DC Functional Analysis and Circuit Checks
E3.eCheck is an extension to E3.series that enables users to functionally analyze their electrical schematic circuits and check designs for fuse and wire sizing errors. The utility works in real-time and provides instant feedback on the operability of the circuit design.
E3.eCheck is ideally suited to those working with DC control systems, such as transportation companies. Industries already served by E3.series include automotive, aerospace, railway, off-highway and special purpose vehicles.
“In the past, we’ve had to rely heavily on checking each other’s work – a laborious process with printouts and highlighter pens. By simulating the design using E3.eCheck we’re spared all of that. Also, the BOM is always reflecting the current design.”
– Carl Worthington, Principal Electrical Engineer, Mecalac (formerly Terex GB)
Functionally Intelligent Objects
In order to facilitate the functional checks special objects exist in the E3.series library, including power sources, fuses, switches, complex devices and loads. Power supplies allow the user to stimulate the circuit while fuses monitor the inline current. Switches can be activated allowing current to pass between their contacts, and complex devices such as relays are configured to open or close auxiliary contacts based on the coil operation.
During the analysis and design phase the current value and direction is constantly monitored at pin level. Voltage drop is monitored at each pin to determine the effectivity of the circuit. Inline fuses will fail should their tolerance be exceeded. Additionally, wires will fail if the current exceeds specified safety levels. This allows users to correct designs during the prototype or development phase – long before products enter the manufacturing stage.
Switches and contacts within the design are controlled by the voltage and current passing through the circuit. Energizing a coil will open and close auxiliary contacts, which in turn enables or disables current flow in other sections of the design simulating the real-life operation of the circuit. As current passes through to the load, objects such as lamps or motors voltage are checked and success or failure information is fed back to the user.
Design for Manufacture
E3.eCheck complements the comprehensive capabilities of E3.series. With its electrically-aware component library, specifically-designed kernel and numerous design rule checks, it is optimized for electrical design. Connector mates, connector pin terminals and cavity seals are automatically assigned and short-circuits and incorrect part usage is prevented, ensuring that correct design data is always available for manufacturing.
Mecalac (Formerly Terex GB) Cuts the Time Taken to Develop Right-First-Time Cable Harnesses for Its Heavy Plant Vehicles
Mecalac Construction Equipment UK is a global manufacturer of compact plant machinery, providing market-leading solutions that maximize return on investment.
We will demonstrate workflows that help designers take the next leap in productivity in various industries like aerospace, harness manufacturing, industrial machinery etc. The attendees will have a chance to ask questions and learn about the latest developments towards fully automating your design workflow.
Please join us for this interactive technical webinar where tolerance failures and detection will be discussed and demonstrated. Insure that the maximum permissible current is not exceeded by the connected load. Verify the maximum voltage for correct operation is not exceeded. What happens when a switch is operated or when a relay is activated?
