NOTE G: TIMING SETTINGS: TIMING RANGE SWITCH (50 SEC);
TIMING FUNCTION SWITCH (RELEASE); TIMING ADJUSTMENT
POTENTIOMETER (1.5). WITH ABOVE SETTINGS, TDR WILL
ENERGIZE THE PLPSR WHEN THE CMS LAMP OUTPUT IS
HIGH (+BAT.) AND KEEP THE PLPSR ENERGIZED UNTIL
APPROXIMATELY 5 SECONDS AFTER THE CMS LAMP
OUTPUT GOES LOW.
NOTE H: WIRE DESIGNATION AND COLOR (TYP)
NOTE F: CUSTOMER TERMINALS 377, 378, 379, AND 380 ARE USED TO PROVIDE A
PURGE CYCLE. TERMINALS 377 AND 378 MAY BE USED TO DISABLE THE
IGNITION. THE SPARK PLUGS WILL NOT FIRE IF TERMINALS 377 AND 378
ARE NOT CONNECTED. TERMINAL 379 MAY BE USED TO CONTROL THE ECM FUEL
ACTUATOR COMMAND. THE ECM FUEL ACTUATOR COMMAND WILL BE ZERO
IF TERMINAL 379 IS CONNECTED TO -BATTERY. TERMINAL 380 MAY
BE USED TO MONITOR THE GAS SHUT OFF VALVE. WHEN THE VOLTAGE AT
TERMINAL 380 IS 0 VOLTS, THE GSOV IS NOT ENERGIZED AND SHOULD BE
CLOSED. WHEN THE VOLTAGE AT TERMINAL 380 IS +BATTERY, THE GSOV IS
ENERGIZED AND SHOULD BE OPEN.

NOTE B: THE TIMING CONTROL MODULE (TCM) WAS DESIGNED TO PROVIDE
CONTROL POWER FOR ONLY TWO DETONATION SENSORS. WHEN THE
DETONATION MIXING CONTROL (DMC) SYSTEM IS INSTALLED THE DMC
MODULE IN THE ENGINE JUNCTION BOX PROVIDES CONTROL POWER FOR THE
DETONATION SENSORS. DO NOT CONNECT INTERCONNECT HARNESS WIRING
AT TERMINALS 240 AND 242 IN THE ESS PANEL AND TERMINALS 800 AND 803 IN
THE ENGINE JUNCTION BOX WHEN THE DMC IS INSTALLED.
NOTE E: PRESSURE MODULE CALIBRATION INPUT. SEE G3600 TROUBLESHOOTING
GUIDE FOR CALIBRATION PROCEDURE.
NOTE D: TIMING STEP SWITCH INPUT (OPTIONAL). IF THE TIMING STEP
IS PROVIDED, CONNECTING TERMINAL 265 IN THE ESS PANEL
TO -BATTERY WILL CAUSE THE IGNITION TIMING STEP. THE
TIMING STEP VALUE IS PROGRAMED IN THE PERSONALITY MODULE.
NOTE C: WATER/OIL LEVEL TERMINAL BOX IS MOUNTED AT THE

NOTE A: SLAVE RELAY NO.1 (SR1), THE PRE-LUBE PRESSURE SWITCH RELAY
(PLPSR), AND THE PRE-LUBE RELAY (PLR) ARE LOCATED NEXT TO
EACH OTHER IN THE ESS PANEL. SR1 AND PLPSR HAVE 24V COILS.
PLR HAS A 12V COIL. THE PRE-LUBE WILL NOT OPERATE IF THE
PLR IS REPLACED WITH THE SR1 OR PLPSR.

NOTE G: TIMING SETTINGS: TIMING RANGE SWITCH (50 SEC);
TIMING FUNCTION SWITCH (RELEASE); TIMING ADJUSTMENT
POTENTIOMETER (1.5). WITH ABOVE SETTINGS, TDR WILL
ENERGIZE THE PLPSR WHEN THE CMS LAMP OUTPUT IS
HIGH (+BAT.) AND KEEP THE PLPSR ENERGIZED UNTIL
APPROXIMATELY 5 SECONDS AFTER THE CMS LAMP
OUTPUT GOES LOW.
NOTE H: WIRE DESIGNATION AND COLOR (TYP)
NOTE F: CUSTOMER TERMINALS 377, 378, 379, AND 380 ARE USED TO PROVIDE A
PURGE CYCLE. TERMINALS 377 AND 378 MAY BE USED TO DISABLE THE
IGNITION. THE SPARK PLUGS WILL NOT FIRE IF TERMINALS 377 AND 378
ARE NOT CONNECTED. TERMINAL 379 MAY BE USED TO CONTROL THE ECM FUEL
ACTUATOR COMMAND. THE ECM FUEL ACTUATOR COMMAND WILL BE ZERO
IF TERMINAL 379 IS CONNECTED TO -BATTERY. TERMINAL 380 MAY
BE USED TO MONITOR THE GAS SHUT OFF VALVE. WHEN THE VOLTAGE AT
TERMINAL 380 IS 0 VOLTS, THE GSOV IS NOT ENERGIZED AND SHOULD BE
CLOSED. WHEN THE VOLTAGE AT TERMINAL 380 IS +BATTERY, THE GSOV IS
ENERGIZED AND SHOULD BE OPEN.

NOTE B: THE TIMING CONTROL MODULE (TCM) WAS DESIGNED TO PROVIDE
CONTROL POWER FOR ONLY TWO DETONATION SENSORS. WHEN THE
DETONATION MIXING CONTROL (DMC) SYSTEM IS INSTALLED THE DMC
MODULE IN THE ENGINE JUNCTION BOX PROVIDES CONTROL POWER FOR THE
DETONATION SENSORS. DO NOT CONNECT INTERCONNECT HARNESS WIRING
AT TERMINALS 240 AND 242 IN THE ESS PANEL AND TERMINALS 800 AND 803 IN
THE ENGINE JUNCTION BOX WHEN THE DMC IS INSTALLED.
NOTE E: PRESSURE MODULE CALIBRATION INPUT. SEE G3600 TROUBLESHOOTING
GUIDE FOR CALIBRATION PROCEDURE.
NOTE D: TIMING STEP SWITCH INPUT (OPTIONAL). IF THE TIMING STEP
IS PROVIDED, CONNECTING TERMINAL 265 IN THE ESS PANEL
TO -BATTERY WILL CAUSE THE IGNITION TIMING STEP. THE
TIMING STEP VALUE IS PROGRAMED IN THE PERSONALITY MODULE.
NOTE C: WATER/OIL LEVEL TERMINAL BOX IS MOUNTED AT THE
RIGHT FRONT ON ALL G3600 ENGINES AND INCLUDES TERMINALS FOR
CONNECTING OPTIONAL WATER AND/OR OIL LEVEL SWITCH. NOTE - LOW
