AUTOSTART 730 (AS730 series)  
PROGRAMMABLE GENERATOR CONTROLLER  
The Autostart 730 provides for the fully automatic or manual  
control of a standby generator. The unit has similar control  
and instrumentation features to the Autostart 710, but with  
the addition of 3 phase generator voltage and current  
measurement, display and fault tripping.  
Key features

Control Outputs  
Outputs:  
(all ratings for resistive load)  
Dedicated relay outputs are used for engine fuel and starter  
motor control. The AS730 has 6 programmable outputs,  
each of which may be set up for use as one of over 40  
function types, e.g. preheat (4 types), engine running,  
individual faults (e.g. overspeed, overcurrent, start fail,  
oil pressure, etc.), energised to stop fuel, etc.  
Start and fuel relays  
SPNO contacts (switched +ve)

The Autostart 730 has a comprehensive fault detection,  
warning and automatic response system:-  
(default setting: Gen. Contactor)  
5 A max. @ 240 V AC  
·
Dedicated inputs for low oil pressure and high engine  
temperature sensors, either switch or analogue type.  
The use of analogue sensors allows for pre-warning as  
well as shutdown alarms, and real-time display of oil  
pressure and engine temperature.
