15.5 Auxiliary Pressure Sensor
15.5.1 Auxiliary Pressure Sensor Operation
The auxiliary pressure sensor feature is provided so the engine can monitor
any external pressure and provide that pressure information via the J1939
CAN data link. The ECM can also protect the system in the event of
excessive pressure by taking any action configured within the engine
monitoring system as shown below in table 15.11

15.5.2 Auxiliary Pressure Sensor Configuration
The default condition for this sensor option is ‘uninstalled’. Before any
configuration of the monitoring system for the pressure sensor can take place
this status must be changed using the service tool to ‘Installed’. This option
can be found on the main configuration screen within the service tool. Once
‘Installed’ the following parameters can be configured;
• Time delay or ‘debounce’ time before the ECM acts upon the inputted
pressure signal.
• The Aux pressure sensor severity level set points can be set.
Table 15.12 Provides details on each of the configurable elements, there
configurable range and default settings.

15.5.3 Auxiliary pressure Sensor Installation
The PERKINSauxiliary pressure sensor part number must be used in order to
accurately measure pressure. Third party sensors will not be compatible with
the hardware and software. The auxiliary pressure sensor is an analogue
sensor with an operating range of 0 to 3150kPa (0 to 442 psi).
Note: Do not splice the sensor signal wire for input to third party
devices.
