Murphy Autostart 730 AS730 User manual

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
•Monitoring, display and programmable fault trips for
generator speed/frequency, 3 phase voltage and 3
phase current with IDMT response.
•Comprehensive automatic fault protection system:–
up to 5 programmable fault inputs, overspeed, charge
fail, emergency stop, and high and low battery volts
•6 programmable outputs, each with over 40 different
function (or ‘action’) types.
Operation
Control of the Autostart is via 4 front facia keys:-
ON/MODE Turns on the Autostart and allows selection
of Auto or Manual modes.
PAGE Used to scroll through measured generator
parameters, such as 3 phase voltage
and current, engine oil pressure and
temperature, hours run and battery voltage.
SELECT Used in the programming of Autostart
OFF Turns the Autostart off, disabling the
generator and resetting any fault condition.
These keys are also labelled with symbols,
used in the programming of each Autostart (see overleaf).
Two front facia LEDs indicate the selected operating mode:
green for Auto, amber for Manual.
Control Outputs
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.
Fault Protection and Alarm System
The Autostart 730 has a comprehensive fault detection,
warning and automatic response system:-
•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.
•Three programmable inputs for use with remote fault
switches. The inputs can be set to give a warning only,
generator load release or shutdown response.
•User set trip levels and response for generator speed/
frequency, 3 phase voltage and 3 phase current.

In order to consistently bring you the highest quality,
full featured products, we reserve the right to change our
specifications and designs at any time.

•Additional fault alarms:-
Warnings: low and high battery voltage, charge fail
and magnetic pickup fault
Shutdowns: emergency stop, start fail and system fail.
Programmable functions
The AS730 has all the programmable functions found on the
Autostart 710 – timers, alarm configurations, trip levels and
programmable inputs/outputs – plus the following:-
•Generator under voltage trip, under voltage reset,
over voltage trip levels.
•Generator full load current, IDMT response constant
and instant trip level.
The Autostart may be programmed by use of the front facia
keys: to prevent end-user tampering, entry to program mode
is restricted by use of a code number.
The addition of a small RS232 interface allows the AS730 to
be connected to a remote (IBM compatible) computer, either
directly or over a modem link; Murphy Modex communication
software allows a PC operator to program, monitor and
control the Autostart from a remote location.
