The CD42-STS is a pipeline pig locang and tracking receiver that detects
pulsing signals emied by electromagnec transmiers in a subsea
pipeline.
The transmier 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 locang a staonary 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 buon adjusts
antenna gain, which is displayed on an array of 16 light-eming
diodes (LED). The LEDS also indicate
transmier proximity when tracking
or locang a pig. Diver handles may be
removed and replaced with oponal
“shtail” ROV handles (see pg. 24).

The 26.4-in. [670.5 mm] antenna may
be removed and replaced with an oponal
Close Proximity Antenna (CPA). The CPA is sensive
only to very near signals
and designed for use where
mulple 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 baeries. The
baeries are located in the unit’s stainless steel housing. Changing
these baeries 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
baeries.

The CD42-STS can track and locate any pig or inline inspecon (ILI) tool
equipped with a 22 Hz electromagnec transmier. Shown here are
some of the 22 Hz transmiers manufactured by CDI.

The CD42-STS receiver is assembled at CDI and should be ready for
operaon upon receipt. The baeries are installed and the unit is sealed
and tested for funconality just prior to shipment.
Check for any damage to the CD42-STS receiver aer removal from
the shipping container. Check the antenna for any bends, dents, or
deformies.

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 pushbuon switch
to toggle the system power
ON/OFF.
Inspect O-ring and O-ring groove
before replacing plug (see pg. 21 for
O-Ring inspecon and maintenance
informaon).
Replace plug. Tighten unl 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 boom to top and
back down ve mes as shown here.
The CD42-STS is operaonal 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 (sensivity) seng stored in the memory by ashing three
mes and then remain on for
another three seconds. Here,
the unit has been set to a
relavely 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
operaonal mode and is looking for
electromagnec pulses. To verify that
the unit is operang prior to deployment, bump the antenna with your
hand. The displays LEDs will jump and conrm it is operang.

Press and hold the control buon momentarily to redisplay the current
gain seng. To increase signal gain,
connue to hold the buon
down. Aer 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.
Aer the gain control
reaches the full-scale posion it will
cycle to the zero gain posion. Keeping the buon pressed will restart
the gain increase cycle.

No LEDs lit indicate zero gain posion. Low gain sengs (1,2, and 3) are
useful when the CD42-STS is used in very close proximity to a transmier
such as at a pig launcher or receiver.
The gain seng is stored in non-volale memory. It is retained when the
receiver is powered down and even if baeries are removed.
When the unit is powered back up your gain seng will be displayed in
the power ON sequence.
