1GENERAL DESCRIPTION

The ST-101 Signal Transmitter is a signal transmitter used to transmit signals on twisted pair telephone lines for

locating resistive faults when used with a receiver such as the AALogic SR-101.

1.1 FEATURES

The features of the ST-101 Signal Transmitter include:

Five frequencies: 335Hz, 577Hz, 987Hz, 2KHz, and 4KHz.

Simple user interface and operation.

Rechargeable internal battery

Water resistant, lockable case

1.2 HOW FAULT LOCATING WORKS

The ST-101 helps locate faults by transmitting a signal on a pair with a resistive fault. The technician uses a

signal receiver, such as the AALogic SR-101, to trace the signal on the cable. The current flowing in the

pair causes the signal to be radiated. The highly sensitive receiver, tuned to the same frequency as the

transmitted signal, allows the technician to locate the fault by observing the changes in the signal

strength. The signal significantly increases or decreases as the technician moves past the fault.

The ST-101 offers a high voltage, low current signal that is compatible with receivers capable of

monitoring one of the five signal frequencies.

This manual describes the setup of the transmitter for the various faults to be located. It is important that

the technician setup the system as described to obtain reliable results. In all cases, a complete circuit,

through the fault, is required.

The receiver operating instructions must also be used for effective location of faults.

2WHAT IS INCLUDED

The ST-101 includes the following:

ST-101 Signal Transmitter

Test cord with clips

Charger

USB Drive with manual

3FRONT PANEL

The ST-101 main display is shown in the following picture.

The PWR/CLR on the lower left is used to Exit any screen or to turn the unit off.

Keys F1, F2, and F3 are screen dependent.

oThe F1 START key starts sending a signal at the currently set frequency.

oThe AUTO-SET key initiates an automatic setup feature. The ST-101 will scan the pair and

attempt to determine an optimum frequency and initial power LEVEL.

The FREQ key allows for frequency selection.

The LEVEL key is used to adjust the power output LEVEL when transmitting the signal.

The CFG key allows the user to set the CONTRAST, BACKLITE, and TONE mode options.

The Charger jack (12V) is used to charge the internal battery. Only use the supplied charger to

charge the ST-101 to avoid damage to the unit.

The CHGR lights above the display has a red light when the charger is connected. A green light is on

when the battery is charging.

The pair cord plugs in on the right side of the case as indicated on the front panel.

4DISPLAY

The Main screen is shown in the following picture.

From this screen, the F1 key is labelled START. This begins the transmitting operation using the current

frequency shown on the screen and automatically adjusts the power output. The F2 is not used from the Main

screen. The F3 key is labelled AUTO-SET and begins the transmitting operation and automatically adjusts the

frequency and the power output.

The display is backlight and contrast adjustable by pressing the CFG key.

A battery charge indicator is in the top left corner. Always check this before use. If only one segment is shown,

charge the unit as soon as practical.

5BEFORE FIRST USE

5.1 BATTERY CHARGING

The ST-101 should be charged before the first use. Use only the supplied power supply with the ST-101.

AALogic recommends charging a minimum of four hours before the first use. In normal operation, the ST-

101 should be fully charged after two to three hours depending on the current charge level.

5.2 CONFIGURATION OPTIONS

This section describes the configuration options for the ST-101.

5.2.1 Display Setup –Contrast and Backlite

Press the CFG key to adjust the display for personal preferences. The Contrast and Backlite LEVELs can

both be adjusted. It may be easier to increase the Backlite to a comfortable LEVEL first and then adjust

the Contrast.

5.2.2 Tone Configurations

The ST-101 has two tone modes, SOLID and Pulsed, selected from the CFG screen. The SOLID tone should

be used in most cases. The pulsed mode provides an ON/OFF/ON tone that may be useful when more

than one cable appears to have tone. The SOLID mode may be easier to use once the proper cable has

been identified. Some receivers may not display the pulsed tone as well when locating a fault.

6SETUP

The ST-101 is designed to simplify setup. The directions provided with the receiver should be reviewed to

ensure the best success in locating the fault.

6.1 SAFETY

All prescribed safety precautions and procedures must be observed while using the ST-101. Failure to do so can result in serious injury or

death.

Caution should be used when foreign voltage is detected on a pair. The voltage may be a power source capable

of injury to technicians and possible damage to equipment. Foreign voltage should be removed prior to locating

for best results.

6.2 FAULT PRE-TESTING

The technician must identify the type of fault before attempting location. The ST-101 connection and receiver

indication vary depending on the type of fault. Pair test equipment, such as the AALogic D-105, ATV-25, or

similar test sets, may be used to identify the type of fault on the pair.

Version 1.0.2 5

The approximate location of the Fault should also be estimated by the pair test equipment. The estimate and

the cable documentation are useful in sectioning the cable for Fault location. The physical location and the

location provided by electrical measurements may not agree.

6.3 SECTIONING

The fault should be isolated to as small a cable section as practical prior to attempting fault location. This will

improve the reliability of the fault indications and reduce the time needed to locate the fault. Existing practice

should be followed for sectioning.

The faulted pair being located should be isolated from the CO and any terminating (premise) equipment during

the location.

6.4 CONNECTIONS

The ST-101 includes a cord with pair clips. This cord is plugged into the jack on the right side. Only the pair cord

supplied with the ST-101 should be used.

Fault location depends on current flow. The black and red clips must be connected to each side of a resistive

fault as follows:

6.5 SPLIT FAULTS

During identification of the split, the technician must identify the two pairs involved in the split and if the tips or

rings are split. The diagram below shows a split and how to place temporary short at the end of the section.
