Why are my Burkert Controller process valves not working correctly?
The process valves might not be functioning correctly due to: * No electrical power supply or communication for the control head. Check the power supply and the communication settings. * No or insufficient pneumatic supply of the control head. Check the pressure supply and ensure that the supply is sufficient.
What to do if there is no feedback signal on my Burkert 8681 Controller?
If there's no feedback signal, it could be due to several reasons. Check the target for correct mounting and condition. The position of the position measuring system might not be appropriate for the spindle position, so you should perform or repeat the Teach-In process. Ensure that the external initiator is set according to its operating instructions. Also, check the connections according to the pin and plug configurations described in these operating instructions.
What to do if the valve output 2/A1 of my Burkert Controller cannot be switched off with the control?
If valve output 2/A1 cannot be switched off with the control, the magnetic manual control may still be activated. Deactivate the manual control.
