When the ECM activates an event code, the operator will be alerted by the Caterpillar Monitoring System. The active event will be logged by the ECM and can be viewed with the Caterpillar Monitoring System or the Caterpillar Electronic Technician (ET) service tool.
Warning Levels
The ECM will assign one of three warnings levels to and active event code according to the severity of the abnormal system condition. Each warning level require a specific response from the operator. The warning levels and required operator response are listed below.
Warning Level 1
Warning level 1 alerts the operator that a machine system requires attention. The operator should check the involved system condition or perform maintenance on the involved system at the earliest possible time.
Warning Level 2
Warning level 2 requires changing the operation of the machine or performing a maintenance procedure. Failure to correct the problem that caused this warning may result in damage to the involved machine system components.
Warning Level 3
Warning level 3 requires an immediate safe shutdown of the machine in order to avoid damage to the machine or injury to personnel around the machine. The problem that caused the event will have to be corrected before machine operation can resume.
Indications and System Response
Caterpillar Monitoring System
The monitoring system will alert the operator when an event code is active. Event codes are activated in one of three warning levels according to the severity of the condition. The monitoring system response to these warning levels is shown in the following table.
| WARNING OPERATION | |||||
|---|---|---|---|---|---|
| Warning Category | Warning Indications (1) | Required Operator Action | Possible Result (4) | ||
| Alert Indicator Flashes (2) | Action Lamp Flashes | Action Alarm Sounds | |||
| 1 | X | No immediate action required. The system needs attention soon. | No harmful or damaging effects. | ||
| 2 | X | X | Change machine operation or perform maintenance to the system. | Severe damage to components. | |
| 2-S | X | X | X (5) | Immediately change the machine operation. | Severe damage to machine components. |
| 3 | X | X | X (3) | Immediately perform a safe engine shutdown. | Operator injury or severe damage to components. |
| ( 1 ) | The warning indications which are active, are marked with an "X". |
| ( 4 ) | This is the possible result if no operator action is taken. |
| ( 2 ) | At a 10 Hz rate. |
| ( 5 ) | The alarm is on continuously. |
| ( 3 ) | Pulsating alarm. |
Electronic Technician Service Tool
When an abnormal telehandler operating condition occurs, the status screen on the Caterpillar Electronic Technician (ET) indicates that there is an active event.
Event codes are displayed on Cat ET in the following format:
EXXXX Description of the code
The "E" means that the code is an event code. The "XXXX" is a numeric identifier. The numeric identifier is followed by a description of the code.
Active event codes are listed in ascending numerical order. The code with the lowest number is listed first. The active event code is removed from the list when the condition is no longer present.
Logged Event Codes
Every event code is logged in the ECM memory. Logged event codes are listed in chronological order. The most recent code is listed first.
A logged code is cleared from memory when one of the following conditions occur:
- The service technician manually clears the code.
- The code does not recur for 1000 hours.
- A new code is logged and there are already ten logged codes in memory. In this case, the oldest logged code is cleared.
Note: Always clear logged event codes after investigating and correcting the problem which generated the code.
Troubleshooting
Perform the following steps in order to troubleshoot an event:
- Obtain the following information from the operator:
- The event and the time of the event
- Determine the engine's operating conditions at the time of the event. Conditions such as engine rpm and load may be important.
- Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
- The event and the time of the event
- Verify that the event is not due to normal machine operation. Verify that the event is not due to error of the operator.
- Check all fluid levels and all oil levels.
- Troubleshoot and repair any active diagnostic codes.
Telehandler Event Code List
The following table lists the event codes that apply to the telehandler control system. The recommended operator response is listed. Use the Cat ET service tool in order to determine the event codes that are active or logged.
