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
·
Automatic, Manual and Program modes, selected by
front facia push button keys
·
·
32 character, back-lit liquid crystal display (LCD)
Fully programmable generator control options, timers,
inputs, outputs and fault protections
Product Specification

designed for use with 5 Amp CT's
primary ratings 10 to 5000 Amps
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.

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.
