Enfo IV (109050) 090303 – 1 – Class 1

The Enfo IV is an engine-monitoring device that reads and displays engine

temperature, engine RPM, and engine oil pressure as it is transmitted from the

engine ECU via the SAE J1939 CAN bus. Vehicle voltage is also displayed but is

independent of CAN operation.

The Enfo IV can be used on both 12 and 24 Volt systems. The Enfo IV uses an

automatic voltage detection system to determine the low voltage point for alarm

activation.

The Enfo IV can be connected to an external alarm and external alarm-silence

switch. High engine temperature (250° F), low oil pressure (10 PSI), or low voltage

(11.9V or 23.8V) will cause the Enfo IV to activate the external alarm.

INITIALIZATION

1. A normal initialization of the

Enfo IV will light all LED

segments to verify that all

displays are operational.

2. The Enfo IV then displays the

software revision number.

3. The Enfo IV then checks for

valid CAN communication and

checks the voltage range.
