Description:
National Time/Rauland - 110VAC or 230VAC or 24VAC 60 Hz is used to run the clock normally.
Applying a 25 second reset signal when minutes equal 00 and seconds equal 00 will cause an hourly
correction. Applying a 24 minute reset signal when hours equal 06 or 18 and minutes equal 00 and
second equals 25 will cause a daily correction.
Rauland Digital - Applying a half second pulse for every minute to the Dig. Line will bring the clock to
the correct time. The clock will jump to the correct time at the end of the correction pulse.
Note: For better synchronization, it is recommended to work on a 60 Hz time base.
Note: Use only an isolated transformer to run the clock in 24 volt mode.
