In addition to the wiring shown in figure 16.12 it is also recommended that a
label is positioned next to the Wait To Disconnect indicator to ensure that the
operator is informed of the lamps purpose. An example Wait To Disconnect
label is shown below.

For those machines wishing to use a J1939 CAN message for communication
of the operator purge procedure completion to the machine operator. The
J1939 PGN / SPN has been provided to enable machine controller / display
integration.

* The Actual states used are dependent upon the engine range being
used.
The method of machine implementation of SPN 4332 will depend on;
• Engine range being installed i.e. 1204F or 1206F.
• Position of the Wait to Disconnect Indicator (Cab or next to battery
disconnect switch).
It is anticipated that the position of the Wait To Disconnect Indicator will affect
the way in which the indictor is required to operate. For example an indicator
within the machine cab may only want to illuminate when the ignition is OFF
but the engine ECM and DEF system is still active (for Purging). An indicator
next to the machine battery however may need to be illuminated permanently
while the engine ECM is live and not just during shutdown. For this reason
the 1204F and 1206F products offer the customer the ability to operate the
Wait To Disconnect as described in the following diagrams.
