【発明の詳細な説明】
本発明は主として舶用機関の制御に用いられる制御装置
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device mainly used for controlling a marine engine.
一般に舶用機関及びこれに装備されるクラッチはいずれ

利で、そのためこの制御装置は一台で機関等の多機種に
対応しうるように構成されている。In general, marine engines and the clutches installed on them are manufactured in small quantities in a wide variety of models, so it is economically disadvantageous to manufacture devices for controlling these for each type of engine. The device is configured so that one device can be used with many types of engines.
この種制御装置は具体的には通常第１図に示すように、

る。Specifically, this type of control device usually has the following features as shown in FIG.
It consists of a device main body 2 which is equipped with a CPU 1 inside, a relay wire harness 3, and an engine side wire harness 4. Conventionally, as a system that supports many types of engines, etc., the model is stored in the ROM 5 in the device main body 2. A plurality of different sets of control data or a plurality of control programs are stored for each model, and a selection signal is input to the CPU 1 by opening/closing the switch 6 for model selection, and the required control data and control program are input from the ROM 5. There is one that allows it to be read.
しかし、この制御装置は、機関とは別個に製作され、犠

水性が損われるという欠点もあった。However, since this control device is manufactured separately from the engine and is combined with the engine for the first time at the sacrifice site, the conventional method described above requires operating the model selection switch when installing it on the hull. If you have to do this, which is time-consuming and troublesome, there is a huge risk of making a mistake in switch operation. Furthermore, the main body of the control device must have sufficient waterproofness to avoid being affected by wave spray, but there is also the drawback that if a model selection switch is placed on the surface of the main body, the waterproofness will be impaired.
