Common faults of tower clock operation
Tower clock as a high frequency of use of building clocks, if the failure of the problem, is indeed a very headache, do you know about this product? Do you know of any common faults in its operation process? The following Xiaobian will simply introduce it to you.
1, its crystal oscillator and series resonant capacitor damage, after the destruction of the crystal oscillator two pin working voltage abnormal, clock chip output abnormal, there is no working voltage wave mode, resulting in a whole motherboard interface no clock, no correction. When the frequency deviation occurs, the CPU may not install the system software, cannot enter the system, blue screen of death during the running process, the CPU frequency identification is incorrect, and even the old CPU may run normally, but the new CPU does not run.
2, the probability of tower clock circuit failure on the motherboard interface is not high, and sometimes it is not the damage of electronic components. Air welding, air oxide layer is too heavy will cause abnormal clock circuit operation, welding method to solve the problem of clock circuit fault is the method we often choose, power supply system electronic components, crystal oscillator equipment failure rate is relatively high.
3. The speed of the tower clock is likely to be affected by the geographical environment where the clock is located; Pendulum control screw loose; When the needle tube and the hour hand are loosened and the needle slips; The escapement fork teeth are shallow or touch the escapement wheel teeth, when this happens, we can remove the screw cap, pad a rubber or wood board above and below, the slot is parallel to the control table, and then hammer, or clamp with pliers to make it slightly deformed. Use the pliers to bend the four spring claws downward to improve the total height, the four need to be consistent, the friction torque is 0.2-0.6N.m, and the rotation should be stable.
