Pulse function
5.1 Pulse function P1
One pulse duration can be set per channel (A or B).
A pulse is executed via a pulse switching point.
A pulse can also be activated manually (timer function).
The switching point is activated with a pulse of 1 sec (default
setting). Depending on the switching mode ON or OFF, an OFF or
ON pulse switching point is executed.
To set pulse switching points
If pulse switching points are to be executed, the l button has to
be pressed additionally when entering the switching
point (see 3.5).
Two-channel timer: press s, then a to select channel B.
Then proceed as described above.
The current time is displayed again after 60 seconds or
by pressing the i button.
Setting pulse lengths
A pulse length of 00:01 min to 59:59 min duration can be entered
per channel (A or B).
Pressing i and l displays the current value.
h Enter minutes
m Enter seconds
Save by pressing i.
Two-channel timer: Press the i button, then select channel B by
pressing the l and a buttons.
Then continue as described above to enter the pulse length.
Press i to save the settings.
The pulse length set is valid for all pulse switching
points (P1).
Timer function
The timer function is used to switch from the OFF to the ON
position or vice versa.
The timer function cannot be used in the ON FIX and
OFF FIX modes (permanent switching).
The timer function is initiated by pressing the l button.
Two-channel timer:
Press a to select the channel, then press the l button.
Cancel timer function
One-channel timer: press the o button.
Two-channel timer: Press a to select the channel, then press
the o button.
If an ON pulse is cancelled, the time switch sets itself to
the OFF Automatic / position (according to the program)
or vice versa.
5.2 Pulse function P2 (description)
Using pulse function P2, each pulse switching point can be assigned its own pulse duration. On entry, a pulse switching point is
always followed by the associated pulse duration.
A pulse duration of between 00:00 min and 59:59 min can be
entered.
There is no timer function available in the P2 pulse
function mode.
Setting pulse function P2: see Table 1.
Setting pulse switching points with pulse duration
In addition to entering a switching point (see 3.5), the l button is
activated, thus marking the pulse switching point. The pulse
symbol n appears in the display. On pressing the s button
again, 00:00 appears in the display. The pulse duration is identified
by the symbol B.
h Enter minutes
m Enter seconds
Pulse switching points (with set pulse duration) and
normal switching points can be entered in any sequence.
To do this, press the s button again.
If a normal switching point already entered is subsequently identified as a pulse switching point through marking with the l button,
the following switching points then move down, and a pulse duration is inserted. This appears in the display when next pressing the
s button. If all memory locations are occupied, subsequent
conversion into a pulse switching point will be rejected.
5.3 Pulse function P3 (only on the Two-channel timer)
A pulse sequence can be programmed for channel B which can be
started or stopped manually or via channel A.
Setting pulse function P3 - see Table 1.
Setting the pulse sequence:
Only switch-on or switch-off pulses of 00:00 min to 59:59 min can
be entered for channel B. The entry of normal switching points is
restricted.
Setting a pulse sequence for channel B is initiated by pressing the
s and a buttons.
The symbol B in the display indicates that the entry of a pulse
duration is expected.
h Set minutes
m Set seconds
After entering the switch-on pulse duration, the entry of a switch-off
duration is expected after pressing the s button again. A sequence of alternating switch-on and switch-off durations forms a
pulse sequence.
Starting and stopping a pulse sequence manually
A pulse sequence entered for channel B is started by pressing the
l button.

The entries form, for example, a
pulse sequence which, after starting,
activates channel B for 00:15 min,
deactivates it for 00:15 min, activates it for 00:01 min, deactivates it
for 00:04 min, etc.
Table 2
The pulse sequence is repeated ad infinitum until stopped by
pressing the l button again.
Channel B remains in the switching mode just adopted. On pressing the l button again, the pulse sequence recommences from
the beginning.
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
switching points, with additional pressing of the l button marking
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 pulse sequence
on channel B.
An impulse sequence started via a pulse switch-on point can be
stopped by manually pressing the l button. Conversely, a pulse
sequence started manually can be stopped by a pulse switch-off
point. The pulse sequence always starts from the beginning.
Deleting switch-on and switch-off pulses
Press s, then the a button. Then press h repeatedly until
−−:−− appears in the display. Pressing s again enables the next
pulse duration to be deleted in the same way.

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).
On Two-channel timers the astronomical switching
functions can only be executed with channel A.
6.1 Selecting the astronomical function
6.3 Astronomical function A2
The time switch provides 5 astronomical functions.
For setting: see Table 1, point 4.5
Longitude and latitude: the twilight times depend on the geographical 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 for Central Europe.
The value must be changed corresponding to the place of operation.
Function A2 enables the switching on of a consumer item after
dusk or before dawn for a desired period of time.
The period during which the consumer item (e.g. a light) is
switched on after dusk is determined by the evening time differential. The morning time differential determines the duration of
switch-on time before dawn (see Table 1).
If one of the switching sequences is not to be executed in the
evening or morning, the corresponding time differential must be set
at 0:00.
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 s button:
The time is displayed, the colon flashes.
s The dawn switching point is displayed.
Pressing s again displays the dusk switching point.
The date must be entered when using the automatic
summer/winter time switchover and astronomical functions. If the astronomical function is deactivated (= A0),
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 of
the twilight switching points to be advanced or retarded. In the
case of a negative differential value, the switching point is activated correspondingly earlier, with a positive value correspondingly
later. To change the programmed default settings,
see Table 1.
Activating astronomical function A1 makes additionally
set switching points ineffective. This applies to the Onechannel timer as well as channel A of the Two-channel
timer.
Activating astronomical function A2 makes additionally
set switching points ineffective. This applies to the Onechannel timer as well as channel A of the Two-channel
timer.
6.4 Astronomical function A3 (AND-linked)
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-switching
points.
ON-switching point switches ON
OFF-switching point switches OFF

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 switching point is ignored, and the consumer item is not switched on.
Example 2

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 programmed 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 consequence of this for channel A is that the switch-on phases overlap.

In example 1, the time switch goes by the programmed switching
points and in Example 2, by the twilight times.
6.6 Astronomical function A5
Function A5 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 switched off with the next switching point on
the following day, not by the dawn.

Example:
Default value for cycle correction: +2 sec per 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).
Setting cycle error correction
Cycle error correction can only be set when mains voltage
is connected.
Cycle correction value: the cycle precision of the time switches at
room temperature (20° C) is generally better than 1 second per
day. Higher ambient temperatures, however, can cause an additional 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 deviation 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 conditions of approx. 20 °C. The newly ascertained cycle deviation must
be added to or subtracted from the default value.
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).
