SBE 9plus
Connector Mating and Maintenance
Note:
See Application Note 57: Connector
Care and Cable Installation.
Clean and inspect connectors, cables, and dummy plugs before every
deployment 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:
CAUTION:
Do not use WD-40 or other
petroleum-based lubricants, as they
will damage the connectors.
1.
Lightly lubricate the inside of the dummy plug/cable connector with
silicone grease (DC-4 or equivalent).
2.
Standard Connector - Install the plug/cable connector, aligning the
raised bump on the side of the plug/cable connector with the large pin
(pin 1 - ground) on the 9plus. Remove any trapped air by burping or
gently squeezing the plug/connector near the top and moving your fingers
toward the end cap. OR
MCBH Connector – Install the plug/cable connector, aligning the pins.
3.
Place the locking sleeve over the 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.
Plumbing Maintenance
For an SBE 9plus deployed in a vertical orientation A clogged air release valve can trap air, preventing the pump from
functioning properly; this will affect the data quality. Periodically clean the
air release valve:

1.
Use a 0.4 mm (0.016 inches) diameter wire (you can use #26 AWG wire)
to clean the valve. The easiest way to do this is to remove the Tygon
tubing above the air release valve, and use needle-nosed pliers to force the
wire through the hole.
2.
Blow through the air release valve to ensure it is open.
3.
(if applicable) Replace the Tygon tubing above the air release valve.
