DSE Model 5220 Automatic Mains Failure & Instrumentation System Operators Manual
5220 OPERATING MANUAL ISSUE 5.1 18-Jun-07 AM 5
1 INTRODUCTION
The DSE 5220 automatic mains failure module has been designed to allow the OEM to meet most of the industry’s
complex specifications. It has been primarily designed to monitor the mains (utility) supply, starting the generator
automatically should it fall out of limits. Transfer of the load is automatic upon a mains supply failure. If required the
generator and can be started and stopped manually, and if required, the user can transfer the load to the generator
either manually (via external push-buttons) or automatically. The user also has the facility to view all the system
operating parameters via the LCD display.
The DSE 5220 module monitors the mains (utility) supply indicating the status of the mains on the module’s
integral LCD display. Additionally the module monitors the engine, indicating the operational status and fault
conditions, automatically shutting down the engine and giving a true first up fault condition of an engine failure by a
flashing common alarm LCD indicator. The exact failure mode is indicated by combined “hidden ‘til lit” LEDs and
the LCD display on the front panel.
The powerful microprocessor contained within the module allows for a range of complex features to be
incorporated as standard:
•Graphical Icon based LCD display (excluding the need for translations and languages).
•Voltage, Current and Power monitoring.
•Engine parameter monitoring.
•Fully configurable inputs for use as alarms or a range of different functions.
•Extensive range output functions using built in relay outputs or relay expansion available.
Selective operational sequences, timers and alarm trips can be altered by the customer via a PC using the 5200
series configuration software and P810 interface. Additionally, a subset of this information can be adjusted from the
module’s front panel configuration editor.
The module is housed in a robust plastic case for front panel mounting. Connections to the module are via locking
plug and sockets.

DSE Model 5220 Automatic Mains Failure & Instrumentation System Operators Manual
5220 OPERATING MANUAL ISSUE 5.1 18-Jun-07 AM 7
Whether the start sequence is initiated by mains (utility failure) or by remote start input, the follow sequence is
followed :
To allow for short term mains supply transient conditions 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 mains supply returns within limits, ( or the Remote Start signal is removed if the start
sequence was initiated by remote start) during the Start Delay timer, the unit will return to a stand-by
state.
After the above delays the Fuel Solenoid is energised, then one second later, the Starter Motor is engaged.
The engine is cranked for a pre-set time period. 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 accompanied by a flashing shutdown symbol.
When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency 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 5200 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.
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.
Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to stabilise before
accepting the load.
If an auxiliary output has been selected to give a load transfer signal, this would then activate.
NOTE:-A load transfer will not be initiated until the Oil Pressure has risen. Thus preventing
excessive wear on the engine.
On the return of the mains supply, (or removal of the Remote Start signal if the set was started by remote signal) ,
the Stop delay timer is initiated, once it has timed out, the load Transfer signal is de-energised, removing the load.
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.
Should the mains supply fall outside limits again (or the Remote Start signal is re-activated) during the cooling
down period, the generating set will return to a on load condition.

3.2 MANUAL OPERATION
NOTE:- If a digital input configured to panel lock is active, the LCD will display the icon. When in
panel lock, changing module modes will not be possible. Viewing the instruments and event logs
is NOT affected by panel lock.
To initiate a start sequence in MANUAL, press the pushbutton. When the controller is in the manual mode
(indicated by an LED indicator beside the button), pressing the START (I) button will initiate the start sequence.
NOTE:- There is no Start Delay in this mode of operation.
If the pre-heat output option is selected this timer is then initiated, and the auxiliary output selected is energised.
The Fuel Solenoid is energised, then the Starter Motor is engaged.
The engine is cranked for a pre-set time period. 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 accompanied by a
flashing shutdown indicator.
When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from the Alternator

the starter motor, however it cannot be used for underspeed or overspeed detection.
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.
Once the engine is running, the Warm Up timer, if selected, is initiated, allowing the engine to stabilise before it
can be loaded.
The generator will run off load, unless the mains supply fails or a Remote Start on load signal is applied. If Close
generator has been selected as a control source, the appropriate auxiliary output will then activate.
The generator will continue to run On load regardless of the state of the mains supply or remote start input until the
Auto mode is selected.
If Auto mode is selected, and the mains supply is healthy with the remote start on load signal not active, then the
Remote Stop Delay Timer begins, after which, the load is disconnected. The generator will then run off load
allowing the engine a cooling down period.
Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.

