Unit overview
The FU Amplifier Proportional AS for proportional rudder control is the central component of the rudder control system. It controls the hydraulic valves of the steering gear until the rudder actual value has reached the set value of the rudder.
The FU Amplifier Proportional AS operates as a constant regulator, i.e., the hydraulic valves are opened less as the control deviation decreases and the rudder movement speed is reduced.
The FU Amplifier Proportional AS controls3-phase DC motors, torque motors or proportional valves. As set rudder input FU-tillers, NFU tillers or autopilots can be used. In addition a NFU operation via push buttons on the FU-Amplifier Proportional
AS itself is possible.

3 Operation
3.1
G eneral
The FU Amplifier Proportional AS is operated from the bridge in normal operation
(operation mode BRIDGE). Operation mode LOCAL is only used for servicing work or emergencies.
The current operating mode is indicated at the bridge.
3.2
S witching on
The FU Amplifier Proportional AS does not have its own ON/OFF switch. There are two options available to switch the unit on, and these must be determined during the planning stage:
1. Switching on the status contact “Pump ON”:
The FU Amplifier Proportional AS is supplied by the same power supply as the steering gear. The FU Amplifier Proportional AS is then activated by the status signal
“Pump ON”.
2. Switching on via the mains power supply:
Contact “Pump ON” is jumpered in the unit, and thus the FU Amplifier Proportional AS is switched on when the power supply is switched on (via the pump selector switch).

Notes / Comments
Modes of operation:
1) Steering mode selector switch ‘NFU Direct’ means:
Steering control by the main
NFU-Tiller
2) Steering mode selector switch ‘Main’ means:
Stering control by the activated CAN Bus unit
(Handwheel, Autopilot, or
Tiller).

LOCAL: The steering gear is controlled from the steering gear compartment.
BRIDGE: The steering gear is controlled from the bridge.
Note:
The operation mode of the FU Amplifier Proportional AS is indicated at the alarm panel (e.g. NAUTOALARM unit) via potential-free contacts. This status is also distributed via the CAN-Bus and can be displayed by means of an Alarm Signal unit
AS, type 135-111 alternatively
Operation mode E ME R G E NC Y
If the steering gear is provided with an emergency switch, it is possible to deactivate the FU Amplifier Proportional AS by use of the switch.
S witching off
The FU Amplifier Proportional AS does not have its own ON/OFF switch. It is automatically switched off when the associated pump of the steering gear is switched off.

•
The overcurrent
