Cause analysis and solution of common failures of DC screen monitoring module
Date of publication: 2017-11-10
There are four common faults of the DC screen monitoring module: the parameters of the DC screen monitoring module cannot be set, the buzzer does not sound when the DC screen monitoring module fails, the DC screen monitoring module does not control to enter the equalizing state, and the DC screen monitoring module displays the battery capacity error.The following describes the processing methods for these four failures: 1. The parameters of the DC screen monitoring module cannot be set: the monitoring module and the lower-level equipment are not communicating, which will cause the parameters to be unable to be set; the wrong configuration will cause the monitoring module parameters to be unable to be set; the parameters exceed the limit Unable to set parameters.2. DC screen monitoring module fault buzzer does not sound: the buzzer fault monitoring module is set to silence the buzzer, which will cause the buzzer to not sound (but the fault light is on).Third, the DC screen monitoring module does not control to enter the equalizing state: important faults such as module communication interruption, AC power failure, and battery branch circuit break will cause the monitoring module to enter the fault protection state, and the equalizing charge will not be transferred; the battery current detection error will cause the monitoring module Can’t enter equalization state; manual mode will not automatically enter equalization, need to manually set to enter equalization.Fourth, the DC screen monitoring module displays the battery capacity error: the battery current detection error; needs to be set to allow equal charging to ensure battery capacity correction.DC screen
