2.2 Display
The height of the display elements is 57, 100, 160 or 212 mm (readability up to 23, 40, 70 and 100 m
respectively). NDC 57/x and NDC 100/x types use superbright 7-segment LED modules. Other LED colours
are possible by agreement for an extra fee. NDC 160/x and NDC 212/x types use superbright elliptic LEDs to
ensure their legibility even in direct sunlight (outdoor).
2.3 Synchronisation, precision
•
Possibility of external time synchronisation by means of synchronisation modules (e.g. GPS receiver).
Time display precision:
•
–
Autonomous time: ±30sec/month (in +20°C ÷ +30°C temperature range);
–
When an external synchronisation module is connected, the precision is given by the precision of the
synchronisation.
2.4 Inputs, outputs
RS485 interface with galvanic isolation for the interconnection with other devices in an NDC-net.
•
An input for the connection of a local button with or without galvanic separation for controlling the stop
•
watch/counter. The maximum length of the local button's cable is 3 – 5 m (according to the level of
interference).
An input for the connection of a local thermal sensor (2 m as standard, or up to 5 m max. as per request)
•
Built-in output relay 2 A/250 VAC, which can be closed for 0.1 s – 99 s in the counter mode when the setup
•
limit is reached or as the output of the switch clock.
•
GPS Time Receiver input.
2.5 Settings
Time setting manual, wireless via an IR controller or automatic, when an external synchronisation module
•
is connected.
Manual or automatic LED brightness control based on the external illumination.
•
•
Programming and setting of the clock via a wireless IR controller (max. perpendicular distance 15 m):
− Time and date setting;
− Activation of selected display modes (time, date, temperature, stop watch, counter, remote sensor) –
intervals of alternating data display;
− Limit and modes for the counter;
− Stop watch format;
− Stop watch and counter control;
− Enabling/disabling of daylight saving time (DST);
− Time shifting in the range ±23 hrs 59 min – correct displaying of times in different time zones with external
synchronisation;
− Manual time setting;
− Counter relay switch-on time setting;
− Selection of a local or remote sensor 1 in an NDC-net to be displayed;
− Selection of a local or remote sensor 2 in an NDC-net to be displayed;
− Selection of the remote input in an NDC-net (only the Master clock, see chapter 2.9 NDC-net
communication network below);
− Interval of synchronisation with other clocks in the NDC-net (only the Master clock);
− Switching clock – times and periods of switching-on the internal relay, weekly calendar.
