Wiring Best Practices

This guide explains how to connect your Mixmate components and get power to the system safely.

Important: This step is only about the physical wiring. You will not connect the app or run a mix yet.

Before You Begin

• Ensure the machine is installed and plumbing is secure.

• Safety First: Make sure all power sources are disconnected before plugging in or unplugging any cables.

1. Connecting Components (The CAN Bus)

Mixmate components talk to each other using a system called the CAN Bus. You must connect them correctly for the system to work.

• Power OFF: Always connect components while the power is off.

• Daisy Chain: Connect the components in a single, continuous line (like a chain). Do not create "branches" or loops.

• Terminators (Critical): You must install exactly two terminators—one at the very beginning of the chain and one at the very end.

  • Tip: If you put terminators in the middle, or if you use more than two, the system will not work.

2. Choosing a Power Method

You can power Mixmate using a 12V Battery (most common) or a Power Supply. Choose one method below.

Option A: Battery Power (Recommended)

If you use a battery, it must be strong enough to handle the valves opening and closing.

• Battery Type: Use a Group 31 battery with at least 960 CCA (Cold Cranking Amps).

• Charging: You need a reliable way to keep the battery charged. Use a battery maintainer rated for at least 8 Amps, or connect it to a vehicle's charging system.

• Voltage Check:

  • 12.7V - 13.8V: Healthy / Normal.

  • Below 11.7V: Dead battery.

  • Note: Always check voltage at the battery and at the Mixmate terminals. If the numbers are different, you have a bad wire connection.

Option B: Power Supply

Mixmate draws a lot of power (up upwards of 100 Amps) for short bursts when valves open. If you use a power supply, it must be heavy-duty.

• Requirements: It must provide at least 60 Amps at 13.5 Volts DC.

• Stabilization: We strongly recommend adding a capacitor or a small buffer battery. Most standard power supplies cannot handle the sudden surge of current without one, which causes the system to reset or error out.

3. Wiring and Grounding

Bad wiring is the #1 cause of issues. Follow these rules to avoid problems:

• Wire Size: Use 8-gauge wire (approx 10mm²) or thicker.

• Wire Length: Keep power wires short—under 60 inches (1.5 meters) is best.

• Grounding: Connect the ground wire directly back to the power source. Do not rely on the chassis or frame for grounding.

4. Power On

Once everything is wired and double-checked:

1. Turn on the main power switch.

2. The system should power up smoothly without error lights.

3. If it powers up correctly, you are ready for the next step.
