PROGRAMMING SHEET
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. (fig. 2) on
Monday. Ensure that you are setting current
time accurately with regard to the outer 24 hour
dial.
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 3 shows the timeswitch set for
8:00a.m. ON – 18:00 (6:00p.m.) OFF Monday –
Saturday and no switching programmed on
Sunday.
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 "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 "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.
