E.8.0 Diodes E.8.3 Testing a diode A diode must be uninstalled before it can be tested. In order to test a diode, the measuring instrument must be set to conducting direction test. Then press the yellow button. An acoustic signal sounds in the conducting direction. Conducting direction Anode Cathode Reverse direction Cathode Anode Press yellow button Set conducting direction test A faulty diode would conduct in both directions!!!
E.9.0 Fuses What is a fuse The weakest component in an electric circuit is always the first to be destroyed. The circuit is then broken. This component is usually the fuse. The task of a fuse is to protect electric devices and circuits. A fuse never serves to protect humans under ANY CIRCUMSTANCES. A fuse only protects against an overload (i.e. too much current flowing through the circuit) or a short circuit (low-ohm connection of two potentials). A fuse always has a nominal current. If this nominal current is exceeded, the fuse blows. What does a fuse consist of Glass fuse Automatic circuit breaker A fuse essentially consists of a stable housing and a wire that melts in the event of an overload or a short circuit. The fuse thus ensures that the circuit is broken safely. A fuse must never be repaired or bridged!!!!! There are slow blow fuses (T) and fast blow fuses (F). Slow blow fuses blow later than fast blow fuses. The housing usually indicates whether the fuse is a slow blow fuse or a fast blow fuse. We distinguish between 5 categories: Super fast (FF), fast (F), medium fast (M), slow (T), super slow (TT) Car fuse Fuses used at VÖGELE: Low-voltage high-power fuses (heater – 230 V AC) Car fuses (switch box – 24 V DC) Glass fuses (heater control) Low-voltage high-power fuse
