Initial Release Revision (Upgraded from former QIG ver. 1.2) 2020-11-24 Updated manual template. Minor adjustments. 2024-10-22 Updated for SDU 410 software version 1.50; Ethernet interface is per default disabled. Added a procedure to enable it if needed. Page 3 (18) -
Page 4: System Overview
2 System Overview The figure below shows a simple layout with the SDU included for one engine. 2.1 DCU Engine Controller A DCU 410/210 (E or Classic) Engine Controller unit is the main building block in a Marine Pro System. Engine sensor values are displayed on the color screen, and commands and other user interaction is also available from here. -
Page 5: Installation
It can be installed separate from the DCU or in the same cabinet. The engine shutdown switches shall be wired to the switch input channels on the SDU 410. The two-wire SDU Link shall be established between the DCU and the SDU. -
Page 6: Active Leds
Description LOAD REDUCTION LED lit when SDU is in load reduction state. That is, when any of the configured channels are indicating load reduction. RUNNING LED activates when the SDU senses engine speed above the configured setpoint, typically 400 RPM. TACHO 1 LED lit if engine speed is above 5 RPM. -
Page 7: Relays
Description detected a fault on the channel. The connected relay coil impedance must be in the range 300 to 700 ohms. SHUTDOWN OVERRIDE Broken loop, or a short to 0V or 24V, is detected on the Shutdown Override input. Connect a 10k resistor for loop detection. 3.3 Relays One relay is dedicated to Shutdown. -
Page 8: Wiring
Loop Detection Each switch input shall add a 10k resistor connected across. The 10k resistor shall be connected directly at the switch, and not at the SDU 410. Switches shall be normally open (NO), and shall close to indicate engine shutdown. -
Page 9: Shutdown Coil
Make sure a 10k resistor is connected across the switch. 3.5 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 410 DCU 410E / DCU 210E / DCU 210 /... -

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. 4 Configuration The SDU 410 has eight switch input channels, and two magnetic pickup channels. 4.1 Factory Default Configuration The SDU 410 comes with a predefined configuration from the factory. -
Page 11: Active Channels
Often, the default configuration can be used as is. If for instance channels 3 and 4 are not to be used, then connect a 10k loop detection resistor across the wire terminals on the respective channel. Without anything connected to an enabled channel the SDU will indicate a channel fault. 4.1.1 Active Channels Channels 1-5 are enabled and predefined according to the table below. -

When the time has elapsed, the channel is enabled. D – Still enabled in Shutdown Override Activating the Shutdown Override input does not disable these channels. E – RPM Enabled Dependent, threshold (rpm) Engine speed need to be above this setpoint to enable the channel. F –... -
Page 13: Configure Sdu Directly
This option should be selected only if the SDU is used standalone; without a DCU engine panel. As of SDU 410 software version 1.50, the Ethernet interface is default disabled for cyber security reasons. It can be enabled by the following Modbus accesses. - Page 14 Then, in the internet browser, type the IP address of the SDU. The default SDU 410 IP address is 192.168.1.100. An administrator can have changed the last digit to anything between 100 and 109. These are the only possible IP addresses on the SDU.

Page 15: Status Miscellaneous
Remember to press the Save button after each configuration change. 4.3.1 Status Miscellaneous Here, the SDU lists miscellaneous status for power supply and certain internal status. This is just an overview and no changes can be made here. 4.3.2 Status Channels This page gives a status of the eight switch shutdown channels. -
Page 16: Channels
Set the engine overspeed setpoint. Also set the time (in 1/10th sec) the engine is allowed above this setpoint before the SDU is activating engine shutdown. 4.3.4 Channels This page has the configuration for each of the eight switch channels. First, select a channel, and then press OK. -

4.3.5 Connections Configure communication parameters. IP address Set the last figure of the IP address. Unless there is an IP address conflict this should be set to 100. Modbus 2 ID Set the Modbus ID address for the COM 2 RS-485 Modbus communication port. Baudrate Set the Modbus baudrate, either 9600 or 19200 baud. -
