Table 14.2 Available Engine Monitoring System Parameters
It should be noted that when engine shutdowns are enabled the following
system response is true.
• Severity Level 1 (least severe) = Engine warning
• Severity Level 2 (moderate severity) = Engine Derate
• Severity Level 3 (most severe) = Engine Shutdown
14.1.3 Monitoring System Example
Customer requires the engine to warn the operator and de-rate the engine
(where applicable) upon the engine measuring a monitoring system parameter
above a defined threshold. This threshold in some cases such as the Engine
Coolant Temperature is configurable between a trip threshold min and max
value.
Using the service tool Engine de-rates are activated as shown below
(warnings are always active).
The severity levels for the coolant temperature monitoring can be viewed
using the service tool via the Monitoring Mode screen. In this case level 1, 2
and 3 are available and programmed.
Default values are;
• Level 1 = 108°C
• Level 2 = 110°C
• Level 3 = 114°C
Engine is now operated and the engine coolant temperature rises to a value
above the severity level 1 threshold.
Engine action = Event code E361-1 (or J1939 110-15) is raised and the
engine warning lamp is activated. Engine ECM stores the Event code.
Engine coolant temperature rises to a value above the severity level 2
threshold.
Engine action = Event code E361-2 (or J1939 110-16) is raised and the
engine warning lamp is activated. The engine now begins a derate
according to the coolant temperature derate map.
