PROPERTIES
2.1 Display functions
Time (display format)
•
− HH:MM
(Hours:Minutes)
− HH:MM:SS
(Hours:Minutes:Seconds)
Date (display format)
•
− DD:MM
(Day:Month)
− DD:MM:YY
(Day:Month:Year)
Temperature* (display format)
•
− -99° ÷ -10° ÷ -9.9° ÷ 99.9°
− -99°C ÷ -10°C ÷ -9.9°C ÷ 99.9°C
− A local thermal sensor (i.e. connected directy to the clock) can be located near the NDC or as part of
the frame (for extra fee). The precision of the displayed temperature is given by the precision of the
sensor.
* if a local thermal sensor is connected
Stop watch
•
− SS.ss –> MM:SS
Seconds.hundredths of seconds with automatic switching to Minutes:Seconds when the seconds are
full;
− MM:SS.hh -> HH:MM:SS
Minutes:Seconds.hundredths of seconds with selectable automatic switching to Hours:Minutes:Seconds
or a 99-minute mode (MM:SS.hh)
− Functions: START, STOP/FREEZE (intermediate time, the measured time runs in the background),
RESUME, RESET ;
− Automatic restart of the stop watch when the maximum displayable time is reached;
− Remote control of the stop watch, external contact (with or without galvanic separation) or with a remote
button in the NDC-net.
Counter (counting up/down)
•
− Automatic switching of the display format, range: 1 s to 99 days, 23 hours, 59 minutes, 59 seconds;
− COUNT-UP or COUNT-DOWN mode – adjustable limit;
− Functions: START, STOP/PAUSE, RESUME, RESET;
− Single or repeated run of the counter when the setup limit is reached;
− Switchable counter time correction due to a time change (new time setting) or external time
synchronisation;
− Control of the counter via a remote control, an external contact (with or without galvanic separation) or
a remote button in the NDC-net;
− Possibility to switch on either the internal or a remote relay (close contact) when the limit is reached.
Switch clock (time interval programming)
•
− Programmable 16 intervals of switching on the output relay in a single day;
− Setting of the relay switch on period from 0.01 – 99 sec;
− Weekly calendar, setting of switch-on days (from Sunday to Saturday).
Data from remote sensors (in NDC-net)
•
− Possibility to display data from 2 remote sensors connected to the NDC-net (e.g. external temperature
sensor, humidity sensor, pressure sensor, ...). It is possible to set on the clock the remote sensors whose
data will be displayed. If a local thermal sensor is connected, then it is possible to display just one figure
from a remote sensor.
The clock allows alternate display of the above data, while the user has the possibility to program the
•
duration of their displaying in the range 0 ÷ 60s (0
Automatic (depending on ambient light conditions) or manual brightness setting in 15 levels.
