) | Clean fan; check mounting clearance |
| E-05 | SC | Short circuit (U/V/W) | Disconnect motor – if fault remains, replace drive |
| E-10 | CE | Communication error (RS485) | Check Modbus wiring and address settings | The Decastar 150e manual includes several pages of
Reset: Press STOP/RESET twice or cycle power after 1 minute.
When your Decastar 150e behaves erratically, the manual’s error code section is your first stop. Below are frequent codes and solutions. The "150e" model is known for its compact
| Error | Meaning | Solution (from manual) |
|-------|---------|------------------------|
| ERR01 | EEPROM failure | Replace mainboard. Attempt reset via r.St in Tech Menu. |
| ERR03 | A/D converter not responding | Check power supply (minimum 12V DC). Check internal ribbon cable. |
| ERR05 | Weight exceeds max + 9d | Remove load. Check for mechanical binding. |
| ERR08 | Underload (negative overload) | Calibration zero lost. Perform C.IN again. Check load cell wiring (Excitation +/-). |
| ERR31 | Calibration weight error | Applied weight < 1% of full scale. Use larger test weight. |
| Lo BAT | Low battery (if backup option fitted) | Replace internal battery or connect mains. |
If you see "----" flashing, the ADC is saturated—immediate check load cell input (typically > 3mV/V or broken cable).
