1 General Safety
1. General Safety
This document contains essential advice for installing and operating the Vivax-
Metrotech FLS-2 transmitter. Follow these safety instructions when handling the
transmitter, its modules, or troubleshooting.
NOTE
The manufacturer is not liable for damages to materials or harm
to humans due to the non-observance of the instructions and
safety advice provided in this document. Therefore, this document
should be provided and reviewed by all personnel associated with
its installation and use.
• Intended personnel
Vivax-Metrotech utility line locators are intended for use by utility
and contractor professionals. Safety hazards for underground utility
access areas include electrical shock, explosive gases, toxic fumes,
and a potential influence on communications and control systems
such as traffic control and railroad crossings.
• Intended application
A safe operation is only achieved by using the transmitter for its
intended purpose. Using the transmitter for other purposes may
lead to human danger and equipment damage. Do not exceed the
limits described in this document.
• Output Signal and fiber optic cables
The transmitter output signal is high voltage. When the transmitter
sends a signal, the fiber optic cable sheath and connections may be
energized up to 300V AC TO 450V DC. Keep a safe distance from
these cables and connections.
• Lightning strikes
The transmitter must be installed with proper lightning protection.
Damage to the transmitter may occur if it is not correctly installed
and protected from lightning strikes. We do not recommend that
you operate or perform maintenance on the transmitter if there is a
pending electrical storm near the transmitter or the buried cable.
• Modules
Before removing any modules, turn the rear power switch off. The
modules were not designed to be hot-swappable.

1 General Safety
• Malfunctioning behavior
Use the transmitter only when it is working correctly. When
irregularities or malfunctions appear that this document cannot
resolve, the transmitter must immediately be put out of operation
and marked as not functional. Contact technical support. Only
operate the transmitter after resolving the malfunction.
• Repair and maintenance
Service and repairs can be performed only by Vivax-Metrotech
Corporation.

4. Introduction
This chapter contains the following sections:
• System Overview
• Features
• Transmitter Signals
• Modular Design
• Specifications
4.1 System Overview
The Vivax-Metrotech FLS-2 transmitter and vLoc series receivers locate underground
fiber optic cables. This user manual covers the FLS-2 transmitter. For instructions
about using the vLoc series receivers, see their instruction manuals.
The FLS-2 transmitter sends a predefined signal lower than 10 kHz along the metallic
sheath surrounding the fiber optic cable, generating an electromagnetic field for the
length of the cable.
The receiver is outside to locate the electromagnetic field around the underground
cable. When using one of the predefined transmitter signals, the receiver can estimate
the relative position and path of the cable.
Figure 4-1 FLS-2 Transmitter and Receiver
4.2 Transmitter Signals
The transmitter is a signal generator that consists of one or more programmed
frequencies that allow you to locate and trace the fiber optic cable. The predefined
frequencies are:

™

Signal Direction (SD): SD512 (256 Hz and 512 Hz)
Locate Signal (LS): LF512 (512 Hz)
Extremely Low Frequencies (ELF): • ELF10
• Other ELFs available upon request
Note: Other frequencies may be available upon request.

5.3 Hand-Held Display Unit
The hand-held display unit controls the transmitter through its touch screen. The
display unit’s coiled cord plugs into the “Display” RJ11 connector on the front of the
control module, as shown in Figures 5-2. When not in use, store the display unit on the
bar in front of the Main Control module.
NOTE
For information about using the attached hand-held display unit,
see section 7.1, “Using the Hand-Held Display Unit.”
5.4 Overview of the Modules
This section briefly describes the transmitter modules, including differences between
the AC and DC systems. For information about removing or installing the modules, see
section 11.2, “Removing or Installing Modules.”
5.4.1 Main Control Module
The transmitter has a main control module installed horizontally in the front of FLS-2. Two
screws and two ejector handles secure it, figure 5-2 shows the main control module.
This module mainly controls the transmitter. It contains the firmware, memory, and
modem circuit. The front connectors are for an optional computer and the hand-held
display unit. The modem circuit connects to the telephone line through the rear RJ11
connector.
Figure 5-2 Main Control Module
5.4.2 Power Supply Module
The FLS-2 provides the flexibility to choose either AC or DC power supply. It is located
at the back of the transmitter and secured by screws.

5 Overview
5.4.3 Rear Module
The FLS transmitter has the option of 2-way, 4-way, or 16-way transmissions. This
module has the RJ-11 phone line connector for the modem, an RJ-45 network
connector for local area network (LAN) connection, a connector for 2-way or 4-way
relays, and the connector for the 16-way relay interface.
This module also contains the high-voltage output connector and the telemetry
connector.

6.4 Attaching the Rock Mounting Brackets
The transmitter ships with three sizes of standard and adjustable mounting brackets,
allowing for installation in 19, 23, or 24-inch racks. The FLS-2 transmitter ships with
the 19-inch standard rack mounting brackets already attached. The adjustable rack
mounting bracket kit allows you to adjust the horizontal front-to-back position of the
transmitter up to 5.25-inches (133.4mm). Figure 6-2 shows the left bracket for the
adjustable brackets.
Measure the rack width and use the following instructions if you need to change the
bracket size.
To remove and install the rack mounting brackets:
1. Remove the attached mounting brackets using the Philips-head screwdriver and
save the flat-head screws.
2. Attach the new brackets to the same place with the flat-head screws.
