Mechanical and electrical assembly of control circuits is accomplished without the use of hand tools. The Control of Industrial Motors Training Systems are the perfect add-on to the Electromechanical Training Systems, Series 8001, for those who wish to extend the teaching of electromechanical systems to the control of industrial motors. All electromechanical control components have a patented metal extrusion which securely locks them into the desired position along a snap-track on two mounting modules. These modules, which are designed to be installed in the EMS Training System workstation, are each provided with two sections of snap-track. The student manual, included with the training system, guides students through a large variety of electromechanical control circuits, beginning with simple concepts and expanding them until the full sophistication of industrial motor control is reached. Students gain first-hand knowledge of the reasons behind certain practices, as well as how circuits operate. The manual is complete with a glossary of terms containing the current NEMA, IEC, ANSI, and IEEE official definitions of electrical terms. Note that two student teams have to collaborate and share the following models to perform the exercises; • • • Time-Delay Relay, Model 9107-1 Control Relay Module, Model 9108-1 Component Panel, Model 9127-1 Additional copies of these models are available in option.

Two mounting modules, each fitted with two sections of snap-track to hold components in place in either a vertical or horizontal plane, can easily be inserted into an Electromechanical System (EMS) workstation. All component terminals are provided with 4 mm safety banana jacks to permit quick circuit connections with stacking banana-plug leads. A set of banana-plug connection leads in three color-coded lengths is supplied with the system. Component terminals are identified by a standard numbering code, and interconnections described in the courseware refer to the code in the wiring diagram. Each component is complete with its own silk-screened schematic symbol, including numbered terminals. The lab manual guides students through control circuits, beginning with simple concepts and advancing to sophisticated industrial-motor controls, providing students with an understanding of the reasons behind certain practices, as well as how the circuit operates. Even the effects of inertia and gravity are incorporated into the scope of the program. The manual is complete with a glossary of terms containing the current NEMA, IEC, ANSI, and IEEE official definitions of electrical terms. An integral component of this system is the balanced inertia Wheel, Model 9126, that securely attaches to any EMS 0.2 kW rotating machine. When the inertia wheel is rotated at 1800 r/min, it stores 790 joules of energy (550 joules at 1500 r/min). All components of the Control of Industrial Motors Training System are stored in an inventoried roll-out drawer in a steel storage cabinet finished in black and gray baked enamel paint.

Four rubber-tire swivel casters allow easy movement of the workstation in the laboratory classroom. The lower portion of the workstation serves as a storage cabinet with two hinged panels and a lock handle. Immediately above the storage cabinet is a pullout work surface with a scuff- and burnresistant laminate finish. The upper portion of the workstation consists of three rows of compartments designed to house EMS modules. Two of these rows have full-height compartments while the other row has half-height compartments. Each row of full-height compartments can accommodate up to three full-size EMS modules or six half-size EMS modules, whereas the row of half-height compartments can accommodate up to three half-size EMS modules. Module Installation The EMS modules are guided into position along stainless steel guide rails. Separators between each bay of the workstation ensure perfect alignment of the EMS modules and allow their easy insertion in the workstation. A holding mechanism ensures that each EMS module stays in place once it is installed in a compartment of the workstation. Front-mounted push levers allow all EMS modules on a single row to be released for easy removal. © Festo Didactic 9 Control of Industrial Motors Training Systems, LabVolt Series, 8045 Safety Padlock Bars Two safety padlock bars on the front of the workstation prevent students from removing EMS modules during laboratory exercises. The bars can be removed and locked to the side of the workstation when the safety lock is not necessary. Additional Information Six holes in the rear panel of the workstation allow connection to a power supply, as well as the connection of 2 kW machines to their interconnection modules. Assembly of the workstation before painting ensures that each EMS module in the workstation is correctly grounded.

The centrifugal switch and contact points of the machine are mounted externally to allow students to examine their construction and observe their operation. The switch, the starting auxiliary winding, and the main running winding are all independently terminated and identified on the faceplate to facilitate experimentation of various machine connections, including open- and short-circuit fault conditions. The starting winding is circuit breaker protected against overloads. Because of the open bell housing construction, students can compare the relative size, position, and turns of the starting winding and the main running winding. An externally mounted starting capacitor is also independently terminated and identified on the faceplate to permit experimentation as a split-phase or a capacitor-start single-phase induction motor.

Each bank consists of three resistors connected in parallel that can be switched on or off with toggle switches to obtain various resistance values. This allows the total (equivalent) resistance of each bank to be increased or decreased by steps. Six safety banana jacks on the module front panel provide access to each resistor bank. The three resistor banks can be connected separately for operation in three-phase circuits. Also, the three resistor banks can be connected together for operation in single-phase circuits. The Resistive Load is commonly used in conjunction with other basic load modules, like the Inductive Load and the Capacitive Load to experiment with the effects of different types of load on a circuit.

It is fitted with one dc voltmeter, one dc milliammeter, and one dc ammeter. Meter ranges and scalar values of each instrument have been carefully selected for compatibility and are appropriate for the electrical values to be measured. All meter readings are direct indications and do not require the indicated value to be mentally multiplied by a constant.
