D escription
The AS705S provides fully automatic control, fault
monitoring and shutdown of a standby generator,
pump or engine driven application.
Features include:• Automatic or manual control, keyswitch or
rotary switch selectable
• Status and fault indication by 17 LEDs. 12 have
preset labelling, 5 may be custom programmed
and labelled.
• Wide range power supply, 5 to 40 VDC.
• Automatic, timed control of generator contactor.
• Electrical connection by two-part, screw terminal blocks.
• Tamper proof settings. Timers, I/O and control options
are set using a PC serial link and free of charge software.
• Compact, front of panel mounting
Application
The Autostart series may be used in any unmanned
application where automatic engine starting and stopping is
required. The AS705’s control, measurement

The AS705 is programmed using PC software model AS7CK,
available for free of charge website download. During setup,
AS705 and PC are connected by local serial link (using the
accessories listed left). Over 50 programmable functions allow
custom set-up for your application:Timers: start delay, preheat, crank, crank rest, no. of start
attempts, alarm override, engine warmup, speed signal,
(mains AC) restoration, cooldown, (fuel) energised to stop.
Inputs: input 1 – 5 configuration (open/close/+ve/-ve); input
3 – 5 actions (shutdown, warning, indication, load release,
lamp test, manual restore, test, alarm mute, load reset)
Outputs: 6 outputs, each set for one of 40 signalling and
control options, e.g. preheat, energised to stop fuel,
engine running, muteable alarm, individual faults, etc.
Generator: trip Hz/RPM levels and response for crank release,
underspeed, overspeed, speed overshoot on start.
DC: high and low battery voltage warning, charge fail settings
(charge alternator WL or battery charger), WL crank release.
LEDs: allows programming of the LED indicators (including
the 5 with custom message windows).
See document mi5265 for a full list of program options.
Software AS7CK also features real time monitoring and display
of engine parameters – see document mi5266 for full details.
