Safety
At UEMSI/HTV, we care about operator safety. We recommend that all field personnel
operating pipeline inspection equipment should be aware of all safety precautions listed in
this manual and other safety data in compliance with OSHA standards. Failure to follow
these precautions may result in injury.
Safety Notations
This manual contains specific operating and maintenance procedures. Particular parts of
these procedures contain instructions, which must be strictly adhered to. These instructions
have been categorized under the following three headings: WARNING, CAUTION and
NOTE. The significance of each heading is listed below.
Maintenance, operating procedures, or techniques that if not followed, may result in injury.
Maintenance, operating procedures, or techniques that if not followed, may result in
equipment damage.
Maintenance, operating procedures or techniques to be especially aware of.
5
Read Instructions
All the safety and operating instructions should be read before the unit is operated.
Safety Guideline for Power Cord and Power Outlet
Use a power cable that is properly grounded. The female receptacle of the cord set must
meet IEC-60320 requirements. (Fig. 1)
In the U.S. and Canada, the male plug is NEMA5-15 style UL/CSA labeled termination (Fig.
2). The plug is equipped with a grounding pin. Do not defeat the safety purpose of the
grounding pin.
Use a power outlet with a three-terminal grounded receptacle. The unit should be operated
only from the type of power source indicated on the rating plate.
DC Operating Guidelines
This unit is designed for use with a 12V DC automotive power supply. Never use it in a truck,
bus, or any other vehicle that has a 24V power supply. Allow the vehicle to run during
operation, as this will charge the battery circuit and supply an efficient source to the unit.
Servicing
Do not attempt to service this unit yourself as opening may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service personnel.
6
Environmental Range of Operation and Storage
Never leave the PCU or camera reel exposed to temperature extremes or strong, direct
sunlight. Leaving it in an enclosed vehicle, in direct sunlight, near a heater, etc. can cause
deformation of the case and electrical cables.
Using this product in areas that are colder than 14°F (-10°C) or hotter than 158°F (70°C) can
result in electronic component malfunction.
Do not operate the PCU for two hours if condensation has formed on the unit. Let the system
stand with the power off during this time. Condensation will form on the unit when it is moved
from a cold to a warm place.
Storage Guidelines
When storing the product follow these guidelines:
Clean the push-cable, reel, and camera of any debris before storage.
Wind the interconnect cable around the hooks provided on the push-reel.
Store any power cables or accessories in the storage compartment.
Product Usage Guidelines
DO NOT operate the unit in or near flammable liquids.
DO NOT enter a pipeline before disconnecting power to all electrical pumps or valves
attached to it.
DO meter for explosive gasses and ventilate the area before entering a pipeline.
DO connect generator-to-earth ground when operating on generator power.
DO keep the unit and area clean of bio-hazards.

SYSTEM DESCRIPTION

General
The UEMSI/HTV™ U-Vue™ push camera system is a lightweight, rugged, portable unit
capable of meeting a wide variety of small diameter pipe inspection requirements. The image
sensor of the camera is a solid-state charge couple device (CCD) with a high degree of
sensitivity. The lighthead contains either 15 or 21 LEDs, depending on the camera head,
which are behind a Lexan® shield. They can illuminate pipe up to 10” in diameter, depending
which camera head is used and the pipe conditions.
The monitor and controls are contained in a durable, water resistant, and impact
resistant carrying case. When the case is open, the unit is also water resistant,
including the monitor, speakers, controls, and keyboard.
The system can be powered by either 120 volt 60 Hz AC line power, or a 12-volt DC
automotive lighter receptacle.
System Components
Figure 1.1 shows a block diagram of the system components. The basic system consists of a
power control unit (PCU), reel, and camera head.
Figure 1.1
Camera Head
The camera head (Fig. 1.2) consists of a sealed housing containing the CCD image sensor,
lens assembly, lighthead, and electronic circuitry.

Figure 1.2
The lighthead dome cover contains two O-rings and is
fastened with three stainless steel flathead screws. While
the lighthead dome cover can be removed for service,
opening the camera further by an unauthorized service
technician is not recommended and will void the warranty.
The rear of the camera is terminated with a built-in six pin
male connector, which mates with the push cable
connector. They are held together with three stainless steel combination head screws. An
O-ring has been placed between the camera and the cable connector to seal out liquids.
Procedures for camera maintenance are covered in the maintenance section of this manual.
Push Reel
The push reel (Fig. 1.3) safely stores and dispenses the video push cable and camera head.
It is lightweight and contains wheels for mobility.
A brake handle is provided to keep the cable basket from rotating when transporting the unit.
After the basket is locked, the brake handle can be repositioned by lifting and rotating into a
stored position.
The push reel also features a quick disconnect block termination. This feature allows the
user to easily swap out push cable by simply disconnecting the cable from a single
connector.
The interconnect cable is used for all electrical
connections from the power control unit (PCU) to the
push reel. Although the interconnect cable can be
removed from the reel, brackets are provided for windup
storage.

Power Control Unit (PCU)
Figure 1.4 show the features of the PCU. The lid is comprised of the 10.4” sunlight readable
color LCD monitor, and the DVR control panel. The lower portion of the case is comprised of
the interface panel with camera controls, and the storage compartment.

System Controls
The system control portion contains the necessary controls for operation and status of the
system. The following is a description of each component along with its associated functions.
Power Switch
There is only one toggle switch that controls both AC and DC power to the unit. The switch is
either “ON” or “OFF”. The switch is located on the lower faceplate.
AC Power
Controls power to the system when the 120 volt line cord is being used.
DC Power
Controls power to the system when the 12 volt DC automotive plug is being used.
