    Chapter 2: Electrical Installation 2.2 – Electrical Connections – Specifications 2.2.1 – Electrical Supplies The SR44 requires two AC electrical power sources: 1) A balanced 3-phase main source to provide the power for the controlled motor. 2) A single-phase supply: 115V or 230V, 50Hz/60Hz, for the internal control circuitry. The soft starter must be connected to a 3-phase power supply and a 3-phase load for proper operation.

  • Page 46: Chapter 3: Applications

    Chapter 3: Applications 3.1 – Motor Suitability and Associated Considerations The SR44 Soft Starter is based on a series of microprocessor-based optimizing soft starters which have been used world-wide in more than 100,000 critical and non-critical systems. Since 1983, these soft starters have successfully operated with almost every type of load and environment from the Antarctic to the Jungle.

  • Page 47: Maximum Motor Cable Length

    Chapter 3: Applications 3.1.4 – Maximum Motor Cable Length The length of the cable between the output terminals of the starter and the motor should not normally be greater than 100 meters [328 ft]. 3.1.5 – Power Factor Correction Capacitors Power factor correction capacitors applied to a single motor must ALWAYS be connected by a separate contactor placed on the SUPPLY side of the SR44 Soft Starter.

  • Page 48: Efficiency

    Chapter 3: Applications 3.1.11 – Efficiency Although the use of the soft starter introduces a power loss, the system still retains an overall efficiency of approximately 99.5%. If the optimizing function is selected, then the gain in motor efficiency at partial loads is far greater than the loss of efficiency arising from thyristor heat losses. If prolonged operation at full load is expected, the thyristor loss can be eliminated (as in some matched motor/pump drives) by closing a bypass contactor around the soft starter.

  • Page 49: Rules For Specific Applications

    Chapter 3: Applications 3.2 – Rules for Specific Applications 3.2.1 – In-Delta Operation The SR44 control system allows the soft starter to be installed “in the delta” connections of the motor, which can permit the use of a lower current rated unit. However, in this mode of operation it is important that the soft starter is connected in accordance with the relevant wiring diagram.

  • Page 50: Soft Stopping

    Chapter 3: Applications 3.2.7 – Soft Stopping Soft stopping can reduce positive surge pressures in pipelines on shutdown. It is necessary to make sure that the ramp-down time is long enough to remove the energy from the fluid before the firing of the thyristors is stopped.

  • Page 52: Concepts And Principles Of Fixed-Speed Induction Motor Starting

    Chapter 3: Applications 3.3 – Concepts and Principles of Fixed-Speed Induction Motor Starting and Control Since its invention one hundred years ago, the standard three-phase induction motor has become one of the most familiar items of industrial equipment ever known. Due to its simplicity of construction, low cost, reliability, and relatively high efficiency, it is likely to remain the prime source of mechanical energy for the foreseeable future.

  • Page 54: Starting Induction Motors

    Chapter 3: Applications 3.3.2 – The Induction Motor (continued) Obviously, the larger the difference between the developed torque and the absorbed torque, the faster the acceleration and the quicker full speed is reached, and the greater the stresses experienced by the supply and drive systems during the acceleration process. An “ideal” start would accelerate the load with just sufficient force to reach full speed smoothly in a reasonable time, and with minimum stress to the supply and drive mechanisms.

  • Page 55: Electro-Mechanical Methods Of Starting

    Chapter 3: Applications 3.3.4 – Electro-Mechanical Methods Of Starting Method A: Direct-on-Line The most simple means of controlling energy flow to an induction motor is to interrupt the power supply by a single contactor. Very widely applied, the method is known variously as “direct-on- line”, “across-the-line”, “direct”, etc., and is the usual form of control where low cost is the first and most important consideration.

