PROGRAMMING SHEET
TOPICA 450 (STA450S) 7Day Dial
Set time and day
Rotate the outer dial
slowly
in a clockwise direction, until the right corresponding
day segment on the dial is approaching the arrowhead printed on the inside edge
of the dial.
Do not attempt to rotate the dial or the clock hands in an anti-clockwise
direction.
Now rotate the minute hand with your finger, in a clockwise direction, so that you
set the correct time within the day segment. Note that the clock hands are set
within a 12-hour printed ring, and the outer dial is printed with the 24 hour clock.
The illustrations show the clock set at 6:00 a.m. (fig. 1) and 6:00 p.m. Ensure
that you are setting current time accurately with regard to the outer 24 hour dial.
Setting switching times
Tappets should be pushed to the outer edge of the dial for a programmed ON
instruction, and left set to the inner edge of the dial for a programmed OFF
instruction.
All
tappets between the desired ON and OFF times must be pushed
to the outer edge of the dial. Each tappet switches the output for a two-hour
period. Figure 2 shows 8:00a.m. ON – 18:00 (6:00p.m.) OFF Monday – Friday;
8:00a.m. ON – 22:00 (10:00p.m.) OFF Saturday, and no switching programmed
on Sunday.
Manual override
There is a three-position switch built in to the face of the dial.
For automatic timed control, governed by the tappet settings, the switch
should be left in the middle position (as illustrated). The output can be
switched ON at any time, by moving the switch lever to the top position,
marked with a
I
on the dial. Alternatively, the output can be switched OFF
at any time, by moving the switch lever to the lower position, marked with a
0 on the dial. The manual override is a
fixed
selection – the output will
remain ON or OFF (as selected), until the switch lever is moved back to the
middle timed position, marked with a
on the dial
