  If the display interface of your CHINT Switch controller is not on after powering up, there might be a few reasons. First, ensure that the incoming line terminal is firmly connected and in good contact. For a 3P product, check that the product is connected to the neutral phase. Also, the controller fuse might be blown, so replace it. Finally, check if the main circuit voltage is normal, as phase loss or failure could be the cause.

Why is the displayed voltage above 300V on my CHINT NXZM?

  If the displayed voltage of phases A, B, and C on your CHINT Switch is above 300V, it might be because one circuit of the power supply of the product is not connected to the neutral pole or is connected to the live wire by mistake. To resolve this, conduct wiring correctly according to the Instructions (main circuit). Note that wrong connection will burn down the controller.

How to troubleshoot controller display failure on CHINT NXZM?

  If the controller display of your CHINT Switch fails, and shows E-1 or E-2, press the Inquiry button. E-1 corresponds to a circuit breaker trip on the normal power supply side, and E-2 corresponds to a circuit breaker trip on the alternative power supply side. If it shows E-3, switch the product to manual mode and press the Normal or Alternative button to confirm whether the product can be converted. If not, repair or replace the product, as E-3 corresponds to motor failure or motor line disconnection.

  If your CHINT Switch still shows fire control linkage after the fire control linkage signals are removed from the 501 and 502 terminals of the controller, switch the product to manual mode and press the Confirm/Return button after the signals are removed.
