Rolling Reset on the PL1000E{7610} Caterpillar

Electric Power Generation: All

Engine:Industrial, Marine, and Generator Set that Use Flash Programming All

Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

The PL1000E ECM contains a "Rolling Reset" function. The Rolling Reset function resets the ECM to default values.

This function protects the ECM from repetitive power cycles or from a corrupted Parameter Configuraion List (PCL) file. The PCL file contains the configuration for the ECM. The PCL file is stored in the memory on the ECM.

A Rolling Reset can occur under the following circumstances:

• Five power cycles occur within sixty seconds which removes the PCL file from memory.

• Six power cycles occur within sixty seconds which resets the configuration of the ECM to the default values.

• A corrupted PCL file is loaded onto the ECM.

Solution

Technicians should observe the following:

• During maintenance, ensure that power is removed to the PL1000E ECM in order to prevent cycling the power to the ECM.

• Use the latest version of the Cat Electronics Technician service tool and Communications Toolkit when a PCL file is created.
