Seven-Day 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 seven-day time switches HW01 to HW32 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 is backed up in the event of a power failure and continues to run,

although the time switch relays will no longer switch. The contacts are kept

open when de-energized. Refer to General on page A-1 for information on the

buffer time.

Wiring of a 7-Day Time Switch

A 7-day time switch is integrated into the circuit diagram as a contact.

IMPORTANT

The GET function blocks are assigned the value 0 when the

power supply is switched on.

IMPORTANT

The procedure for setting the time is described under Setting

Date, Time and Daylight Savings Time on page 7-11.
