SAE J1939 Display Units for Off-Highway Industrial Engines

The  Enginemonitor displays by B-Plus are expansion tools, especially for industrial engines with SAE J1939 interfaces. They enable users to retrieve information from mobile machines and communicate commands directly.

Thanks to their robust housings and protection level, the devices can operate directly in the cab and the outdoor area of mobile machines. Due to various device versions, the product range covers multiple use cases and customer needs. Due to the standardized SAE J1939 communication and some engine-manufacturer-specific extensions, the Enginemonitor products meet the demands of the most common industrial engines such as CAT, Cummins, Deutz, FPT/Iveco, Hatz Diesel, Perkins, MAN, Scania, Volvo Penta, etc.

The product portfolio comprises three device types:

• Enginemonitormini is a basic version with fixed display values of selected engine data.
• Enginemonitorplus with flexible display values and operating options for speed and exhaust gas after-treatment of an industrial engine - adjustable directly on display.
• Enginemonitormaxi with adjustable display values and operating options as well as additional inputs and outputs for non-CAN-capable sensors/actuators - adjustable via the PC tool.

Enginemonitormini

The Enginemonitormini represents the basic version of the product line and offers a clear overview of standard messages according to the SAE J1939 standard. It is a display and monitoring device for industrial engines with a CAN Bus interface. Three pages display numerous CAN messages transmitted from the engine, such as engine speed, engine oil pressure, battery voltage, etc. The integrated fault diagnosis on page four allows the discovery of possible errors in the engine, e.g., wire break of the speed sensor, etc. Customers can choose between three basic units with different display sizes and mounting dimensions and frosted and clear glass. The variant provides navigation via backlit navigation keys with tactile feedback.

Enginemonitorplus

This variant is fully configurable and based on the same display types as the Enginemonitormini. Multi-language, maintenance reminders, a configuration directly via the display without a PC, and an intuitive operating concept are some product features. In addition, the display supports all common SAE J1939 messages. The motor data are displayed clearly on three pages; the user can choose several layout options. Different values change via buttons or time-based in the one-quadrant-layout. In the multi-quadrant-layout, four values are shown simultaneously. Furthermore, the information presented in a row view is available.

Enginemonitormaxi

The Enginemonitormaxi is suited to a large number of different application environments. It supports SAE J1939 electronic engines, including Tier4 final and stage V engine parameters, and supports TSC 1 messaging allowing speed control message transmission per CAN. The basic device is the E050 from DSE. The display is fully configurable using license-free PC software, enabling users to set individual parameters for all pages and CAN signals. The display icons are adjustable for each signal. In addition, customers can add their company branding to the display's start-up screen and select from a light and dark background when the module is in use. The Enginemonitormaxi has four additional configurable inputs (digital, current, voltage, and resistance), e.g., for connection of analog fill level sensors and three outputs for external relays, LEDs, and audible buzzers.

SAE J1939 Starter Kit And Network Simulator

The SAE J1939 starter kit allows you to monitor, simulate, and record any PGN as defined in the SAE J1939-71 Standard but also including diagnostic messages according to SAE J1939-73.

The starter kit was not designed to simulate specific diesel engines, but if you enter all PGNs that are being used, you can design and simulate any diesel engine.
