 Introduction

1 INTRODUCTION
This document details the use of the DSE Configuration Suite PC Software with the DSEE100
module, which is 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.deepseaelectronics.com

The DSE Configuration Suite PC Software allows the DSEE100 module to be connected to a PC via
USB A to USB B cable (USB printer cable). Once connected, the software allows easy, controlled
access to various operating parameters within the module which can then be viewed and edited as
required.

The DSE Configuration Suite PC Software must only be used by competent, qualified personnel, as
changes to the operation of the module may have safety implications on the panel / generating set to
which it is fitted. Access to critical operational sequences and settings for use by qualified engineers,
may be barred by a security code set by the engine provider.

The information contained in this manual must be read in conjunction with the information contained
in the appropriate module documentation. This manual only details which settings are available and
how they may be used. Separate manuals deal with the operation of the individual module and its
ancillaries, refer to section entitled Bibliography elsewhere in this document for further information.

2.3.6 INPUT FUNCTIONS

Where a digital input is not configured as “user configured”, a selection is made from a list of
predefined functions. The selections are as follows:

Under the scope of IEEE 37.2, function numbers can also be used to represent functions in
microprocessor devices and software programs. Where the DSE input functions can be represented
by IEEE 37.2, the function number is listed below.

Input Function Description

Alarm Mute This input is used to silence the audible alarm from an external source such
as a remote mute switch.
Alarm Reset This input is used to reset any latched alarms from a remote location. It is
also used to clear any latched warnings which may have occurred (if
configured) without having to stop the engine.
Auto Start Inhibit
IEEE 37.2 - 3 NOTE: This input does not prevent starting of the engine in
Checking Or Interlocking Manual mode.
Relay
This input is used to provide an over-ride function to prevent the controller
from starting the engine in the event of a start request in auto mode. If this
input is active and a start signal occurs, the module does not give a start
command to the engine. If this input signal is then removed, the controller
operates as if a start request has occurred, thus starting the engine.
Coolant Temperature This input is used to give a Coolant Temperature High shutdown from a
Switch digital normally open or normally closed switch.
Disable Protections The system designer provides this switch (not DSE) so its location varies
depending upon manufacturer, however it normally takes the form of a key
operated switch to prevent inadvertent activation. Depending upon
configuration, a warning alarm is generated when the switch is operated.
When active, and the module is suitably configured (see section entitled
‘Advanced’) this prevents the engine being stopped upon critical alarm
(Sometimes called Battle-Short Mode, War Mode or Run to Destruction)
Emergency Stop Provides an immediate engine hot shutdown, used in emergency situations
External Panel Lock
NOTE: External control sources (i.e. Simulate Start Button) are not
affected by the external panel lock input and continues to operate
normally.

This input is used to provide security to the installation. If the External Panel
lock input is active, the module does not respond to operation of the Mode
select or start buttons. This allows the module to be placed into a specific
mode (such as Auto) and then secured. The operation of the module is not
affected, and the operator is still able to view the various instrumentation
pages etc. (Front panel configuration access is still possible while the
system lock is active).
Lamp Test This input is used to provide a test facility for the front panel indicators fitted
to the module. When the input is activated all LEDs illuminate.
Low Fuel Level Switch This input is used to give a Low Fuel Level Switch shutdown from a digital
normally open or normally closed switch.
Maintenance Reset Provides an external digital input to reset the maintenance alarm
Alarm Air
Maintenance Reset Provides an external digital input to reset the maintenance alarm
Alarm Fuel
Maintenance Reset Provides an external digital input to reset the maintenance alarm
Alarm Oil

Input Function Description

Oil Pressure Switch This input is used to give Oil Pressure Switch shutdown from a digital
IEEE 37.2 – 63 normally open or normally closed switch.
Pressure Switch
Remote Start When in auto mode, this input is used to perform the start sequence.

Remote Stop When in auto mode, this input is used to perform the stop sequence.

Simulate Auto Button

NOTE: If a start request is present when Auto mode is entered,
the starting sequence begins. Start requests are generated from a
number of sources depending upon module type and configuration
and includes (but is not limited to): Remote Start input present,
Scheduled Run and Telemetry Start signal from remote locations.

This input mimics the operation of the ‘Auto’ button and is used to provide a
remotely located Auto mode push button.
Simulate Start Button This input mimics the operation of the ‘Start’ button and is used to provide a
remotely located start push button.
Simulate Stop Button This input mimics the operation of the ‘Stop’ button and is used to provide a
remotely located stop/reset push button.
Smoke Limiting This input instructs the module to issue a Run At Idle Speed command to
IEEE 37.2 – 18 the engine via an output configured to Smoke Limit.

2.5 TIMERS
Many timers are associated with alarms. Where this occurs, the timer for the alarm is located on the
same page as the alarm setting. Timers not associated with an alarm are located on the timer’s page.
The Timers section is subdivided into smaller sections. Select the required section with the mouse.

