DISPLAYS
The Engine Status Center Display (ESC)
continuously shows Engine RPM, Oil Pressure, T emperature, and System V oltage on

The Message Center is an eight charac-
ter alphanumeric display. In nor mal operation the message center will display a
logo.
If a Check Engine or Stop Engine malfunction occurs, Detroit Diesel Engines
transmit both of these messages on the
data bus , the displa y will read CHK ENG
or STOP ENG. Other Electronic Engines
may not tr ansmit these messages. To display Stop or Chec k engine messages for
these engines, connections must be made
from the engine ECM or cab indicators to
the ESC.

B-4 is a ground input dedicated to the Check Engine Warning of the ESC. T o receiv e this
message on non-DDEC engines, you must provide this input.
B-5 is ground input that will display a generic warning message A UX IN. This can be any
warning signal that you wish the operator to receive. For example on a non-DDEC
engine, provide a ground input from the STOP Engine output of the engine ECM and
change the message to read STOP ENG if y ou want the Pump Operator to receive the
STOP ENGINE Message.
B-9 is a ground output to an OEM alarm.
B-10 is a positive (12 VDC) input that allows the ESC to accumulate PT O hours.
B-11 is a positive (12 VDC) input that will tally hours as long as the ESC and this input
are active. The displa y message can be customized by the OEM to indicate its usage .
B-12 is a ground input from a tank lev el s witch to alert the operator of a low fuel condi-
tion.

MESSAGES
Alert Messages are preceded by a short
tone burst to alert the operator . The cause
for the alert is then displayed on the message center, alternating with other information.
Alert Messages:

CHK ENG Check Engine
LDMGR ON Load Management
T ANK LO W Tank Le vel
LM-LVL:x (1-8) Shed level
Alarm Messages are accompanied by a
pulsed alarm that continues until silenced
or the cause eliminated. The alarm message is displayed in the message center
and LO or HI is displayed on the appropriate display for temperature, oil and voltage alarms.

NOTES
Notes:
The engine information is “read” from the engine ECM. If some information is displayed then the ESC is functioning properly . Missing information is the result of an engine broadcast not being sent or a message header not in the
proper format. If temperature is missing chec k that the source (oil or w ater) is configured properly .
The voltage displayed is taken from the inputs at A1 and A2. It may vary from battery voltage dependent on the
voltage drops in the wiring. The alarm points can be changed by the OEM to suit the end user .
The LOW FUEL input would normally be tied to a low fuel switch in the tank. This can be part of a sending unit or
a separate switch.
The USER INPUT can be used for any purpose. It can be tied to a temperature switch on the transmission and
labelled HOT TRNS or something to that eff ect.
The AUX HRS input can be tied to an ything. An auxiliary generator or hydr aulic pump for instance. The label can
be changed and then hours on that equipment can be tracked.
