3.2. Principle of operation
Area of application DT9102 B is an intrinsically safe digital clock which enables
accurate ti e to be displayed in even the ost hazardous
plant areas: Zone 1 and 2 or in safe areas.
Synchronising function allows the clock to be synchronised
with a aster clock. Connecting synchronising ter inals
together will stop the clock. When the ter inals are
disconnected the clock will re-start fro a new ti e
selected in the progra e enu. This ay be the nearest
inute or the nearest hour of the original display or a
preset ti e entered during progra ing.
The DT9102 B has two isolated digital outputs, which can
be used for alar signalling or for synchronising other
clocks.
The clock is powered by a replaceable intrinsically safe
battery pack.
DT9102 B is housed in a oulded polycarbonate case in
co pliance with IP65 for installation in the field or on a
control panel.
Operating principle The clock incorporates a high accuracy te perature
co pensated ti e base, which is processed by a
icrocontroller. The icrocontroller produces real ti e in
24 hour HH:MM for at, drives a large 4 digit 25.4
height LCD display, processes the front panel keypad and
the synchronising inputs, and drives the digital outputs.
The settings and the actual ti e are stored in a e ory
which stores its content for ini u 15 inutes for
bridging the battery exchange ti e. The settings can be
done by tree front panel buttons.
The device is operational for at least 15 inutes even if the
power supply is re oved.
Power suppl The device does not need external power.
Power supply is DT4V5BAT type battery pack.
The battery pack provides the energy for ini u two
years.
Attention! The DT9102 B is powered by only DT4V5BAT
type intrinsically safe replaceable battery pack
( anufactured by Datcon Kft.)!
Do not recharge!
The battery replace ent can be acco plishes even in a
hazardous area.

5. Connecting
5.1. Preparing the connection
Always observe the following safety instructions:
• When you are going to install instru ents in a hazardous
area, or install instru ents which are connected to
instru ents working in a hazardous area, you should take
note of the appropriate regulations, and confor ity and
type approval certificates of the DT9102 B and the other
instru ents (e.g. isolator, Zener barrier).
• The connection ust be carried out by trained and
authorized personnel.
• In particular, ake sure that no potential equalization
currents flows over the cable screen. Ground only one side
the cable screen.
• Use only a screwdriver with appropriate head.
• Do not touch the wire ends of the battery pack to each
other.
Select the connection
cable
Use two wire twisted pair screened cable.
The wire cross-section should be 0.25–1.5 2.
You ay use either solid conductor or flexible conductor.
In the case of using flexible conductor, use cri ped wire
end.
When select the cable, consider the Ex installation
regulations.
EMC considerations In installation ust be ensured, that no potential
equalization currents flows over the cable screen.
Ground only one side the cable screen (it’s reco ended
the trans itter side). If necessary of grounding on both
sides (for suppress very high level, high fequency
interference signals) this can be achieved by use separate
potential equalization or by use of a blocking capacitor (e.g.
cera ic capacitor 1 nF, 1500 V) or. The low frequency
potential equalization currents are thus suppressed, but the
protective effect against high frequency interference signals
re ains.
Choosing the value of the capacitor should take consider
the Ex installation regulations.
14 20180905-V120180905-V1

DT9102 B
The DT9100 B has a very powerful EMC protection, so
grounding and practice on both sides are generally
unnecessary, but when a particularly high electrical
disturbance device (such as an inverter drive syste ) is
used nearby, it ay be necessary to use the above. An
i portant rule is that the signal cables, separate fro the
power cable.
Number of cables It is reco ended to trace the synchronizing contact with a
separate shielded cable and digital outputs on another
cable. To reduce electro agnetic disturbance to the
device, it is i perative to install the wiring shown on the
previous pages and to for the shields as shown in the
diagra .
A co on cable can only be used, if the insulation
strength between the wires is 500 V or higher!
Cables entries 1. Check the confor ity of the cables as described in the
Cables Selection section.
2. Prepare the cable for connection. The uninsulated wire
end length should be 8 .
3. Re ove the front cover of the device as described in
capter 4.3.
4. Loosen the cla p nut on the cable gland so that the
cable can be easily inserted. (Do not wrap it down
co pletely, as it ay be lost and the sealing ring ay be
lost.)
5. Route the cable through the cable gland into the housing
so long that it can easily loosen the cable tie. (The excess
length can be retracted at the end of the operation.) Make
sure the cable does not da age the device.

Connecting the cables
into the terminal
assemblies
Make sure before connection that the power supply is
switched off.
The push-in direct connector asse blies used allow a fast
connection of the cables.
Their proper usage is shown by the following figure:
1. Push the stripped cable-end until it possible into the
ter inal asse bly. In the case of flexible cable-ends, you
can facilitate opening the connection part by pushing down
the white button.
2. By pushing the wire in, the self-closing connection is
being established. Check it by pulling it outwards slightly.
(3. When you disasse ble the cable, push down the white
button by a screwdriver, and pull the cable-end out.)
There is no need to use great force for pushing the cable
in, neither for re oval. The button can be pushed down
easily. Please do not exercise forces higher than
necessary, as it ay cause da ages to the ter inal
asse bly.
