Datasheets LOFA Products

First Fault Diagnostics

Engine monitoring, protection, and diagnostics via FFD for battery charge, low oil pressure, high temperature, and two auxiliary shutdown inputs for customer-defined faults

First Fault Diagnostics Alerts

After pin pointing the initial failure, stores the shutdown in memory and alerts the end user via a single bright LED, of the exact cause of failure


Ultra bright First-Fault Diagnostics LED display - highly visible in direct sunlight

Automatic Shutdown

Automatic shutdown override simplifies engine starting by eliminating the need to push a button

Solid-State Design

A microprocessor-based, solid-state design that uses reliable, high-power semiconductors rather than outdated electro-mechanical relays


Standard gauge configuration is with oil pressure, temperature, voltmeter, hour meter, tachometer, and two gauge openings for optional gauges

Key Switch

Heavy-duty IP64 water-resistant key switch with a mechanical restart lockout

Frequency Input

Frequency input compatible with either alternator frequency terminal, proximity switch, or magnetic pickup (wiring kit required)


Heavy-duty powder-coated Aluflex™ aluminum enclosure with integrated isolation mounting designed to withstand the most extreme industrial applications for customers needing two to seven gauges

Solenoid Output
