The AHD 414 Start/Stop Diesel Monitoring Unit is a compact unit designed for starting, stopping and monitoring diesel engines. A number of individual functions allow adaptation to various situations. The device is designed for panel installation and constructed for auxiliary diesel generator sets and emergency or smaller main engines. Frontside keys allow simple and comfortable operation locally. Separate inputs exist for remote control (start and stop from the bridge).
The engine is started directly from the device or remotely via the remote start input. All start release criteria must be met before the starter is activated. Several start attempts in a row can be made. Start time, pause interval and the number of start attempts can be made for this purpose. After the ignition speed has been reached, the starter is released and the system switches to the monitoring mode “Engine Running.” All necessary monitors, including engine speed, are monitored during operation. Threshold violations are alerted acoustically and optically and depending on the parameterization, the engine is also stopped. Overspeed always leads to an immediate stop
