1.2 Power Requirements
The LBV system is designed to operate from common power sources. When establishing
the correct power source for the LBV, be sure to consider what other equipment might be
used at the same time to avoid erratic power supply to the LBV.
CAUTION: Do not plug an Integrated Control Console or Surface Power Supply
configured to 100-130 VAC into 200-250 VAC power source and vice versa. This
will damage the LBV system and may cause physical harm.
CAUTION: When using a generator or inverter to supply power to the LBV, you
must provide a path from this device to earth ground. Usually, a generator will have
a large, threaded post marked with a symbol. This post should be electrically
connected to the water in which your LBV will be deployed. Also ensure that the AC outlets
of the device are grounded to this point. Always refer to your device‟s manual for proper
grounding instructions.
Failure to properly ground the LBV system may potentially disable the LBV‟s ground
fault interrupt circuitry and expose you and others to dangerous or lethal voltages!
Other undesired operation and consequences may also result from the improper grounding
of the LBV system.
Both the Surface Power Supply and the Integrated Control Console can be configured
internally to accept either 100-130 VAC or 200-250 VAC. Please refer to our website for this
procedure.
http://www.seabotix.com/support/procedures/2_19_voltage/Voltage_change.pdf
LBV systems fitted with the HPDC1502 Brush-Less DC Thrusters have a requirement for
1,200 watts 100-130/200-250 VAC, 50/60 Hz.

1.3 Setting up the System
Select a suitable area from which the LBV will be deployed and controlled. The area should
be dry and not in direct sunlight. Now the LBV is ready to set up.
The first step is to connect the tether to the LBV. Prior to connecting, ensure that the
Integrated Control Console/Surface Power Supply is OFF.
1.3.1 LBV
Step 1
Position the LBV so you that you can see the rear of the LBV. Located at the upper
right next to the flotation is an 8-contact male connector.
Step 2
Put a small amount of silicone grease on your finger. This is GLA001 which is
supplied with your order.
Step 3
Apply a small amount of the grease to the male pins on the bulkhead connector.
The grease is simply for lubrication and not a sealant.
Step 4
Locate the tether female connector and the strain relief.
Step 5
Open the shackle completely. Note: There is an indent to allow the locking rod to be
flush with the “D”portion of the shackle.

DOCS-010 Manual, SeaBotix Inc. Users, 200 Series –18 Mar 09 - Rev B - Page 10 of 52
Step 6
Slide the shackle over the pad eye beneath the flotation module. Twist the locking
rod to secure.
Step 7
Push the female connector onto the male bulkhead connector being careful to align
the pins. On the 3-contact connectors there is a single small pin used for alignment.
Step 8
Tighten the locking ring clockwise. Do not over tighten.
Once the tether is connected to the LBV, the next step is to connect the Integrated Control
Console/Surface Power Supply. Again, ensure that the Integrated Control Console/Surface
Power Supply is OFF.

DOCS-010 Manual, SeaBotix Inc. Users, 200 Series –18 Mar 09 - Rev B - Page 16 of 52
1.7 Trimming ROV
The LBV is designed to be NEUTRALLY buoyant and when placed in water should maintain
its depth without rapidly surfacing or sinking. From the factory, the LBV comes trimmed for
fresh water, unless otherwise specified by the client. The use of the LBV in salt water or
alteration of the LBV hardware will affect buoyancy. Should your LBV require buoyancy
adjustment follow, the procedure below.
Refer to the Manufacturing Safety Data Sheets (MSDS) for working with lead.
NOTE: If the LBV is positively buoyant or negatively buoyant, the vertical thruster
not be as effective, and the auto depth function may not work at all.
If trimmed for fresh water, the addition of 2.5 full strips of lead supplied in the basic spares
kit, (BSK) will usually adjust the trim sufficient for operation in salt water. Brackish water will
require slightly less lead depending on salt levels. However; every LBV has slightly different
ballasting characteristics. The operator may need to add, move or subtract weights on the
LBV for the desired operation in various bodies of water.
Step 1
Make sure that the tether is connected correctly as this will
affect the buoyancy of the LBV.
Step 2
Place the LBV in the same type of water in which it will be
operated, i.e. fresh, salt or brackish water. While holding
the handle or bumper frame, turn the LBV upside down
and agitate it to release trapped air.
Step 3
Place the lead weight strip found in the basic spares kit
(BSK) on the bumper frame to achieve the desired
buoyancy. You may have to the cut strips to fine adjust
the trim. Make sure that the LBV is level left to right and
fore to aft.
Step 4
Once the LBV is neutral, straighten the lead strips and
attach to the lower portion of the bumper frame using
M5x10 button head screws provided in the BSK. Be sure
to place in the same relative position to ensure that the
LBV is properly set up left to right and fore to aft.

