2PRODUCT DESCRIPTION
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 contains an elegant polished chrome jog handle and black surface
finish complements vessel control stations. Optionally, the 7171 can be configured to contain
a small wheel in place of the jog handle.

4COMMISSIONING
4.1 ELECTRICAL CHECK
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.
4.2 FUNCTIONAL TEST
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.

5OPERATION
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.
Figure 5: 7171 Positions of Operation, SWITCH LEFT, FFU LEFT, CENTRE, FFU RIGHT and
SWTICH RIGHT
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.
