1. Set the Timer
Do not
rotate the dial anti-clockwise as this will
damage the mechanism.
Rotate the minute hand clockwise until the arrow-
head on the clock face aligns with the correct time
on the outer dial—see Fig. 1.
The dial shows the 24 hour clock. Note that 9 =
9:00 a.m., 21 = 9:00 p.m. When setting-up the 7
day version, align correct time on outer dial, within
current day sector of dial. Please note: on the
SBSW seven-day timer, the weekdays are printed
around the edge of the dial in abbreviations of three
languages.
To set ON / OFF times, move all tappets between
ON and OFF times required to the outer edge of the
dial. See Fig. 1.— to set ON at 7:30 a.m. and OFF
at 10:30 a.m. move all tappets to outer position
between 07:30 and 10:30 on the dial. Set any other
ON/OFF times in a similar manner.
2. Manual Override
There is a three-position manual selector built-in to
the clock dial face. See Fig. 2.
Position 1 ’I’ = ON
Position 2
= AUTO
Position 3 ’0’ = OFF
The timer incorporates a changeover switch. See
Fig. 3. Therefore, when in use as a general purpose
timer, the manual switch functions as follows:
In position 1, terminal 2 output is ON
In position 2, the output will switch between termi-
nals 1 & 2, as determined by tappet positions.
In position 3, terminal 1 output is ON.