DOCS-010 Manual, SeaBotix Inc. Users, 200 Series –18 Mar 09 - Rev B - Page 17 of 52
1.8 Calibrating Compass
The LBV is fitted with a magnetic compass that is designed to provide basic heading data. It
should be noted that the sensor is fixed inside the LBV and therefore is susceptible to
varying environmental conditions. If the LBV is pitching up and down, the sensor will lose
accuracy. To ensure that the heading sensor provides the most accurate data, proper
calibration is critical.
Place the LBV either on a flat smooth stable surface or in still water. It is important that,
during calibration, the LBV does not pitch up or down. Remain clear of ferrous materials
and high power electronics such as transformers as they will affect the calibration. Access
the calibration menu as follows:
Press PGRM
Press 5 (Main Menu)
Press 2 (Calibrate)
Press 4 (Compass)
The on screen display will prompt that you “Rotate the LBV 360º and press Enter”. The key
to the calibration is that the LBV is rotated as slowly as possible. Essentially you want to
have the LBV pointed in all 360 degree increments. This may take several minutes but
ensures the most accurate reading. The slower the LBV rotates (and the greater the
amount of rotations) the more accurate the compass will be. Once complete:
Press ENT
Press PGRM.
NOTE: This calibration is required initially and is then stored into memory. However, should
the LBV be used in a different geographic location, re-calibration may be required. It is good
practice to calibrate the compass prior to each deployment.
Section 2. LBV Controls
The LBV has been designed to be simple and intuitive to operate. A new user should find
that after reading this manual and an hour or so of hands on use, operating the LBV is quite
easy. Using the tips in this manual will help you to become a proficient and confident LBV
operator.
2.1 Operator Control Unit (OCU)
Operation of the LBV is done through the Operator Control Unit (OCU). This section will
help to explain the use of each key and when each should be used. When first learning to
operate the LBV, spend time with the LBV at the surface where you can see how the
commands affect the LBV.

DOCS-010 Manual, SeaBotix Inc. Users, 200 Series –18 Mar 09 - Rev B - Page 18 of 52
Holding the OCU correctly will help. The recommended method is to hold the OCU in both
hands with the left hand using all fingers to support the console and the thumb resting on
the vertical thruster knob. Place the right hand in such a way that the forefinger and thumb
hold the top of the joystick and the other three fingers support the console. Some may
prefer to place the console on a flat surface.
2.1.1 Joystick
The joystick is a proportional control, allowing the operator to operate the thrust as little or
as much as desired in any horizontal direction. Pushing the joystick forward moves the LBV
in the forward direction. Pulling the joystick backwards moves the LBV in the reverse
direction. Moving the joystick laterally moves the LBV in the respective direction laterally.
Rotating the upper portion of the joystick rotates the LBV clockwise or counter clockwise.
2.1.2 Proportional Vertical Thruster Control Knob
Located on the left side of the OCU is the vertical thruster control knob. Positioning your left
thumb on the top of the knob will allow you to easily rotate the knob. Rotating the knob
forward causes the LBV to surface and, conversely, rotating the knob backward causes the
LBV to dive. This function can be reversed in the Options menu on LBVs with flash memory
of ROV3.02 or higher.
The control knob is variable and has a center detent turning the vertical thruster off. Ensure
that the vertical thruster is off prior to removing the LBV from the water.
2.1.3 Camera Control
Note: Tilt, focus and internal light controls are not enabled when a rear facing camera is in
use on LBV‟s so equipped.
2.1.3.1 Camera
The CAMERA button allows the user to select between two cameras if fitted to the
LBV. When the CAMERA button is pressed, the image on the monitor will switch
to the other camera and the camera chassis will rotate 90 degrees to provide the
same viewing angle if “camera rotate” is on (section 2.3.6.1). Also, switching
cameras switches the focus controls for the viewing camera. If a light accompanies the
optional second camera, the light controls will also switch.

DOCS-010 Manual, SeaBotix Inc. Users, 200 Series –18 Mar 09 - Rev B - Page 19 of 52
2.1.3.2 Tilt
The TILT buttons allow the user to rotate the camera chassis up or down.
The maximum rotation is 180 degrees per camera giving a total of 270
degrees if an optional second camera is fitted. As the camera chassis
rotates, the angle is displayed on the Video Overlay.
Note: In the Options menu the keys can be reversed for desired preference.
(section 2.3.6.)