  • Page 56: The Semiconductor Motor Controller

    Chapter 3: Applications There are methods of control, for example, the Wauchope starter, which eliminate or reduce the reconnection transients. However, such starters are expensive and have reliability implications, and they are not widely applied for these reasons. The wye-delta starter also has disadvantages due to the restricted starting torque available (if you need 40% LRT to break-away, you can only increase the motor size, or revert to direct-on-line).

  • Page 57: Running Induction Motors

    Chapter 3: Applications 3.3.6 – Running Induction Motors Once a start has been completed, the motor operating efficiency becomes of interest. When working at or near full load, the typical three-phase induction motor is relatively efficient, and readily achieves efficiencies of 85% to 95%. However, as shown below, motor efficiency falls dramatically when the load falls to less than 50% of rated output.

  • Page 58: Reliability Considerations

    Chapter 3: Applications All SR44 Soft Starters are microprocessor controlled, and this gives them a number of advantages. Firstly, there are no adjustments to be made for the energy saving function; all calculations necessary to find the best degree of phase-back of the thyristors for any load condition is made by the microprocessor.

  • Page 59: Principles Of The Optimizing Mode

    Chapter 3: Applications 3.4 – Principles of the Optimizing Mode 3.4.1 – Principles Every wound-field electric motor must consume some minimum amount of energy to provide a magnetic field which enables it to work at all. With DC motors the field is under separate control, so that the amount of magnetizing energy can be adjusted to be sufficient to overcome losses and provide an armature reaction appropriate to the load.

  • Page 60: Advantages Of Energy Optimizing

    Chapter 3: Applications 3.4.2 – Advantages of Energy Optimizing A soft starter with an energy-optimizing feature alters the motor operation. The energy-optimizing function reduces the terminal voltage applied to the motor so that the energy needed to supply the field is more closely proportioned to the torque demand. The effect is shown in the Figure below. Figure 3.4.2.1: ‘Full Speed’...

  • Page 61: Optimizing With The Sr44 System

    Chapter 3: Applications 3.4.4 – Optimizing with the SR44 System NOTE: SR44 soft starters have been discontinued. Please consider SR55 soft starters as a replacements. During start-up, the SR44 software uses a patented method to compute and store a reference value for the power factor.

  • Page 62: How Much Energy

    Chapter 3: Applications 3.4.5 – How Much Energy? The amount of energy used by a squirrel-cage induction motor operating with a soft starter in energy-optimizing mode is shown in the following figure (Figure 3.4.5.1), for the same duty cycle as Figure 3.4.1.2. By reducing the voltage when torque demand is below maximum, the magnetizing current is proportioned to the torque current.

However, the EMC performance of the controller can be significantly affected by the manner in which it is incorporated into the system in which it is intended to operate.

  • Page 69: Emc Basic Criteria

    Chapter 4: Electromagnetic Compatibility 4.5 – EMC Basic Criteria The electromagnetic compatibility of a product is defined by two criteria: 1) Immunity to electromagnetic disturbances generated externally to the product. 2) The type and amount of conducted and radiated electromagnetic emissions emanating from the product.

    Chapter 4: Electromagnetic Compatibility 4.7 – Basic EMC Considerations 4.7.1 – Immunity The product standard for immunity requirements is EN 60947-4-2:1996. All SR44 Soft Starter products meet, or exceed the industrial level immunity requirements laid down in this standard. 4.7.2 – Emissions Emissions are classified as low frequency (below 9kHz), known as harmonics, and high or radio frequency (above 9kHz).

    Chapter 4: Electromagnetic Compatibility 4.7.5 – Emissions - Conducted Conducted emissions are able to travel great distances and may cause interference to any neighboring consumers connected to the common low-voltage supply network. Allowable levels for conducted emissions generated by semiconductor motor controllers and starters are influenced by the nature of the low-voltage power distribution network.

    Chapter 6: Serial Communications 6.5.4 – P-124 Offline Commands The SR44 has a mechanism for carrying out common functions, or offline ones which take a long time and require the SR44 to be off and disabled. Commands are carried out by writing various values to a Command Register (parameter 124).
