M-23A, M-23B, M-3 and Low-Profile M-3 Electric Switch Machines

Switch Machines and Associated Equipment Ansaldo STS USA M-23A, M-23B, M-3 and Low-Profile M-3 Electric Switch Machines ASTS USA s style M Electric Switch Machines are rugged, reliable, units designed for any installation where electric power is available. The M-23A and M-23B units have dual control features, including a hand-throw lever to permit operation by on-site trainmen or maintainers, as well as by remote controlled power. The standard and Low-Profile M-3 Switch Machines are recommended for applications where there is seldom a need to manually operate the switch. These three machines are available with a variety of operating speeds, gear ratios and motor voltages. Numerous circuit controller configurations are also available, both mechanical and electronic.

These include various operating voltages, gear ratios, throw times and control wiring schemes as shown in the ordering tabulations. Basic differences include the following: M-23A and M-23B with: Mechanical circuit controller. Electronic Circuit Controller (ECC) and Motor Control Unit (MCU) With independent point detection Without independent point detection General Description (cont d) M-3 with: Mechanical circuit controller for general installations. ECC and Electronic Biased Neutral Controller (EBNC) With independent point detection Without independent point detection Low-Profile M-3 with: Mechanical circuit controller. Without independent point detection Refer to the ordering tabulations to determine which of the above options are available in which combinations, or are stand-alone options. Basic Design Style M Electric Switch Machines consist of a motor, a gear train, a cam arrangement (for operating the switch and locking) and a circuit controller. All of these machines use the same basic casting, and are interchangeable with respect to mounting and connections in a switch layout. However, the M-23A and M-23B machines require a somewhat higher clearance than the standard M-3 or Low Profile M-3. Both models of the M-3 Switch Machine can be operated by hand by inserting a temporary crank. For installations where extra vertical clearance is needed, the Low Profile M-3 Electric Switch Machine is recommended. This machine is similar to the standard M-3 in design and operation, but is 5/8-inch (1.58 cm) lower in vertical dimension. This small but important height reduction makes the Low Profile M-3 ideal for third-rail transit applications where additional clearance is needed for the vehicle pick-up shoe.

Ansaldo STS USA General Description (cont d) vertically lifted from the machine, allowing easy handling in tight confines. Left and right-hand versions of this machines are available, each with a single operating voltage, gear ratio and wire control scheme. The M-23A uses a different hand-throw pinion than the M- 23B, which affects hand-throw locking. Power operation is the same with both machines. In the M-23A, the hand throw lever gives the same mechanism stroke and full lock rod protection as the power operated mode. In the M-23B, however, the lever does not provide lock-rod protection (slide bar and lock box do not move full stroke). All M style machines are wired at the factory, with internal wiring connected to a main terminal board in the motor compartment. A typical wiring diagram or working drawing is enclosed with each shipped machine to show how external connections should be made to the main terminal board for a particular application. Motor and Gear Train ASTS USA M Electric Switch Machines use a fully enclosed, permanent magnet motor. This type of motor provides lower inductance, better EMI immunity and higher efficiency than previous field wound motors, and incorporates simpler 3-wire control. (Permanent magnet motors are also available for retrofitting older models of these switch machines; see RSE-6A4.) The gear train in the M style Switch Machines is comprised of a pinion on the end of the motor shaft, one or two reduction gears, clutch gear, friction clutch, worm shaft and worm gear. Three different gear ratios are used to provide three operating speeds: 189:1, 360:1 and 528:1. The Low Profile M-3 incorporates the same basic gear train concept as the other style M machines, and is provided with a single gear ratio of 189:1. In all style M machines, a friction clutch protects the mechanism from the shock incurred at the end of a stroke, or when an obstruction is present. For complete motor and gear train specifications, refer to the ordering tabulations. Mechanical Circuit Controller The mechanical Circuit Controller used in the style M switch machines has four pairs of contacts. Two motor control contacts are wired internally. The remaining are indication contacts for external switch position determination. To allow standardized wiring, provision is made to always have certain contacts set as normal, regardless of which end of the operating stroke is designated as normal. Machines equipped with an mechanical circuit controller include a point detector with latch device. A latchout kit is available for the point detector mechanism (see RSE-6A4). Components in this kit enable the circuit controller indication contacts to be held open (until reset) when the point detector bar is displaced while the machine is in locked-up condition (i.e. switch points obstruction). M-23A, M-23B, M-3 and Low-Profile ECC+EBNC or ECC+MCU ASTS USA offers models of its standard M-3, M-23A and M- 23B switch machines outfitted with an Electronic Circuit Controller (ECC), in conjunction with an Electronic Biased Neutral Controller (EBNC) or Motor Control Unit (MCU). A true linear detection device with no moving mechanical parts to maintain, the ECC eliminates circuit-controller sensitivity degradation due to component wear. The ECC utilizes inductive proximity sensors to continuously monitor switchmachine conditions. It vitally monitors the position of the switch points and the internal locking mechanism, delivering switch-machine indications to the wayside. For more information on this device, refer to RSE-6F3. ASTS USA can also add the ECC unit into existing machines returned to the factory for refurbishment; refer to the RSE catalog introduction for more information on this service, or contact your ASTS USA Account Executive. The EBNC is used in the M-3 machines with ECC to enable direct control of the switch machine using a bipolar output of a vital logic controller such as the MicroLok II or the MicroLok Object Controller. In an EBNC-equipped machine, the motor power is fed from a fixed polarity source (direction determined by the EBNC). In the M-23A and M- 23B machines with an MCU, motor power is fed from a bipolar source (direction determined by the wayside control equipment). The M-3 s EBNC includes a motor overload protection function. Overload protection for the M-23A/B s MCU is provided by the wayside control equipment. Existing installations using 3- or 5-wire control are converted to 2- wire control when installing an M-3 ECC/EBNC or M-23A/B ECC/MCU machine. Independent Point Detection (IDP) Selected models of the M-3, M-23A and M-23B switch machines (with mechanical circuit controller) are equipped to provide independent point detection. With this feature, the point detection mechanism senses the position of the near and far switch machine points independently to ensure that both are in the proper relative positions to each other and the rails. Thus, any mounting problems or unwanted slack in the connecting rod between the points are detected. (In other switch machines, only the nearest switch point movement is monitored). M-3 Machines for Replacement of Alstom Machines with 2- Wire Control Four versions of the M-3 Switch Machine with mechanical circuit controller can be used to replace selected Alstom with 2-wire control.
