Error 204 occurs when the Mixmate system cannot detect a specific component (such as a valve, sensor, or inductor) on the communication network that it needs to perform a task.
You will receive Error 204 when the machine is unable to find a device on the CAN bus that is required to run the current operation. The CAN bus is the "nervous system" of your Mixmate, allowing the master controller to talk to all the different hardware parts. If one of those parts stops responding or loses power, the system triggers this error to prevent an incomplete or inaccurate mix.
The first step is to reboot the Mixmate hardware. Power the system down completely and then turn it back on. This forces the master controller to re-scan the network and attempt to re-establish a connection with all plugged-in devices.
Inspect the wiring throughout your setup. Ensure that:
All devices are fully plugged into the harness.
No cables have been pinched, cut, or frayed.
All components are receiving power (check for status lights on individual valves or modules).
Like other communication errors, 208 can be caused by improper electrical termination.
To test the resistance:
SHUT OFF ALL POWER to the Mixmate.
Locate the Power Module (the white box).
Using a digital multi-meter, measure the resistance between the GREEN and YELLOW wires.
Resistance Standards:
~60 Ohms: Ideal. (Two healthy terminators detected).
~120 Ohms: Faulty. (Only one terminator is working).
70–135 Ohms: Intermittent issues and 208 errors are very likely in this range.
<50 or >135 Ohms: The system will not function.
