( 5) "ALARM SILENCE" switch
(6) Potentiometer"SCROLL" switch (1) - The main display module can operate of five different modes of operation. The "SCROLL" switch is used to display the various parameters that are within each mode. See the "Main Display Module" topic."CLEAR/MODE" switch (2) - This switch is used for selecting among the main display module's five modes of operation. This switch is also used for clearing information from the main display module."LH/RH" switch (3) - This switch can be toggled to display the following parameters for the left side or the right side of the engine: exhaust temperature and inlet air restriction.Action alarm (4) - An alarm condition will not shut down the engine. However, an alarm may precede a shutdown. An alarm indicates a serious condition that requires immediate attention. Annunciation of the alarm informs the operator of an abnormal operating condition or a problem with the monitoring system. The alarm is activated by the main display module when the following conditions occur:
A diagnostic code is active.
An LED indicator on the main display module flashes.
The monitoring system detects an active event. Events can include an alarm, a derating, and shutdown."ALARM SILENCE" switch (5) - This switch enables the operator to silence the alarm for 5 minutes. If the condition that initiated the alarm is not corrected within the 5 minutes, the alarm will sound again.Potentiometer (6) - The potentiometer enables the operator to control the brightness of the lighting for the instrument panel.Main Display Module
The main display module is the brain of the system. This module receives information from the following sources:
Electronic Control Module (ECM)
Sensors
SwitchesThe display on this module includes LED indicators and a liquid crystal display.Indicators
The indicators illuminate in response to information that is received from the ECM via the CAT Data Link.Note: The indicators will illuminate if a setpoint that is programmed into the monitoring system for a parameter is reached. For information on the setpoints, refer to Troubleshooting, RENR5008, "3500B and 3500C Locomotive Engines".
