“Fault History” Tab
The controller memorises the last 64 alarms (both faults
and warnings) which have occurred. These are
displayed in a list, with the most recent appearing at the
top. If the number of stored alarms exceeds 64, the
oldest alarm will disappear off the bottom of the list.
If a new alarm has just occurred, it will appear at the top
of the list. A flashing alarm symbol will be shown next to
the new alarm (
Warning or
Fault). The “Fault
History”
tab will also flash. The tab and symbol will
continue to flash until the alarm has been
acknowledged (reset).
Press the
and
buttons on the right side of the
display to scroll up or down through the list, one screen
at a time (8 alarms).

You cannot reset alarms which are still active (e.g.
emergency stop button not released or motor
temperature still too high).
