SPRING-DISC 4243477 - Caterpillar

"Engine Running Output"
Output 2, output 3, or output 4 is available for the connection of an engine running output relay that is used to prevent engagement of the starter while the engine is running. The "Engine Running Output" can be programmed to J1/P1:10, to J1/P1:12 or to J1/P1:13. The "Engine Running Output" comes on when the engine is running. The "Engine Running Output" turns off when the engine rpm is 0. The relay is normally closed so cranking can be achieved immediately at powerup. During cranking, the ECM energizes the "Engine Running Output" once engine low idle rpm has been achieved. The relay is de-energized when the engine speed falls by 100 rpm below the programmed low idle. The programmed low idle range is 600 rpm to 750 rpm.

Output 2, output 3 or output 4 is available for the connection of an engine shutdown output relay that is used to shut down the vehicle electrical system after the idle timer has expired. The "Engine Shutdown Output" can be programmed to J1/P1:10, to J1/P1:12 or to J1/P1:13. The "Engine Shutdown Output" comes on after the engine runs for more than three seconds. The "Engine Shutdown Output" turns off when the engine rpm is at least 100 rpm below the low idle rpm for more than three seconds.

"J1/P1:13"     "None"    "Auxiliary Brake"
The auxiliary brake output is for use with a BrakeSaver or other aftermarket braking devices. Output 3 is available for the connection of an auxiliary brake relay. This parameter ("Auxiliary Brake") must be programmed to J1/P1:12. Operation of the auxiliary brake and the relay is inhibited during undesirable engine operating conditions. The time period of fueling the engine is an undesirable engine operating condition.

"J1/P1:12"     "None"    "Starting Aid Output"
Output 2, output 3 or output 4 is available for the connection of the starting aid relay or the starting aid solenoid. If a starting aid switch is not used, the starting aid output will turn on automatically when operating conditions require the use of a starting aid. If the "Starting Aid On/Off Switch" parameter is programmed and a switch connected to the corresponding switch input, the starting aid output will not function when the switch is in the OFF position.

The air inlet shutoff is available for certain engine ratings that operate in areas with large amounts of combustible gases. The air inlet shutoff will protect the engine from an engine overspeed when these gases are present. If this option is installed, the "Air Inlet Shutoff Relay Control" cannot be turned off. J1/P1:62 must be connected to the +Battery in order for the air inlet shutoff to operate. If a neutral switch is installed in the vehicle, the neutral switch must be connected to J1/P1:62. The air inlet shutoff will only operate
