CD42-STS Subsea Diver/ROV Pig Locaon and Tracking System
Page 4 of 36
The CD42-STS is a pipeline pig locang and tracking receiver that detects
pulsing signals emied by electromagnec transmiers in a subsea
pipeline.
The transmier signal strength is displayed on an LED array which can
be easily seen by a diver or ROV operator who is tracking moving pigs
and/or locang a staonary or stuck pig.
The CD42-STS may be deployed below the ocean to depths of 8,0000
[2,439 m] and is designed to be either carried by a diver or ROV. It is
rated for a maximum pressure of 3,650 psi [245 bar].
The CD42-STS is constructed of stainless steel. A control buon adjusts
antenna gain, which is displayed on an array of 16 light-eming
diodes (LED). The LEDS also indicate
transmier proximity when tracking
or locang a pig. Diver handles may be
removed and replaced with oponal
“shtail” ROV handles (see pg. 24).

The 26.4-in. [670.5 mm] antenna may
be removed and replaced with an oponal
Close Proximity Antenna (CPA). The CPA is sensive
only to very near signals
and designed for use where
mulple pigs are extremely close to one
another such as in launchers and receivers.
POWER
The CD42-STS is powered by six (6) D-cell alkaline baeries. The
baeries are located in the unit’s stainless steel housing. Changing
these baeries requires disassembly of the housing (see pg. 18).
The CD42-STS will operate for up to 60 hours (2.5 days) on a change of
baeries.
The CD42-STS can track and locate any pig or inline inspecon (ILI) tool
equipped with a 22 Hz electromagnec transmier. Shown here are
some of the 22 Hz transmiers manufactured by CDI.

The CD42-STS receiver is assembled at CDI and should be ready for
operaon upon receipt. The baeries are installed and the unit is sealed
and tested for funconality just prior to shipment.
Check for any damage to the CD42-STS receiver aer removal from
the shipping container. Check the antenna for any bends, dents, or
deformies.

Remove the large hexagonal plug located
on the antenna side of the system
to access the power switch.
(You’ll need a 1–5/8-in. open-end wrench
or adjustable wrench to loosen plug).
Press the red pushbuon switch
to toggle the system power
ON/OFF.
Inspect O-ring and O-ring groove
before replacing plug (see pg. 21 for
O-Ring inspecon and maintenance
informaon).
Replace plug. Tighten unl snug (do not over-ghten).

When the unit is rst powered on, the unit will perform a self-check.
This is indicated by a rapid back and forth scrolling of the LED array.
The LEDs on each side will ash in succession from boom to top and
back down ve mes as shown here.
The CD42-STS is operaonal when the self-check has completed, but
you may wish to adjust the signal gain before placing the unit into
service. (See following pages.)

When the self-check is complete, the display will indicate the last
signal gain (sensivity) seng stored in the memory by ashing three
mes and then remain on for
another three seconds. Here,
the unit has been set to a
relavely low gain level of 3.
The gain readout will
remain on for 3 seconds
then the display will go
dark.
The CD42-STS
receiver is now in the
operaonal mode and is looking for
electromagnec pulses. To verify that
the unit is operang prior to deployment, bump the antenna with your
hand. The displays LEDs will jump and conrm it is operang.
Press and hold the control buon momentarily to redisplay the current
gain seng. To increase signal gain,
connue to hold the buon
down. Aer approximately
3 seconds, you will see the LEDs
light in succession from
le to right as the
gain level increases.
Each increment will
be set in 1.25-second
intervals.
Aer the gain control
reaches the full-scale posion it will
cycle to the zero gain posion. Keeping the buon pressed will restart
the gain increase cycle.

No LEDs lit indicate zero gain posion. Low gain sengs (1,2, and 3) are
useful when the CD42-STS is used in very close proximity to a transmier
such as at a pig launcher or receiver.
The gain seng is stored in non-volale memory. It is retained when the
receiver is powered down and even if baeries are removed.
When the unit is powered back up your gain seng will be displayed in
the power ON sequence.
