410 Signal Test Timer
The Model 410 Signal Test Timer has several capabilities that address various operations and signal related needs.

  1. Portable. Operates on furnished, plug-in 120VAC to 12VDC power supply or local battery, or Battery Kit accessories. Can also be installed on a permanent basis.
  2. Data from tests is recorded and can be downloaded. Download is implemented with the use of HyperTerminal (r), a program provided with Windows(r) operating system, or other standard communication program, through a USB port. Complete instructions for downloading, the printing of reports, etc., are provided in the Instruction Manual for the Model 410 Signal Test Timer.
  3. Determines Train Speed (PN: 410-18 Train Speed Transducer Kit and PN: 330-23T Battery Kit or 330-24 Battery Kit req'd) - install Train Detector Transducers on same rail, 100 feet apart. Connect cables to the Train Detector Transducers and the Timer Speed Interface. Attach power source (Battery Kit, etc.) to the Timer. Connect Timer Speed Interface to the Timer and wait for trains to pass. The installation process takes approximately thirty minutes to complete, once access to the track has been granted by the dispatcher. See hook-up diagram below.
  4. Determines Activation Lag & Throw Times of Switch Machines - Dry set of contacts from switch machine normal and reverse indications are connected to the Form C Inputs and normal and reverse voltages from the switch machine control point are applied to the Automatic Inputs.
  5. Determines Code Relay Rates - connect front and back contact of code relay to Form C Inputs.
  6. Determines Transition Times of Searchlight Signals - Connect normal and reverse contacts of searchlight signal to Form C Inputs
  7. Determines Activation Times of Solenoids equipped with contacts.
Typical field hook-up.

Model 322 Shunt and Coupler Tester

Download PDF File
 The widespread use of motion sensing and constant warning time track circuits has resulted in the proliferation of wide and narrow band shunts and IJ couplers. Many times the circuits are overlapped, resulting in ever-increasing problems of turning and frequency conflict. The troubleshooter needs to know the complete range of characteristics of the shunts and couplers with which he is dealing, when attempting to identify the source of circuit malfunctions.

This device permits the signalman to know the frequencies, tuning characteristics, attenuation and thru-put capacities of each device in the approach "network", empowering him to relatively quickly determine the source of the problem.

  1. Identify center frequencies of shunts, couplers and related transmitters
  2. Determine termination and signal thru-put capacities
  3. With data from tester, rule out shunts as sources of tail ring
  4. Adjust turnable couplers and shunts prior to installation
  5. Test for DC leakage
  6. Frequency range: 10HZ to 5120HZ
  7. For field or shop use
  8. Operates on rechargable, 12VDC, 1.2AH lead acid battery


Application
This highly portable device permits the maintainer to bridge or terminate signals into the shunts or couplers under test. It can be moved to the area of the track where the shunts or couplers are in service, maximizing effectiveness and minimizing time required to perform the tests.

"Sweep" Function automatically checks full range for tuning points. Graphic display pictorially shows frequency curve and tuning points.

Seperate inputs for Tuning, Leakage and Frequency Meter Tests reduce potential for resistance in switch contacts to adversely affect test results.

Model 236-382 Obstruction Gauge

 Obstruction Gauges are used to comply with FRA required tests of track switches. They are used to determine if a power operated switch or a hand operated switch and lock movement has been adjusted properly. Proper adjustment is deemed to occur when the switch cannot be locked up when the appropriately sized obstruction is placed between the switch point and stock rail, six inches from the end of the switch point.

The design concept S&C Distribution Company has employed provides four gap gauges of standard values and in combinations that enable fast change over to values used for different tests. The design also assures more stable, self-retaining mounting to the rail during tests.

Gauge No. 236-382B (Dwg. To the left) offers the gap gauges most common to signal testing (AREMA standard). Gauge No. 236-382A provides a 5/16th inch gap gauge that addresses special adjustment to M-23 Switch Machines where the practice of floating off the lock rods occurs. At locations where a split point derail is operated with a switch machine or a hand operated switch and lock movement, we offer a special gauge, No. 236-382C, where a ½ inch gap gauge is provided.
