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. 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.

This mode is activated by pressing the Auto button confirms this action.
The start sequence is initiated when the remote start input is activated. To allow for 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 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 output Generator Running is activated if it has been configured. On removal of the Remote Start signal the Stop delay timer is initiated. Once this timer has expired the Fuel Solenoid is de-energised, 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.

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. icon will illuminate. The 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. icon will illuminate. The 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

CONNECTION DETAILS
703 remote start module Remote start signal ( switched to battery -ve) Load transfer output Diode Engine running output Battery +ve
DC relay
7.2
DESCRIPTION
With the 703 in AUTO mode, applying the remote start signal will begin the start delay timer, after which, the engine will be called upon to start. Upon activation of the Engine Running output, the DC relay will close, switching the remote start signal through its contacts. This switched signal becomes the Load Transfer output, which can be used to drive a DC load-switching device or further slave relay if required. When the remote start signal is removed, this also removes the Load Transfer output (opening the contractor) and begins the 703s Stop Delay timer. This acts as a cooling timer to allow the set to cool off load. When the Stop Delay timer expires, the set will be stopped. NOTE:- The diode acts to stop any voltage from the 703s remote start input circuitry being fed through the DC relay.
