Why is my Metso Control Unit test failing?
If the test failed on your Metso Control Unit, it could be due to signal wires being incorrectly connected, resulting in no value on the display, or the circuit boards might be defective. In either case, repeat the test to see if the issue persists.
Why is my Metso Control Unit overshooting or positioning too slow?
If your Metso Control Unit is overshooting or positioning too slowly, consider these potential causes: changing the PERF value may help. Also, check for leakages in tubes between the controller and actuator, as well as leakages in mechanical stop screws. Other potential issues include a dirty spool valve, a supply air tube that's too small, a dirty supply air filter, or a valve that sticks.
Why is the positioning of my Metso Control Unit inaccurate?
Inaccurate positioning of your Metso Control Unit can stem from several factors. These include a dirty spool valve, too high actuator load, supply pressure that's too low, defective spool or pressure sensors, or actuator leakage.
Why is my Metso Controller overshooting or positioning too slowly?
Overshooting or slow positioning in your Metso Controller can occur due to several reasons. You may need to change the PERF value. Other potential causes include a dirty spool valve, supply air tube being too small, a dirty supply air filter, or the valve sticking. Also, check for leakages in tubes between the controller and actuator, and inspect mechanical stop screws for leakages.
What to do if the Metso Controller valve position setpoint doesn't affect the actuator position?
If changing the valve position setpoint doesn't affect the actuator position on your Metso Controller, the spool valve might be sticking. Also, check for incorrect configuration parameters. The actuator or valve could also be jammed.
Why is my Metso Controller showing 'Inaccurate positioning'?
Inaccurate positioning with your Metso Controller could be caused by a dirty spool valve or too high of an actuator load. Also, check if the supply pressure is too low, or if the spool or pressure sensors are defective. Actuator leakage could also be the reason.
What to do if Metso Controller shows 'Error during valve travel calibration'?
If you're getting an error during valve travel calibration on your Metso Controller, ensure the valve controller is not in MAN mode. Check the coupling alignment with the pointer and verify that the parameter settings PFA and ROT are correctly selected. The actuator or valve might be stuck during calibration, the supply pressure could be too low, or the spool valve could be dirty.
What to do if Metso Controller shows 'TEST FAILED'?
If your Metso Controller displays 'TEST FAILED', try repeating the test sequence. Check if the signal wires are incorrectly connected, ensuring there's a value on the option. Also, verify that the device is not in manual or fail-safe mode.
