Why is the VAT Control Unit PRESSURE CONTROL not optimal?
PRESSURE CONTROL might not be optimal due to several reasons. Perform the setup procedure completely. Ensure that you have performed LEARN and ZERO before LEARN. If LEARN was interrupted, repeat it with stable gas flow. Tune the valve for your application. Use a sensor with a suitable range, ensuring the controlled pressure is between 3% and 98% of the sensor's full scale. Also, make sure a shielded sensor cable is used to minimize noise.
What to do if VAT 61228-KAGG-0002 display shows «E 40»?
If the display shows «E 40» on your VAT Control Unit, indicating a fatal error related to motor driver failure, replace the control and actuating unit according to «Maintenance procedure».
What does error E21 mean on VAT 61228-KAGG-0002 display?
If your VAT Control Unit displays 'E 21' and the position '009999' (fatal error - rotation angle of valve plate limited during power up), check if the valve plate is centric adjusted, if the valve unit is heavily contaminated or if the valve plate is mechanically obstructed. Adjust the valve plate according to the maintenance procedure, clean the valve unit, and resolve any obstructions. Reset the control unit by cycling the power off and on, or send a reset command locally via the service port with CV/CPA/Service Box2.
