Fault Screen "Vessel Overtemp"
Fault Screen "Vessel Overtemp"
The vessel temperature has exceeded the maximum limit.
Possible Causes:
The solution level is low in the vessel, but the level sensor is indicating full. The level sensor has two main components that work together. These components are a Level Sensor Module and the Glass Sensor Tip. Refer to and follow the section on testing and training the Level Sensor in A2000 Service Procedure 10 for SICK Level Sensor (Blue Model) or see A2000 Service Procedure 7 for Analog Level Sensor (Black Model).
If the level sensor is not working, it may need replacing. See A2000 Service Procedure 11 for the SICK Level Sensor (Blue Model) or see A2000 Service Procedure 9 for the Analog Level Sensor Module (Black or gray model) to replace the Glass Tip and Fiber Optic Cable Assembly (A32).
The vessel is overfilled with solution. The Level Sensor is not detecting solution. See A2000 Service Procedure 10 for SICK Level Sensor (Blue Model) or see A2000 Service Procedure 7 for Analog Level Sensor (Black Model).
The motor stopped turning. Check the Packing Nut to make sure it is not over tightened. See A2000 Service Procedure 1.
The motor needs to be replaced. See A2000 Service Procedure 23.
Fault Screen "Open Failure"
Fault Screen "Open Failure"
The drain valve has been told to open but after 30 seconds the drain open switch has failed to open the drain.
Possible Causes:
Wires on the drain valve have become disconnected. Unplug the instrument, check the drain valve and reattach any loose wires. Check blue wire (I1), yellow wire (I2), black wire (4),and red wire (4). See A2000 Service Procedure 26.
The drain valve or the drain open/close switch is not operating. When the instrument is turned on, the red light on relay #6 should be lit (See A2000 Service Procedure 26). At that time you should hear the drain valve opening. After 10 seconds, the drain valve will close. If the drain valve is not operating, it will need to be replaced. If the drain valve is operating but does not stop, then the open/close switch is not being detected by the computer. Unplug the instrument and check the drain valve for any loose wires.
The instrument will not turn on.
The instrument will not turn on.
Possible Causes:
The power cord is not plugged into the unit or power source.
The main power switch is not turned on.
One of the system circuit breakers (fuses) needs to be replaced. See A2000 Service Procedure 25.
