An aquastat is a device used in hydronic heating systems for controlling water temperature. [1] [2] To prevent the boiler from firing too frequently, aquastats have a high limit temperature and a low limit.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
The hard-wired nature of these components made it difficult for design engineers to alter the automation process. Changes would require rewiring and careful updating of the documentation. Troubleshooting was a tedious process. [4] When general-purpose computers became available, they were soon applied to control logic in industrial processes.
As electronic digital logic has become more accepted in industrial control, the role of fluidics in industrial control has declined. In the consumer market, fluidically controlled products are increasing in both popularity and presence, installed in items ranging from toy spray guns through shower heads and hot tub jets; all provide oscillating ...
Control logic is a key part of a software program that controls the operations of the program. The control logic responds to commands from the user, and it also acts on its own to perform automated tasks that have been structured into the program. [1] Control logic can be modeled using a state diagram, [2] which is a form of hierarchical state ...
In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and the resulting slow turn-off behavior.
