Counting Up/Down (Counter) {Cnt; Counting Direction Setting {Cdir; Counting Limit Setting {Lm_D}, {Lm_H}, {Lm_M}, {Lm_S - Elen NDC 57/4 R L20 User Manual

The resetting of the stopwatch is done by the RESET button, but in order to do that, the time measurement
must be stopped (stop condition after pressing the STOP ■ button).
5.7.1.2 Control of the stopwatch by a local button (TRIGGER INPUT)
The local button must be connected to the TRIGGER INPUT, see the connection diagram. This method of
control only supports the START and PAUSE functions, which are implemented by a short pressing of the
button (< 2.5 seconds). To activate the RESET button, you need to keep the button depressed for more than
2.5 seconds.
Let us assume a reset state of the stopwatch (00:)00.00 (after switching on or reset). Short pressing of the
button will start a time measurement (intermediate time), while the measurement will keep running in the
background (PAUSE). After the next pressing of the button, the measured time will be displayed again
(START), and so on.
The resetting of the stopwatch is done by a long pressing of the button in the PAUSE state.
5.7.1.3 Control of the stopwatch by a remote button
The remote button must be connected to the NDC-net and its address must be allocated to the clock/stopwatch
that is to be controlled by it, see chapter 5.6.5 Allocation of the remote button, address setting {PbAd}.
The stopwatch is controlled in the same way by the local button.

5.8 Counting up/down (Counter) {Cnt}

The counter allows to work in one of two modes, specifically the UP mode or the DOWN mode. In the UP
mode, the counter counts the time from the value (00:)00:00 up until a preset value. In the DOWN mode the
counter counts the time from the set value downwards to (00:)00:00. When the end of the interval is reached,
the built-in relay is switched on, while the duration of the switch-on state can be adjusted. In the settings it is
also possible to choose whether after ending the counting up/down the whole cycle is started again and how
the time counting should behave when the internal time setting is changed from outside.
During counting up/down, time is shown in the following format:
a) NDC xxx/4
DD . HH
HH : MM
MM : SS
SS
b) NDC xxx/6
DD . HH : MM
HH : MM : SS
MM : SS
SS
A detailed description of the above properties is contained in the following chapters, so please read them
carefully.
5.8.1

Counting direction setting {Cdir}

({MEnu}→){Cnt}→{Cdir}
To count time up, please select the UP mode [the counting starts on (00:)00:00 and ends on a preset limit], to
count time down, choose the DOWN mode [the counting starts on a preset limit and ends on (00:)00:00].
Setting of the count direction (mode):
{Cdir} (counting direction) {uP}/{dn}
The {uP}/{dn} values are switched between by the ◄/► buttons and confirmed by the OK button.
5.8.2

Counting limit setting {LM_d}, {LM_H}, {LM_M}, {LM_S}

({MEnu}→){Cnt}→{LM_d}
({MEnu}→){Cnt}→{LM_H}
({MEnu}→){Cnt}→{LM_M}
({MEnu}→){Cnt}→{LM_S}
In this menu, the start or end value of the limit is set (according to the selected counting direction). The limit is
in the format: days:hours:minutes:seconds (DD:HH:MM:SS), while individual items are set separately.
For the setting, in the main menu it is necessary to activate the {Cnt} item and confirm it by the OK button (see
chapter 5. SETTING, CONTROLLING AND PROGRAMMING OF THE NDC CLOCKS).
