Intended use of the equipment Note: Use the unit only in the way described in this manual. Failure to follow the guidelines and instructions in this manual may be dangerous and result in damage to the equipment and erroneous measurements. FiGS 2.0 usage FiGS 2.0 is a sensor for measurement of cathodic protection activity and corrosion for assets in seawater, such as pipelines, subsea structures and fixed installations. The sensor is mounted on an underwater vehicle, such as a ROV, AUV or ROTV.
The sensor consists of 3 main parts: o o o Rotor Motor housing Electronics housing The sensor is built up with 3 sensing electrodes mounted on a rotating shaft. The rotating part, from now on called the rotor, will rotate at a speed of 250 or 500RPM when the sensor is in operation. The motor and part of the rotor is enclosed in the motor housing, which is oil filled and pressure compensated.

Equipment installation Connect FiGS 2.0 sensor to the FiGS 2.0 power bottle with the supplied cable. Check that the power bottle is mounted the correct way. The power bottle is marked with “FiGS side” and “ROV side” on the bottle. If the power bottle is mounted the wrong way, the sensor will fail to power up. Make sure the receptible is clean and that the O-rings are clean and un-damaged. The O-rings shall be coated with a thin film of siliconebased O-ring lube.

The sensor can be controlled by a terminal software, such as Putty, or by a specific logging and control software. Protocol FiGS 2.0 FiGS can communicate over RS-232 at 19200, 115800 and 1000000 baud. The communication is ASCI based, i.e.
messages easier to read in a terminal window. NB! (\n) cannot be used as a terminal character when reading from the serial port. Non-formatted messages In addition to the formatted messages, FiGS also prints loose text. This is intended to be read by humans and should not be parsed by a computer.

MAINTENANCE Cleaning After every use. To clean the sensor, perform the following steps: 1. Keep the cables connected to the receptables or us a dummy-connector to keep the receptable pins dry. Clean the sensor in cold freshwater. Use a hose to hose off any seawater and salt remnants. Dry off with paper towels or leave to dry. 2. Remove electrode caps and carefully remove the cotton plugs. Rinse with clean fresh water. Electrode cap 3.
Sensor head Electrode 4. For special cleaning, skip part 3 and place the sensor head in an ultrasonic bath with isopropyl alcohol for 2 minutes. Leave to dry and mount new cotton plugs and remount the electrode caps. 5. Cleaning of receptables: remove connector and O-rings and clean the receptable with a soft cloth soaked in isopropyl alcohol. 6. Wipe off O-rings, check for damage, replace if necessary, add O-ring grease and mount O-rings on receptable.
o Oil-fill plug on motor housing Oil-fill plug o Oil-fill plug on penetrator Oil-fill plug o Around oil-filled hose
Oil filled hose o Between motor housing and electronics housing Check for oil 2. Check for damage to cables and connectors. Any damaged cable must be replaced. Failure to replace damaged cables can result in damage to the sensor and loss of function of the sensor. Contact FTN for replacement cables. 3. Check that no bolts are loose. M3 bolts shall be tightened to 1.8Nm and M4 bolts shall be tightened to 4.3Nm in the lid and 3.5Nm to the motor housing.
Warning! Do not replace bolts! The bolts are made specifically for this sensor. Replacement of bolts made from other materials and /or other specifications may lead to water ingress and erroneous measurements. Replacement bolts can be obtained from FTN. Note: If any leakage is found, contact FTN for service. Unrepaired leakages will result in loss of oil and possibly loss of function of the sensor. Note: Do not attempt to refill hydraulic oil without proper tools. Filling tool MK2 TSAS, Part No.
Label / Marking for model identification The sensor and power bottle are marked with the following tags and symbols.
