1. GENERAL INFORMATION 

 
The purpose of this troubleshooting handbook is to provide additional information to assist 
a service or maintenance person in identifying malfunctions or system problems with the 
PAT System. A digital voltmeter and regular maintenance and service tools will be 
required to troubleshoot the system. Note: Knowledge of how to use a digital voltmeter is 
assumed. 
 
REFERENCE: 
Operator’s and Calibration Handbook PAT 031-300-190-015 
 
SYSTEM MALFUNCTION: 

 

In case of a malfunction of the system, an error code which 
identifies the system malfunction will be displayed in the 
reeving portion of the display. The error codes are listed in 

Section 4, Error Codes. The table identify various faults that can occur with the EI65, 
explain each fault, and describe the action which shall be taken to correct the fault. 
 
Faults within the electronic microprocessor shall be repaired by factory trained service 
personnel. When these faults occur, contact your authorized dealer or service 
organization. 
 
SYSTEM PROBLEMS: 

 

If the operator identifies a possible problem in the system, perform the pre-operation 
inspection in the Operator’s Handbook 031-300-190-015 to define the problem. Use the 
following drawings to identify the problem. 
 
SYSTEM DESCRIPTION: 

 

The PAT Length-Angle-Radius-Load Indicator System EI65 has been designed to provide 
the crane operator with the essential information required to enable the machine to be 
used within its design parameters. The EI65 System indicates the length and angle of the 
boom, tip height, working radius and the total weight being lifted by the crane. Using the 
various sensors and the limits set by the operator, the EI65 System warns the crane 
operator of certain approaching hazardous conditions which could occur during the 
operation of his crane.  
 

 

WARNING 

 

Always refer to operational instructions and load charts provided by the crane 

manufacturer for specific crane operation and load limits.
