6.2 Command Programming
Each RO switch can be switched using two different ripple control commands (command 1
and 2)
Command 1
Command 2
Command 1 acts on the time function which can be assigned to the switch.
If no time function has been programmed the switch switches directly.
Command 2 is a direct switching command. This command directly switches
the switch. If a time function is running on the switch, the time function is
interrupted (exception: with a loop cycler only the switch is switched while
the loop continues to run).
6.3 Time Delay
The time delay function causes the delayed switching of the switch. The times can be fixed
or fixed plus random times.
6.4 Wiper
The wiper is a pulse which has a wiping time. The waiting time can be fixed or fixed plus
random time.
Command 1 ON starts the wiper without switching the switch; the switch is switched
to ON when the waiting time has elapsed, and to OFF at the end of the wiping time.
Command 1 OFF stops the wiper and switches the switch to OFF.
Command 2 stops the wiper and directly acts on the switch.

6.5 Standard Cycler
The standard cycler causes continuous repetition of the ON time and the OFF after the
waiting has elapsed. The switch is switched to ON during the transition from the waiting
time to the ON time, and to OFF during the transition from the ON time to the OFF time.
The waiting time can be fixed or fixed plus random time.
Command 1 ON starts the cycler (again) with the waiting time and switches the switch
to OFF.
Command 1OFF stops the cycler and switches to switch to OFF.
Command 2 stops the cycler and directly acts on the switch.
6.6 Air-conditioning Cycler
The air-conditioning cycler causes continuous repetition of the ON time and OFF time after
the waiting time has elapsed. The switch is switched to ON during the transition from the
waiting time to ON time, and to OFF during the transition from ON time to OFF time. The
waiting time can be fixed or fixed plus random time.
Command 1 ON starts the cycler (again) with the waiting time and switches the switch
to OFF.
Command 1 OFF stops the cycler and switches the switch to OFF.
If command 1 OFF is actuated while the ON time is running, the cycler is not stopped
until the ON time has elapsed, then the switch is switched to OFF.
Command 2 stops the cycler and direct acts on the switch.
6.7 Loop
Loop is a continuous cycler with the ON time and the OFF time. If a power down occurs, the
remaining time of the currently active cycle phase is saved and reloaded when the power is
restored. Loop will continue to run where it had been interrupted.
After programming, the system is automatically started with the ON time and a
switching of the switch from OFF to ON.
Command 2 directly acts on the switch without influencing or stopping the Loop.
Command 1 ON is ignored if it is actuated while the ON time is running.
If command 1 ON is actuated while the OFF time is running, the ON time starts and
switches the switch to ON.
Command 1 OFF is ignored if it is actuated while the OFF time is running.
If command 1 OFF is actuated while the ON time is running, the OFF time starts and
switches the switch to OFF.
6.8 Timer
Timer is a cycler which features a measuring time and a reset time.
Command 1 ON starts the timer with the reset time switches the switch to OFF.
Command 1 OFF is ignored.
Command 2 stops the timer and directly acts on the switch.
When the timer is stopped command 2 directly acts on the switch without starting the
timer.

6.9 Failsafe
The failsafe function serves to bridge the absence of ripple control signals. The general
failsafe may:
Set time program to active.
Set time program to passive.
Invoke emergency time program strategy.
Direct Switching: after the failsafe time has elapsed, the switch switches ON or OFF.
Time Function: after the failsafe time has elapsed the time function of command 1 is
carried out by switching the switch either to ON or to OFF. If no time function has
been programmed the switch switches directly to ON or to OFF.
6.10 Learning Function
The learning function remembers the operation of the switch and causes that pattern to be
repeated if the failsafe state is entered. If the RO3 does not receive a ripple control signal
within the programmed failsafe time it will automatically repeat the switching process
memorised on the previous day.
6.11 Power On
Power On is triggered by the following events:
After a cold start (when connecting the system to the mains power supply)
After programming (Software Reset)
After the mains power supply has been interrupted for more than the mains bridging
time
6.12 Memory
After a Power On and after the memory time has elapsed, the memory function once more
executes the command that was received on this switch before the Power Down occurred.
The memory function is interrupted if a command is received on this switch during the
memory time. The memory time can be fixed or fixed plus random time. The following
functions do not influence the memory function:
Setting the switches
Failsafe functions (including learning function)
Time programs
6.13 Power Down
If Power Down continues for more than 600ms, the most important data (time, learning
function times, memory function times, Loop times) is stored in the EEPROM. If a backup
clock is installed, the receiver time is loaded into the backup clock). The following functions
can be carried out during a Power Down:
Switching the switch to ON
Switching the switch to OFF

6.14 Switch Inverter
If the switch inverter has been programmed, the switch switches in an inverse manner with
respect to the programmed switching direction during a switching action.
In the case of a switching action to ON, the switch switches OFF
In the case of a switching action to OFF, the switch switches to ON
This applies to all functions: Direct switching actions, Time functions, Failsafe functions
(incl. learning functions), Power On, Power Down, Time programs and Setting the switches.
6.15 Switch Repetition
If the switch repetition has been programmed, the current switch position is retained in an
electronic memory and the coil of the switch is pulsed to confirm this position at intervals of
60 seconds. This is designed to prevent unauthorised manual operation of the switch. If
low frequency load shedding is used, switch repetition is automatically activated.
6.16 Low Frequency Load Shed
Low Frequency Load Shedding is used to substitute for spinning reserve to cover for the
outage of a single large generator or inter-connector in an electricity system.
6.17 On Programming
This defines the state that the receiver is switched to during programming. If a power down
off function is programmed the switch will go off when the receiver is removed from the
programming station but when it is installed, after the memory delay, it will go to the
memory state set by this dialog.
7 OPTIONAL BACKUP CLOCK
As a standard, the RO Ripple Control receiver operates on the basis of an internal clock
which is used for the time programs, the learning function and the telegram memory. The
clock goes by the mains frequency and can be synchronised by means of Ripple Control
signals.
If a power down occurs, the current time is stored. When the power is restored, the saved
time is loaded and the RO continues to operate with this time. Therefore, the interval of the
power down will be lost. The time is not adjusted until the next synchronisation process
takes place via Ripple Control.
The backup clock is available as an option for backup during power down times. The main
components of the backup clock are a real-time clock and a buffer capacitor for power
failures. The optional backup clock is mounted on a separate circuit board which is soldered
onto the standard circuit board in the manufacturing process.

7.1 Function with integrated Backup Clock
If a backup clock is installed, the RO still works with an internal time which goes by the
mains frequency. If a power down occurs, the current time is loaded into the backup clock.
During the power down the backup clock is powered by the buffer capacitor and continues
to work. When the power is restored, the RO time is adjusted by the backup clock. In this
way, the RO will still have the correct time even after a power down has occurred.
If the RO contains a backup clock, the internal RO time is also adjusted by means of the
Ripple Control signal. Since, in the case of a power down, the current time is written into
the backup clock, the backup clock can also be synchronised with Ripple Control.
7.2 Technical Data of the Backup Clock
Power reserve with buffer capacitor: > 36h
Charging time for buffer capacitor: 3h (for 36h power reserve)
Accuracy: < 3s after 36h power reserve at 25ºC
Temperature stability: < 0.15s / ºC / 24h during power reserve
