CHAPTER 5
Maintenance
5.1
General
As typical deployment depth of the RDCP 600 is between 5 and 50 meters, fouling will occur,
especially at low latitudes. The use of anti-fouling paint must be considered based on your own
experience.
The complete firmware in the RDCP 600 may be upgraded be means of the MMC slot.
NOTE!
Always leave the Transducer Head uncoated.
Do not use any form of steel brush or any sharp objects on the Transducer Head, as this will
damage the acoustic elements.
5.1.1
Yearly Maintenance
The procedure below indicates the minimum maintenance that must be carried out each year or
every time the RDCP 600 has been retrieved, two to four times a year for fixed installations
depending on the environmental conditions, and every 3 years for factory service:
1.
Remove marine growth and barnacles from the sensor(s) using a hand scrub. To remove
sea shells or corals use plastic handle or similar tools.
2.
When inspecting, look for corrosion on connector’s cracks on the back potting of
connectors and scratches on protecting cable(s) jacket.
3.
Rinse the exterior of the instrument in fresh water and let dry.
4.
Clean the transducer head.
5.
Open the instrument and check for leakage through the transducer head or in the pressure
case.
If leakage, locate the source of the leakage and correct for it.
6.
Replace the zinc anodes and corroded parts as necessary.
7.
Remove the O-rings.
8.
Make sure that the O-ring seatings have a clean and smooth surface.
9.
Lubricate the O-rings with silicon grease.
10.
Replace the O-rings and pressure inlet.
11.
If the transducer head has been disconnected, replace the silica gel bags.
12.
Always install new O-rings on plugs that have been disconnected.
13.
Check for deformation of the C-clamps. Replace if necessary.
14.
Always apply TECTYL®
on screws before installation to avoid crevice corrosion. Add
also TECTYL® around sensors and sealing plugs.
15.
Check for scars on the EPOXY coating, the Top end plate and the frame.
