8.2 Counters
This screen displays the total number of logged Run, Fault, and Alarm events stored in the DLS4
memory.
8.3 Clear History
The Run,
Fault, and Alarm history logs can be cleared with this option. With “Clear History” selected,
press the ENTER key and a confirmation dialog will appear on the screen. To cancel this action, choose
the “No” option by pressing the F1 key or the ESC key. To confirm this action and clear the history logs,
choose the “Yes” option by pressing the F2 key. A “Please Wait” message will appear on the display for
around 10 seconds while the history is being cleared.
8.4 Fault and Alarm Filters
The Fault and Alarm filters allow the user to indicate specific faults or alarms that should not be recorded
in the Fault and Alarm History logs. Press the Down Arrow key until the “Alarm Filters” or “Fault Filters” is
highlighted on the first line and then press the Enter key. A dot indicates that the corresponding fault or
alarm will NOT get logged. Pressing the Enter key when the desired fault or alarm is highlighted will
toggle the diamond.

8.5 Run Filter
The Run Filter setting specifies the amount of time the motor must be stopped to be considered the end
of a run. This can allow a series of very short runs to be combined into one longer run. Changing this
option to “None” will allow every run to get logged. There are five time options to choose from: None,
100ms, 200ms, 1 second, or 2 seconds.
