Causes of a short circuit or open circuit in the pressure transmitter

First check whether the indoor ambient temperature sensor is not connected or is there a damaged display, or whether the sensor panel is damaged or the communication fault with the motherboard is displayed, or the panel and the indoor panel communication line are not connected; there is also a connection. The line feels a short circuit or open circuit caused by the connector not being plugged in.

If the fault caused by the above reasons can directly replace the insert on the inner panel of the connecting cable, the plugging can be directly inserted. If the plug is not tight, it is very likely that the three 3-pole tubes in the communication circuit are damaged. Return to the factory for maintenance electrical schematics.

If the control panel keys are out of order and the remote control is operational, it may be because:

1, because the remote control operation can receive, so it can be ruled out that the main computer board problem;

2. The D1～D12 diode used for scanning the button on the display board uses the low frequency diode IN4007, and the main program handles the high frequency of the button; the individual control panel is incompatible with its own motherboard, and the main operation is performed during the button operation. The program does not respond correctly to the signal from the button, causing the button operation to malfunction.

The solution to the open or open circuit of the pressure transmitter is relatively simple. It is caused by just a few problems. When we know the cause of the fault, we can find a good solution to solve the open or short circuit fault of the temperature sensor. However, when you can't solve these problems, don't be reluctant. You need to contact the manufacturer to return to the factory for repair or ask the technicians of the manufacturer to check and repair to avoid more faults.

Therefore, for the convenience of users, Huaheng Instrument sincerely provides services for you.
