Eaton HFX Series - Fault Conditions; System and User Faults

EATON HFX Product Family Installation and Operation Manual E-ELCL-II002-E2 July 2019 49
24.0 FAULT CONDITIONS
Note: That while every effort has been taken to assist in
identifying faults and providing a system to manage these
faults, there is still the possibility of faults occurring that are not
detected. The system designer must take this into account.
This system is intended to assist with faults but is not intended
to take the place of a safety system.
The controller features a highly rened fault
management system. The system consists of a fault
table of predened system faults. All of the faults
are mapped to addresses that are directly accessible
in the application control program. There is also
a reserved area for user dened IEC faults in this
section. This is very exible as all faults can be easily
scanned through in one area of the environment.
Both the predened System Faults and the User
Faults feature active and historic fault indication.
Please see below:
Fault table indicating User and System faults
The range limits for many of the faults have default values that can be overwritten in the appropriate
I/O conguration tab. Please see below:
Note in this example the range limit for an analog input is highlighted (34,000 mV), this is used for dening the appropriate range limit and if
exceeded the corresponding fault will trigger if active.
