AUTOSTART 705 (AS705S series)
PROGRAMMABLE GENERATOR CONTROLLER
The Autostart 705 provides the control features for the
automatic or manual starting, load transfer and shutdown of
a standby diesel generator or pump. The AS705 is a micro-
processor based controller, giving full programmability of
timers, trip levels and control options, with front facia LEDs
for the indication of generator status and faults.
Key features
Automatic or manual operation, selected by rotary switch
(key-switch available as an option).
17 LED status and fault indicators, including 5 LEDs
for custom programming and labelling
RS232 communications link for engine monitoring,
control and Autostart programming from local PC
Comprehensive fault protection and alarm system:–
low oil pressure, high engine temperature, overspeed,
underspeed, charge fail, emergency stop, start fail, high
and low battery voltage, 3 programmable fault inputs.
6 programmable outputs, allowing remote signalling
and control of over 30 different functions.
Pin compatibility with Autostart 710 and Keystart 9700
ranges, allowing standardisation of panel wiring.
96 x 96mm DIN standard, front panel mounted case
Operation
Autostart's operating mode is selected by use of its
3 position front facia switch:–
Off/reset. Disables the engine and resets 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 and Manual modes. On keyswitch
versions, the key is common to all units and may be
removed in the Off and Auto positions only.
Control Outputs
The following 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 will shut down and latch
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 low generator frequency or speed.
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 fitted for high and
low battery volts, charge fail and mag. pickup fail conditions.
