Starting and stopping a pulse sequence via channel A
Normal switching points and pulse switching points can be entered
for channel A.
The pulse switching points are entered in the same way as the

the pulse switching point.
It is not possible to enter pulse durations for channel A.
A switch-on point activates channel A, while a switch-off point
deactivates channel A.
In contrast, a pulse switch-on point starts the pulse sequence on
channel B, while a pulse switch-off point stops the puise sequence
on channel B.
An impulse sequence started via a pulse switch-on point can be
stopped by manually pressing [email protected] button. Conversely, a pulse
sequence started manually can be stopped by a pulse switch-off
point. The pulse sequence always starts from the beginning.

6. Astronomical switching functions —-
For the astronomical switching functions, the clock calculates the
morning and evening twilight times. The twilight times can, like the
entered switching points, be used to execute switching functions.
At dusk, for example, a light can be switched on and switched off
again at dawn. The shifting of the twilight times over the year is
taken into account in this function.
Further ways of linking the twilight times with entered switching
points can be specified by selecting the “Astronomical functions”
(A 1 to A 5).
0.1 Selecting the astronomical runction
The time switch provides 5 astronomical functions.
For setting: see Table 1, point 4.5
Longitude and latitude: the twilight times depend on the geo-
graphical position of the place of operation. The default setting is
50° north (latitude) and 10° east (longitude), corresponding roughly
to the geographical position of Frankfurt/Main, Germany.
Clock zone: The standard clock zone is set tor Central Europe.
The value must be changed corresponding to the place of opera-
o Other cities are listed in the enclosed leaflet together with
their longitudes/latitudes and clock zones. For the setting
of other values, see Table 1.
Sun below horizon: the time switch calculates the current twilight
times based on the angles entered. The default setting is an angle
of 6°, corresponding to the “civil twilight“ (12° = nautical twilight,
18° = astronomical twilight).
For setting other values, see Table 1.
Morning and evening time differential: the time differentials
enable the twilight switching points to be shifted and determine the
morning and evening switch-on duration (see Table 1). The setting
0:00 makes the time differentials ineffective. Only effective for the
functions A1 and A2.
Twilight switching points: when an astronomical function has
been selected, the clock calculates the current twilight times.
These are recalculated at 0:00 h on each subsequent day.
The twilight times are stored as special switching points and can
be displayed by pressing the SET] button:
The time is displayed, the colon flashes.
The dawn switching point is displayed.
Pressing [SET] again displays the dusk switching point.
The date must be entered when using the automatic
summer/winter time switchover and astronomical func-
il tions. if the astronomicai function is deactivated (= AO),
TT - On Two-channel timers the astronomical switching
functions can only be executed with channel A.
no twilight switching points are displayed.
6.2 Astronomical function A1
In astronomical function A1, the dusk switching point acts as a
switch-on point and the dawn switching point as a switch-off point.
Function A1 also provides the possibility to shift the calculated
twilight switching points. One time differential each can be set for
both the dawn and the dusk switching points, enabling execution o
the twilight switching points to be advanced or retarded. In the
case of a negative differential value, the switching point is acti-
vated correspondingly earlier, with a positive value correspondingly
later. To change the programmed default settings,
see Table 1.
5 Activating astronomical function At makes additionally
set switching points ineffective. This applies to the One-
i channel timer as well as channe!A of the Two-channel
6.3 Astronomical function A2
Function A2 enables tha switching on of a consumer item after
dusk or bafore dawn for a desired period of time.
The period during which the consumer item (e.g. a light) is
switched on aller dusk is determined by the evening time differan-
tial. The morning time differential determines the duration of
switch-on time before dawn (see Tabla 1).
It one of the switching sequences Is not to be executed in the
evening or morning, the corresponding time differential must be sel
© Activating astronomical function A2 makes additionally
sel switching points ineffective. This applies to the One-

Function A3 links the switching points entered for channel A with
the twilight times. Only switching function set to operate which in
twilight time and are linked with two additional ON-OFF-swilching
ON-switching point switches ON
OFF-switching point switches OFF
‘Table 3
In example 1, the time switch switches the consumer item ON at
20:00 and OFF again at 22:00. If dusk begins after 22:00, the swit-
ching point is ignored, and the consumer item is not switched on.
Table 4
In example 2, the time switch switches the consumer item ON at
20:00 and off at 22:00 the next morning ON at 5:00 and OFF at
7:00. If dusk begins after 22:00, and dawn before 5:00, the pro-
grammed switching points are ignored.
6.5 Astronomical function A4 (OR-linked)
Function A4 facilitates another way of linking the twilight times with
the switching points entered for channel A. Switch-on phases
stipulated via switch-on and switch-off points and the switch-on
phase between dusk and dawn have equal status. The conse-
quence of this for channel A is that the switch-on phases overlap.

6.6 Astronomical function AS
Function AS enables channel A to be switched on and off via two
separate paths. The channel is always switched on via the dusk
switching point and swilched off with the next switching point on
the following day, not by the dawn.

7 Setting cycle error correction
o Cycle error correction can only be set when mains voltage
i is connected.
Cycle correction value: the cycle precision of the time switches at
room temperature (20° C) is generally better than | second per
day. Higher ambient temperatures, however, can cause an addi-
tional cycle error. If the ambient conditions are constant to the
greatest possible extent, the error can be minimised by resetting
the cycle correction value. To do this, the cycle error is determined
by comparing it with a time signal (e.g. radio or television) over a
period of exactly one week. The value in seconds of cycle devia-
tion per week obtained in this manner is then taken into account
when resetting the cycle correction value.
If the time switch is fast, the cycle correction value is reduced by
the number of seconds. If the time switch is slow, the value is
increased by the number of seconds.
The factory default setting for cycle error correction is for condi-
tions of approx. 20 °C. The newly ascertained cycle deviation must
be added to or subtracted from the default value.
Default value for cycle correction: +2 sec par week
Newly ascertained cycle deviation: +3 sec per week.
3 seconds must be deducted from the default setting, i.e. ~1 must
appear in the display (for setting, see Table 1).
8 Technical details
8.1 Updating the switching outputs
If new switching points are entered or the current time is changed,
the current switching status is re-calculated in each case, and the
entered switching points are updated accordingly within 1 minute.
8.2 Behaviour in the case of electrical supply failure
In the event of loosing the supply voltage, the switching relay(s)
is/are deactivated (OFF position), and the digital display is
switched off.
Approximately 1 minute after supply voltage is restored, the relays
commence working again as programmed.
Should the cycle reserve be exhausted after a longer period of
supply failure, the switching points will be retained indefinitely. Only
the time, day and date have to be re-entered after a certain period
(see 8.3, Cycle reserve).

sumer is obliged to return used batteries. To help preserve the
environment, the time switch should be disposed via an approved
recycling facility.
