If the control of your Chino Controller is unstable, check the following: 1. Ensure that the wiring is done properly. 2. Confirm that the terminal screws are tightened firmly. 3. Check for any noise influence. 4. Verify that the parameters (PID, output limiter, etc.) are set correctly.
What to do if Chino Controller behaves strangely and the cause is unknown?
If your Chino Controller is behaving strangely and the cause is unknown: * First, check that the parameters are set correctly. * If the problem persists, initialize the settings, redo all the settings, and then check if the issue is resolved.
What to do if PV display shows " " on Chino DB670?
If the PV display on your Chino Controller shows " ", this indicates an over range or upper limit burnout for the measuring range. To resolve this, check the sensor signal.
What does it mean when PV display shows " " on Chino DB670?
If the PV display on your Chino Controller shows " ", it means there is an under range issue for the measuring range. You should check the sensor signal.
How to troubleshoot errors in measured value (PV) on Chino DB670?
If you are experiencing errors or instability in the measured value (PV) on your Chino Controller, consider the following checks: * Ensure the wiring to the sensor is properly connected. * For thermocouples, verify the wiring to the terminal screw uses thermocouple or compensation lead wire. * Confirm that terminal screws are firmly tightened. * Make sure the sensor signal isn't connected in parallel with another instrument. * Check that any protection element connected to the sensor signal maintains a low resistance. * Verify there are no issues with the output signal or specifications of the sensor itself. * Look for any noise influence. * Confirm the operating environment is appropriate. * Check that parameters are set correctly. * If using a calibrator with a therm...
