14.2.1.2 Coolant Temperature Monitoring Mode Configuration
The high engine coolant temperature threshold settings are available for
adjustment within Perkins EST for all monitoring system severity levels.
There are however upper and lower limits outside of which the thresholds
cannot be set these are shown below
Monitoring Mode
Level
Trip Threshold Min
Trip Threshold Max
Severity L1 85°C 109°C
Severity L2 86°C 111°C
Severity L3 87°C 114°C

14.2.1.3 Coolant Temperature Monitoring Mode Installation
No installation is required for the engine coolant temperature monitoring
function.
14.2.2 Engine Oil Pressure
14.2.2.1 Engine Oil Pressure Monitoring Mode Operation
Engine oil pressure is automatically monitored by the engine ECM to protect
the engine from operating without sufficient oil pressure, as low oil pressure
could lead to catastrophic engine failure. The minimum oil pressure is defined
as a function of engine speed, which is factory set and non-configurable.
Once these values are tripped the engine will raise an appropriate event code
and take appropriate action. The table below shows the oil pressure trigger
levels for each monitoring mode configuration.

14.2.2.2 Engine Oil Pressure Monitoring Mode Configuration
The low engine oil pressure monitoring mode is a factory set monitoring
mode, which has fixed thresholds that, cannot be adjusted.
