Fault History
The 1311 programmer can be used to access the controller’s fault history le. The programmer will read out
all the faults the controller has experienced since the last time the fault history le was cleared. Faults such
as contactor faults may be the result of loose wires; contactor wiring should be carefully checked. Faults such
as over temperature may be caused by operator habits or by overloading.
