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.

3.3. Adjustment
The DT9100 I4 can e adjusted through the 3 front panel
mem rane keypad. The instrument doesn’t need any
internal adjustment.
All settings are stored in a attery ack-up RAM.
At first installation you have to set the time and other
working parameters what you need.
At attery replacement the settings are kept for min. 1 hour.
3.4. Storage and transport
This instrument should e stored and transport in places
whose climatic conditions are in accordance with Chapter
10.1. Technical specifications, as descri ed under the title:
Environmental conditions.
The packaging of DT9100 I4 consist of enviroment-friendly,
recycla le card oard is used to protect the instrument
against the impacts of normal stresses occurring during
transportation. The corrugated card oard ox is made from
environment-friendly, recycla le paper. The inner protective
material is polyfoam and nylon, which should e disposed of
via specialised recycling companies.

4. Mounting
4.1. General instructions
After the dismount of front panel e careful that do not get in
foreign material to inside of device.
When mount of front panel e careful the seal, ecause if
you mount the seal in wrong position, the enclosure may get
wet!
When mounting DT9100 I4 as panel instrument, use the
enclosed seal to assure IP 65 protection etween the
instrument and the panel on the front side (only for the
panel-mounted version).
Electrostatic hazard! Clean only a moist cloth and
detergent.
Mounting positions The device can e mounted any position.
Select a mounting position: where you can easily read the
display, which is accessi le for mounting and connecting
the instrument, and which minimises the hazard of water,
dust or dump getting into the instrument.
The recommended mounting position is same like in capter
4.2. Main dimensions of the instrument.
Mounting cable entries The instrument is equipped with one M16x1.5 ca le entry
and one additional hole equipped with sealing plug. One
M16x1.5 ca le entry are accessories. If more than one
ca le entry is required (see chapter 5.), take out a sealing
plug y turning it in an anticlockwise direction. To put in a
ca le entry, use a sealing ring and turn the ca le entry in a
clockwise direction. Tighten the screws as much as
necessary to ensure the desired sealing. Use only
appropriate tools.
