• Confirm load-cell type, impedance and total sensor quantity before connecting the weighing system.
• Disconnect power before wiring load cells, relays, external inputs, communication interfaces or analog outputs.
• Use the specified six-wire load-cell connection and carefully verify excitation, signal and sense terminals.
• Complete zero and span calibration before connecting the controller to automatic production equipment.
• Test all input and relay output functions without load before starting automatic operation.
• Set target weight, pre-act value, upper and lower limits and delay parameters according to the actual process.
• Use external contactors or suitable power-control devices when switching loads exceeding the relay contact rating.
• Route load-cell and communication cables away from motors, frequency converters and high-current power cables where possible.
• Install the controller in a dry control cabinet and protect it from dust, condensation and direct washdown.
• Back up important calibration and control parameters before instrument replacement or major servicing.

Q: What is the main application of the C8+?
A: It is designed for industrial weighing and automatic control applications such as batching, quantitative filling, sorting and automatic material discharge.

Q: How many load cells can be connected?
A: The standard specification supports up to eight 350-ohm analog load cells.

Q: How fast is the weight conversion?
A: The high-speed A/D system can process up to approximately 80 conversions per second.

Q: Can the C8+ automatically control feeding equipment?
A: Yes. Three relay outputs can be configured to control compatible feeders, valves, actuators or other external equipment through an appropriate control circuit.

Q: Can it control more than one material?
A: In addition or subtraction batching modes, one or two materials can be configured according to the application.

Q: Can the controller communicate with a computer or PLC?
A: Yes. Serial communication and optional analog signal outputs allow integration with compatible industrial control and data-management systems.

Q: Does it support 4–20 mA output?
A: Yes. Isolated analog-output configurations can provide 4–20 mA and other selectable current or voltage signals.

Q: Can it be used in livestock feed production systems?
A: Yes. It is suitable for feed batching, powder dosing, quantitative filling and other automated weighing processes used in livestock and feed-production projects.
