Should an X2-CB or iSIC-CB need to be sent in for evaluation or repair, please reference the following steps for removal:
Tools Required– 9/16″ Socket Wrench
1. Disconnect the 6-pin solar panel cable from the X2/iSIC-CB SOLAR port to remove power from the data logger.
2. [For CB-150, 450 buoys only] Remove the buoy’s solar tower to gain access to the data well.
- Remove the (6) 3/8-16×3/4 bolts and 3/8 lock washers holding the solar tower to the buoy using a 9/16 socket wrench
3. Remove the (8) 3/8-16×3/4 bolts and 3/8 lock washers from the X2/iSIC-CB or data well pass-through plate using a 9/16 socket wrench, loosening them in a cross pattern.
4. Lift the X2/iSIC-CB plate off of the data well. Disconnect the 6-pin UW-plug running between the solar regulator and the iSIC-CB. This will expose the data well where the battery and solar regulator are installed.
5. Pack with plenty of protective material and ship the X2/iSIC-CB to:
NexSens Technology, Inc.
2091 Exchange Court
Fairborn, OH 45324
6. For deployed systems it will be necessary to protect the data well and system batteries while the logger is being evaluated. In most cases, NexSens will provide a blank plate to maintain a water-tight seal.
7. Inspect the large o-ring on top of the data well.
a. Clean any debris that may have accumulated on top
b. Inspect for any tears or abrasions on the o-ring surface, replacing if required.
c. Ensure the o-ring is well greased. Each buoy maintenance kit will have a tube of this for use.
8. Cap the loose 6-pin solar cable remaining in the data well if possible to keep it clean and dry.
9. It is recommended a new bag of desiccant be tossed into the data well at this time.
10. Install the blank plate.
a. Place the blank plate over top the data well and align the holes.
b. Re-install the (8) 3/8-16×3/4 bolts and 3/8 lock washers from the X2/iSIC-CB or data well pass-through plate using a 9/16 socket wrench, tightening them evenly in a cross pattern to ensure an even o-ring seal.
11. Ensure that all sensor port receptacles on the blank CB-plate are occupied with a hand-tightened dummy plug or a sensor cable plug from any of the deployed sensors. Additionally, verify each plug and receptacle have a clean O-ring.
