3.2. Principle of operation
Area of application DT9102 I4 is an intrinsically safe digital clock enable
accurate time to be displayed in even the most hazardous
plant areas: Zone 1, 2 or in the safe area.
Synchronising function allows the clock to be synchronised
with a master clock. The clock can be 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 be the nearest minute or the
nearest hour of the original display or a preset time may be
entered during programming.
The DT9102 I4 has two isolated digital outputs, which can
be used for alarm signaling or for synchronising other
clocks.
DT9102 I4 is housed in a moulded polycarbonate 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 base, which is processed by 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 bridging the supply
current failure. The clock also going for cca. 1 hour at this
case.
Power supply DT9102 I4 is loop-powered from 4–20 mA synchronising
signal, dropping less than 2,2 V.
It is not recommended to bring the supply current below 8
mA.

3.3. Adjustment
The DT9102 I4 can be adjusted through the 3 front panel
membrane keypad. The instrument doesn’t need any
internal adjustment.
All settings are stored in a battery back-up RAM.
At first installation you have to set the time and other
working parameters what you need.
At battery replacement the settings are kept for min. 1 hour.
3.4. Storage and transport
This instrument should be stored and transport in places
whose climatic conditions are in accordance with Chapter
10.1. Technical specifications, as described under the
title: Environmental conditions.
The packaging of DT9102 I4 consist of enviroment-friendly,
recyclable cardboard is used to protect the instrument
against the impacts of normal stresses occurring during
transportation. The corrugated cardboard box is made from
environment-friendly, recyclable paper. The inner protective
material is polyfoam and nylon, which should be disposed of
via specialised recycling companies.

4. Mounting
4.1. General instructions
Use the enclosed seal when mounting DT9102 I4 on panel
to assure IP 65 protection between the instrument and the
panel from the front side (only panel mounting version).
Electrostatic hazard! Clean only a moist cloth and
detergent.
Mounting positions
Select a mounting position you can easily read the display
reach for mounting and connecting the instrument and that
minimises the hazard of water, dust or dump getting into the
instrument.
Mounting cable entries
The insrument is equipped with one M16x1.5 cable entry
and one additional hole equipped with sealing plugs. One
M16x1.5 cable entry is accessory. If required more than one
cable entry (see chapter 5.) put out the sealing plug turning
it in anticlockwise direction. To put in the cable entry use the
sealing turn it in clockwise direction. Tighten the screws so
much that ensures the desired sealing. Use only appropriet
tools.
