IV - Connection to a timing network
4.1 Inverted polarity parallel distribution or AFNOR / IRIG B
1) Connect the impulse line to the "//" and "COM" terminals on the terminal block (A).
2) Select the impulse type (minute, 1/2 minute or AFNOR depending on the model) and set the
clock time (Chapter 8).
Master clock
3) On the initial powering up, the time is initialised at 0h00, 1 jan. 2000.
The clock automatically set up its time base to the correct time when receiving the time
message.
Caution : if the AFNOR signal is lost, the clock continues to operate for 1 hour in independent
mode and then the display goes off. Only the separating colon ":", which stops blinking after 1
minute without signal, remains on, indicating that power continues to be supplied to the clock.
4.2 Inverted polarity series distribution (1/2 minute series)
1) Connect the impulse line to the "COM" and "series" terminals on the terminal block (A).
2) So as to avoid cutting out the network when disconnecting one slave clock, also connect
the 33 Ohm 1/2 Watt resistance (supplied) between the "COM" and "series" terminals on the
terminal block (A).
3) Select the impulse type (1/2 minute) and set the clock time (Chapter 8).
