Wiring Conversions

Weigh-Tronix ↔ Dinamica Generale

The SPM load cell connectors for Weigh-Tronix and Dinamica Generale are physically interchangeable, but the internal wire colors are different. Use the following mapping:

Function	Weigh-Tronix	Dinamica Generale
Input +	Green	Red
Input -	Black	Black
Output +	White	Green
Output -	Red	White

Dinamica Generale ↔ Digi-Star

When connecting a Dinamica Generale load cell to a Digi-Star system (or vice versa), the white and green wires must be swapped to ensure the correct polarity. If not swapped, the scale will display a negative weight.

Function	Digi-Star	Dinamica Generale
Input +	Red	Red
Input -	Black	Black
Output +	White	Green
Output -	Green	White

Weigh-Tronix ↔ Digi-Star

When connecting a Weigh-Tronix load cell to a Digi-Star system, follow this mapping:

Function	Weigh-Tronix	Digi-Star
Input +	Green	Red
Input -	Black	Black
Output +	White	White
Output -	Red	Green

Troubleshooting

If the scale shows “out of range” or reads negative, re-check wire mapping against the correct table.
Inspect connectors for physical damage before splicing.
Always solder and heat-shrink splices to prevent corrosion and maintain signal quality.
If swapping brands and the reading is unstable, verify that all connections are secure and that there is no moisture intrusion in the cable.
