How to Do ISP Programming – Part 4: Fuses and Troubleshooting




Setting Fuses

As mentioned before, fuses are used to set a couple of things that might need to be set before the actual software starts to run. As a beginner you should not tinker with most of those settings, because it is possible to lock yourself out of in-system programming.

The most dangerous fuse bits in that respect are SPIEN (SPI enable) for obvious reasons and RSTDISBL (reset

Electrical Contactors AC1, AC2, AC3, AC4

Image
Electrical Contactors Utilization Categories:- Electrical Contactors are categorized according to the current making and breaking values for contactors. This will depend on the following: The type of load to be controlled (Inductive load, Lighting load, Motor load, Resistive load, Capacitive load) The operating cycle conditions. For any applications there are different contactors available depending upon load application which every electrical engineer you must know before designing any systems.  You may have often seen the ratings described on contactor name plate depicting various parameters. One of most important to be considered are as described in this article.  AC1 - These type of contactors are used for Non-inductive or slightly inductive loads they are used for Heaters which are resistive loads. AC2 - These type of contactors are used in Starting of slip-ring motors AC3 – They are particularly used for Starting of squirrel-cage motors and sw...
