AUTOSTART 710 (AS710S) series
PROGRAMMABLE GENERATOR CONTROLLER
The Autostart 710 provides the control features needed for
the automatic start, load transfer and shutdown of a
standby generator or pump. Microprocessor technology
allows the Autostart 710 to be programmed for use in a
wide range of engine and generator control applications.
Key features
• Automatic or manual operation, selected by key-switch
or optional rotary switch.
• 32 character, back-lit liquid crystal display (LCD), showing
operating mode, system status, timer information,
generator RPM/Hz., oil pressure and engine temperature
• Full programmability of engine control options, timers,
trip levels, fault options and input/output configurations
• Comprehensive fault protection and alarm system:-
low oil pressure and high engine temperature alarms
(using analogue or switch sensors), engine overspeed
and underspeed, emergency stop, start fail, charge fail,
high and low battery voltage, 3 programmable fault inputs.
• 6 programmable outputs, each configurable to one
of over 30 function types.
• Pin compatibility with Keystart 9700 range, allowing
standardisation of panel wiring
Operation
The AS710’s operating mode is selected by use of a 3
position switch:–
Off/reset. Removes power from the unit, disabling
the engine and resetting a latched fault condition.
Automatic start-up, load transfer and return to
standby in response to a mains fail or remote
start condition, with full fault protection.
Manual start and stop of the generator, either
immediately on selecting manual mode or by
use of remote push button switches.
Green and amber LEDs around the switch indicate the
selection of Auto or Manual modes. On keyswitch versions,
the key is common to all units and is removable in the Off
and Auto positions only.
Control Outputs
The following outputs are provided:-
• Single pole, switched +ve relay outputs for the control
of engine fuel and starter motor circuits.
• Switched +ve outputs for signalling auto and manual
modes, plus a –ve DC output for Off/reset.
• 6 function programmable outputs (see overleaf).
Fault Protection and Alarm System
In Auto or Manual modes, Autostart shuts down and latches
out the generator on detection of low oil pressure, high engine
temperature, overspeed, start fail or emergency stop faults.
The Autostart may also be set up to shut down the generator
on a low generator frequency or speed condition.
3 additional inputs may be used with remote fault switches
(giving a ‘shutdown’ or ‘warning’ response), or as control
inputs with remote contacts or panel switches (see overleaf).
Non-latching, 'warning only' alarms are provided for high and
low battery volts, charge fail and mag. pickup fail conditions.
