Section 6: Routine Maintenance
This section reviews underwater connector mating and maintenance, and
cleaning the SBE 33 Deck Unit.
Connector Mating and Maintenance
Clean and inspect connectors, cables, and dummy plugs before every cruise,
during a cruise (good practice if you have a few days of down time between
casts), after every cruise, and as part of your yearly equipment maintenance.
Inspect connectors that are unmated for signs of corrosion product around the
pins, and for cuts, nicks or other flaws that may compromise the seal.
When remating connectors for underwater portions of the system:
1.
Lightly lubricate the inside of the dummy plug / cable connector with
silicone grease (DC-4 or equivalent).
2.
XSG / AG 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 end cap. 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.
3.
Place the locking sleeve over the dummy plug / cable connector. Tighten
the locking sleeve finger tight only.
Do not overtighten the locking
sleeve and do not use a wrench or pliers.
Verify that a cable or dummy plug is installed for each connector on the
system before deployment.
Cleaning SBE 33 Deck Unit
To clean the SBE 33:
1.
Disconnect the power and any other cables from the back of the SBE 33.
2.
Using a soft cotton cloth dampened with warm water, clean the exterior of
the SBE 33 with gentle pressure. Use special care cleaning around any
connectors, to avoid getting water into them.
3.
Wait until the SBE 33 is completely dry before reconnecting power cables
and other electrical connections.
Note:

Application Note 57: Connector
Care and Cable Installation

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.
