1 INTRODUCTION
This document details the operation and setup requirements of the DSEM840 Mobile Controller and
Display, part of the DSEControl
®
range of products.
The manual forms part of the product and should be kept for the entire life of the product. If the
product is passed or supplied to another party, ensure that this document is passed to them for
reference purposes.
This is not a controlled document. DSE do not automatically inform on updates. Any future updates of
this document are included on the DSE website at www.deepseaplc.com
Observe the operating instructions. Non-observance of the instructions, operation not in accordance
with use as prescribed below, wrong installation or incorrect handling seriously affects the safety of
operators and machinery.
A robust metal case designed for chassis mounting houses the module. Connections are via locking
plug and sockets.
The controller is supplied with no application program. The equipment manufacturer is responsible for
creating and managing the application program and installing it in the controller. This is achieved
using CODESYS V3.5 or C programming. Contact DSE Technical Support for further details.

1.1 CLARIFICATION OF NOTATION
Clarification of notation used within this publication.
NOTE:
Highlights an essential element of a procedure to ensure correctness.
CAUTION!
Indicates a procedure or practice, which, if not strictly observed, could
result in damage or destruction of equipment.
WARNING!
Indicates a procedure or practice, which could result in injury to
personnel or loss of life if not followed correctly.
1.2 GLOSSARY OF TERMS
Term
Description
Application The application is the program that allows the DSEM840 to control the
machine it is connected to.
The Application within the DSEM840 is designed and provided by the
manufacturer of the complete machine.
Bootloader The Bootloader is the program within the DSEM840 responsible for loading
the Operating System.
CAN Control Area Network. A high-speed data transmission system used
extensively within the Automotive and Off-Highway industries.
CODESYS
(Previously stylised
as CoDeSys)
Integrated Development Environment for programming controller
applications according to the international industrial standard IEC 61131-3.
DSEM840 supports CODESYS V3.5
ECU Electronic Control Unit. For example the DSEM840 device.
Firmware The Firmware of the DSEM840 is the Operating System of the DSEM840
that reads and executes the Application program.
FSD Full Scale Deflection. For example 0 mA to 20 mA is the Full Scale
Deflection of a current sink input.
I/O Input / Output. For example “The I/O is taken out to an external terminal
strip in the user panel”.
IDE Integrated Development Environment. For example the CODESYS V3.5
application that runs on the host PC is an IDE.
Ixyyy An Input, where x is the connector and yyy is the input number. For
example IA003 means Input 3 on Connector A.
PLC Programmable Logic Controller. Industrial computer used primarily for the
automation of electromechanical machinery.
PWM
PWMi A digital signal is used to represent an analogue value by using Pulse Width Modulation. The mark-space ratio of a square wave changes to
represent the value.
Used for many control applications including proportional valves.
PWM= Voltage control.
PWMi = Current control.
Off-Highway An industrial vehicle used primarily “off road”. For example construction
and farm machinery. A wider interpretation includes on road access
platforms, emergency vehicles and other industrial machinery, used either
on the road, or off road.
Pin A male or female pin connection in a housing (plug or socket).
Qxyyy An Output, where x is the connector and yyy is the output number. For
example QA002 means Output 2 on Connector C.

1.4 SAFETY INSTRUCTIONS
1.4.1 GENERAL
•These instructions are for authorised persons according to the EMC and low-voltage directives.
The device must be installed, connected and put into operation by a qualified electrician.
•It is not permissible to open the controller or to modify or repair the controller. Modification or
repairs to the wiring could result in dangerous malfunctions. Repairs to the controller must be
performed by DSE. Contact your original equipment supplier in the case of malfunction.
•When the device is unpowered, ensure that no connection pins are connected to a voltage
source. Thus, when the supply is switched off, the supply for the electronics, the power outputs
and the external sensor supply must be switched off together.
•The customer is responsible for performing risk analysis of the mobile working machine and
determining the possible safety related functions. The user is responsible for the safe function of
the application programs created. If necessary, they must additionally carry out an approval test
by corresponding supervisory and test organisations according to the national regulations.
•All connectors must be unplugged from the electronics during electrical welding and painting
operations.
1.4.2 INSTALLATION NOTES
•Follow the instructions of the connector manufacturer, specifically with respect to preventing
water from entering the device. See Section entitled Cables, Connectors, Harnesses and Spare
Parts for details of DSE Part Numbers.
•M12 protection plugs (supplied) must be installed in both the USB and Ethernet interfaces to
ensure IP67 rating when the connectors are not in use. Where IP protection is required when the
interfaces are in use, suitable O-rings must be fitted.

2.3.2 IGNITION (Pin A13)
NOTE: Ignition (Pin A13) must be utilised correctly to enable / disable the application
program. This ensures that logs and other changed parameters are stored when the Ignition is
switched off.
Pin A7 is used to give a constant DC supply to the DSEM840, with the Ignition pin being used to
energise and de-energise the ECU. Typically, this pin is controlled by an external ignition switch.
To stop the application, de-energise the Ignition pin. This allows the DSEM840 to store any changed
parameters and logs before closing down.
