If the VAT Control Unit ZERO does not work, OPEN the VALVE and bring the chamber to base pressure before performing ZERO. If ZERO is disabled, enable it, referring to «Valve configuration» for details.
What does error E20 mean on VAT 612 display?
If the VAT Control Unit display shows 'E 20' and position '009999' (fatal error - limit stop of valve unit not detected), ensure the clamp coupling screw is tightened. Refer to the maintenance chapter for detailed instructions. A RESET or restart of the valve is then necessary.
What does D 0 mean on VAT 612 display?
If the VAT Control Unit display shows 'D 0' indicating the Motor Interlock is open, ensure that power is supplied to the motor to allow for operation. Refer to the electrical connection details for guidance.
What does error E40 mean on VAT Control Unit display?
If the VAT Control Unit displays 'E 40' and position '009999' (fatal error - motor driver failure detected), replace the control and actuating unit according to the maintenance procedure.
What to do if my VAT 612's Network Status LED is flashing red (time out)?
If the Network Status LED is flashing red, it indicates a time-out. Reestablish I/O connections to resolve this issue.
Why does my VAT 612 Control Unit display «E 21» error?
If the VAT Control Unit display shows «E 21» because the valve plate is not centric adjusted, adjust the valve plate according to «Maintenance procedure». If the valve unit is heavily contaminated, clean it according to « Maintenance procedure ». If the valve plate is mechanically obstructed, resolve the obstruction. Alternatively, reset the control unit by cycling the power (OFF then ON) or send a reset command locally via the service port with CV/CPA/Service Box2.
What to do if VAT Control Unit display shows «E 22»?
If the display shows «E 22» on your VAT Control Unit, indicating a fatal error with the rotation angle of the valve plate during operation, consider these solutions: * The valve unit may be heavily contaminated, so clean it according to the « Maintenance procedure ». * The valve plate might be mechanically obstructed; resolve the obstruction.
Why PRESSURE CONTROL does not work on VAT Control Unit?
To resolve the issue of PRESSURE CONTROL not working on your VAT Control Unit, ensure that power is supplied to the motor. Select PRESSURE CONTROL mode and perform LEARN. The problem may be due to safety mode being active, PRESSURE CONTROL not being selected, or LEARN not being completed.
How to fix «E 20» error on VAT 612 Control Unit?
To address the 'E 20' error on your VAT Control Unit, where the limit stop of the valve unit is not detected, tighten the clamp coupling screw. Then, reset or restart the valve. The error is caused by a clamp coupling screw that is not fastened.
What to do if VAT Control Unit display shows «SR»?
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.
