Error ID: 66049: Cyan cross valve front failed to close FB10000 Error Messages Troubleshooting One or more cross valves do not receive 24V 1. Change the cross valve state using Control Tools and check (feel or hear) if an air flow change occurs. 2. If air flow change occurs, this indicates that the valve is Ok and that it receives 24V. 3. If no air flow change occurs, check if this specific valve is properly fed with 24V. One or more cross valves are stuck or their sensor is faulty 1. After having checked that the air feed and the voltage to the valve are Ok, detect the first cross valve that shows error and remove its cover. 2. Check if the cross valve flag is moving when you give a change-state order. 3. If the flag does not move, then the cross-valve is stuck and should be removed. 4. If the cross-valve flag moves but the sensor does not change state - with the cross valves in the closed position, manually hide & reveal the optic sensor to see if it changes states. If it does not change states and it gets voltage then the sensor itself is faulty and should be replaced. Sensor electricity wiring no voltage 1. If there is a voltage change when you send an Open or a Close order, then the valve is faulty and should be replaced. Top 2. If the valve is ok and the problem persists, check the wiring to the Cross Valve. 3. If it gets voltage but does not change state, this indicates that the sensor is faulty and should be replaced.
