2.3 PRODUCT HAZARDS
Equipment Starts Automatically: The Kobelt Steering Controller valve outputs are
controlled remotely and/or through a control loop. They may be driven unintentionally
through improper closed loop feedback and or unintentional operator commands. Ensure
all power sources are disconnected or locked out prior to performing system maintenance
or repair.
Disconnect Power: Turn off power at distribution panel before beginning installation to
protect installer from electrical hazards.
Voltage and Power Compatibility: Confirm that the power and voltage requirements of
the system are compatible. Ensure that the voltage drops from cabling is within the
specifications of the product. If voltage drops are excessive the system could fail due to
low voltage conditions resulting in abnormal behavior and or loss of function.
Voltage and Current Compatibility: Confirm that the power source is compatible with the
maximum voltage and current ratings of is product variant. Failure to do so could result in
damage or fire.

4TERMINOLOGY AND DEFINITIONS
Before proceeding with the configuration and operation of the Kobelt Steering System, is it important for the user
to become familiar with the terminology and basic functions used throughout this manual.
4.1 STATIONS
Stations are physical locations around the vessel where controls are located. On each station with a Kobelt steering
station, there are one or more input device(s) (Steer-by-Wire Helm, Jog Levers, etc.).
Some common station locations include:
•the Main Bridge,
•the Fly Bridge,
•a bow or aft station,
•port or starboard wing stations,
•the Engine Room.

5KOBELT STEERING SYSTEM OVERVIEW
5.1 SYSTEM DESCRIPTION
The Kobelt Steering System is a configurable, electro-hydraulic steering control system for marine vessels. The
system is comprised of a minimum of one steering Controller and one to four steering stations. The system is
interconnected by the KNet network for communications and power. The Kobelt Steering System controls one or
two hydraulic solenoid steering outputs for a single rudder, or two independent rudders. The valve outputs may be
configured as on-off, or proportional control. A Steering Station can interface any combination of one NFU, one
FFU, and one SBW Wheel control input. Commands are accepted at the steering station in control and transmitted
digitally to the steering controller to act upon. The steering controller takes the command and controls the
steering gear for the desired operation. A RFU is used by the controller to determine the angle of the rudder and
continually positions the desired order for full follow up operations. Non-follow up commands are acted upon
without the benefit of the rudder angle in single rudder applications. Additionally, an integrated autopilot interface
that takes control signals from a traditional autopilot to control the valves for the desired autopilot operation.

the station select button on the station.

Kobelt Steering System Kobelt Manufacturing Co. Ltd.
rev A MNL-002.docx 17 of 126
▪Automatic transfer allows a jog or wheel command to transfer to a given station.
▪Optionally, use the station lock feature to prevent other stations from taking control.
oIncludes an LED-strip-style rudder angle indicator and rudder order indicator on the front panel.
•KNet Network Communications
oBased on, but not compatible with, the NMEA 2000 standard. KNet uses a proprietary protocol
handles the communication and power distribution for the system.
The System is not NMEA 2000 compatible and needs to be isolated from any onboard
NMEA 2000 network.
5.3 CONTROLLER
5.3.1 Feature Overview
•Configurable to meet the needs of numerous installations.
•Diagnostic features to aid in problem solving.
•Up to 4 stations supported.

5.4 STEERING STATION
The steering station is the operator interface to the steering gear. The steering station takes operator control
inputs and relays them to the steering controller to drive the steering gear. Steering stations should be installed at
the main and auxiliary helm points.
5.4.1 Feature Overview
•Controls for selecting different control methods.
•Integrated Jog Controls
•External Jog Connector for one speed or 2 speed jog devices

6INSTALLATION
6.1 LOCATION REQUIREMENTS
The location of the controller unit should be within 10m(32.7 ft) to the solenoid valves to reduce voltage drop. If a
voltage RFU is used, the location of the controller should be within 18m(58.87ft) of the RFU to reduce electrical
noise induced on the signal wires. 4-20mA RFUs’ are less susceptible to noise.
Station 1 can override station lock at another station. It is recommended that this station
should be in the main bridge or the machine room depending on emergency procedures.
6.2 MECHANICAL
The Controller needs to be installed in an IP44 enclosure(minimum) for machinery rooms, or IP56 enclosure in
exposed locations.
The controller is rail mounted on 35mm DIN rail.
The steering station is rated IP56 and can be mounted to any flat console or dashboard.
The mounting surface must be prepared as per the
diagram at right (Refer to Appendix B: Station Cutout
Template ). Secure the panel with the four #8 UNC
studs supplied. Apply Loctite 243 and tighten using a
11/32” wrench.
6.3 ADDITIONAL COMPONENTS
The controller and stations are supplied with standard 5 pin –M12 connectors. It is a system design decision for
the cabling. It is possible to use Mini sized wiring with Mini to Micro/Mid reducers at the devices. This will allow a
better power distribution.
Standard Micro/Mid connectors are specified for smaller wire gauge than is specified for the backbone cable.
Running larger gauge wire will reduce total impedance. This is an important consideration when running backbone
cables.

It is required that each system is designed with the ability to override the control system
with a local backup. This can be accomplished by switching out the control system valve
output with an NFU jog connected directly to the solenoid giving manual control over the
valves.
Redundant power for the steering system is recommended.
For resilient systems a redundant KNet cabling is recommended in case of cable damage
that may occur.
6.4 COMPASS SAFE DISTANCE
The compass safe distance for the steering station is tested to be 1.5cm.
6.5 EMC INSTALLATION GUIDELINES
6.5.1 Suppression Ferrites
Kobelt cables may be pre-fitted or supplied with Electromagnetic compliance ferrites. These ferrites are important
for the system to meet EMC performance requirements. If ferrites are supplied separately, you must fit the
supplied ferrites to the correct cables as listed in the instructions.
If the ferrite is removed for any purpose (Installation and or maintenance), it must be replaced to the correct
position before the product is used. If the ferrite is damaged or lost a replacement needs to be installed of the
correct value from Kobelt or an authorized dealer.
6.5.2 Shielded cable and grounding methods
Shielded cables shall be utilized when connecting to the Kobelt Steering Controller and steering head. The shield of
the cables shall be grounded at the controller.to ensure proper EMC compliance, the connected to the bonding of
the ship.
6.5.3 Ferrite Locations
6.5.3.1 KNET Power Connector
One of the supplied ferrites must be attached to the power tee connector as shown in Figure 4: KNET Ferrite
Choke. The power and ground must be looped through the ferrite clamp two times.
