Introduction
This document provides general information on LOFA™ MC704 panel operation and troubleshooting. MC704
panels are a flexible platform for diesel engine control, monitoring and protection, 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 and one additional
contact closure input. The microprocessor-based solid-state design uses high-power semiconductors instead of
outdated electromechanical relays to ensure reliable high-current switching.
The MC704 panels are offered in two versions. The MC704HP has a built-in tamperproof LED hourmeter while
the reduced cost MC704LCP eliminates the hourmeter. Both versions can be factory configured with specific
preheat and afterglow requirements. If preheat is not required, this output can function as an alarm.
All standard panels feature a 12-inch wiring harness terminating into a sealed weather-proof plug. This
robust universal wiring connection performs well in harsh environments and allows interchanging a number
of different panels and harnesses. This design allows for simplified installation as well as a flexible means to
incorporate custom plug-and-play engine wiring harnesses and standard harness extensions.
Note:
The engine harness is not included with the panel
.
A number of standard engine harnesses are available, or Cattron can develop a custom harness for
your exact needs.
Generic harnesses in various lengths are available for field customization.
