1 DESCRIPTION OF OPERATION
MODE
To initiate a start sequence in MANUAL, press the pushbutton, and the start sequence is initiated.
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.
After the above delay the Fuel Solenoid is energised, then the Starter Motor is engaged.
The engine is cranked for a 10 second period. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for a 10 second period. Should this sequence continue beyond the 3 starting attempts, the start sequence will be terminated and Fail to Start will be illuminated. fault
When the engine fires, the starter motor is disengaged and locked out at 20 Hz measured from the
Alternator output. 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 (which is fixed at 12 seconds), 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, at which point the load will be transferred to the generator.
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 de-energises the FUEL SOLENOID, bringing the generator to a stop.
NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can not be changed.

1.2 AUTOMATIC MODE OF OPERATION
This mode is activated by pressing the confirms this action.
pushbutton. An LED indicator beside the button
Whether the start sequence is initiated by mains (utility) failure or by remote start input, the following 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 10 second period. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for a 10 second rest period. Should this sequence continue beyond the 3 starting attempts, the start sequence will be terminated and
Fail to Start fault will be illuminated.
When the engine fires, the starter motor is disengaged and locked out at 20 Hz measured from the
Alternator output. 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 the remote start is being used and has been configured to Remote start is on load, or the mains has failed, the load will be transferred to the generator.
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 is transferred back to the mains (utility). 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.
If the mains should fail (or a Remote Start signal is re-activated) whilst the generator is Cooling down, the load will be immediately transferred to the generator.
Should the mains supply fall outside limits again (or the Remote Start signal be re-activated) during the cooling down period, the set will return on load.
NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can not be changed.

1.3 WARNINGS
Warnings are used to warn the operator of an impending fault
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. (Either 8 Volts or 16 Volts depending on the configuration of Nominal DC Voltage).
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated when the input is active
1.4 SHUTDOWNS
Shutdowns are latching and stop the Generator. The alarm must be cleared, and the fault removed to reset the module. In the event of a shutdown the appropriate icon will be illuminated
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.
NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can not be changed.
FAIL TO START, if the engine does not fire after the pre-set 3 attempts at starting, a shutdown will be initiated.
The icon will illuminate.
LOW OIL PRESSURE, if the module detects that the engine oil pressure has fallen below the low oil pressure switch after the Safety On timer has expired, a shutdown will occur.
The icon will illuminate.
HIGH ENGINE TEMPERATURE if the module detects that the engine coolant temperature has exceeded the high engine temperature switch after the Safety On timer has expired, a shutdown will occur.
The icon will illuminate.
OVERSPEED, if the engine speed exceeds the pre-set trip (14% above the nominal frequency) a shutdown is initiated. Overspeed is not delayed, it is an immediate shutdown.
The icon will illuminate.
NOTE:- During the start-up sequence the overspeed trip level is extended to 24% above the normal frequency for the duration of the saftey timer to allow an extra trip level margin. This is used to prevent nuisance tripping on start-up.
UNDERSPEED, if the engine speed falls below the pre-set trip (20% of the nominal frequency) after the Safety On timer has expired, a shutdown is initiated.
The icon will illuminate.
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated when the input is active

♦ With the unit in Stop
mode, Configuration Mode is selected by operation of a small switch on the rear, left-hand edge of the PCB. This is partially hidden to prevent accidental operation.
Normal
Configuration
Configuration Mode is selected, the ‘Auto’ LED will commence rapid flashing, and all normal operation is suspended.
♦ The Stop
pushbutton can be used to select the LED ‘code’ that corresponds to the required function. The 5 left-hand LED’s will form the code. See configuration table over leaf.
♦ The
pushbutton will allow the user to change the associated value. The 3 righthand LED’s inform the user of the current setting for the chosen function. See configuration table over leaf.
♦ When the required parameters are displayed, pressing the Auto
button will save the new setting, and the process is repeated for each function change.
♦ When configuration is complete, the Configuration Mode Selector Switch should be returned to the ‘Normal’ position.

6 SOLID STATE OUTPUTS
DSE’s utilisation of Solid State Outputs gives many advantages, the main points being:
♦ No Moving Parts
♦ Fully Overload / Short Circuit Protected.
♦ Smaller dimensions hence lighter, thinner and cheaper than conventional relays.
♦ Less power required making them far more reliable.
The main difference from conventional outputs is that solid state outputs switch to negative (–ve) when active. This type of output is normally used with an automotive or plug in relay.

NOTE:- The Close Mains Relay should be NORMALLY CLOSED when de-energised for fail safe reasons. Should the DC supply fail the mains will always be available. The output from the
DSE solid state output when energised will OPEN the relay therefore isolating the mains supply.
