If ZERO isn't working, it could be because the valve is not in the open position or ZERO is disabled. To fix this: - Open the valve and bring the chamber to base pressure before performing ZERO. - Enable ZERO.
What to do if VAT Control Unit pressure reading is wrong or negative?
If the pressure reading is incorrect or negative, it could be due to the sensors not being connected, a 2 sensor version present at valve controller, ZERO not being performed, or the sensor power supply not providing enough power for the sensors. To fix this: - Refer to «Electrical connection». - Check the valve version and verify the configuration. - Perform ZERO when base pressure is reached. - Verify the sensor supply voltage.
How to fix no dots lighted on VAT Control Unit display?
To resolve the issue of no dots being lighted on the display of your VAT Control Unit, connect the valve to the power supply according to the electrical connection guidelines and ensure that the power supply is working.
How to fix «E 40» error on VAT 612?
To resolve the 'E 40' error on your VAT Control Unit, indicating a motor driver failure, replace the control and actuating unit.
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.
Why ZERO does not work on VAT 612?
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.
Why pressure reading is wrong on VAT 612?
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 remote operation does not work on VAT Control Unit?
To troubleshoot remote operation issues with your VAT Control Unit, first, switch to remote operation. Then, ensure that power is supplied to the motor. The cause may be local operation via service port being active or safety mode being active.
Why OPEN VALVE does not work on VAT Control Unit?
If the VAT valve does not open, ensure that power is supplied to the motor. Refer to «Electrical connection» for details. Also, refer to “Display shows «M100»”. This issue may occur if safety mode or maintenance mode is active.
Why CLOSE VALVE does not work on VAT 612 Control Unit?
If the VAT valve does not close, ensure that power is supplied to the motor. Also, refer to “Display shows «M C»”. This issue may occur if safety mode or maintenance mode is active.
