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
EZD is equipped with a real-time clock which you can use in
the circuit diagram as a 7-day time switch and a year time
switch.
EZD provides 32 year time switches HY01 to HY32 for a total
of 128 switching 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
failure and continue to run. However, the time switch relays
will no longer continue to switch. The contacts are kept open
when de-energized. Refer to Chapter “Technical data”,
Page 407 for information on the buffer time.
