2 INTRODUCTION
This document details the installation and operation requirements of the DSE7500 Series modules,
part of the DSEPower® 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. You will not be automatically informed of updates. Any future
updates of this document will be included on the DSE website at www.deepseaplc.com
The DSE7560 Mk1 controller is an update to the popular DSE7560. It maintains all the
functions and flexibility of the DSE5560 while being packaged in DSE7000 series styling
bringing with it the advantages of the DSE7000 series terminal compatibility easing system
upgrades. The DSE7560 Mk1 controller is compatible with DSE5560 and DSE556 controllers
when used in a multiple controller system, connected by the MSC (Multi-Set
Communications) Link.
The DSE 7560MK1 Module allows the OEM to meet demand for increased capability within the
industry. It allows the user to start and stop the generator and if required, transfer the load to the
generator either manually or automatically. The user also has the facility to view the system
operating parameters via the LCD display.
Utilising the inbuilt synchronising, volts matching and paralleling functions, the controller is able to
parallel with the mains supply for simple peak lopping (fixed generator output). Alternatively, the
7560MK1 can be used to parallel with other DSE 7560MK1 load sharing controllers. Up to 16 sets
can be connected in paralleling and load share as a standalone (prime power) system. Additionally
they can parallel with the mains supply (when used in conjunction with DSE 7560MK1).
The DSE 7560MK1 module also monitors the engine, indicating the operational status and fault
conditions, automatically shutting down the engine. Exact failure mode information is indicated by the
LCD display on the front panel.
The powerful Microprocessor contained within the module allows for many features to be
incorporated as standard;
•Full Multilingual LCD display (including non-western character fonts).
•True R.M.Ss. voltage monitoring.
•Power measurement.
•Communications capability (RS485)
•Check Sync capability
•Automatic Sync capability
•Load share / control capability
•Fully configurable inputs for use as alarms or a range of different functions also available on
P130 expansion inputs (optional)
•Extensive range of output functions using built in relay outputs or relay expansion available.
•Instrumentation and diagnostics from electronic engines when connected to an engine ECU.
Selective operational sequences, timers and alarm trips can be altered by the customer via a PC
using the 75xx For Windows ™ software and 810 interface or via the integral front panel
configuration editor.
Access to critical operational sequences and timers for use by qualified engineers, can be protected
by a security code. Module access can also be protected by PIN code. Selected parameters can be
changed from the module’s front panel.
The module is housed in a robust plastic case suitable for panel mounting. Connections to the
module are via locking plug and sockets.

3.10.1 FIXING CLIPS
The module is held into the panel fascia using the supplied fixing clips.
•Withdraw the fixing clip screw (turn anticlockwise) until only the pointed end is protruding
from the clip.
•Insert the three ‘prongs’ of the fixing clip into the slots in the side of the 7000 series module
case.
•Pull the fixing clip backwards (towards the back of the module) ensuring all three prongs of
the clip are inside their allotted slots.
•Turn the fixing clip screws clockwise until they make contact with the panel fascia.
•Turn the screws a little more to secure the module into the panel fascia. Care should be
taken not to over tighten the fixing clip screws.
NOTE:- In conditions of excessive vibration, mount the module on suitable anti-vibration
mountings.

3.10.2 CABLE TIE FIXING POINTS
Integral cable tie fixing points are included on the rear of the module’s case to aid wiring. This
additionally provides strain relief to the cable loom by removing the weight of the loom from the
screw connectors, thus reducing the chance of future connection failures.
Care should be taken not to over tighten the cable tie (for instance with cable tie tools) to prevent
the risk of damage to the module case.

3.10.3 SILICON SEALING GASKET
The supplied silicon gasket provides improved sealing between the 7000 series module and the
panel fascia.
The gasket is fitted to the module before installation into the panel fascia.
Take care to ensure the gasket is correctly fitted to the module to maintain the integrity of the seal.

4.2.5 MAINS AND BUS CURRENT TRANSFORMERS
WARNING!:- Do not disconnect this plug when the CTs are carrying current.
Disconnection will open circuit the secondary of the C.T.’s and dangerous voltages may
then develop. Always ensure the CTs are not carrying current and the CTs are short circuit
connected before making or breaking connections to the module.
NOTE:- The DSE7510 MK1 module has a burden of 0.5VA on the CT. Ensure the CT is
rated for the burden of the DSE7510 MK1 controller, the cable length being used and any
other equipment sharing the CT. If in doubt, consult your CT supplier.

4.2.7 PC CONFIGURATION INTERFACE CONNECTOR
8-way connector allows connection to PC via 810 configuration
interface. Module can then be re-configured utilising the 75xx
for Windows™ software.
CAUTION!: This socket must not be used for any other purpose.
4.2.8 EXPANSION INTERFACE CONNECTOR
4-way connector allows connection to the P130 input
expansion, P157 relay expansion module or 545/548 LED
expansion modules.
A maximum of 2 relay or LED expansion modules may be
connected in series to this port.
CAUTION! - Do not connect the 808 configuration interface to this port, as it is not
possible to use the 808 software to configure the 7560MK1 module.
CAUTION!: This socket must not be used for any other purpose.
