12 Faults
12.1 Purpose and enabling
Function block "Faults" collects all fault messages and sends them to the fault
display, fault relays, and via bus.
Purpose
Faults
Enable the fault block by configuring fault inputs 1...20
or
assigning a fault relay.
Enabling
Many faults are acquired automatically and need not be specifically configured in
function block "Faults". These faults are described with the relevant function. The
fault block does not have to be enabled to display these faults.
Note
12.2 Fault priorities and acknowledgement
There are 2 types of fault priorities:
Fault priorities
Urgent
Fault messages representing plant risks
or
for which trouble-
free plant operation is no longer guaranteed.
Not urgent
Fault messages representing risks that do not represent a
great risk to plant operation.
There are 2 types of fault acknowledgement:
Fault acknowledgement
(No acknowledgement).
Acknowledge
Acknowledge and reset
See Section 14 on fault acknowledgement.
Note
Impact of fault
Faults "No stop" and "Stop" are not available in RMS705B. Plant stops
or
partial
plant stops are configured internally, e.g. using stop conditions
or
logical links to
start/stop conditions of the function blocks.
