Wavetrak Electronics WT-RC User manual

This manual applies to the WT-RCreceiver when
used to locate all makes and models of 22 Hz and
Wavetrak coded transmitters.

The Wavetrak WT-RCreceiver kit comes with the following
pieces of equipment:
A Wavetrak WT-RCReceiver
An external antenna (optional to use)
A 50’ extension cable for the external antenna
A hard carrying case
Optional accessories available from Wavetrak, which may be
included in your kit, are:
A strobe attachment (for indicating pig passage remotely
by visual indication)

Power On/Off Button: Hold this button to turn on or turn off the
receiver.
Gain Level Indicators: This indicates how sensitive the receiver is
to incoming signal. This is adjusted by using the gain buttons on
the handle. If LEDs to the left are lit, this indicates lower gain,
while LEDs to the right indicate higher gain. If the gain is turned
up, the receiver will pick up signal from further away. However, it
will also pick up more electrical noise, and could result in a false
reading. It is recommended that the gain is set at a point where
the signal strength is the highest possible without picking up
electrical noise.
LED Light Signal Strength Indicators: These will light up when a
signal is detected. The LEDs correspond to the numbers on the
analog meter, from 1 to 10.The greater the signal, the further to
the right the LEDs will light.

Analog Meter Signal Strength Indicator: The analog needle will
move to indicate how strong the incoming signal is. 0 indicates no
signal, and 10 shows maximum signal strength. The numbers on
the meter correspond with the LED light signal strength
indicators.
Transmitter Code Indicators: These LEDs indicate the type of
transmitter signal the unit is receiving. “22Hz” indicates that the
receiver is detecting a standard 22 Hz transmitter signal. The “A”,
“B” and “C” lights indicate that the receiver is detecting a Code A,
B, or C transmitter signal, respectively. When receiving a signal
from a coded transmitter, the “22Hz” light will light before the
appropriate code detect light is lit.
Low Battery Indicator: This LED light will flash when the batteries
in the receiver are discharged. Put new C cell (LR14) alkaline
batteries into the unit as soon as possible.
Antenna Attachment Indicator: This LED will light up when an
external antenna is plugged into the receiver. WARNING: This
indicator will light up whenever an antenna is plugged in and
detected. It does not indicate that the antenna is functional. It is
possible for the antenna to be detected even if the antenna is
damaged and not able to receive a signal.
Light Senor: This detects the ambient light conditions. When it is
dark, the panel backlight will turn on. Keep this sensor clear of
debris, as it will turn the backlight on even when it is not needed.
Gain Switch: The up and down arrow buttons on the gain switch
controls the gain setting of the electronics. Press up to make the
receiver more sensitive, and down to make it less sensitive.
Buzzer Off Switch: Press this to toggle whether the buzzer is
operational or not. The status of the buzzer is indicated by the
word Off being lit in red when the buzzer is disabled.
Buzzer Off Indicator: This LED will light up when the buzzer is
disabled.

To turn on the receiver, press and hold down the power button
until the unit powers on. All the front panel lights should turn on
briefly as a test, and the ring around the power button will light up
to indicate the receiver is on.
To turn off the receiver, simply press and hold the power button
down again until the power light (the lighted ring around the
power button) turns off.
The receiver is equipped with an internal antenna, so you can
begin tracking right away. No attachments are needed. The
receiver gain is controlled with the gain adjustment buttons on
the top of the receiver handle. Pressing the red up arrow will
increase the gain; the blue down arrow will decrease the gain. The
current gain setting is indicated on the row of lights labeled
“GAIN”, with the rightmost light being full gain, and the leftmost
being no gain. When you turn the receiver on it will return to the
last gain setting used.
If a signal is received, it will be shown on the signal meter. The
signal lights above the meter follow the meter’s position. If the
signal is a transmitter’s 22Hz signal, the 22 Hz light will turn on
and the buzzer will sound. If the signal is a Wavetrak coded signal
(from a coded transmitter) the appropriate code will light. For
example, once a Wavetrak code C transmitter is in range, it will be
indicated by the 22Hz light and the buzzer turning on for
approximately ½ a second, followed by the C light briefly lighting
to indicate that it has a C code. Then after a brief pause the
sequence will repeat as long as the transmitter is in range.
The buzzer can be silenced, if desired. Use the buzzer off button
on the handle. On power up, the receiver keeps the last setting.

