Curtis 1311 Manual
3.6 Reading Faults and the
Diagnostic History file
Model 1311 allows access to the present and past status of the
system or unit you are connected to. Each Curtis product
runs continuous self-diagnostics and will record and log an
error event in non-volatile memory. When the 1311 is con-
nected to the unit, this log file is automatically uploaded into
the handheld programmer.
To see the present status of the unit, use the Menu Navigation
Key to select
'Faults -> System Faults'
To access this log, use the Menu navigation Key to select
'Faults -> Fault History'
The faults are shown as a code and descriptive text. If there
are multiple faults, you may have to scroll through the list
using the Up and Down Buttons on the Menu Navigation
Key.
It is useful to clear the fault history after reading it. To do
this, select
'Faults -> Clear Fault History'
You will be asked to confirm your actions. Use the
Increment arrow (+) for yes and decrement arrow (-) to can-
cel and not clear the Fault History.
The MC-2 systems have an additional Sub-Menu to select the
module. For example 'Faults -> Controller -> Fault History'.
