To Next PageTo Next PageWhy does remote operation not work on my VAT 651 Control Systems?
If the remote operation of your VAT Control System is not working, first ensure that local operation via the service port is not active and that the safety mode is not engaged (check for 'D' on the display). If so, switch to remote operation. Also, ensure that the motor is receiving power. Consult the 'Electrical connection' section for detailed instructions.
What to do if VAT Control Systems display shows «D C» or «D999»?
If your VAT Control System displays 'D C' or 'D999', it indicates that the motor interlock is open. To resolve this, ensure that the motor is receiving power to allow operation. Refer to the 'Electrical connection' section for detailed instructions.
What does «SR» mean on the display of VAT 651 and how to fix it?
If the display of your VAT Control System shows 'SR' (Service Request), it could be due to heavy contamination of the valve unit or a gate seal that is heavily sticking. To address this, clean the valve and/or replace the gate seal, following the procedures outlined in the 'Maintenance procedures' section.
What to do if VAT 651 Control Systems display shows «E 22»?
If your VAT Control System displays 'E 22', it indicates that the rotation angle of the valve plate is limited during operation. This is likely due to a mechanical obstruction of the valve plate. Identify and remove the obstruction to resolve the issue.
How to fix VAT 651 when CLOSE VALVE does not work?
If your VAT Control System is not closing, and the safety mode is active (indicated by 'D' on the display) or maintenance mode is active, ensure that the motor is receiving power to allow operation. Also, refer to the 'Electrical connection' section for details and check “Display shows «M C»” in this table.
How to troubleshoot VAT 651 when OPEN VALVE does not work?
If your VAT Control System is not opening, and the safety mode is active (indicated by 'D' on the display) or maintenance mode is active, ensure that the motor is receiving power to allow operation. Also, refer to the 'Electrical connection' section for details and check “Display shows «M100»” in this table.
What to do if POSITION CONTROL does not work on VAT 651 Control Systems?
If the position control is not working on your VAT Control System, and the safety mode is active (indicated by 'D' on the display), ensure that the motor is receiving power to allow operation. Additionally, if 'POSITION CONTROL' is selected, indicated by 'V' on the display, select the 'POSITION CONTROL' mode. Refer to the 'Position control' section for detailed instructions.
What does «E 40» mean on VAT Control Systems display?
If your VAT Control System displays 'E 40', it indicates a fatal error related to motor driver failure. To resolve this, replace the control unit following the procedures outlined in the 'Maintenance procedures' section.
Why is there a COMPRESSED AIR FAILURE in my VAT 651?
If you are experiencing a compressed air failure with your VAT Control System, it is likely due to insufficient air pressure at the air input of the valve. Connect an air supply or increase the air pressure, ensuring it exceeds 4 bar (55 psi).
Why is the pressure reading wrong or negative on my VAT 651 Control Systems?
If the pressure reading on your VAT Control System is incorrect or negative, verify the following: Ensure the sensor(s) are properly connected, confirm if a 2-sensor version is present at the valve controller by checking the valve version, and verify the configuration. Perform 'ZERO' after base pressure is reached. Also, check that the sensor power supply provides adequate power. Refer to 'Electrical connection', 'Setup procedure', and 'ZERO' sections for detailed instructions.
