III.5 Installation on a minute or 1/2 minute network
A “Minute” or “½ minute” distribution network only transmits impulses. It is
therefore necessary to set the receiver clocks to the time of this network.
It is not necessary to stop the distribution to add the clock. Simply set it to the
right time and it will increment by one minute on reception of the next impulse
from the master clock.
If in spite of the time setting you still have a time difference of 30 seconds (1/2
minute) or 1 minute (minute), reverse the connection of the line.
Connect the cable as shown in the diagram below.
Then move on to the programming in the technician menu (page 28).
Note: to avoid cutting off the network when a receiver clock is disconnected, also
connect a 33-Ohm resistor (supplied) at the terminal strip input.
Parallel or series minute /
1/2 minute impulse input
