PRODUCT DESCRIPTION

KOBELT-7171-Full-Follow-Up-FFU-Control-Lever-fig-1

The Kobelt 7171 Full Follow Up (FFU) Control Lever is used as an input to FFU electronic steering systems. The operator can maneuver the vessel by moving the lever port or starboard to adjust its internal potentiometer. The FFU Control Lever can be used for steering applications, other marine applications, or industrial installations.

The 7171 can be purchased with electrical switches at the far port and starboard extremes to handle Non-Follow Up (NFU) mode command signals to the on-board control system. The 7171 is designed for indoor and outdoor installation with a robust die cast bronze and stainless steel construction to provide a long service life in a harsh marine environment. The standard configuration includes a polished chrome jog handle and black surface finish. Optionally, the 7171 can be configured to use a small wheel in place of the jog handle.

ELECTRICAL SWITCH CONTACTS	—

(per direction)

***** Requirements to achieve IP56: Minimum 3/16” [5mm] thick steel dash, or equivalent. Requires 4x installation screws to be sealed. IP rating only applies to units manufactured after March 2022

INSTALLATION

MECHANICAL

In a central location at each station on-board the vessel
With sufficient room for the handle to swing fully to both extreme conditions
Within 6 feet [1.8 m] of electrical junction box
On a horizontal or angled dash surface
With the external electrical cables protected from potential damage

The FFU lever must be mounted on a flat surface with a maximum roughness of ra = 125 micro-inches [500 m]. The mounting surface must have the following minimum thickness to prevent excessive flexing:

Steel consoles: 0.19 inches [4.8 mm]
Aluminum consoles: 0.27 inches [6.8 mm]

The FFU Lever is equipped with (4) four mounting holes for #10 [M5]. Use #10 or M5 sealing screws or bonded sealing washers to prevent water ingress below the dash. Tighten the fasteners to 23 in-lbs [4 Nm] with an anaerobic thread locker such as Loctite 243.

ELECTRICAL

The FFU Control Lever has 6 foot [1.8 m] long 3C/18 cables for external connections. Connect them to an electrical junction box and the electronic or power hydraulic steering system interface as required. The product’s 3C/18 electrical cables contains the following wires and related functions:

COMMISSIONING

ELECTRICAL CHECK

Caution: Ensure that the rear cover is installed and secured before powering on the 7171.

Confirm that the electrical connections to the 7171 have been made correctly and correspond to the requirements of your system installation.

FUNCTIONAL TEST

Caution: The Functional Test should be carried out while the vessel is still at dock and before it is taken out to sea after installation has been completed.

A complete functional test should be performed on the system that the Full Follow Up Control Lever has been installed within before entering operational use.

OPERATION

KOBELT-7171-Full-Follow-Up-FFU-Control-Lever-fig-5

The Kobelt 7171 Full Follow Up (FFU) Control Lever contains one or two potentiometers and optionally a set of switches for each direction of travel. Operating the FFU Control Lever causes the steering gear to move in the desired direction. When the lever is released it stays at the set position and does not spring back to centre. Operating the lever in either Port and Starboard, or Left and Right, directions commands motion in the system it is controlling.

Caution

Ensure that the FFU Jog Lever is set to within a few degrees of the current rudder angle before switching into FFU mode.
Not doing so will result in immediate movement of the rudder to the commanded position.

MAINTENANCE

PREVENTATIVE MAINTENANCE

Quarterly (4 times per year)
- Visually inspect wire and cable insulation for splits or damage.
- Ensure there is no visible corrosion on the unit.
- Conform cable glands are secured to cables.
