1 Preface
1.1 About this Manual
This manual has been published primarily for professionals and qualified personnel.
The user of this material is assumed to have basic knowledge in marine systems, and must
be able to carry out related electrical work.
Work on the low-voltage circuit should only be carried out by qualified and
experienced personnel.
Installation or work on the shore power equipment must only be carried out by
electricians authorized to work with such installations.
1.2 Responsibilities
It is the sole responsibility of the installer to ensure that the installation work is
carried out in a satisfactory manner, that it is operationally in good order, that the
approved material and accessories are used and that the installation meets all
applicable rules and regulations.
Auto-Maskin continuously upgrades its products and reserves the right to make
changes and improvements without prior notice.
All information in this manual is based upon information at the time of printing. For updated
information, please contact your local distributor.
The crossed-out wheeled bin symbol indicates that the item should be
disposed of separately. The item should be handed in for recycling in
accordance with local environmental regulations for waste disposal.
By separating a marked item, you will help reduce the volume of waste
sent to incinerators or land-fill and minimize any potential negative impact
on human health and the environment.

3 System Overview
The figure below shows a typical layout with the SDU included for one engine.
3.1 DCU Engine Controller
The DCU Engine Controller is the main building block in the Marine Pro family.
Engine sensor values are displayed on the colour touch screen, and commands and other
user interaction is also here.
3.2 RP Remote Panel
The optional RP Remote Panel brings the DCU data and interface to a remote location with
no need for any configuration.
3.3 Ethernet Switch
It’s recommended to always use an Ethernet switch even though direct connection between
DCU and RP will work. PC connection for configuration and setup is also more convenient
with the Ethernet switch available.
Page 4 (15)

4 Installation
This chapter covers the installation of the SDU 404 and SDU 420.
4.1 General
The SDU 404 and SDU 420 are engine safety modules. They are primarily designed to be
used together with the Marine Pro family, although stand-alone operation is possible.
1
They can be installed separate from the DCU or in the same cabinet. The SDU units are
intended to be mounted on a DIN rail.
The engine shutdown switches shall be wired to the switch input channels on the SDU.
The two-wire SDU Link shall be established between the DCU and the SDU.
4.1.1 LED Overview
Details regarding indicators are described in the User’s manual but the illustration and the

4.2 Wiring
Follow these wiring guidelines.
4.2.1 DC Supply
Connect 24 VDC to terminals 1 (24 V) and 2 (0 V). Connect a ground connection to
terminal 3.
SDU supply wires shall have a minimum area of 0.5 mm2.
4.2.2 Switch Channels
Switch channels are configurable for loop monitoring and short circuit.
All switch channels use a two-wire layout, where both wires from the switch are to be routed
to the SDU.
Switch wires shall have a minimum area of 0.5 mm2.
Page 7 (15)

4.2.2.1 Broken Wire Detection
Requirement for type approved installations. Each switch shall have a 10 kΩ resistor
connected across.
The 10 kΩ resistors shall be connected directly at the switch, and not at the SDU.
Switches shall be normally open (NO), and shall close to indicate engine shutdown.
4.2.2.2 Short Circuit Detection
Each switch shall have a 10 kΩ resistor connected in series.
The 10 kΩ resistors shall be connected directly at the switch, and not at the SDU.
4.2.3 Analog Channels
Analog channels are available for shutdown configuration.
The 4-20 mA channels shall be powered from terminal 22.
The PT100 / PT1000 channels shall be connected according to the image below, depending
on whether it is a two wire or three wire sensor.
Analog channel wires shall have a minimum area of 0.5 mm2.

4.2.4 Pickup Channel
The SDU can operate with a magnetic or active pickup source. In case of an active pickup
source, the SDU needs to be configured properly.
Connect the pickup to terminals 4 and 5, with shield to terminal 3.
Make sure the cable shield is connected at the SDU side and not at the pickup
side.
4.2.5 Shutdown Override & Acknowledge Inputs
This is to be wired exactly like a Switch Input, that is; it shall be a normally open switch.
Close the switch to activate the function.
If broken wire detection is desired, connect a 10 kΩ resistor across the switch. If
short circuit detection is desired, connect a 10 kΩ in series with the switch. Make
sure the SDU configuration is matching this setup.
Typically, the Shutdown Override switch input is configured to detect broken wire.
Typically, the Acknowledge input is configured for no wire break detection.
4.3 DCU Communication
Depending on the DCU model, connect the wires in the shielded communication cable to the
terminals as shown in the table below:
SDU 404
SDU 420
DCU 410E /
DCU 408E

62 (H)
C1.6 (H)
24 (H)
Only connect the cable shield at one end.
To minimize the effect of external noise it is recommended to use twisted pair wires.
The SDU Link shall be terminated with a 120 ohm resistor at the end of the
communication link. Note that the DCU is already terminated internally.
Page 9 (15)

If there are several units attached to the
link then connect the 120 ohm resistor
together with the last unit on the bus only.
4.3.1 Connection Parameters
The two-wire SDU Link has fixed communication parameters.
The Baud rate is 19200 baud.
● 8 data bits
● 1 stop bit
● Even parity

When properly connected, the DCU will find the SDU automatically. To start using the SDU,
enable it via the DCU web interface.
The communication parameters are only relevant if using a 3rd party equipment to
communicate with the SDU.
4.3.2 Configuration Mismatch Warning
When the SDU is connected to the DCU, the DCU will analyze the configuration in the SDU
and compare it to the stored configuration in the DCU. If these do not match, the DCU will
give a “Configuration Mismatch” warning.
The warning can be acknowledged, but DCU login rights are required to reset this warning.
With login rights, the configuration can be copied from the DCU to the SDU, or vice versa.
Please see the relevant Marine Pro manual for further details.

4.4 Buttons
4.4.1 Acknowledge
This button is used to acknowledge alarms and faults. See User’s Manual for more details.
4.4.2 Overspeed Test
Press and hold the “Overspeed Test” button for more than two seconds to enter the
overspeed test mode. See User’s Manual for more details.
5 Configuration
5.1 Configure SDU using the DCU
The recommended method of configuring the SDU is to login to the DCU via the web
interface.
When logged in, enter the SDU section and configure the SDU.
Next, from the menu on the left, select the sub-section to be configured.
Press the Submit button after each configuration change.
The configuration is stored in the DCU’s current active configuration file. If a new
SDU is connected to the DCU the configuration is transferred to the SDU when it is
connected.
For more configuration information, please consult the Marine Pro 400E/200E Series
Configuration Manual.
