Delivering Performance Soft start / Soft stop - the best protection against motor and equipment wear. Direct start or star delta start are today s most common motor starters. Despite technical improvements on motors as well as contactors, jerky starting and stopping could not be eliminated. Damage to motor bearings and gearboxes, premature wear, frequent faults on conveyor belts and goods which fall over when starting transport mechanisims are some of the consequences. Motor Controllers...... the Easy Way! 1 Install... Snap on DIN Rail and Connect Protect Your Equipment with... - Lower inrush current during starting - Reduced vibration during starting and stopping 2 Adjust... 3... and Start The range of motor controllers from Carlo Gavazzi comprises a large number of high performance motor controllers which enable the user to fulfill many application requirements. Our products have earned the independent approval of all relevant bodies which govern our own industry and the many industries we serve.
Motor Controllers Typical Market Applications Conveyor Belts Conveyors are an essential component for the handling of materials in a typical production process. A Carlo Gavazzi Soft Start Motor Controller applies a gradually increasing voltage to the conveyor motor, eliminating starting shock and guaranteeing that the product moves without losing balance, getting misaligned or even falling over. HVAC Ambient temperatures in different environments are kept uniform and cool by means of centrifugal or propeller ventilators. The control is generally enclosed inside small cabinets and exposed to hot ambient temperatures. For office/household units safety is an issue and a Motor Controller with thermal protection and high operating ambient temperature is the solution. Compressors Reciprocating compressors are used for high pressure cleaning of tanks, vessels, sewer lines, boilers and tubes, steel mill de-scaling and also paint removal. Motor Controllers will prevent pressure surges and extend the lifetime of piping systems, valves and couplings. Pumps Pumps are used in an extremely wide variety of applications. Direct-on-line starting can cause interference to equipment such as computers and lighting, located in close proximity to the pumps. A Carlo Gavazzi Soft Start Motor Controller can increase pump speed more gently, hence reducing inrush current. When a pump is stopped suddenly, the pressure surges and results in fluid hammer. The Soft Starter eliminates this vibration within the hydraulic system and reduces down-time and maintenance costs.
Application Durability Simplified Set-up Space Optimization Diagnostic Warning Motor Control... Soft starting and soft stopping is achieved by controlling the motor voltage. During running operation the semiconductors are bypassed by internal electromechanical relays*. Easy to Use Easy to install, adjust and start up. Simple mounting: snap on DIN-rail or attach direct to the chassis. No complex programming or memorizing of parameters. * except 3-phase controlled devices Higher Number of Starts per Hour The high number of starts per hour will reach more applications where a lot is expected by the soft starter, as in the case of wood cutting machines, high speed doors and cranes. Technological... RSH MIDI in its basic format is designed using up-to-date technology. Status Monitoring An LED array indicates the various conditions of operation. Status indication includes Power ON, Ramping, Bypass Activation, Device Over-temperature, Motor PTC Over-temperature, Phase Loss and Sequence Alarms. Going Global! The same soft starter can be used on most types of mains supply voltages around the world making it a more global solution.
RSHR MIDI Series The RSHR MIDI is the only 45mm soft starter in the market with a special combination of builtin bypass contactor and external heatsink for optimal performance. The RSHR MIDI meets the needs of more demanding applications by improving number of starts per hour through higher thermal efficiency and a superior overload current profile. The RSHR MIDI provides improved starting conditions over conventional star-delta starters. This Soft Starter is ideal for standard applications such as centrifugal pumps, fans, dryers, mixers, conveyors, granulators etc. RSHR 3-Phase Series This 90mm wide format also houses devices with switching of all three phases, also known as 3-phase controlled. These products are ideal for heavy applications such as circular saws, band saws, mills, grinding machines etc. Three types of Soft Starters are available in this series: 1. In-line, 3 wire connection of the motor load RSHR..V32 RSHR..V34* 2. Inside-delta, 6 wire connection of the motor load: RSHR..V33 RSHR..V35* 3. In-line, 3 wire connection, special version for compressors: RSHR..Sxx (consult your Carlo Gavazzi sales office) *needs external power supply
Application Durability Simplified Set-up Space Optimization Diagnostic Warning Features and Benefits The RSHP Flexy is a microprocessor-based softstarter for 3-phase induction motors in a compact new format. While offering versatile ramping features, the RSHP Flexy is also very easy to configure. It is possible to match the start/stop ramping profiles with the functional requirements of specific motor loads. A clever push-button and LED user interface eliminates the added cost of an alphanumeric display. The RSHP Flexy uses an in-house designed system that ensures efficient power management. Typical Ramp Profiles The RSHR is a compact easy-to-use AC semiconductor motor controller. With this controller 3-phase motors with nominal load currents up to 45 A can be soft started and/or soft stopped. Starting and stopping time as well as initial torque can be independently adjusted by builtin potentiometers.
Motor Controllers Optimized Performance High number of starts per hour due to optimised combination between thyristor technology and external heatsink The RSHR and RSHP Flexy have a wide operating temperature range, which allows their use in more extreme applications. Up to 45A AC53b current at an ambient temperature of 40 C (104 F). Monitoring of soft starting operation to eliminate unwanted vibrations. Indications and Alarms The status indication for Power, Ramp, By-pass operation and SoftStarter Overheating facilitates observation and diagnosis of the current operation of the softstarter. Versatile self-diagnosis: Motor PTC protection alarm, internal over-temperature protection, phase loss and sequence alarms on power up. The RSHR and RSHP switch off motor in the event of overheated motor windings. Compact Design SPACE SAVER! Compact starter solution for induction motors up to 22kW (400V) No large heatsink is required and it is also possible to mount the soft starters side by side, therefore saving space in the panel. User-friendly push-button interface that allows easy customisation of ramping parameters to match specific motor load
