Remotely operated underwater vehicle GNOM is intended for inspection of underwater wrecks
and other objects by video camera.
The modern computer and telecommunication technologies are used in the device, and made it
easy in handling, compact, light and inexpensive.
These solutions allowed to use thin (only 6 mm diameter) and flexible communication cable for
transmission data, power and video signals to/from vehicle. The special Kevlar threads have been
used to improve the cable's tensile strength. Because of this fact, the device keeps the highest
degree of stabilization what is very important for inspections. The vehicle has a good
maneuverability and can easily turn on the spot.
High-effective electric motors with magnetic couplings and hi-tech electronics are used in the
vehicle, provide the fast speed of the GNOM with low power consumption.
One of the most important features of this device is a possibility to operate it from PC and via
Lan/Internet.
The GNOM, in essence, an underwater helicopter with the video-camera which moves in any
direction according to the operator's instructions.

1. DESCRIPTION
Thrusters are DC motors which are put into the aluminium halls . The rotation transmision to
the screw propeller is realized with aid of magnetic coupling disks.
One disk is fastened at the motor's shaft in the body, and the other one – at the screw
propeller's shaft inside the cone-shaped head , which is filled up with water. The cone-
shaped head may be removed by operator for cleaning ( see manual).
The vehicle is connected with the operators console via thin cable, which transmits power
voltage, operation instructions, data and video signal from the vehicle.
The cable with diameter 6mm is stregthened by Kevlar threads (breaking effort is 90kg) and by
additional polyehylene shield. The cable length is max up to 250m. To compensate the weight of
vehicle and give neutral buoyancy to it, the float made of foam polysyren is used, and it is put
in front part of vehicle. Similar floats can be put on the cable to change the neutral buoyancy to
little positive buoyancy. Maximum operating depth of vehicle is 200m.
Using the control pads and joystick the operator can move GNOM forward-backward, turn to the right – left, up – down; adjust the thruster speed and the lights brightness. All data is displayed on the monitor in "TV-text" mode. By pressing one of the buttons on the joystick the operator can pass to the menu of tuning up some vehicle's functions – calibrating of the depth sensor and the compass as well as some other functions.
Control Panel "Sony PS" is connected to the control and power module installed in a
waterproof case in which also 15 "monitor is built. The power supply operates from 100 to
230 VAC or 12 VDC.

2. USER’S MANUAL FOR OPERATION
2.1 Deployment
1. Before using, please, check up all parts of vehicle especially propellers, cable and dome. Clean it if it is necessary. Check propellers rotation by finger.
2. Plug in 3-sockets connector to reel, power and video cables to monitor.
At use of the built in monitor before its connection it is necessary to weaken a clamp! Also AC power cable (if you work from 100-230VAC).
Do not rotate thrusters on air!
Do not switch lights on a full power on air!
Be very careful with cable, do not:
- stand on it
- press it
- twist it.
voltage on a cable is 180VDC! If any damages happen you must repair or change the cable.
2.1.1 - You can not connect to the GNOM and other devices (accessory) to the mains
with the following problems:
• Wrong - incorrect wire connections L and N conductors in the appropriate slot.
• without protective earthing conductor.
Note. Checking the correct wiring connections (phase conductor - L) inspects the
operator. (E.g. by phase tester)

2. USER’S MANUAL FOR OPERATION
2.1.2 Checking the RCD
Carry out before any underwater operation at the new location as follows:
• If the requirements of paragraph 2.1.1 are met and connect to the power supply only
power module
• Switch on mains voltage button on the control panel
• After 5 seconds press the "TEST" button on the residual current device. It would
immediately lead to a safe shutdown of module
• Switch off the mains voltage button on the control panel. Switch on the current
circuit breaker
• Again switch on the power supply button on the control panel. Residual current
device must remain switched on.
Set switch 230V ON (UP position).
3. After power ON you see message WELCOME. GNOM is ready for operation.
If you use GNOM in a sea than should do GNOM heavier. For that you need to
open plastic pipes which are under the GNOM and fit pieces of metal (the best is
lead).

Special Functions
Sleeping mode (Power Saving Mode)
In order to save power and lengthen the using life of batteries, a power saving system is designed in
the wireless joystick. The joystick turns into sleeping mode (power saving mode) under the
following conditions:
A. If there is no operation within 30 seconds since the connection between the controller and the
receiver, the controller will turn into sleeping mode (power saving mode).
B. There is operation since the connection between the controller and receiver. If there is no
operation for 5 minutes, the controller will turn into sleeping mode (power saving mode).
Press【 or or 】button can stop this sleeping mode
(power saving mode).

7. MAITENANCE OPERATION To maintain the vehicle it is necessary:
to clean the propellers from alge, sand and mud to rinse the vehicle in the fresh water after using in the sea to inspect the cable after the operation. In case of any damages the cable must be
repaired or changed to check the magnetic disk coupling regularly Use silicon oil spray for lubrication shafts of props every time after diving. Oil must
penetrate inside of conus heads of motors. See appendix position 96, 147, 217 of thrusters assembly.
Avoid nods and twisting of cable.
Within the certificate of warranty the bond (joint) mainenance manual is included. Use it only in case of emergency, if standard maintenance is insufficient. Before this service consult technical problems in our company on email addresses:
[email protected] or [email protected] Attention: In case of non-professional action and damage of any part, the consecutive service in our company will be charged.

8. SAFETY REQUIREMENT
1. Device belongs to CLASS 1 . For this reason the power adapter must have connection to protective earth.
2. Swith-on and swith-off the machine by main 230V switch, which is placed over the power cord to the external control unit.
3. Do not use the system with the damaged cable. 4. Do not touch underwater vehicle and the cable if you are in water and the power is
turned ON. 5. Keep the control module and the cable reel dry. 6. When recharging the battery disconnect the vehicle and the cable reel.
