Synchronize the Slave Clocks
Only after finishing the complete programming of the time recorder, should you then
proceed to synchronize the slave clocks.
First, make sure that all reverse polarity type slave clocks are set to the same
polarity. This can be verified by transmitting single impulses from the time recorder.
Refer to the previous instructions given in section "Time / Date". If any reverse
polarity slave clock does not advance when a pulse is transmitted form the time
recorder, reverse the connecting plug of the affected slave clock.
Then all the slave clocks have to be set manually to the same time and the
transmission of the single impulses has to be repeated.
When all the slave clocks switch synchronously, the time of the slave clocks has to
be entered at the master clock. After the entry, the slave clocks are synchronized
automatically to the current time of the master clock.
While synchronizing the time, it is possible to punch at the time recorder.
During e.g. fall daylight savings time changes the time recorder suspends the
transmission of minute impulses for one hour, eliminating the need to reset slave
clocks.
In the case of an electrical short circuit or overloading of the slave clock output
module, a current limitation feature protects the master clock from damage.
