The Non Follow Up Lever Unit is immediately activated (ready) when the Steering Mode Selector Switch is set to “NFU”. The “ACTIVE” condition is confirmed by the status LED on the NFU Lever Unit Control Panel.

Operation of the sprung to centre NFU Lever to Port or Stbd results in rudder application in the appropriate direction. When the lever is released back to centre, rudder application will stop and the rudder will be stationary at whatever angle existed at the instant of NFU Lever release.

Further movements of the NFU Lever will produce corresponding rudder movements and prolonged NFU deflection will move the rudder hard over.

Typically, the NFU electrical connections are routed as directly as possible to the rudder system via the Steering Amplifier (bypassing the Steering Controller).

Where more than one NFU Lever Unit is required, these can be installed on a modified software basis which uses the “Auxiliary” input(s) of the Steering Controller via the Steering Mode (“AUX”) Selector Switch.

The NT1001 NFU can be included in the standard Navitron Steering Console or desk control panel and/or remotely in wheelhouse/protected bridge wing locations.
