Cable used to wire between the sensor and the time
switch/controller, must be double insulated. The time
switch/controller must be isolated from the supply when making
connections to the sensor terminals. All screw terminals must be
protected against accidental contact or damage. Conductors
wired to them must be properly prepared in order to maintain the
finger and back of hand protection (VDE 0106).
The load applied to the output relay contacts must not exceed the
ratings shown in the technical specification.
Settings
To access all the control buttons, lift the front cover. The six buttons, 3-
position switch and daylight level control potentiometer are shown in
figure 3.
Initial switch on
The time switch must be installed and wired in accordance with the
instructions detailed above. On applying power to the unit, the LCD
display wil take about thirty seconds to become visible.
Erase all settings
This procedure is best followed when the time switch/daylight sensor is
first installed.
1. Press the S and OK buttons simultaneously.
2. Release the buttons. The memories have now been erased and the
time switch is ready to accept new settings.
Setting the actual time
1. Press the
button once. The clock indicator will be displayed
above the numeric time display.
2. Press the S* button until the correct hour (0-23) is showing.
3. Press the OK button once. The minute display will flash.
4. Press the S* button until the correct minutes (00-59) are showing.
5. Press the OK button once. The day indicator will flash above day 1.
6. Press the S* button until the day indicator appears steady above the
actual day (1-7).
7. Press the
button when the set time coincides with the actual time.
This starts the clock.
*Note: Pressing and holding in the button will cause the setting to
be advanced rapidly. This can be done until the required
setting is near. Thereafter, short duration pulses will advance
the setting more slowly until the required setting is reached.
Setting switching programmes
To assist in programming, the programme has two block settings, days
1 to 7 and days 1 to 5. Using block programmes saves time in entering
them. It does not save programme memory. The switching commands
may also be assigned to the individual applicable days.
Choosing block or individual day programming
Repeated pressing of the
button displays the following items:
1. Clock set.
2. Completed programmes (not applicable if clearing memory
procedure has been followed).
3. Programme by 7-day block picture, identified by day indicators
above and below all days 1 to 7.
4. Programme by 5-day block picture, identified by day indicators
above and below all days 1 to 5.
5. Programme by individual day picture, identified by no day indicators
showing.
6. Normal running.
Continuing to press the
button displays the items again.
Individual day programming
To commence individual day programming, scroll through the items,
listed above, until the programme by individual day picture is displayed:
1. Press the S button once. The on time hour display will flash.
Continue to press the S button to set the required on time hour (0-
23).
2. Press the OK button once. The on time minute display will flash.
Press the S button to set the required on time minutes (00-59).
3. Press the OK button once. The on day indicator will flash above day
1. Now is decision time:
4. Is the on time applicable to this day?
Yes: If yes, press the OK button once and the S button once (except
when day 7 is reached). Another on day indicator will flash
above the next day. Proceed again from point 4.
No: If no, press the S button once (except when day 7 is reached).
An on day indicator will flash above the next day.
Proceed again from point 4 until day 7.
If the above procedure is continued beyond day 7, all entries will
cancel and will require re-entering.
5. Press the
button. The off time hour display will flash.
6. Use the S button to set the required off time hour (0-23).
7. Press the OK button. The off time minutes display will flash.
8. Use the S button to set the required off time minutes (00-59).
9. Press the OK button. The off day indicator will flash below day 1.
Now is decision time again:
10.Is the off time applicable to this day?
Yes: If yes, press the OK button once and the S button once (except
when day 7 is reached). Another off day indicator will flash below
the next day. Proceed again from point 10).
No: If no, press the S button once (except when day 7 is reached).
An off day indicator will flash below the next day.
Proceed again from point 10 until day 7.
If the above procedure is continued beyond day 7, all entries will
cancel and will require re-entering.
11. Press the
button. The programmed picture will be entered into
the memory and the display will return to the normal running mode.
12. If further programmes are required, proceed from the beginning of
individual day programming. Unused programming pictures will be
presented in the three programming choices:
7-day block, 5-day block, individual day.
When all eight programming pictures have been used, the display will
read full after scrolling through all the entered programmes.
Block programming
The procedure for programming by 7-day and 5-day blocks is similar to
individual day programming. The only difference is that on/off day entry
is automatically entered.
Programme review/cancel
1. Press the
button to review programme pictures.
2. When a picture required to be changed or deleted is displayed,
press the C button. The programme picture will clear, permitting re-
programming.
3. After cancelling all the unwanted switching point commands, press
the
button to return to the normal running mode.
Override facilites
Manual on/off override
This facility permits the changing of the output relay state, contrary to
the programmed position, until the next opposite command.
Example:
The time switch is programmed as follows:
on at 08:00...............off at 12:00
on at 13:00...............off at 17:00
At 10:00 the manual off override is used. The time switch will remain
off until 13:00, the next opposite (on) command.
The programme will continue as normal thereafter. To effect manual
override, press the + button. Repeated pressing of this button will
cause the output relay to alternate between on and off.
