Error 201 is triggered when the Mixmate system expects to be measuring product movement but the flowmeter is reporting zero activity.
You will receive Error 201 when the master controller has commanded a mix to start (valves open, pumps requested), but the designated flowmeter is not sending any pulses back to the system. This stops the process to prevent the pump from running dry or the carrier from being miscalculated.
Work through the following checklist to identify where the blockage or failure is occurring:
Valve Operation: Physically verify that the valves feeding this flowmeter are actually opening. A stuck actuator or broken linkage will prevent flow.
Pumps and Airlocks: Ensure your pumps are turned on and primed. If the pump is spinning but nothing is moving, you may have an airlock in the plumbing.
Filters/Strainers: Check any inline filters or strainers. A plugged screen will completely choke off the flow.
Flow Direction: Check the arrow on the side of the flowmeter body. Ensure the meter is installed so that the product flows in the direction of the arrow.
Depending on whether you are using a Gear Meter or a Mag Meter, check for these common issues:
Gear Meters: If the gears are stuck due to dried chemical or debris, the meter cannot pulse. Verify that the gears spin freely by hand.
Mag Meters: If you are using a Mag Meter, a film or buildup on the internal sensors can prevent the meter from "seeing" the flow. Clean the internal bore with a soft cloth and mild detergent.
Power to Meter: Verify that the flowmeter is receiving power. Look for any indicator lights on the meter itself or check the connection at the CAN bus.
Cabling: Ensure the cable connecting the meter to the system isn't pinched or disconnected.
