3 Function Principle
This chapter describes the function principle of the Network Clock Device 8030NTS/NCD and
the internal relations between the different functional groups.
3.1 Block Diagram
•Internal Supply Voltage
The individual functional components are supplied with the required operating voltage
via the implemented power supply unit.
•Time Information
The Module 8030NTC provides the time information and the according synchroniza-
tion status to Module 8030NTS/M. This time and status information is used for syn-
chronization of the NTP service and if applicable other signal generations and network
protocols running on 8030NTS/M.

3.2 Function 8030NTC
The Module 8030NTC acts as a network time client. A complete LINUX operating system is
running on this Module providing all functions such as NTP, WebGUI etc.
By means of selected network time protocols (NTP or PTP) the module-internal crystal is going
to be adjusted. Thus, a highly precise time base for module 8030NTS/M –and if necessary
further signal generators –will be generated.
3.3 Function 8030NTS/M
The Module 8030NTS/M acts as a network time server. A complete LINUX operating system
is running on this Module providing all functions such as NTP, WebGUI etc.
Module 8030NTS/M will be adjusted based on the time information delivered by module
8030NTC and provides this time information to all other activated network time services.

4 System Behaviour
This chapter describes the behaviour of the system in special operational phases and condi-
tions.
4.1 Boot Phase
The boot process of the Network Clock Device 8030NTS/NCD starts after turning on the sys-
tem or a reset.
During the boot process the Modules 8030NTC and 8030NTS/M boots its operation system
and is therefore not available via LAN.
The end of the boot process is reached when the LED test of the operation LEDs in the front
panel has finished. The boot process lasts approx. 1-1.5 minutes.
4.2 Adjustment Process
During boot process the activated synchronization service (NTP or PTP) will automatically be
started on module 8030NTC. After starting the synchronization service module 8030NTC re-
quires approx. 5 –10 minutes to be adjusted.
After adjusting the synchronization service of module 8030NTC, the module provides a valid
sync status for module 8030NTS/M, whereby module 8030NTS/M synchronizes based on this
time information of module 8030NTC. This process can last approx. 5 –10 minutes too.
After synchronizing module 8030NTS/M will be available as network time server.
4.3 Firmware Update
Modules 8030NTC and 8030NTS/M can be updated mutually independent.
Detailed information can be found in the module specific technical manuals of the modules
8030NTC and 8030NTS/M.
4.4 Activation of Functions (Activation Key)
There are individual, mutually independent activation keys available for module 8030NTC and
8030NTS/M depending on the serial number of the module where the functionality is intended
to be activated.
Detailed information can be found in the module specific technical manuals of the modules
8030NTC and 8030NTS/M.

5.3.1.4 Voltage Input / Fuse Protection
The 100-240V AC connection is made via the pluggable screw terminal L, N and .
Primary Side Fuse Protection
The device must be installed in accordance with the provisions of EN 60950. There must be a
suitable isolating device external to the power supply capable of switching the device off.
The primary side line protection, for example, is suitable for this purpose.
Further equipment protection is not required because the device is fused internally.
Recommended External Fuse
When connecting the Network Clock Device 8030NTS/NCD a suitable fuse protection of the
power supply needs to be observed.
Accordingly, the performance data should be taken from the nameplate of the device. Cur-
rently the standard versions of the Network Clock Device 8030NTS/NCD are supplied with
power supplies with power consumption between 6 and 15VA.
Regarding DC applications a suitable fuse must be connected.
If the internal fuse trips it is highly likely that the device is faulty. In this
case the equipment should be checked at the factory!
5.3.1.5 Power Supply Specifications
All specifications regarding the AC power supply can be found in Chapter 11.3 Power Sup-
plies.
