Select POSITION CONTROL mode. Refer to «Position control» for details.
What to do if the VAT Control Unit display shows «E 40» (fatal error - motor driver failure detected)?
If the VAT Control Unit display shows «E 40», it indicates a fatal error due to a motor driver failure. Replace the control and actuating unit according to «Maintenance procedure».
What does 'M100' on the VAT 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 does the VAT 612 Control Unit display «D 0» Motor Interlock is open?
The VAT Control Unit displays «D 0» because motor power may not be supplied. To resolve this, provide power to the motor to allow for operation, referring to the «Electrical connection» details.
What to do if the VAT 612 remote operation does not work?
If remote operation of the VAT Control Unit does not work, it might be because local operation via the service port is active, or safety mode is active (check for D on the display). To solve this, switch to remote operation and provide power to the motor. Refer to «Electrical connection» for details.
What to do if the VAT 612 display shows «SR» (Service Request)?
If the VAT Control Unit display shows «SR» (Service Request), it could be due to a heavily contaminated valve unit. Clean the valve unit according to «Maintenance procedures» to resolve this.
What to do if the VAT 612 display shows «E 22» (fatal error - rotation angle of valve plate limited during operation)?
If the VAT Control Unit display shows «E 22», it indicates that the rotation angle of the valve plate is limited during operation. This could be due to a heavily contaminated valve unit or a mechanically obstructed valve plate. Clean the valve unit and resolve any obstruction.
What to do if the VAT 612 Control Unit CLOSE VALVE does not work?
If the VAT Control Unit CLOSE VALVE function does not work, it could be because the safety mode is active (check for D on the display) or maintenance mode is active. Provide power to the motor to allow for operation; refer to «Electrical connection» for details. Also, refer to “Display shows «M C»”.
What to do if the VAT 612 OPEN VALVE does not work?
If the VAT Control Unit OPEN VALVE function does not work, it could be because the safety mode is active (check for D on the display) or maintenance mode is active. Provide power to the motor to allow for operation; refer to «Electrical connection» for details. Also, refer to “Display shows «M100»”.
What to do if the VAT Control Unit display shows «E 21» (fatal error - rotation angle of valve plate limited during power up)?
If the VAT Control Unit display shows «E 21», it means the rotation angle of the valve plate is limited during power up. This may be due to a valve plate that is not centric adjusted, a heavily contaminated valve unit, or a mechanically obstructed valve plate. Adjust the valve plate, clean the valve unit, and resolve any obstruction.
