NOTE B: REFER TO THE INSTALLATION GUIDE FOR ADDITIONAL
NOTE A: THE CUSTOMER CONNECTOR BRACKET GROUND STUD MUST
HAVE A DIRECT WIRE CONNECTION TO BATTERY (-). THIS
CONNECTION CAN BE MADE AT THE STARTER (-) TERMINAL
NOTE C: MAXIMUM LENGTH OF DATA BUS (TERMINATION RESISTOR
TO TERMINATION RESISTOR) IS 40 METERS
INSTALLATION DETAILS
NOTE L: 12 VOLT BATTERY SYSTEMS MUST USE THE DC/DC CONVERTER
FOR THE EMS TO OPERATE PROPERLY. 24 VOLT SYSTEMS
SHOULD CONNECT SWITCHED BATTERY DIRECT TO PINS
1 & 2 ON THE 12 PIN EMS HARNESS CUSTOMER CONNECTOR
NOTE K: WHEN THE SHUTDOWN SWITCH IS CONNECTED TO BATTERY (-)
THE ECM DISABLES THE FUEL INJECTION SIGNAL. THIS
ACTION CAUSES THE ENGINE TO SHUTDOWN WHILE LEAVING
THE ECM POWERED TO MONITOR ENGINE DIAGNOSTICS
NOTE H: THE DEFAULT SETTING FOR THE EMS IS METRIC UNITS.
IF METRIC UNITS ARE REQUIRED NO CONNECTION IS NEEDED.
IF U.S. UNITS ARE REQUIRED, A PERMANENT CONNECTION TO
BATTERY (-) IS REQUIRED
NOTE G: ONE MAIN EMS MODULE IS REQUIRED FOR EACH DESIRED MONITORING
STATION. THE TACHOMETER AND/OR QUAD GAUGE UNITS ARE
OPTIONAL AND WILL NOT OPERATE WITHOUT CONNECTION TO
A MAIN EMS MODULE
NOTE F: PIN 22 ON THE EMS MAIN MODULE 40 PIN CONNECTOR
MUST BE CONNECTED TO BATTERY (-) FOR PROPER OPERATION
NOTE E: USE RECOMMENDED CABLE OR EQUIVALENT PER SAE J1939
SPECIFICATIONS FOR ALL J1939 DATA LINK CONNECTIONS
NOTE D: PLACE APPROPRIATE CIRCUIT PROTECTION
OTHER THAN UNDERGROUND MINING
NO ADDITIONAL CONNECTIONS ARE ALLOWED TO ANY WIRES
WITHOUT CATERPILLAR ENGINEERING APPROVAL
UNLESS OTHERWISE SPECIFIED:
ALL WIRES TO BE 16 AWG OR LARGER SAE J1128 TYPE SXL OR
EQUIVALENT. FOR TWISTED PAIR SPECIFICATION SEE SAE J1708
ELIMINATION OF ANY COMPONENTS SHOWN WILL DISABLE CERTAIN
ENGINE FEATURES. CONTACT CATERPILLAR ENGINEERING WHEN
CONSIDERING COMPONENT REMOVAL
NOTE T: USE THIS SENSOR FOR UNDERGROUND MINING APPLICATIONS ONLY
NOTE U: WHEN CHANGING OIL GRADES, THE OPERATOR MUST ENSURE THAT THE
CORRESPONDING PLUG IS INSERTED INTO THE WIRING HARNESS.
FOR MORE INFORMATION REFER TO THE OPERATION AND
MAINTENANCE MANUAL.
