2 INTRODUCTION

The DSE 5510 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 5510 can be used to parallel with other DSE 5510 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 5560).

The DSE 5510 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.S. voltage monitoring.

• Power measurement.

• Communications capability (RS485 or RS232 including GSM/SMS functions)

• 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 5xxx 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 OPERATION

3.1 CONTROL

Control of the DSE 5510 module is via push buttons mounted on the front of the module with STOP/RESET, MANUAL, AUTO, ALARM MUTE/LAMP TEST and START functions. For normal

operation these are the only controls which need to be operated. The smaller push buttons are used to access further information such as engine instruments and load switching. Detail of their operation is covered later in this document.

The following descriptions detail the sequences followed by a module containing the standard ‘factory configuration’. Always refer to your configuration source for the exact sequences and timers observed by any particular module in the field.

CAUTION: - The module may instruct an engine start event due to external influences. Therefore, it is possible for the engine to start at any time without warning. Prior to performing any maintenance on the system, it is recommended that steps are taken to remove the battery and isolate supplies.

057-015 5510 OPERATING MANUAL ISSUE 11 07/07/09 AM 8

3.2 AUTOMATIC MODE OF OPERATION

Automatic mode is used to start the set in response to an external start requirement from another device. A number of options exist for the remote start input (selectable using 5xxx configuration software).

• Remote Start on Load input indicates to the controller that it should start the set, and run ‘off load’.

• Remote Start on Load input indicates to the controller that it should start the set, synchronise (if required) and share load with any other sets in the system.

• Remote Start on Load Demand input indicates to the controller that it should start the sets, synchronise (if required) and share load with any other sets in the system, automatically starting and stopping sets on changing load demand.

NOTE: - If a digital input configured to panel lock is active, changing module modes will

not be possible. Viewing the instruments and iis NOT affected by panel lock. If panel lock is active the Panel lock indicator (if configured) illuminates.

This mode is activated by pressing the pushbutton. An LED indicator beside the button will illuminate to confirm this operation.

Should the remote start input (if configured) become active then the following sequence is observed. To allow for short term or false remote start signals, the Start Delay timer is initiated. After this

delay, if the pre-heat output option is selected then the pre-heat timer is initiated and the corresponding auxiliary output (if configured) will energise.

NOTE:- If the Remote Start signal is removed during the Start Delay timer, the unit will

return to a stand-by state.

After the above delays the Fuel Solenoid (or enable ECU output if configured) is energised, then one second later, the Starter Motor is engaged.

NOTE:- If the unit has been configured for CAN Bus, compatible ECU’s will receive the start command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-004 for more information on utilising DSE modules with electronically controlled engines.

The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond the set number of attempts, the start sequence will be terminated and Fail to Start fault will be displayed.

Shutdown Failed to start

DSE Model 5510 Autostart Control and Instrumentation System Operators Manual

057-015 5510 OPERATING MANUAL ISSUE 11 07/07/09 AM 9

When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency measured from the alternator output. Alternatively, a Magnetic Pickup mounted on the flywheel housing can be used for speed detection (This is selected by PC using the 5xxx series configuration software). Rising oil pressure can also be used to disconnect the starter motor, however it cannot be used for underspeed or overspeed detection.

NOTE:- If the unit has been configured for use with an electronic engine, speed sensing

is via the data-link.

After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure, High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.

If the system has been started by a ‘remote start off load’ input, the set will run ‘off load’. Otherwise, the Warm Up timer, if selected, is initiated, allowing the engine to stabilise. After the Warm-up timer has expired then the module will close the load switching device.

In the case of a single generator system, the Generator Contactor/Breaker will be instructed to close. The generator will then supply the requirements of the load.

On a multi-set system, if the common generator bus is live, the 5510 module will first synchronise the generator to the bus before closing the Generator Contactor/Breaker. A ‘token‘ is held by the module that first closed onto the dead bus and as only one token exists for each multi-set system, this prevents other sets in the system from attempting to close their own breakers. For added security, the modules also monitor the bus. If this is found to be live, then the synchronisation process begins.

Once the load switching device is closed, the 5510 will then ramp to share the load with the other generators in the system.

NOTE:-A load transfer will not be initiated until the Oil Pressure has risen. This prevents

excessive wear on the engine.

When the Remote start signal is removed, the Stop delay timer is initiated. Once this has expired, the module will ramp the load from the generator to remaining set (Multi-set systems only). The Generator Contact/Breaker will open and the Cooling timer is then initiated, allowing the engine a cooling down period off load before shutting down. Once the Cooling timer expires, the Fuel Solenoid is de-energised, bringing the generator to a stop.

For full details of multi-set operation please refer to the manual ‘The Guide to sync and load share Pt1’

Should the Remote Start signal be re-activated during the cooling down period, the set will return on load.

NOTE:- When synchronising is enabled, the bus is checked before closing any load switching device. If the bus is live, synchronising will take place before any closure takes place.

NOTE:- Synchronising can be disabled if the application does not require this function. Contact your genset supplier in the first instance for further details.

057-015 5510 OPERATING MANUAL ISSUE 11 07/07/09 AM 10

NOTE:- The internal ‘Scheduler’ can be configured to operate the system in the same manner as described for the Remote start input. Please refer to the 5xxx Configuration Software manuals for full details on the feature.

