4.2
Electrical installation for servo driven models
Note
● The frame of the weighfeeder needs to be grounded to ensure accurate signal processing
to the integrator.
● Refer to the electrical connection diagrams for several different S120 connection scenarios.
● The communication cable (green) and power cable (orange) must connect the servo motor
to the S120 to operate. The power (orange) cable has identifying markings on the shield to
ensure the connections match.
If the emergency stop is independent from the integrated safety feature on the control unit,
wire or jumper the digital inputs to complete the circuit.
