Yanmar ACP200 - Auto Stop/Start System

ACP200 - Auto Start/Stop System

ACP200This 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.

Feature
  • Sturdy weatherproof cabinet
  • Various input/output stop methods
  • Inbuilt engine protection
  • Supplied fully wired on new engines or gensets
  • Locally designed and built
  • Full engine protection
  • 7 day / 24hr programmable timer
  • Manual override
  • Digital hour meter
  • Pump loss of prime switch
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 example

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.
