Other detection circuits of Santana 20OOGLi

Published:2011/5/15 0:40:00 Author:Borg | Keyword: detection circuits, Santana

With V.A.G151 fault diagnosis equipment, we can not only find out the fault position,but also detect the working parameters of relevant parts, which can provide dependable back-up for exactly judging faults. Apart from the above detectors, there are also throttle sensors. Furthermore, the coolant temperature sensors, admission temperature and computer power voltage can be detected with V.A.G diagnosis meter. The measuring methods are almost the same, just remember the address code of 01, and input the relevant function codes, then detection is to start.   (View)

Frost Alarm (2)

Published:2011/5/14 4:13:00 Author:Sue | Keyword: Frost, Alarm

Working Principle: As seen in the figure 4-110, the frost alarm circuit consists of power circuit, temperature detection controlled circuit and alarm circuit. When S is connected, the alarm circuit prepares to work. When the temperature is higher than 1℃, Q is disconnected and the alarm circuit doesn't work, and BL makes no sound. When the temperature is lower than1℃, Q is connected and IC begins to work. IC's 3 pin will output audio electric signal, which will promote BL to make a warning sound after the signal is amplified by V.   (View)

Inverse proportion basic circuit diagram

Published:2011/5/13 3:54:00 Author:Ecco | Keyword: Inverse proportion, basic circuit

1. The basic circuit: Voltage series negative feedbackThe input end is virtual short, virtual-off The features: Reverse side is the virtual ground, so the common mode input can be regarded as 0, the CMRR on the op amp requires low. The output resistance is small with a strong load capacity When it requires a large magnification, the feedback resistor is high, the stability is poor. If the required magnification is 100, R1 = 100K, Rf = 10M.   (View)
