Simplified System. The electrical
system has been redesigned to utilize
three electronic control modules (ECM)
on the tractor instead of four. The rear-
powered scraper now has two ECMs
rather than three.
Air Filter Restrictor Indicator.
Electronic control module (ECM)
monitors air filter restriction and sends
a warning message to the electronic
monitoring system (EMS) to alert the
operator if the restriction exceeds the
allowable limit.
Automatic Ether Injection. The ECM
activates the ether injection system
during engine cranking to enhance cold
weather starting.
Automatic Altitude Compensation.
At high altitudes the system automatically
de-rates fuel delivery as a function of
barometric pressure sensed by the
system’s atmospheric pressure sensor.
Low Battery Elevated Idle. ECM
automatically compensates for low
alternator output at low idle by raising
the rpm for brief intervals to keep the
batteries fully charged.
Improved Serviceability. Combined
monitoring systems, easy access
diagnostics and more durable components
make routine maintenance and servicing
simple and fast.
Combined EMS Monitoring. The
Electronic Monitoring System
(EMS III) on the 627G is designed to
monitor both the tractor and scraper
status and access fault codes from one
location instead of two. Both the tractor
and powered scraper use the same
controller for parts commonality
and easier servicing.
Easy Access Diagnostics. Diagnostic
codes are accessible through the EMS
main display module, via the Electronic
Technician (Cat ET). This offers a head
start on problem solving, with a radio
call often providing the service technician
with the knowledge of which tools,
troubleshooting guides, and possibly
even replacement parts to bring to
the machine.
Greater Reliability. The Caterpillar EUI
system has fewer moving parts than
mechanical unit injection and requires
few adjustments. ECM communicates
with the monitoring system (EMS) to
warn the operator when problems arise,
preventing major damage from occurring.
Maintenance. EUI engines have
virtually no mechanically controlled
parts to wear or adjust. These have
been replaced by electronic controls,
reducing maintenance costs and
increasing machine availability.
Fuel Economy. Electronic controls yield
a fuel savings by optimizing the timing
setting for varying conditions. The ECM
matches timing to the load on the engine,
engine speed and temperature.
Product Link Ready. Product Link is a
wireless system that allows the customer
to track machine data such as location,
service meter hours as well as machine
health information. The system has the
capability to automatically issue alerts
when the machine is being operated
beyond owner defined time and
location limits.
Reduced Exhaust Smoke. The ECM
reads electronic sensors to determine
the optimum fuel/air ratio, then precisely
controls fuel during cranking, starting
and acceleration to reduce smoke.
The ECM system is faster and more
efficient than mechanically controlling
the governor rack position.
