Table 15.8 Auxiliary Temperature Sensor Monitoring
When enabled the engine ECM is able to respond with either an engine
derate or shut down upon receiving a temperature value, which is above a
pre-defined threshold.
15.4.2 Auxiliary Temperature Sensor Configuration
The default condition for this sensor option is ‘uninstalled’. Before any
configuration of the monitoring system for the temperature 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
temperature signal.
• The Aux Temperature sensor severity level set points can be set.
Table 15.9 Provides details on each of the configurable elements, their
configurable range and default settings.

15.4.3 Auxiliary temperature Sensor Installation
The Perkins auxiliary temperature sensor part number must be used in order
to accurately measure temperature. Third party sensors will not be
compatible with the hardware and software. The auxiliary temperature sensor
is a 0-5V passive analogue sensor with an operating range of –30 to 140°C (-
22 to 248°F). The auxiliary temperature sensor is shown in figure 15.7 and
table 15.10 indicates the components required to connect to the sensor.
