Use the DIP switch to set any of the following four ranges, according to the chart shown on
the next page.
0.1 to 1 second (typical)
1 to 10 seconds (typical)
10 to 60 seconds (typical)
1 to 10 minutes (typical)
The timing operation can be paused if so specified by the program. Therefore, the timers can
also be used as cumulative registers.

SET and TIME UP
External variable resistors can be used to set the time value when the IN/EXT selector is set
to OFF (EXT). Use 20 k variable resistors.
