DESCRIPTION
The EM500 Series is a very flexible platform for diesel engine control and monitoring, featuring LOFA’s powerful First Fault Diagnostics (FFD). After pinpointing the initial failure, FFD stores it in memory and alerts the end user via a single bright LED. FFD monitors battery charge, low oil pressure, high temperature, two additional engine faults and diagnostic blink code. The microprocessor-based solid-state design uses high power semiconductors instead of outdated electromechanical relays to ensure reliable and reliable high current switching.
The integral throttle control works with most electronic engines by offering programmable choice of voltage, Pulse Width Modulation (PWM) or CANbus throttle control. A single momentary toggle switch adjusts the throttle with programmable throttle ramp time and engine speed limits. When teamed with LOFA’s MSS200 Auto-Start Module, the EM500's flexible throttle control makes an ideal auto-start control system. Alternately, the EM500 can be programmed to operate in
dual-speed mode via a toggle switch or external input.
Standard VDO Cockpit International analog gauges display current operating parameters reported by the ECU, including RPM, engine temperature and oil pressure. Additional gauges can be installed for engine oil temperature or other ECU parameters. With the addition of the optional Diagnostic Program Gauge (DPG), virtually any SAE J1939 parameter or diagnostic code can be monitored. The Diagnostic Program Gauge (DPG) features a backlit LCD display with three push buttons in a 2” gauge. Additionally, three bright LEDs indicate Preheat, Service Due and Auxiliary input. The LCD is clearly readable in both bright sunlight as well as total darkness. The DPG allows each system to be field programmed to suit the customer's unique requirements. After programming, the DPG can be removed in
cost sensitive applications.
Some of the EM500 Series programmable features include:
• Engine brand (Caterpillar, Deutz, John Deere, Perkins, etc.)
• Throttle type (Voltage, PWM or CANbus)
• High idle speed
• Throttle ramp time
• Charge indication mode (lamp input or system voltage)
The standard system terminates to a sealed Deutsch weatherproof plug. This wiring solution offers a robust connection that performs well in harsh environments and allows simplified installation. The design allows efficiently installing custom plug-and-play engine wiring harnesses as well as standard harness extensions.
