3.2. Principle o operation
Area o application DT9100 I4 is an intrinsically safe digital clock ena le
accurate time to e displayed in even the most hazardous
plant areas: Zone 1, 2 or in the safe area.
Synchronising function allows the clock to e synchronised
with a master clock. The clock can e synchronise through
the current loop. When the loop current is over 12 mA the
clock stop going when the loop current decrease under
8 mA the clock will re-start from a new time selected in the
programme menu. This may e the nearest minute or the
nearest hour of the original display or a preset time may e
entered during programming.
The DT9100 I4 has two isolated digital outputs, which can
e used for alarm signaling or for synchronising other
clocks.
DT9100 I4 is housed in a moulded polycar onate case
hauseproof to IP65 for installation in the field or on the
control panel.
Operating principle The clock incorporate a high accuracy temperature
compensated time ase, which is processed y a
microcontroller. The microcontroller produces the real time,
in 24 hour HH:MM format, drives the large 4 digit 25,4 mm
height LCD display, process the front panel keypad, the
synchronising inputs, and drives the digital outputs. The
settings and the actual time are stored in a memory which
stores it’s content for cca. 1 hour for ridging the supply
current failure. The clock also going for cca. 1 hour at this
case.
Power supply DT9100 I4 is loop-powered from 4–20 mA synchronising
signal, dropping less than 2,2 V.
It is not recommended to ring the supply current elow
8 mA.

4.3. Mounting as a wall-instrument
Removing the ront
cover
In order to remove the front cover, first remove the four
fixing screws as shown in the drawing. A screwdriver of
appropriate head-size should only e used. Using
screwdrivers with an inappropriate head-size may cause
damage to the screws’ heads or to the instrument front
panel.
Remove the screws y turning them in an anticlockwise
direction as shown in the drawing Step (1). The screws are
secured against falling out. After this, you can simply take
away the front cover from the housing (2) and you can
open the housing y turning the cover downwards (3).
Plastic ties are used for fastening the front cover to the
housing in order to prevent it from falling down.

Preparatory steps There are four through-holes, shown y arrows in the
following drawing, for the fastening of the housing. The
diameters of the holes are made for M3 screws.
Holes or mounting
1. Mark the places of the holes in accordance with the
drawing.
2. Make the holes ready for mounting.
3. Remove any urrs from the ready-made holes.
Please o serve the safety rules throughout the operation.
20180905-V1 13

DT9100 I4
Mounting the instrument Four M3 threaded screws are needed for mounting the
instrument (these are not accessories). The type of the
screws depends on the wall-material, while the dimensions
depend on the wall-thickness. The use of cross recessed
pan head screws is recommended to make the mounting
easier. The minimum screw-length should e the wall-
thickness + 10 mm.
During mounting, please o serve all safety rules, and use
only appropriate tools.
Secure the screws against getting loose. For this purpose
you may use spring lock or serrated lock washers.
Depending on the material of the wall, and in order to
ensure the most practica le mounting method, it is not
mandatory, of course, to use the a ove-descri ed threaded
joints. Depending on the situation, special screw types for
wood or for metal sheets can also e used, or the joint can
e riveted too.
Mounting the ront cover
back to its place
1. Check if there are alien materials left in the housing, like
small tools, wire or metal pieces, plastic chips, etc. If there
are, remove them.
2. Put ack the front cover of the instrument, taking care
that the sealing should get to its place. There should e no
gap, nor ca les caught etween the housing and the front
cover.
3. Tighten the front cover.
Turn the screws in clockwise direction. Tighten the screws
so much that ensures the desired sealing.

5. Connecting
5.1. Preparing the connection
Always o serve the following safety instructions:
• When you are going to install instruments in a hazardous
area, or install instruments which are connected to
instruments working in a hazardous area, you should take
note of the appropriate regulations, and conformity and type
approval certificates of the DT9100 I4 and the other
instruments (e.g. isolator, Zener arrier).
• The connection must e carried out y trained and
authorized personnel.
• In particular, make sure that no potential equalization
currents flows over the ca le screen. Ground only one side
the ca le screen.
• Use only a screwdriver with appropriate head.
• Do not touch the wire ends to each other.
Select the connection
cable
Use two wire twisted pair screened ca le.
The wire cross-section should e 0.25–1.5 mm2.
You may use either solid conductor or flexi le conductor.
In the case of using flexi le conductor, use crimped wire
end.
When select the ca le, consider the Ex installation
regulations.
EMC considerations In installation must e ensured, that no potential
equalization currents flows over the ca le screen.
Ground only one side the ca le screen (it’s recommended
the transmitter side). If necessary of grounding on oth
sides (for suppress very high level, high fequency
interference signals) this can e achieved y use separate
potential equalization or y use of a locking capacitor (e.g.
ceramic capacitor 1 nF, 1500 V) or. The low frequency
potential equalization currents are thus suppressed, ut the
protective effect against high frequency interference signals
remains.
Choosing the value of the capacitor should take consider
the Ex installation regulations.
20180905-V1 17

DT9100 I4
The DT9100 I4 has a very powerful EMC protection, so
grounding and practice on oth sides are generally
unnecessary, ut when a particularly high electrical
distur ance device (such as an inverter drive system) is
used near y, it may e necessary to use the a ove. An
important rule is that the signal ca les, separate from the
power ca le.
Number o cables It is recommended to trace the synchronizing 4-20 mA
current loop with a separate shielded ca le and digital
outputs on another ca le. To reduce electromagnetic
distur ance to the device, it is imperative to install the
wiring shown on the previous pages and to form the shields
as shown in the diagram.
A common ca le can only e used, if the insulation
strength etween the wires is 500 V or higher!
Cables entries 1. Check the conformity of the ca les as descri ed in the
Ca les Selection section.
2. Prepare the ca le for connection. The uninsulated wire
end length should e 8 mm.
3. Remove the front cover of the device as descri ed in
capter 4.3.
4. Loosen the clamp nut on the ca le gland so that the
ca le can e easily inserted. (Do not wrap it down
completely, as it may e lost and the sealing ring may e
lost.)
5. Route the ca le through the ca le gland into the housing
so long that it can easily loosen the ca le tie. (The excess
length can e retracted at the end of the operation.) Make
sure the ca le does not damage the device.
