menu
item.
Up to 21 shift periods can be defined. Each row in the above form represents a shift. Enter the day and
time for when the shift starts and when it stops.
The days are expressed as numbers where 1 corresponds to Monday and 7 to Sunday. A shift may have
different start and stop days.
The start and stop times must be entered using 24 h notation, i.e. as 00:00 to 23:59.
Check Automatic clear at shift start to have all shift statistics variables erased when a new shift starts.
Clearing the shift statistics will reset the following:

All counters (No. of cycles, No. of OK cycles, No. of NOK cycles) for each combination of station
and mode used for the Shift Report.

The Station level result variables "Total", "Total OK", and "Total NOK"

The Bolt level result variables "Total", "Total OK", "Total NOK", "Total Type", "Total Type OK", and
"Total Type NOK"
Check Automatic printout at shift end to automatically have the shift report printed when the shift ends.
