ENFOIII harness connection to the apparatus is achieved by the use of a Deutsch four (4)
pin socket connector.
Deutsch DT06-4S 4 socket connector
Cavity Description ESC
A-1 Ignition Power 12V In Power for the ENFOIII
A-2 System Ground Ground in Ground for the ENFOIII
A-3 Data Link + J1587 in Data line positive
A-4 Data Link - J1587 in Data Line negative
A-1 circuit
A-2 circuit
These are the power and ground inputs for ENFOIII operation and they also
provide system voltage information to the ENFOIII for display.
ESC Data
A-3 circuit
A-4 circuit
Engine information is received electronically on the J-1587 data bus.
The ENFO III continuously shows Engine RPM, Oil Pressure, Temperature, and System
Voltage on four seven segment LED displays.
The ENFO III will determine whether to source coolant or oil for temperature automatically.
The mode of operation (English or Metric) is indicated by an LED illuminated next to the
current mode.If a low oil pressure situation occurs (<10 PSI), the oil pressure display will
alternate between the current oil pressure and
LO LO LO LO LO
and the alarm will activate.
If a high temperature condition develops (235 deg. F), the engine temperature display will
toggle between the temperature value and
HI HI HI HI HI
and the alarm will activate.
A low voltage condition (<11.9 VDC) results in an audible alarm and the voltmeter alternat-
ing between the actual voltage and
LO LO LO LO LO
.
