In this functional model of an original electromechanical power steering the componentsare exposed within the steering housing in order to demonstrate for example the operation of the double drive pinion. The system has a controlpanel with emergency stop switch, ignition switch, indicator light and OBDinterface. The power supply is provided by a vehicle battery. Optional errorcircuit 6 switches / 12 errors and associated test sockets in 4mm design. Because of the extremely high forces onall moving parts and rotating the open areas were fitted with transparentcovers for safety. More represent able functions are active reset in thedirectional stability as well as the controlled demand for power consumptionfor reduction in fuel consumption. Steering angle, powerconsumption and torque can be tested and measured using standard workshop diagnostic systems via the OBD interface. The communication between the controlunit for steering column electronics, the diagnostic interface (gateway) andthe Diagnostic Interface (OBD) is done via CAN Bus. Thus, the required effort withand without assistance can be represented visually. In order to increase the steering forcespartially, a resistance pressure box is mounted.

Electrical counters are used in a wide variety of applications including production counting, reject counting, sorting, and flow timing. The Electronic Counter Learning System features a digital 3-digit electronic counter set within a heavy-duty, 11-gauge steel slide in panel built to stand up to frequent use. Electronic Counter Learning System adds to the Motor Control Learning System to teach electrical event counting in electrical motor control circuits.
Electronic Counter Learning System also features world-class curriculum that covers counter and timer operation, designing circuits, and troubleshooting. Learners can also practice troubleshooting a timed one-shot motor control circuit and a timed repeat cycle motor control circuit. Learners can then directly apply this theoretical knowledge to practice hands-on skills such as designing a timed one-shot motor control circuit, a timed repeat cycle motor control circuit, and a motor control circuit using the counter to tally operations.
Features:
Teaches electrical event counting in electrical motor control circuits
Heavy-duty components
Multimedia curriculum available
Hands-on skills.

Almost all the new generation commercial and military aircraft utilize electronic displays in the cockpit. Training imparted on an ARINC 429 based EFIS will prepare the students to easily understand other EFIS based on other versions of commercial and military avionics data busses. EFIS Trainer has been designed to enable avionics students to understand a typical digital bus EFIS system, and to perform maintenance and troubleshooting tasks that are typically encountered by avionics maintenance personnel. Electronic Flight Instrument System is the essential component of Glass Cockpit. he most widely used avionics data interface standards. It has been installed on many commercial passenger and transport aircraft including Airbus A310/A320 and A330/A340, Bell Helicopters, Boeing727, 737, 747, 757, 767. The fault panel allows for the simulation of typical aircraft EFISi nstallation faults including sensor feed faults. The faults are easy to select but not apparent to the student. A numbered switch panel or patching panel with cover is provided. The EFIS Trainer is based on Two Display Units, a Symbol Generator, a Control Unit, a Signal Simulator, and an Instructors Panel. Electronic displays are multi mode with ADI, HIS and Map modes. Map mode allows for superposition of Weather Radar data and sector display. Wiring harnesses in the trainer are representative of aircraft standards in hardware and wiring / looming techniques. Interconnect diagrams and panel circuit and layout diagrams are also provided.
