The control panel of the electric skylight is easily operated by the driver and is usually installed in the roof of the cockpit. While different electric skylights may have different control functions, in general they include basic operations such as slide open (sliding), close (closing) and tilat up (slashing upwards). Knowledge of these operations is essential for normal use and extended life。
And then we went into the structure and principles of the electric skylight. The electric skylight consists of complex components such as power drives, transmission units and control systems. The work of these components is carried out primarily through the power-driven transmission apparatus to achieve precision control of the skylight. Understanding these structures is essential for mapping and troubleshooting, as it can help us identify the root causes of the problem and take effective remedial measures。
Skylight control mode and automatic return
The skylight control switch provides both automatic and manual modes. The two models are distinguished by the duration of the operation switch. In automatic mode, if the switch is pressed for more than 0. 4 seconds, the skylight power will continue to perform the corresponding switch. On the other hand, in manual mode, if the switch is released within 0. 4 seconds, the skylight generator immediately stops work. Switches have a reaction time of approximately 40 ± 10 ms. In addition, there is an automatic return mechanism for skylights to ensure safety, especially when the body or other alien is caught。
The skylights run and overheat protection
In order to prevent overheating and even burning of electrical units due to prolonged operation, many vehicles have solar and door and window generators equipped with overheating protection. The continuous working time of the electric power is set at 120 ± 10 seconds. The electric power can continue to work during this period and then enters a heat-dissemination period of 8 ±2 seconds. In the course of repeated work, the electric power automatically ceases to disperse after 9 seconds of work。
In some cases, the electrical skylight system needs to be initialized, for example, when the system is first installed, replaced or repaired. Initialization steps include holding a specified switch for more than one second, performing mandatory tilt-up operations and continuing to hold the switch during the process to ensure completion of the step。
Fault clearance points and leak solutions
Mechanical failures such as leaks are more common in the use of skylights. The first task is to check whether the skylight drains and slides are blocked by miscellaneous items. The skylight was designed to take into account waterproof requirements, with a conductor tank around it and a drain pipe hidden in column a. Learn emergency shut-down methods, for example, volkswagen branded vehicles are equipped with a six-angle vigil that can be used for manual forced shut-down. If the skylight movement is slow or unable to move in a certain direction, it can also first be checked and broken at the mechanical level。