057-015 5510 OPERATING MANUAL ISSUE 11 07/07/09 AM 11

3.3 MANUAL OPERATION

Manual mode is used to allow the operator to control the operation of the generator, and to provide fault finding and diagnostic testing of the various operations normally performed during Automatic mode operation.

NOTE:- If a digital input configured to panel lock is active, changing module modes will

not be possible. Viewing the instruments and event logs iis NOT affected by panel lock. If panel lock is active the Panel lock indicator (if configured) illuminates.

MANUAL, mode is selected by pressing the pushbutton. An LED besides the button will

illuminate to confirm this operation. When the START (I) button is operated, the module will initiate

the start sequence.

NOTE: - There is no Start Delay in this mode of operation.

If the pre-heat output option has been selected, this timer will be initiated and the auxiliary output selected energised.

After the above delay, the Fuel Solenoid (or ECU output if configured) is energised, and then one second later, the Starter Motor is engaged.

Alarm

Shutdown Fail to start

When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency measured from the Alternator output. Alternatively, a Magnetic Pickup mounted on the flywheel housing can be used for speed detection (This is selected by PC using the 5xxx series configuration software). Rising oil pressure can also be used to disconnect the starter motor; however, it cannot be used for underspeed or overspeed detection.

NOTE:- If the unit has been configured for CAN Bus, speed sensing is via CAN Bus.

Once the engine is running, the Warm Up timer (if selected) is initiated, allowing the engine to stabilise before it can be loaded. Once the warm up timer has expired the generator is then available to go on load and the Generator Available LED will illuminate on the front panel.

DSE Model 5510 Autostart Control and Instrumentation System Operators Manual

057-015 5510 OPERATING MANUAL ISSUE 11 07/07/09 AM 12

If the module has been configured for synchronising and has speed control of the engine governor, during off load running, the engine speed can be changed using the “running editor”. The speed control options are not displayed in the editor unless the engine is running OFF LOAD in MANUAL MODE. Details of how to access the ‘running editor’ are contained elsewhere in this manual.

The generator will run off load unless:

1. A Remote Start on load signal is applied

2. An on-load run is configured in the scheduler.

3. The Close Generator button is pressed.

On a multi-set system, if the common generator bus is live, the 5510 module will first synchronise the generator to the bus before closing the Generator Contactor/Breaker to close. A ‘token‘ is held by the module that first closed onto the dead bus and as only one token exists, this prevents other sets in the system from attempting to close their own breakers. For added security, the modules also monitor the bus. If this is found to be live, then the synchronisation process begins.

During the parallel run the module can be configured to either run at a fixed level output, such as when used in parallel with an infinite bus. Alternatively, it can be configured to load share with other generators on the bus. For full details of these mode please refer to the manual ‘The Guide to sync and load share Pt1’

• If the Open Generator button is pressed while in parallel, the module will ramp the load

on the remaining generators and then open the generator contactor/breaker.

• If the Open Generator button is pressed and the generator is connected to the

common generator bus then the load is ramped off the generator and the contactor/breaker is opened.

If Auto mode is selected and the remote start on load signal not active, and the scheduler is not calling for a run, then the Return Delay Timer will start.

Once this has expired then the module will exit parallel operation and will ramp the load back to the remaining generators. It will then open the Generator Contactor/Breaker. The generator will then run off load allowing the engine a cooling period.

Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.

WARNING: - Operation of the STOP button in any mode will stop the generator operation and return the load switching system to a safe state. This operation may lead to loss of supply to the load. It is recommended that the STOP button is only operated once the generator is OFF LOAD and the mains supply provides power to the load.

NOTE: - Synchronising can be disabled if the application does not require this function. Contact your genset supplier in the first instance for further details.

NOTE: - When synchronising is enabled, the bus is checked before closing any load switching device. If the bus is live, synchronising will take place before any closure takes place.

NOTE:- Upon closing the load switching device, the module checks that the bus becomes live. If it does not, an alarm is generated to indicate the problem.

4.2 ANALOGUE PRE-ALARMS

The following alarms are termed ‘pre-alarms’ as they pre warn the operator of a potentially more serious alarm condition. For instance, if the engine temperature rises past the pre alarm level, a warning condition will occur to notify the operator. If the temperature falls below this level, then the alarm ceases and the set will continue to run as normal. However if the temperature continues to rise until the coolant temperature trip point is reached, the warning is escalated and a high coolant temperature shutdown is initiated.

LOW OIL PRESSURE, if the module detects that the engine oil pressure has fallen below the low oil pressure pre-alarm setting level after the Safety On timer has expired, a warning will occur. Alarm Warning Low Oil Pressure will be displayed.

4.3 SHUTDOWNS

Shutdowns are latching and stop the Generator. The alarm must be cleared and the fault removed to reset the module.

NOTE:- The alarm condition must be rectified before a reset will take place. If the alarm condition remains it will not be possible to reset the unit (The exception to this is the Low Oil Pressure alarm and similar ‘delayed alarms’, as the oil pressure will be low with the engine at rest).

FAIL TO START, if the engine does not fire after the pre-set number of attempts has been made a

shutdown will be initiated. Alarm Shutdown Fail To Start will be displayed.

Alarm

Shutdown Fail to start

EMERGENCY STOP, removal of the positive DC Supply from the Emergency Stop input will initiate

a shutdown of the Generator and prevent any attempt to restart the Generator until the Emergency Stop push-button has been reset. Additionally it removes the positive DC supply from both the Fuel Solenoid and Starter Solenoid.

Alarm Shutdown Emergency Stop will be displayed.
