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 neles ND7000H 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.
