instructions and with the electromagnetic compatibility and safety regulations
and standards applicable to the type of installation.
In the installation with control and measurement instruments exists, in case of
leakage, a risk to personnel on the side where the medium is under pressure.
All safety and protection requirements must be observed during installation,
operation and inspections.
If a device is not functioning correctly, disconnect it and send it for repair to the
manufacturer or to a firm authorised by the manufacturer
In order to minimise the risk of malfunction and associated risks to personnel, the
device is not to be installed or used in particularly hostile conditions, where the
following risks occur:
Possibility of mechanical impacts, excessive shocks and vibration;
Excessive temperature fluctuation;
Condensation of water vapour, dust, icing

b). Diagram of connection with transmitter with “Hart” communication
If user wants to communicate with a smart transmitter (through HART protocol) by
making local connection of communicator or converter then user shall make sure that
resistance Ro seen from the terminals (2) and (3) of the display towards supply
source includes in the range 240[Ω]≤Ro≤1100[Ω]. For Ro<240[Ω] communication will
not be established. In such case, Ro shall be increased to the minimum value equal
to 240 [Ω].

9.3. Electrical connection in hazardous areas
In order obtain correct cooperation of the display with the rest of the system and
assure intrinsic safety conditions it is important to correctly connect the display with
particular emphasis on the requirements for the installation of intrinsically safe
systems (EN 60079-25, EN 60079-14) and meeting the input/output parameters.
Displays can be supplied from power supply and measurement equipment with
relevant intrinsic safety certificates, parameters of which for outputs to potentially
explosive areas should not exceed the limits for feeding parameters of displays
(permissible parameters of feeding the transmitters in hazardous areas see point
7.2).
Fig.7. Connection diagram of display WW-11ALW in potentially explosive zones
a). Diagram of connection with transmitter
b). Diagram of connection with transmitter with “Hart” communication
Communicator shall have approval for use in the hazardous zone and connecting it
to the signal line routed to the hazardous zone.
Transmitter shall be configured and calibrated in the safe area when such approval is
missing.
If we want to communicate with the smart transmitter (via the HART protocol) locally
connecting a communicator or converter we must make sure that resistance Ro seen
from terminals (2) and (3) of the display to the power source is in the range of
240[Ω]≤Ro≤1100[Ω]. When Ro<240[Ω] communication will not take place, then
increase the Ro to the minimum value of 240 [Ω].
