5.8.6.1 Controlling the counter by a remote controller
The counter is started by pressing the
START
► button. If, during the counter’s running, no control button is
depressed, the counter will count up to the value of the set limit (in the UP mode) or down to (00:)00:00 (in the
DOWN mode). If automatic starting restarting of the counter is enabled ({CrPt} item), when the counter reaches
the limit, it will be started again from the beginning.
If you depress the
PAUSE
▐ ▌
button when the counter is running, the display will “freeze” the current value of
the counted time (intermediate time), while the counting up/down of the time runs in the background. After
pressing the
START
►again, the display will display the time counted up/down.
If you press the
STOP
■
button during the counter’s running, the display will show the current value of the
counted time and stop the counding up/down. The pressing of the
STOP
■ button during the dispaying of the
intermediate time (i.e. after previous depressing of the
PAUSE
▐ ▌
) the counting up/down of the time that was
running in the background will stop and the resulting time will be displayed.
If the counter is in the “stop” condition, it is possible to start it again with the
START
►button from the time it
displays.
The counter’s reset is done by pressing the
RESET
button, the counting up/down of hte time, however, must
be stopped (stop condition after pressing the
STOP
■ button).
5.8.6.2 Controlling the counter by a local button (TRIGGER INPUT)
The local button must be connected to the TRIGGER INPUT, see the connection diagram. This method of
controlling supports only the START and PAUSE functions, which are implemented by a short pressing of the
button (< 2.5 sekunds). For the RESET function it is necessary to keep the button depressed for more than
2.5 seconds.
Let us assume the initial state of the counter after power on or after a reset, showing (00:)00:00 (for counting
up) or the preset limit (for counting down). A short depressing of the button will start the time counting (START),
a short repeated depressing will “freeze” the current value of the counted up/down time on the display
(intermediate time), while the counting up/down of the time runs in the background (PAUSE). By further
pressing of the button, the display will show again the counted up/down time (START), and so on.
The counter’s reset is done by a long depressing of the button in the PAUSE state.
5.8.6.3
Controlling of the counter by a remote button
The remote button must be connected into the NDC-net and its adddress must be allocated to the clock/counter
that is to be controlled by it, see chapter
5.6.5 Allocation of the remote button, address setting {PbAd}
.
The counter is controlled in the same way as in the case of a local button.
5.9 Switch clock, time interval programming {PrG}
The clock allows to set up to 16 times of switching on the output relay in a single day, the period of the switch-
on state of the relay and a weekly calendar when the switching is active. In order to switch on the relay, the
following conditions have to be met:
1. The switch on time has arrived and;
2. The relay switch on period > 0 s and;
3. The day given in the weekly calendar is set as active.
If at least one of the above conditions is not met, the relay will not switch on!
The programming of the time intervals is first necessary to activate in the main menu by the {PrG} item and
then confirm it with the
OK
button.
5.9.1 Setting the switch on times {S_tM}
({MEnu}→){PrG}→{S_tM}→{tM0}→...→{tM15}
In this part of the menu you can set up to 16 times, {tM0} through {tM15}, at which the output relay of the clock
will be activated for the required period. When choosing the {S_tM} item, set the time of swithing on that is to
be set with the arrow buttons ▲ / ▼. After confirming with the
OK
button you can enter the required value.
{tM0}
Relay switch on time 00:00 through 23:59 (HH:MM)
default 00:00;
...
...
...
{tM15}
Relay switch on period 00:00 through 23:59 (HH:MM)
default 00:00.
The switch on time is set in minutes. It is suitable to occupy the sequence starting from {tM0}.
