Supor cfxb50fc29 smart wiring controls are shown below. Cfxb40fc29. Cfxb30fc29 has the same controlled circuits as the figure below。
Example 1: on-board, with a sound of “show” inside, display screens and signlights being activated and extinguished. Power lights flash。
Analytical overhaul: measurement of 5v power supply in the con201 plugin. If normal, the problem arises on the control panel (also called light or keyboard); if abnormal, the power panel is checked. There are six plugs in con201 for gnd (geographic), +5v (electricity), rly (power plate relay control signal), x (empty foot) top (upper sensor signal input) and bot (lower sensor signal input)。
When the control panel is tested, the water stain is first tested. If so, dry or sunbath in the sun. The key is then checked for failure or short circuits. It is worth mentioning that the high temperature of iron branded may cause a failure of the key, and therefore it is recommended that the key failure be judged using substitution. Following a check, the buttons were abnormal and all new post-facilities were removed。
Example 2: get on the switchboard and hear the sound of a “push”. Some keys are out of control。
Analytic overhaul: when normal, the machine is electrically activated and the screen and the light is activated. The light came up, and the signal light led210 was found to be a little blinking at the core of the light. Dismantling led210 detects that its lamp core has been darkened and that its feet have been severely rusted; the test found a serious reverse leak. Led210 is replaced and failure is eliminated。
Example 3: key failure。
Analytical overhaul: no anomalies were detected by the method shown in example 1. Electrocharge, measuring the cross-fistation of xtal201 torque voltage, 2. 46 v and 2. 28 v, respectively, normal. Next check screen. Show screens one by one, and try one by foot. When the key is returned to normal when a foot is broken, it indicates that the problem arises on the display screen, which can be eliminated by replacing it with a new fault。
Hint: the key is restored when a foot is disconnected from the display screen, but the screen may lack a pen or, if the user accepts, the display screen。
Example 4: the default code "e0" or "e1" appears on the back screen。
Analytic overhaul: the malfunction code "e0" refers to the failure of the upper sensor and "e1" to the failure of the lower sensor. Post-sensor failure continues. The subsequent detection of top exterior components r202, c206, r204 and bot external components r201, c205 and r203 in cn201 are normal. U201 is suspected to be damaged and, in the event of new malfunctions, eliminated。
Example 5: the screens and indicator lamps are not on and there is no “show”。
Analytic overhaul: the 5v voltage of the output of the power panel is normal after the power is installed. The capacitating c201 end voltage is also 5v, which indicates that the control panel is functioning. The subsequent detection of both sides of xtal201 was 2. 57 v. Normal voltage is 2. 4 and 2. 2v, respectively. After welding u201 test, the failure remains. The xtal201 surface was found to be covered with a layer of glue that is “tight”. Is it possible that the glue was leaking? Clear the glucose test machine, troubleshooting。
Note: the plant has applied a glue on the crystal oscillation surface to protect the crystal oscillation. The adhesive effect of this glue has resulted in a failure of electricity between crystallized feet, thus preventing u201 from entering normal working conditions, which is more common。
