The 853 Series valves use the SAE J1939 protocol to communicate directly with the Mixmate network. Unlike standard valves, these provide internal diagnostics and precise position sensing.
The top of the valve features a multi-color LED indicator that provides immediate feedback on the valve's status:
| LED Color/Pattern | Valve Status | Action Required |
| Green (Steady) | Valve is fully Open | Normal operation. |
| Yellow (Steady) | Valve is fully Closed | Normal operation. |
| Yellow/Green (Blinking) | Valve is Moving | Normal during transition. |
| Red (Steady) | Motor/Mechanical Error | Check for blockages or internal gear failure. |
| Blue (Steady) | Communication Active | Valve is receiving CAN-bus data. |
| Magenta (Blinking) | ID Acquisition Mode | The valve is waiting to be assigned an address. |
In the event of a power failure or system error, the valve can be operated manually:
Locate the metal pin on the actuator neck.
Press and hold the pin to disengage the motor gears.
Turn the handle/knob to the desired position.
Note: Ensure the pin "clicks" back into place once power is restored to allow the motor to take back control.
To maintain a clean data signal on the CAN-bus, follow these installation rules:
Power Supply: The valve requires a stable 12V DC supply. Use the same 8-gauge battery connection logic we established for the main modules.
CAN Line: The total length of the CAN-bus line should not exceed 40 meters (approx. 131 feet).
Pinouts:
Pin 1: Ground (Black)
Pin 2: +12V Power (Red)
Pin 3: CAN Low (Green)
Pin 4: CAN High (Yellow)
Max Pressure: Depending on the model (3-way vs 2-way), ratings typically range from 10 to 40 bar (145 to 580 PSI). Check the side of the valve body for your specific rating.
Operating Temperature: 0°C to +60°C (32°F to +140°F).
Actuation Time: Typically 0.6 to 1.5 seconds depending on the ball size and gear ratio.
Address Limit: Up to 20 valves can be addressed on a single CAN-bus branch.
Winterization: If the machine is stored in freezing temperatures, the valve must be cycled while the system is empty to ensure no liquid is trapped inside the ball.
Cleaning: Use only clean water or mild detergents. High-pressure washers should be kept at a distance of at least 30 cm (12 inches) from the seals and electrical connectors.
If your 853 Series valve is not responding or shows a Red LED, count the number of blinks to identify the issue.
If the Red LED is Steady ON and the valve does not respond:
Power Issue: Check for a disconnected power cable or a blown fuse. Ensure your 8-gauge battery lines are secure.
Wiring/Harness Error: Verify the 4-pin M12 connection is hand-tight and free of moisture.
CAN-Bus Termination: Ensure terminating resistors are present at both ends of the chain. Without these, the signal is "noisy" and the valve will ignore commands.
Hardware Failure: If wiring and power are confirmed good, the internal hardware may be damaged. Contact your service center.
If the Red LED is Blinking, count the number of pulses between pauses to diagnose the specific fault:
| Blinks | Problem | Possible Cause | Solution |
| 2 | No Response | Memory/Factory Data Error | Reset to default values and save. |
| 3 | Won't Stop at Point | Calibration Error | Calibration was not performed; contact Service Center. |
| 4 | Won't Stop at Point | Overheating | Move valve away from heat sources (engines/exhaust). |
| 5 | Valve Works, but Blinks | Voltage Issue | Battery is defective, voltage is too low, or you are incorrectly using a 24V system. |
| 6 | Won't Stop at Point | Failed Calibration | Internal sensing error; contact Service Center. |
| 7 | Won't Stop at Point | Addressing Error | Commands sent to wrong address or wrong ID assigned. Repeat ID acquisition. |
| 8 | No Response | Motor Control Error | Restart the valve (power cycle). If it persists, internal circuit is failed. |
| 9 | No Response | Mechanical Block | Gear motor or pin is physically blocked. Check for debris in the ball or check the manual override pin. |
If the valve behaves sluggishly or triggers Blink Code 9:
PWM Check: Verify the PWM (Pulse Width Modulation) settings in the Mixmate module configuration are correct for the motor control.
Harness Integrity: Ensure the harnesses are the correct gauge for the distance. Voltage drop over long, thin wires is a common cause of motor control failures.
If the valve is physically stuck (Code 9):
Disconnect power.
Press the Manual Override Pin on the neck of the actuator.
Manually rotate the ball to ensure no stones or chemical buildup are jamming the movement.
If the motor is "humming" but not moving, the internal gear motor is likely broken and requires replacement.
