http://scbist.com/scb/uploaded/1_676786786789789.jpg

The GM4000A™ Switch Machine incorporates all ofthe features required to meet today's rigorous interlocking demands. The machine is easy to install, operate and maintain. One model does it all! It is truly universal. There is no need to purchase different machines for different locations because this unit is a drop-in replacement for most industry machines.

Large inventories of spare parts are reduced due to the GM4000A™'s Modularity Design Concept. The machine uses 50% fewer parts than traditional switch machines and it is adaptable to nearly all site-specific requirements without having to make application or electrical changes.

Advanced Drive Train

• Maintenance free gearbox, no lubrication required

Main Drive Module

• Single and dual control versions
• Hand throw and hand crank permits track switching without electrical power
• Low 8.75 inch profile

Lock Rod Module

• Wide or narrow notch designs
• 3.5 to 6.5 inch adjustable throw
• Left or right-hand field configurable

Accurate Point Detection System

• Indicates normal or reverse switch position with latchout
• Breaks indication if point moves away from stockrail
• Configurable for restorable and non-restorable latchout modes

Split Link Cam Bar

• Prevents Lock Rod shaving
• Allows flagging over a fouled switch without damaging hand throw arm
• Permits throw bar to complete full stroke when lock rod is fouled

Optional Heaters

GM4000A™ Enhanced Controller

FEATURES
• 5 Seconds Electronic Overload Protection (Internal)

No overload relays needed. Internal overload protection electronics are included.

• Trackside Electrical Operation

The controller allows maintainers the ability to operate the machine electrically while performing maintenance or testing, rather than having to use the Hand-Crank.

• Universal 2, 3, 4, & 5 Wire Mode Compatible

Allows flexibility to design & integrate the GM4000A to any existing wiring, without field wiring changes.

• 5-Second Obstruction Cut-Off = NO Clutch

The controller is designed to electrically cut power to the motor if an obstruction is encountered between the points. The machine does not have a mechanical clutch, which means less maintenance.

Reference LED's for Troubleshooting

The top surface of the Controller is clustered with LED's to help diagnose any potential fault.

Speed, Current, & Selection

The controller allows the maintainer to select a 4 second or 15 second throw time. The controller allows for a Low or High Current draw.

Universal Power AC / DC

The controller will operate with either AC or DC Power.

Voltage Frequency

The controller will operate at 50Hz, 60Hz, or 100Hz AC. This allows designers more flexibility for new-work construction.

Control Voltage

The controller accepts Control Voltages in the range of 9-35 VDC.

The “NEW” GM4000A™ Switch Machine incorporates all of the features required to meet today's interlocking demands. The machine is easy to specify, order, install and maintain, because one model does it all.
It's truly universal; there is no need to stock different versions or maintain large inventories of spare parts. The machine uses 50% fewer parts than traditional electric switch machines, and it's easily field-modified to match
specific site requirements.
With a low profile, the “NEW” GM4000A™ is especially well-suited for mainline freight or subway and rapidtransit applications. With the capability to deliver more than 4,000 lbs of thrust, this machine is an ideal solution
for long turnouts, installations plagued by snow and ice or short turnouts with welded heal blocks. A maintenance-free motor eliminates brushes and a dynamic snubbing device.
The machine’s solid-state amplifier eliminates a mechanical clutch and provides universal power (85 to 160V AC/DC or 13 to 160V DC), field-configurable control (3, 4 or 5 wire), as well as consistent five-second
overload protection.
The “NEW” GM4000A™ point-detection system indicates normal or reverse switch positions and breaks indication if a switch-point has moved away from the stock rail. This system is supplied with latch-out functionality
that can be customer configured (restoring, non- restoring or disabled). Field -obstruction testing and adjustments are simplified with the help of LEDs and a point-detector adjusting nut that is exposed and easy to adjust.
The “NEW” GM4000A™ is field-configurable for single-or-dual control and right- or left-hand operation. The machine’s universal footprint matches all industry standard layouts.
