1 – Display;
2 – Button ▲ (up), is used for upward scrolling or increasing of parameter
value;
3 – LED indicator of load relay state (lights on – when the load relay is on,
lights off – when the load relay is off);

Figure 3.2 – Timer front panel
All settings of the timer are made with the help of the buttons. The current time and timer state are shown on
the display, and the state of load relay is shown with the help of LED indicator.
3.1.3 Real time clock
Timer is equipped with an integrated real time clock with internal power supply (in case of main power supply
loss) from reserve power source – a lithium battery element.
Attention – Prior the use of the timer it is necessary to set the exact date and time.
3.2 OPERATIONAL MODE
3.2.1 The operational mode of the timer is based on switching on/off of load relay under one of the userdefined programs Pх (х – Program number from 1 to 2), which are set separately.
Each program Px can be set to one of the modes:
 Astronom;
 Week;
 Daily;
 Simple.
For each operational mode the user can assign the independent events. In the timer there can be assigned
maximum 500 events which can be distributed for all programs (P1 and P2) and operational modes.
3.2.2 Astronom mode
As an event the user assigns the state of load relay (on or off) and a shift of time in reference to the sunrise
and sunset (from -23:59 to +23:59).
Every day the timer calculates the real time of sunrise and sunset, sums this time with the time of event, and
then the resulted time is referenced with the clock of real time and if the resulted time is more or equal to real time
REV-303
NOVATEK-ELECTRO
~5~
– the time will switch the load relay in state which is assigned by the event.
The above described algorithm is performed for each event planned by the user. In case when there are more
than 1 event planned, only the event which corresponds to the real time clock will be activated, other events will
not be performed.
At the latitudes where there is a polar day, the events concerning the sunset will not be performed and the
time of the sunrise is taken as equal to 00:00.
At the latitudes where there is a polar night the events concerning the sunrise will not be performed, and the
time of the sunset is taken as equal to 00:00.
In figure 3.3 there is resulted a case of Program P1 being set for the astronomic mode of work with four
events for a street illumination during 4 hours at sunset and 4 hours at sunrise, the rest of the time the illumination
is switched off.
Figure 3.3 – Street illumination as an example of astronomic mode of work
3.2.3 Week mode
As an event the user assigns the state of load relay (on or off), a day of the week (since Mo through Fr) and
the time (from 00:00:00 to 23:59:59).
The day of the week and time of the event are referenced with the integrated clock of real time, and if they are
equal or the event time is more than the real time – the time will switch the load relay in state which is assigned by the
event.
The above described algorithm is performed for each event planned by the user. In case when there is more
than 1 planned event, only the event which corresponds to the real time clock will be activated, other events will
not be performed.
In figure 3.4 there is resulted a case when Program P1 is set for the weekly mode of work, when each day at
certain time there is switching on and switching off of the load relay.
Figure 3.4 – On and Off of a loading relay as an example of the weekly mode of work
3.2.4 Daily mode
As an event the user assigns the state of load relay (on or off) and the time (from 00:00:00 to 23:59:59).
The time of the event is referenced with the integrated clock of real time, and if they are equal or the event
time is more than the real time – the time will switch the load relay in state which is assigned by the event.
The above described algorithm is performed for each event planned by the user. In case when there is more
than 1 planned event, only the event which corresponds to the real time clock will be activated, other events will
not be performed.
In figure 3.5 there is resulted a case when Program P1 is set for daily mode of work with six events.
3.2.5 Simple mode
As an event the user assigns the state of load relay (on or off) and the time (from 00:00:00:0 to 23:59:59:9).
The time of the event is referenced with the integrated counter that starts counting since the moment of
providing the power supply to the timer, and if they are equal or the event time is more than the time of integrated

The above described algorithm is performed for each event planned by the user. In case when there are more than
1 event planned, only the event which corresponds to the real time clock will be activated, other events The above
described algorithm is performed for each event planned by the user. In case when there is more than 1 event planned,
only the event which corresponds to the integrated counter will be activated, other events will not be performed.
In figure 3.6 there is resulted a case when Program P1 is set for the simple mode of work with six events. In
this mode after providing the power supply there is a performance of a simple list of events.
