Master Clock Function
The PERFECT 2030 time recorder can be used as a master clock to control and
synchronize other PERFECT time recorders and ISGUS slave wall clocks.
For this feature to be functional, the master clock hardware module (payable option)
must be installed on the time recorder’s CPU board and all slave clocks must be
wired and connected to it.
After the master clock function is activated, the slave clocks must be synchronized.
Therefore, the date and time setting routine must be called up after programming.
The time recorder will automatically synchronize the slave clocks after date and time
has been set.
There are two types of master clock systems, reverse polarity and straight polarity.
The advantage of reverse polarity systems is that they allow the transmission of
1 second impulses to the slave clocks for test and synchronization purposes.
