M-23A, M-23B, M-3 and Low-Clearance M-3 Switch Machines with MCC

Switch Machines and Associated Equipment Ansaldo STS USA M-23A, M-23B, M-3 and Low-Clearance M-3 Switch Machines with MCC ASTS USA s style M Electric Switch Machines are rugged, reliable, units designed for any installation where electric power is available. The described in this RSE catalog section are equipped with ASTS USA s dependable Mechanical Circuit Controller (MCC). This device has provided dependable service on numerous freight railroads and mass transit lines for many decades. 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. Standard and Low-Clearance M-3 Switch Machines are recommended for applications where there is seldom a need to manually operate the switch. These three are available with a variety of operating speeds, gear ratios and motor voltages. Among other options are heaters in the CC or motor compartments (various wattages), CC without point detector latch, closed lock rod ports, fixed clutch slip setting at 14 or 20 Amps and aluminum exterior paint. General Description Basic Machine 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 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 require a somewhat higher clearance than the Standard M-3 or Low-Clearance 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-Clearance 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- Clearance M-3 ideal for third-rail transit applications where additional clearance is needed for the vehicle pick-up shoe. The point detector bar can be vertically lifted from the machine, allowing easy handling in tight confines. Left and right-hand versions of this are available, each with a single operating voltage, gear ratio and wire control scheme. These are equipped with circuit controller and motor compartment heaters, and point detector latch. 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. 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 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 provides for simpler 3-wire control. (Permanent magnet motors are also available for retrofitting older models of these switch ; see RSE-6A4.) To order, call 1-800-652-7276 www.ansaldo-sts.com, p. 1

Ansaldo STS USA M-23A, M-23B, M-3 and Low-Clearance M-23A and M-23B Switch Machine with Mechanical Circuit Controller (MCC) General Description (cont d) 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. Several different gear ratios are used to provide various operating speeds (see ordering tabulations for available ratios). The Low-Clearance M-3 incorporates the same basic gear train concept as the other style M, and is provided with a single gear ratio of 189:1. In all style M, 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 style M switch 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-3 Machines for Replacement of Alstom/GRS Machines with 2-Wire Control Four versions of the M-3 Switch Machine with an MCC can be used to replace selected Alstom with 2-wire control. These include two 15W/115V heaters (for motor and circuit controller). The N451160-0338 and -0339 are L.H. for R.H. indication, or R.H. for L.H. indication. Refer to ordering tabulation on catalog page 11 for specific part numbers. Contact your ASTS USA Account Executive or request Service Manual SM-6263 for additional information.
