4000 Switch Machine - Alstom

FEATURESThe GM4000 is designed for long life and low maintenance, and helps reduce inventory due toits field configurable change-out design. Its long life and low maintenance are attributable to alow stressed mechanical system, dry film lubrication (DFL), brushless motor, solid stateamplifier, and significantly fewer parts than existing switch machines. The ease of fieldconfigurable change out is the result of a modular design concept with fewer and simplifiedadjustments.The switch machine can be manually operated, utilizing supplied power, through a manualoperation switch located near the motor. The switch machine can be manually operated, withoututilizing supplied power, through the use of the hand-throw lever or hand crank. The hand crankoperation is provided for making or checking setup adjustments when power is not available.When power is available, manual operation through the use of the manual operation switch isrecommended. These machine operating procedures are described in Section 2 of this manual.Modular DesignThe modular design of the GM4000 allows for ease of assembly and corrective maintenance.Module locating pins in the switch machine base and a modular weight limit of 85 pounds, withmost module weight less than 50 pounds, make it possible to remove and replace switch machinemodules at trackside. Module removal and replacement procedures are described in Section 6 ofthis manual.Configurable LatchoutThe latchout capabilities of the GM4000 are configurable for location requirements and can beimplemented or removed from the GM4000. Implemented latchout can be set for a restorable ornon-restorable configuration. This feature is described in Section 2 of this manual.Operating Power ConfigurationsThe GM4000 functions without additional hardware in a number of supplied power conditions(24 VDC, 110 VDC, or 110 VAC). This feature is described in the following sections of thismanual.Manual Operation SwitchThe GM4000 can be field operated under power as long as a switch call is present and the switchmachine amplifier is set in the “Local” operation mode. This operation is described in thefollowing sections of this manual.P2444, Rev. Jan/07 1-2ALSTOM Signaling Inc.
