1 INTRODUCTION
This document details the installation and operation requirements of the DSE335 module version 4.2
and later, part of the DSEATS® range of products.
A separate document covers the DSE335 modules with firmware version prior to version 4.2.
The manual forms part of the product and must 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. Updates are not automatically informed. Any future updates of this
document are included on the DSE website at www.deepseaplc.com
The module is designed to provide differing levels of functionality across a common platform. This
allows the OEM greater flexibility in the choice of controller to use for a specific application.
The module has been designed to allow the operator to control the transfer of the load from Source 1
(S1) to Source 2 (S2), typically the mains supply and a standby generator either manually (via fascia
mounted push-buttons) or automatically upon S1 failure. Additionally if configured too, the module
automatically starts and stops the generator set (S2) depending upon the status of S1.
The user also has the facility to view the system operating parameters via the LCD display to monitor
the supplies and indicating the operational status and fault conditions of the module.
The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:
• Text based LCD display (supporting multiple languages)
• True RMS Voltage, Current and Power monitoring
• Communications capability (RS485 or RS232)
• Multiple AC supply monitoring
• Fully configurable inputs for use as alarms or a range of different functions.
Using a PC and the DSE Configuration Suite software allows alteration of selected operational
sequences, timers, alarms and operational sequences. Additionally, the module’s integral front panel
configuration editor allows adjustment of this information.
A robust plastic case designed for front panel mounting houses the module. Connections are via
locking plug and sockets.
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.
