Manual revision 016 Section 4: Deploying and Operating FastCAT SBE 49

Deployment
1. Install the data I/O cable on the FastCAT end cap:
A. Lightly lubricate the inside of the cable connector with silicone
grease (DC-4 or equivalent).
B. XSG Connector - Install the cable connector, aligning the raised
bump on the side of the cable connector with the large pin (pin 1 -
ground) on the FastCAT. Remove any trapped air by burping or
gently squeezing the connector near the top and moving your fingers
toward the end cap. OR
MCBH Connector – Install the cable connector, aligning the pins.
C. Place the locking sleeve over the cable connector and tighten it finger
tight only. Do not overtighten the locking sleeve and do not use a
wrench or pliers.
2. Connect the I/O cable to the computer/controller.
3. Connect the I/O cable connector’s red (+) and black (-) wires to a power
supply (9-24 VDC).
4. Verify that the hardware and external fittings are secure.
5. If plugs were placed on the end of the T-C Duct and exhaust fitting to
keep dust, debris, etc. out of the conductivity cell during storage,
remove the plugs.
6. Immediately prior to deployment, apply power and start sampling:
• If AutoRun=Y, applying power started FastCAT sampling.
• If AutoRun=N, send Start (in Seaterm).

CAUTIONS:
• Do not use WD-40 or other
petroleum-based lubricants, as
they will damage the connectors.
• For wet-pluggable MCBH
connectors: Silicone lubricants
in a spray can may contain
ketones, esters, ethers, alcohols,
or glycols in their propellant. Do
not use these sprays, as they
will damage the connector.
