24 hour switching
The time switch is to switch for 24 hours. Switch-on time at
0:00 on Monday and switch-off time at 0:00 on Tuesday.
Year time switch
The display system is equipped with a real-time clock which
you can use in the circuit diagram as a 7-day time switch and
as a year time switch.
The display system offers 32 year time switches HY01 to
HY32 for a total of 128 switch times.
Each time switch has four channels which you can use to set
four on and off times. The channels are set via the parameter
display.
The time and date are backed up in the event of a power
supply failure and continue to run. This means that it will
continue to run in the event of a power failure, although the
time switch relays will not switch. When the device is in a
de-energized state, the timer contacts remain open. Refer to
chapter “Technical data”, page 389, for information on the
buffer time.