There are two jacks located on the front of the receiver. The 3
connector jack is for an optional strobe attachment, and the 4
connector jack is for connecting an external antenna or external
antenna extension cable. Both receptacles are designed so that
each attachment will only plug into the correct jack.
The included external antenna can be used to both increase range
and more effectively pinpoint a transmitter’s location. To use it,
plug it into the antenna connector on the front end of the
receiver. You can also attach the extension cable, to increase the
cable length to the antenna. When the antenna is connected and
detected, the receiver will switch from the internal antenna to the
external one. The ANT light on the front panel will light up,
indicating that the receiver senses the external antenna and has
switched over.
WARNING: This indicator will light up whenever an antenna is
plugged in and detected. It does not indicate that the antenna is
functional. It is possible for the antenna to be detected even if the
antenna is damaged and not able to receive a signal. Functional
tests to check a transmitter and receiver’s operation are always
recommended.
To connect the optional strobe attachment, simply plug it into the
front end panel, as you do with the external antenna. It is best to
check the operation of the strobe with a functional transmitter, to
make sure that it is connected properly and in working order. The
strobe will only flash when the 22Hz light is on and the buzzer
sounds on the receiver.
The backlight on the receiver, which backlights both the meter
and panel text will turn on automatically when the ambient light
becomes dim.

WARNING: NEVER UNSCREW OR OPEN THE BATTERY
COMPARTMENT WHILE IN A HAZARDOUS ENVIRONMENT.
1) Before replacing the battery compartment visually inspect the
gasket to ensure a proper seal.
2) Once batteries are installed, ensure all four screws are tight,
securing the battery box to the chassis.
WARNING: NEVER UNSCREW OR OPEN THE BATTERY
COMPARTMENT WHILE IN A HAZARDOUS ENVIRONMENT
To change the batteries, unscrew the 4 screws located on the
battery box (the back end of the receiver). Remove the battery
box from the receiver. Do not unscrew the 4 screws located on
the front of the receiver (near the meter) –there are no user
serviceable parts inside. Doing this can void your warranty.
Replace the 8 C cell alkaline (LR14) batteries with fresh batteries
of the same type. Wavetrak recommends using Duracell Procell
PC1400 batteries. Ensure that the batteries are inserted in the
orientation marked on the battery holders, and that all of the
batteries are making contact.
Before replacing the battery box and refastening the 4 screws,
check the condition of the battery box gasket that seals to the
face of the receiver. If it is damaged, the unit will no longer be
weather-tight; contact Wavetrak for a replacement gasket.

Wavetrak can check the calibration of the Receiver and re-
calibrate as necessary. Contact Wavetrak for more information.
Power up the transmitter. Before placing it into use in the
pipeline, a function test should be conducted with the receiver to
ensure that the correct signal strength is being generated by the
transmitter, and that the receiver is operational. Once the open
air test is complete, fasten the transmitter to the tool. When
installing the transmitter into the pig, ensure that it is placed cap
end first. Also, check that there is enough clearance between the
transmitter and the pipe wall so that there is no danger of the
transmitter rubbing on the pipe. (Refer to: MOUNTING
PRECATIONS in the WT-Ex Transmitter User Manual). Locate the
transmitter and ensure transmitter is operational prior to launch.
(Refer to: LOCATING THE TRANSMITTER AT THE LAUNCH / TRAP).
WARNING: WHEN MOUNTING A WAVETRAK TRANSMITTER,
ENSURE THAT THE TRANSMITTER WILL AT NO TIME CONTACT
THE PIPE WALL WHILE THE PIG IS TRAVELLING THROUGH THE
PIPELINE. THIS WILL CAUSE DAMAGE AND WILL VOID THE
WARRANTY. FOR Ex MODEL TRANSMITTERS, THIS WILL ALSO
CAUSE THE TRANSMITTER’S EXPLOSION PROOF FEATURES TO
LOSE THEIR EFFECTIVENESS.
