If the CLOSE VALVE function isn't working, it might be because safety mode is active or maintenance mode is active. To solve this: - Provide power to the motor to allow for operation. - Refer to “Display shows «M C»” in this table.
What causes VAT 61228-KAGG-0002 OPEN VALVE not to work?
If the OPEN VALVE function isn't working, it might be because safety mode is active or maintenance mode is active. To solve this: - Provide power to the motor to allow for operation. - Refer to “Display shows «M100»” in this table.
How to troubleshoot VAT Control Unit ZERO when it does not work?
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 61228-KAGG-0002 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 61228-KAGG-0002 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.
Why is VAT 61228-KAGG-0002 PRESSURE CONTROL not optimal?
If the VAT Control Unit's PRESSURE CONTROL isn't working as expected, ensure the setup was completed fully, including performing LEARN and ZERO procedures in the correct order. Stable gas flow is crucial during the LEARN process. Tune the valve for your specific application and verify the sensor range is appropriate, ideally with the controlled pressure between 3% and 98% of the sensor's full scale. Also, use a shielded sensor cable to minimize signal noise.
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 Control Unit?
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 Control Unit?
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.
