This system is designed
to be flexible enough to operate with most applications. It can
be used as a "demand start" for generators, be controlled by an
"irrigation" controller, programmed for multiple starts or simply stopped or started by float or pressure
switches.
It has inbuilt engine protection to guard against low oil, high
water temperature, low radiator level (TNE only) and fan belt
failure. |

Operation
There are 3 methods of starting an engine with this system:
via a
no-voltage, normally open circuit being closed, or
via the programming
manually
There are then 4 methods of stopping the engine:
by opening
the no-voltage circuit,
via the programming
via the
auxillary, normally open circuit which can be used with a pressure
gauge, float switch etc.
manually |

Application Examples for ACP200
When deciding to use an auto stop/start controller it is important
to consider exactly what 'events' or 'criteria' will trigger a start and
stop signal. Having decided this it is then important to consider what
switches, switch gauges or signalling devices are required to provide this
signal. The controller operates on the closing and opening of 'NO VOLTAGE'
circuits, ie. the simple bridging and disconnecting of two terminals.
Two examples of application are:
A bore
pump located away from a water tank supplying stock water
A start could be triggered by the time clock on a daily basis to run for,
say, 3 hours.
A stop could be triggered either by the time clock after three hours have
expired, or by fitting a ball valve at the outlet of the pump line which
shuts off the flow when the tank is full. In this case a pump high pressure
cut out switch is fitted in the delivery side of the pump line at
the pump which stops the engine when the pressure reaches a pre-determined
level. Next day it all starts again.
A
generator or pump lives in a shed close to the homestead and needs to be
started from the house
A simple on/off switch can be fitted in the normally open, no voltage
circuit. When the switch is turned on the engine will start and when the
switch is turned off the engine will stop.
While it is possible to achieve almost any scenario with the ACP200, it
does require some prior planning and preparation. A short discussion with
your Yanmar salesperson will usually be enough to crystallize your
requirements. |
