ƒ  To test the TE Series starter with a motor which will draw less than 

20% of the unit Max Amp rating, you must disable the Phase 
Current Loss (Running) protection as per instructions in section 
5.6.9.a. If this feature is not disabled, the TE Series will give a 
Phase Loss Trip after running for 3 seconds at low currents. 

 

 

Additional information on Fault Codes and possible causes can be 
found in the Service and Troubleshooting Guide. 

Fault Codes and Numbers (in History) 

A three-character fault code is displayed in the LED display at the time 
of the trip event. The first two digits indicate the trip condition (see Table 
7.1). The third digit is a suffix showing the TE Series operating mode 
when the trip occurred. Operating modes are as follows: 
 
Code suffix “A”: Acceleration, meaning that the TE Series was 
ramping up but had not yet achieved “At-Speed” status (see section 
4.2.9.b for a brief description of At-Speed indication). 
 
Code suffix “c”: Constant Speed (running), meaning that the TE 
Series has reached the At-Speed condition and the motor was running 
when the trip occurred. 

 
Code suffix “d”: Decel or Stop, meaning that TE Series was either 
stopped (off, but power applied), or if the Pump-Flex Decel function was 
enabled, it was engaged in the Soft Stop routine set up by F024-27. 

 

 

In addition to these fault display codes, each trip condition has a 
corresponding numeric code that is stored in the Fault History (see 
section 5.6.13.a). These numeric codes follow the display codes 
exactly. The following Table 7.1 shows Fault Display Codes, Fault 
Number Codes, LED indicators that would come on with them and 
descriptions. Additional details are available in the Service and 
Troubleshooting Guide. 
 
Example: If Function F003 (starting overload protection) is set too low 
for the size of the load and causes a trip, the code “oLA” will be 
displayed. Its corresponding number will be entered into the fault 
history. In this case, the number 0010 will be available for display in the 
window of function F085 (Fault History). The time the fault was detected 
is available in Function F086. It is expressed as hh.mm. Therefore, if the 
“oLA” fault occurred at 10:00 am, F086 would display 10.00. The date 
the fault occurred is available in Function F087. The date is expressed 
as mm.dd. If the “oLA” fault occurred on March 1, F077 would display 
03.01. If there were no fault conditions in history, the display in F085 
would read 0000.
