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.
