DiveCAN Cable Maintenance Instructions
DiveCAN Five Pin Connectors Cable
The DiveCAN five pin connectors and the analogue four pin connectors are
durable and reliable so long as a few steps are taken to care for them. To
ensure the longest life and most reliable operation of DiveCAN connectors,
please observe the following maintenance advice.
The DiveCAN connector is intended to be a convenient way to separate
components should there be a need for service or repair. The connector is not
intended for frequent or routine disconnection. Leave the connectors mated in
use and when stored.
Do not mate the
DiveCAN connectors when wet. One of the pins is a power source and another is
a ground. Saltwater or fresh water with sufficient mineral content will create
an electrical path and the resulting chemistry will corrode the power pin
quickly. The four pin connectors do not carry the same voltage but should
still be cared for in the same manner.
If the DiveCAN connectors get wet with salt water, remove the battery from the
controller handset, rinse connector with fresh water, drain and dry, then
lubricate. Drying is best done with a jet of compressed air.
Please note that under no circumstances should the depth sensor of the
controller handset be dried with compressed air.
Lubricate DiveCAN connectors with a light coating of pure mineral oil or a
dielectric grease such as Molykote 111, or Electrolube CG60.
Always ensure the connectors are clear of debris before mating.
When mating and un-mating the connectors, use two hands, one grasping each
side of the connector. This is the best method for providing proper support
and alignment.
Ensure the mated connectors are fully engaged,
with minimal gap between each end.
Always use the correct strain
relief as recommended by the manufacturer of your Rebreather (see note on
strain relief types). This will reduce the chance of the DiveCAN connector
separating during use and suffering the corrosion described above.
There are three commonly used strain relief systems. A screw together style, a
sheath style, and a shroud.
- The style as used by Hollis is a screw together arrangement (see image below). This assembly should have hard plastic split rings rather than the soft rubber gaskets found on early versions. If yours has the soft gaskets, please contact you dealer to arrange for replacement. You can gently open the split ring to install on the cable.
The DiveCAN connector sheath/strain relief should always be installed and secured with O-rings, as pictured or by screwing the two halves together in the case of the rigid strain relief. The type of connector your Rebreather uses may vary depending on which is prescribed by the manufacturer of your Rebreather.
- The style used by rEvo is a plastic sheath secured in place with two rubber O-rings.
- This is the strain relief type used by JJ Rebreathers. This is screwed to the head of the rebreather using two screws and has a rigid plastic shroud which ensures the correct alignment and security of the connectors.
The screws only need to be tight enough to ensure the shroud is touching the
head and the screws are secure, there is no need to apply high torque to these
screws.
