Wiring with Pico GFX-70 4-111
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
Pico GFX-70 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.
Pico GFX-70 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. See General on page A-1 for
information on the buffer time.
IMPORTANT
The procedure for setting the time is described under Setting
Date, Time and Daylight Savings Time on page 7-11.
