2PRODUCT DESCRIPTION
The 7180 Rudder Angle Indicator is a smaller version of the popular Kobelt 7175 Rudder Angle
Indicator. The 7180 is available in Master and Slave configurations in both 12 VDC and 24 VDC
offerings. Both the Master and Slave contain a backlight to illuminate the indicator during
dark operating hours.
The 7180 Rudder Angle Indicators will provide you with real-time visual display of the position
of your rudder while your vessel is underway. Whether you are manoeuvring, or your
autopilot is commanding your vessels, an accurate readout of your rudder position will be
displayed on this tri-colour two-inch diameter display indicator.
The unit indicates the PORT direction of travel in Red and the STBD direction of travel in
Green for easy and quick identification while steering. The system supports one Master
Indicator with up to a maximum of 5 Slave Indicators (or “repeater stations”) commanded by
a single input signal. The indicators are driven by a position transducer such as the Kobelt
7163, 7168, or 7174 Rudder Feedback Units (RFU).

3OPERATION
The 7180 Rudder Angle Indicator system requires no direct user input to function. The system
is passive and responds to signals from a Rudder Feedback Unit or alternative signal sources
such as control levers. The signal commands the needle position on the Indicator. This
position can be calibrated to correspond to physical rudder position or the position of an
alternative signal source.
A single master unit can drive up to 5 slave units. The slave units directly follow the meter
movement of the master. Span configuration is done on the master unit. Zero adjustment is
available on both the master and slave units.
If a backlight dimmer is installed in the system, the operating instructions of the dimmer
manufacturer/installer shall be followed for adjustment of the dimmer.

4INSTALLATION
4.1 MECHANICAL
All meter variants contain the same physical properties and dimensions. The gauge meters
are to be installed using a 2.1” round hole in the desired panel or dash location on the vessel
(refer to Appendix B: Installation Cut-Out Template, for a mounting template).
Figure 2: Mechanical Dimensions
Ensure proper clearance is provided behind the panel or dash
installation location to allow for securing the tightening clamps to
hold the unit securely.
4.1.1 Mounting
A pre-installed bracket and fasteners are included with 7180 gauges for mounting the units.
1. Loosen and remove nuts holding brace to unit.
2. Remove brace completely from unit.
3. Insert unit into cut-out hole in the mounting location.
4. Replace the brace on the back-side of the unit.
5. Replace the nuts and tighten to secure the unit to the mounting location.
Ensure that the terminals are properly isolated, by the isolating
washers that separate the terminals from the mounting brace,
before powering on the unit.

7180 Rudder Angle Indicator Kobelt Manufacturing Co. Ltd.
Rev B MNL_7180 10 of 24
4.2 ELECTRICAL
The 7180 gauges support a nominal supply voltage of either 12VDC or 24VDC. The supply
voltage to the meter is isolated from the supply voltage used for the illumination. This
isolation allows the illumination to be powered from a separate power source or connected
to a common dimming control circuit for all dash mounted instruments.
The unit contains a T3-1/4 Miniature Wedge Base incandescent bulb holder with a 12 VDC or
24 VDC bulb pre-installed as per the model ordered.
A circuit breaker of 2A is recommended between the vessel power
supply source and the indicator(s) as shown in the example
installation diagrams.
All terminal wire connections to the meter should use crimped ring
or ferrule terminals, as appropriate, to ensure a secure connection
for high-vibration environments.
Control signals shown in the following figures are provided by standard control levers. Please
review the Kobelt website for all options available.
Electrical installation of the 7180 should proceed as follows:
Disconnect Power: Turn off power at distribution panel before
beginning installation to protect installer from electrical hazards.
Proper Electrical Polarity: Damage to the indicator can occur if input
voltage connection is reversed. Ensure proper connection of the
Positive and Negative terminals.
1. Connect electrical cables and power wires according to one of the configurations shown
in Figure 4 through Figure 6, and the additional details in this section of the manual.
a. Verify supply breaker (or fusing) is correctly sized as per specifications in
Table 1.
b. Verify wires and cables used are of the required gauge sizes and types as per
local marine regulations and standards.
2. Visually inspect all wiring to ensure correct installation.
Remove Shipping Clip: Remove protection clip used for shipping
found between terminal posts before applying power to unit.

5COMMISSIONING
5.1 ELECTRICAL CHECK
Ensure that the unit is properly installed and secured before
powering on the 7180.
•Confirm that all electrical connections to the 7180 have been made.
•Confirm that a breaker has been installed correctly and is turned ON.
5.2 CALIBRATION AND ADJUSTMENT
The gauge may need to be adjusted to centre the pointer when the rudder is centred and to
adjust the overall range of the meter to align with the position of the rudders maximum
travel.
Follow these instructions to configure the zero point and span using the on-board zeroing
lever and trimpot.
To reduce the potential for electrical shock and to avoid damaging
the 7180 electronics, use a non-conductive screwdriver, or other
equivalent tool, to adjust the trimpot or zeroing lever.
Exercise caution when reaching in with the screwdriver. Do not let it
touch any components other than the trimpots.
Ensure no oil, dust, or other contamination enters the 7180 while its
cover is removed.
1. Turn OFF power to the 7180 prior to making adjustment.
2. If adjusting the zeroing lever, remove the red plug or lightbulb, if installed.
3. Use a non-conductive flathead or Phillips-head screwdriver to adjust the trimpot
or zeroing lever.
a. Refer to the sections below for functional details of the trimpot and
zeroing lever
4. Turn ON power.
5. Move rudder through its range to verify desired response.
6. Repeat as necessary, until the 7180 functions as desired.
7. Replace the red plug or lightbulb, if installed.
Default position for the configuration trimpot is at centre (pointing upward).

Figure 7: Master Unit Calibration Trimpot Arrangement
5.2.1 Span Trimpot
The span trimpot adjusts the range of the meter when slave units are added in series.
Do not press down on the potentiometer as this can damage the
circuitry.
5.2.2 Zero Adjustment
The zero-adjustment lever is located inside the lightbulb cavity and can be accessed by
removing the red plug or the lightbulb, if installed. The zero point is adjusted by moving the
small lever inside the meter. Calibration of the zero point should be done when the rudder is
at dead-center.

7180 Rudder Angle Indicator Kobelt Manufacturing Co. Ltd.
Rev B MNL_7180 17 of 24
Zero adjustment should be done by qualified personnel only.
5.3 FUNCTIONAL TEST
Before commencing normal operations with the installed unit(s). A functional test be
conducted to ensure proper operation of the system as per the intended application and
configuration.
Functional testing should be done by qualified personnel only. The
system functionality should be fully tested dockside before an open
water sea trail is performed to ensure proper response of the
system based on rudder commands.
After installation perform the following function tests:
1. Center the rudder
a. Ensure that the meter displays 0°. If not, adjust the zero lever
until it is centered at 0°
2. Move the rudder to hard-over
a. Ensure that the meter displays the hard-over angle. If not, adjust
the ‘Span’ trimpot until it is at the correct angle.