2.5.1 START TIMERS

Timer Description
Start Delay The amount of time delay before starting in AUTO mode. This timer is
activated upon the Remote Start On Load command being issued.
Typically this timer is applied to prevent starting upon fleeting start signals.
Pre-heat The amount of ‘prestart’ time during which the Preheat output becomes active
(if configured)
Cranking The amount of time for each crank attempt
Cranking Rest The amount of time between multiple crank attempts.
Smoke Limiting The amount of time that the engine is requested to run at idle speed upon
starting. This is typically used to limit emissions at start up.
Smoke Limiting Off The amount of time that the engine takes to run up to rated speed after
removal of the command to run at idle speed. If this time is too short, the
engine is stopped due to an Underspeed alarm. If the time is too long,
Underspeed protection is disabled until the Smoke Limit Time Off time has
expired.
Safety On Delay The amount of time at startup that the controller ignores oil pressure and
engine speed and other delayed alarms. This is used to allow the engine to
run up to speed before protections are activated.
Warming The amount of time the engine runs before activating the Engine Available
output. This is used to warm the engine to prevent excessive wear.

 Edit Configuration

2.5.2 LOAD / STOPPING TIMERS

Timer Description
Return Delay The amount of time, in auto mode only, that allows for short term removal of
the request to stop the engine before action is taken. This is used to ensure
the engine remains on load before accepting that the start request has been
removed.
ETS Solenoid Hold The amount of time the Energise to Stop output is kept energised after the
engine has come to rest. This is used to ensure the set has fully stopped
before removal of the stop solenoid control signal.
Fail To Stop Delay If the set is called to stop and is still running after the fail to stop delay, a Fail
to Stop alarm is generated.

2.5.3 MODULE TIMERS

Timer Description
Power Save Mode If the module is left unattended in STOP mode for the duration of the
Delay Power Save Mode Delay it enters low power consumption mode (Power
Save Mode).
Deep Sleep Mode When the module is in Power Save Mode, if left unattended for the

Startup Options

Parameter Description
Start Attempts The number of starting attempts the module makes.
If the module does not detect that the engine has fired before the end of the
Cranking Time, then the current start attempt is cancelled, and the Crank Rest time
takes place before the next crank attempt begins.
If, after all configured start attempts, the engine is not detected as running, the Fail
to Start shutdown alarm is generated.

The engine is detected as running by checking all methods of Crank Disconnect.

For further details, see the section entitled Crank Disconnect elsewhere in this
document.
Loss of Sensing If the speed sensing signal is lost during engine running (or not present during
Signal cranking when Multiple Engage Attempts is enabled), an alarm is generated:

Overspeed Options

Parameter Description
Overspeed To prevent spurious overspeed alarms at engine start up, the module includes
Overshoot % configurable Overspeed Overshoot protection.
This allows the engine speed to ‘overshoot’ the Overspeed setting during the
starting process for a short time.
The DSE module ignores the Overspeed alarms when the speed increases by the
Overspeed Overshoot % of the Over Speed Alarm Trip level for the duration of
Overspeed Overshoot Delay timer.
Overspeed Rather than ‘inhibiting’ the Overspeed alarms, the levels are temporarily raised by

2.6.3 CRANK DISCONNECT

Cranking settings are used to detect when the set fires during the starting sequence.
As the set is cranked, the first parameter that passes its crank disconnect setting results in the
cessation of the cranking signal.

Having more than one crank disconnect source allows for a much faster crank disconnect response
leading to less wear on the engine and starter components and provides added safety in case one
source is lost, by a blown or tripped fuse for example.

3.9.6 SPEED CALIBRATION

NOTE: The prerequisites of speed calibration must be fulfilled to successfully carry out
the Speed Calibration. During the procedure the engine speed must be between 600 rpm
and 8000 rpm and the resultant pulses per revolution must be between 2.0 and 50.0.

The Speed Calibration procedure is designed for reading engine speed via the charge alternator
tachometer terminal, by calculating the ratio between crankshaft speed and charge alternator
speed.

Prerequisites:

• Set the Pulses Per Rev initially to zero.

• Set Crank Disconnect On Oil Pressure to enabled when an oil pressure sensor is
configured.
• Disable the Under Speed Shutdown.

After the prerequisites have been fulfilled the engine is started, current engine speed (measured by
an external device chosen by the commissioner) is entered into the Current Engine Speed setting
and the calibration is activated. The module then calculates the new value for the Pulses Per
Revolution and writes the value into the module’s configuration. Once the calibration is complete,
the Under Speed Shutdown must be re enabled by reading the configuration from the module and
checking Enable in the Engine | Speed Settings tabs.

 Alarm Types

4 ALARM TYPES
The protection included with the DSE control modules provides increasing levels of notification,
depending upon the severity of the situation:

Alarm type Description

Indication No audible alarm or common warning signal occurs.
Indication alarms are only used to illuminate indicators or to activate
outputs.
Warning Audible alarm and common alarm signal is generated. The set
continues to run.
Warning alarms are used to draw the operator’s attention to a minor
issue or to a problem that may escalate to a Shutdown Alarm if left
untreated.
Shutdown Audible alarm and common alarm signal is generated. The engine is
taken off load and immediately stopped.
Shutdown alarms are serious issues that demand immediate stopping
of the engine. For instance Emergency Stop or Overspeed alarms
require immediate shutdown.

Delayed Shutdown Over Speed
(Overspeed Overshoot Delay)

Example

1700 rpm Over Speed setting, 10% Overspeed Overshoot

During Safety Delay an engine speed above (1700 rpm x 1.1) = 1870 rpm results in an immediate
shutdown without delay.
After Safety delay, an engine speed above 1700 rpm for the period of the Speed Transient Delay
results in a shutdown.
