1 Slave Clock Control Board 7406RC

RC Function Board 7406RC is a Slave Clock Control Board for controlling two lines (clock
chains) with clocks operating on a pole-changing pulse basis or DCF77 time code
clocks.

It is designed for the central

hopf

clock System 7001RC in eurocard size with a 4HP/3U

front panel.

 After the once-only set-up of the clock equipment the system operates

maintenance-free.

 The pulse output of the two lines is monitored so that, in the event of a fault or pulse

failure, an error message can be transmitted.

 In the event of a fault in pole-changing mode, the current time of the slave clocks

is stored, such that after the fault has been removed or when the equipment is re-

started, the last-transmitted time is available and the slave clocks are re-set
independently.

 The pulse lengths are adjustable in pole-changing operational mode.
 A constant voltage supply source external to the system 7001RC can be

connected to RC Function Board 7406RC, to control and supply power to the slave
clocks (see Chapter 9 Technical Data).

 RC Function Board 7406RC can synchronise self-setting DCF77 time code clocks

with the DCF77 data telegram via the line cables. If these clocks have a power
supply independently from the System 7001RC they continue to run whilst there is a
fault (DCF77 data telegram failure).

 The summertime/wintertime changeover points are executed in conjunction with

RC Function Board 7406RC.

 The time basis of the lines can be transmitted in local time or UTC time.
 Due to its hot-plug capability, the Board can be removed from and re-connected to

the running 7001RC system at any time and at any point, without affecting the
function of other system boards. However, to provide the power supply to slave
lines, it can be fixed to a connection slot in system 7001RC by means of additional
internal wiring.

 Slave Clock Control Board 7406RC is configured via the

hopf

System 7001RC

display / keyboard or via

hopf

_RC remote software.

 Monitoring for insufficient line voltage

2 Clocks in Pole-Changing Pulse Operation

In pole-changing operation, lines transmit every second for second lines and every minute
for minute lines, alternately a positive or negative voltage pulse with the set pulse length.

3 DCF77 Time Code Clocks

In DCF77 time code operation, lines transmit a DCF77 time code signal, changing pole on
every second change. The DCF77 time code signal is coded according to the period of the
zero volt position, 100msec (= logic 0) and 200msec (= logic 1).
