Diagnostics Chapter 5

➊ Can not be disabled.

A “ProtectFltEnable” parameter (param 42) is used to enable and disable

individual protection faults. This parameter will be a bit enumerated parameter

with each “disable fault” bit enumerated. Not all Faults can be disabled. Setting a

bit to the value “1” enables the corresponding protection fault. Clearing a bit

disables the protection fault. For protection faults that can not be disabled the

value is always “1”.

There are two Protection Fault Reset modes: manual and automatic. When

parameter 41 “ProtFltResetMode” is set to the value 0=Manual mode, a manual

fault reset must occur before the fault is reset. When manual reset mode faults are

latched until a fault reset command has been detected either locally or remotely.

A Manual reset operation is either remotely via the network, locally via the

“Reset” button on the front keypad, or via a DeviceLogix program. A rising edge

(0 to 1 transition) of the “ResetFault” tag will attempt a reset. A rising edge of the

parameter 44 “ProtectFltReset” will attempt a reset. A press of the local blue

“Reset” button on the front keypad will attempt a reset. A rising edge of the

“ResetFault” DeviceLogix tag will attempt a reset. When “ProtFltResetMode” is

set to the value 1=Automatic, “auto-reset” faults are cleared automatically when

the fault condition goes away.