4 PROTECTIONS
The module will indicate that an alarm has occurred in several ways;
The LCD display will indicate a ‘common alarm’ either :
(warning), (shutdown) or
(electrical trip)
If appropriate, the LCD display or LED indicators will display the
appropriate alarm icon i.e. for battery charging failure :
NOTE:- Alarm icons in the LED display area are ‘hid until lit’. This means that the display area
appears totally clear, and ‘free from clutter’. The advantage of this is that when an alarm does occur,
the respective LED icon will illuminate on the otherwise blank fascia. This makes alarm identification
much clearer.
If no alarms are present the LCD
will extinguish any alarm icons.
In the event of a warning alarm the LCD will display the appropriate icon. If a shutdown then occurs the module
will display the appropriate icon. The original warning alarm icon will remain displayed.
Example:-
Low battery volts warning (all symbols steady)
Followed by….
Low battery volts warning indicator still
present, common alarm indicator has
changed to a shutdown symbol and is
now flashing.
Also present is the flashing underspeed
LED.
Underspeed and Shutdown alarm Icons are displayed flashing. The original warning will remain displayed as long
at the triggering conditions remain. Any subsequent warnings or shutdowns that occur will be displayed steady,
therefore only the first-up shutdown will appear flashing.

4.1 WARNINGS
Warnings are non-critical alarm conditions and do not affect the operation of the generator system, they serve to
draw the operators attention to an undesirable condition.
In the event of a warning alarm the LCD will display:-
BATTERY CHARGE FAILURE, if the module does not detect a voltage from the warning light terminal on the
auxiliary charge alternator the icon will illuminate.
BATTERY LOW VOLTAGE, if the module detects that the plant DC supply has fallen below the low volts setting
level, the module will display:-
V
The Battery Low Voltage alarm is delayed by the Low DC Volts Delay timer.
BATTERY HIGH VOLTAGE, if the module detects that the plant DC supply has risen above the high volts setting
level, the module will display:-
V
The Battery High Voltage alarm is delayed by the High DC Volts Delay timer.
FAIL TO STOP, If the module detects the engine is still running when the ‘Fail to stop timer’ expires, then the
module will display:-
NOTE:- ‘Fail to Stop’ could indicate a faulty oil pressure sender - If engine is at rest check oil sender
wiring and configuration.
AUXILIARY INPUTS, if an auxiliary input has been configured as a warning the appropriate LCD segment will be
displayed:-
!
LOW FUEL LEVEL. If the fuel level detected by the fuel level sender falls below the low fuel level setting, a
warning will occur.
The icon will illuminate.
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.
During a pre-alarm condition, the warning symbol is displayed on the LCD display, along with the appropriate
icon:
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.

module.
In the event of a shutdown alarm the LCD will display:-
(flashing).
The appropriate icon will also be displayed flashing
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). Any subsequent
warnings or shutdowns that occur will be displayed steady, therefore only the first-up shutdown will
appear flashing.
FAIL TO START, if the engine does not fire after the pre-set number of attempts has been made a shutdown will
be initiated.
The icon will illuminate.
EMERGENCY STOP, removal of the positive DC Supply from the Emergency Stop input initiates the following
sequence, firstly it will initiate a controlled shutdown of the Generator and prevent any attempt to restart the
Generator until the Emergency Stop push-button has been reset. Secondly it removes the positive DC supply from
both the Fuel Solenoid and Starter Solenoid.
The icon will illuminate.
NOTE:- The Emergency Stop positive signal must be present otherwise the unit will shutdown.

4.5 HIGH CURRENT SHUTDOWN ALARM
GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the pre-set trip a
warning is initiated. This warning will continue for a period of time depending upon the level of overload that the
generator is subjected to, and the configuration setting for Generator High Current in the 5200 series configuration
software.
For instance the factory default settings for Generator High Current allow for a loading of the generator to 110% for
one hour. That is to say if the generator load level exceeds the trip point by 10%, a warning alarm will occur while
the overload condition exists. If the load level does not drop to normal levels within one hour, the set is stopped,
the 5220 module displaying either shutdown alarm or electrical trip alarm depending upon module configuration.
Additionally, the Aicon will illuminate.
NOTE:- Higher overload levels will result in a faster acting shutdown condition. For instance with
the factory default configuration, an overload level twice that of the trip level ( typically 200%) will result
in a Generator High Current shutdown condition after 36 seconds.
For details of the relationship between the overload and the shutdown time, please see the Appendix
section of this manual.
4.6 ELECTRICAL TRIPS
Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the electrical trip
condition the module will de-energise the ‘Close Generator’ Output to remove the load from the generator. Once
this has occurred the module will start the Cooling timer and allow the engine to cool off-load before shutting down
the engine. The alarm must be accepted and cleared, and the fault removed to reset the module.
In the event of an electrical trip alarm the icon will illuminate.
Additionally, During the cooling timer the warning symbol is displayed followed by the flashing shutdown
symbol when the cooling timer has expired.
AUXILIARY INPUTS, if an auxiliary input has been configured as an electrical trip the appropriate LCD segment
will be displayed:-
!
GENERATOR HIGH CURRENT. If the module detects a generator output current in excess of the pre-set trip a
warning is initiated.
The Aicon will illuminate.
If this high current condition continues for an excess period of time, then the alarm is escalated to either a
shutdown or electrical trip condition (depending upon module configuration). For further details of the high current
alarm, please see High Current Shutdown Alarm.
