If your VAT Control Unit displays 'SR' (Service Request), it indicates that the valve unit may be heavily contaminated or the gate seal is sticking. Clean the valve unit according to maintenance procedures. Then, reset the control unit either by cycling the power off and on, or by sending a reset command locally via the service port with CV/CPA/Service Box2.
What to do if VAT 61228-KAGG-0002 Control Unit display shows «D 0»?
If the VAT Control Unit displays «D 0», which indicates the Motor Interlock is open, ensure that power is supplied to the motor.
Why is PRESSURE CONTROL not optimal on VAT 61228-KAGG-0002?
To optimize PRESSURE CONTROL on your VAT Control Unit, perform the setup procedure completely, perform LEARN, and ensure ZERO was performed before LEARN. Repeat LEARN if it was interrupted or if the gas flow was unstable. Tune the valve for your application and verify the sensor range is suitable. Also, ensure a shielded sensor cable is used. These steps address potential issues such as incomplete setup, improper LEARN execution, unstable gas flow, incorrect tuning, unsuitable sensor range, or noise on the sensor signal.
What does 'M100' on the VAT 61228-KAGG-0002 Control Unit display mean?
The display showing 'M100' indicates that maintenance mode is active. This is because pin 13 of the service connector is connected to ground, which will cause the plate to open and block further movement.

Why pressure reading is wrong on VAT Control Unit?
To fix a pressure reading that is wrong or negative on your VAT Control Unit, check the electrical connections, verify the valve version and configuration, perform ZERO after reaching base pressure, and verify the sensor supply voltage. The issue may stem from unconnected sensors, an incorrect sensor version, an unperformed ZERO, or insufficient sensor power.
Why ZERO does not work on VAT Control Unit?
If ZERO does not work on your VAT Control Unit, open the valve and bring the chamber to base pressure before performing ZERO. Also, ensure that ZERO is enabled.
What to do if pressure is not ‘0’ after ZERO on VAT Control Unit?
If the pressure is not ‘0’ after performing ZERO on your VAT Control Unit, wait until the sensor voltage stabilizes before performing ZERO. Ensure the valve is open and the system is pumped to base pressure before performing ZERO. If the sensor offset voltage exceeds ±1.4V, replace the pressure gauge.
