If your VAT Control Unit displays «E 40», it indicates a fatal error: a motor driver failure has been detected. Replace the control and actuating unit.
Why is the VAT Control Unit pressure reading wrong or negative?
A wrong or negative pressure reading may occur if the sensor(s) are not connected, a 2 sensor version is present at the valve controller, ZERO hasn't been done, or the sensor power supply doesn't provide enough power for the sensor(s). Ensure the sensor(s) are properly connected, verify the valve version and configuration, perform ZERO when base pressure is reached, and verify the sensor supply voltage.
What to do if VAT Control Unit PRESSURE CONTROL does not work?
If the PRESSURE CONTROL does not work, it might be because the safety mode is active, PRESSURE CONTROL is not selected, or LEARN hasn't been done. Provide power to the motor, select PRESSURE CONTROL mode, and perform LEARN.
Why VAT Control Unit remote operation does not work?
If remote operation doesn't work, it could be because local operation via the service port is active or safety mode is active. Try switching to remote operation and provide power to the motor.
What to do if VAT 615 OPEN VALVE does not work?
If OPEN VALVE does not work, it might be because safety mode is active or maintenance mode is active. Provide power to the motor.
What does it mean when my VAT 615 Control Unit display shows «E 20» (fatal error - limit stop of valve unit not detected)?
If your VAT Control Unit displays «E 20», it indicates a fatal error because the limit stop of the valve unit was not detected. This can occur if the clamp coupling screw is not fastened. Tighten the screw to resolve this issue.
How to fix VAT 615 when remote operation (DeviceNet®) does not work?
If remote operation isn't working on your VAT Control Unit, it might be because local operation via the service port is active, indicated by a 'D' on the display. Switch to remote operation and ensure power is supplied to the motor to allow for operation.
What does it mean when my VAT 615 Control Unit display shows «E 22» (fatal error - rotation angle of valve plate limited during operation)?
If your VAT Control Unit displays «E 22», it means there's a fatal error because the rotation angle of the valve plate is limited during operation. This is possibly due to a heavily contaminated valve unit or a mechanical obstruction of the valve plate. Clean the valve unit and resolve any obstructions to fix this.
What does «D 0» mean on VAT Control Unit display?
«D 0» on the display means the Motor Interlock is open. This is caused by motor power not being supplied. Provide power to the motor.
What does error «E 21» on VAT Control Unit mean?
Error «E 21» indicates that the rotation angle of the valve plate is limited during power up. This could be due to a valve plate centric adjustment issue, a heavily contaminated valve unit, or a mechanically obstructed valve plate. Adjust the valve plate, clean the valve unit, resolve any obstruction, and reset the control unit.
