10.2.3 User Defined Shutdown Switch (Remote Shutdown)
10.2.3.1 User defined Shutdown Switch Operation
Remote stop is intended to provide a convenient method of stopping the
engine. It is not designed to be fail safe and so should not be used to assure
the protection of either personnel or equipment
Remote stop buttons may be used on large machines, which can be operated
from ground level and where the operator wants to stop the machine without
climbing into the cab.
There are a number of variations on remote stop button circuits. The engine
uses a single normally open contact, which must be closed to stop the engine.
The remote stop button will function as follows:
When the switched is closed (or if a button is stopped for longer than
150msec), then the engine will stop. The ECM will remain ON, so it will
continue to communicate over J1939 and with the service tool. Note however
that it will continue to draw power from the battery so if it is left in this state it
will eventually result in a flat battery.
The engine may be restarted by opening the switch and activating the starter
motor.
The red “mushroom” emergency stop buttons must not be used for remote
stop functions as they may be mistaken for emergency stop buttons as
described above.
10.2.3.2 User Defined Shutdown Switch Configuration
The user defined shutdown feature must be enabled within the engine ECM
using the service tool.
10.2.3.3 User Defined Shutdown Switch Installation
A single switch to ground input on pin 68 of the ECM J1 Connector (Several
stop buttons can therefore be connected in parallel).
