Set Slave Line Time/Slave Clocks
When the menu ‘>>setzen’ is selected the slave line is stopped and no pulses are
generated until the menu is leaved.

In the second line the user can edit the slave line time. Here the current time of the
slave clocks should be entered. After confirming with CLR/ACK the time is saved in
the RAM and the UA509P starts generating pulses on the slave lines. The slave line
time is displayed either waiting for the clock time or trying to catch up the clock time.
It is possible to pulse the minute and the second line manually by changing ‘stop’ into
‘run’ behind the according line MIN. or SEK.. In this mode the internal slave line time
is also incremented, so it is necessary to check it again before the menu is confirmed
with the CLR/ACK key. The displayed slave line time must match exactly with the
slave clocks time. Otherwise the slave line time is to set again.
In the set-manually mode it is easy to check the right polarity of the bipolar minute
and second line pulses:
The status LEDs in the front panel of the HUC80E reflect the pulses on the minute
and second lines. If a LED labeled '1' is turned on, the corresponding hand of the slave
clocks must move to an odd count, e.g. if the 1 Min. LED is bright, the minutes must
move to 1, 3, 5, etc. In parallel, if the 0 Min. LED is turned on, all the slave clocks
must show an even minute count. The second line must behave in the same way. If one
of the slave clocks behaves contrary, it must be connected to the master clock with
reverse polarity.
