Information on disposal of used equipment.
BASIC REQUIREMENTS AND SAFE USE
The manufacturer will not be liable for damage resulting from incorrect installation,
failure to maintain a suitable technical condition of the device or use of the device
other than for its intended purpose.
Installation should be carried out by qualified staff having the required authoriza-
tion to install electrical and I&C equipment. The installer is responsible for perform-
ing the installation in accordance with manual as well as with the electromagnetic
compatibility and safety regulations and standards applicable to the type of instal-
lation.
In systems with I&C equipment, in case of leakage, there is a danger to staff due
to the medium under pressure. All safety and protection requirements must be
observed during installation, operation and inspections.
If a malfunction occurs, the device should be disconnected and handed over to the
manufacturer or an authorized representative for repair.
In order to minimize the risk of malfunction and associated risks to staff, the device
is not to be installed or used in particularly unfavourable conditions, where the fol-
lowing hazards occur:
−possible mechanical impacts, excessive shocks and vibration;
−excessive temperature fluctuation;
−water vapour condensation, dusting, icing
Changes made to the manufacturing of products may be introduced before the paper version of the
manual is updated. The up-to-date manuals are available on the manufacturer’s website:

8.3. Electrical connection of display in safe areas
Figure 5. Connection diagram of WW-11ALW display in the safe zones.
a) Diagram of connection with transmitter;
b) diagram of connection with transmitter with Hart communication.
In order to communicate with the intelligent transmitter (via HART protocol), before connect-
ing the local communicator or converter, it is necessary to check whether the Ro resistance
seen from terminals (2) and (3) of the display towards the power source is in the range
240≤Ro≤1100 Ω.
8.4. Electrical connection of display in hazardous areas
In order obtain correct cooperation of the display with the rest of the system and assure in-
trinsic safety conditions it is important to correctly connect the display with particular empha-
sis 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 in-
trinsic 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 6.2).

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 miss-
ing.
In order to communicate with the intelligent transmitter (via HART protocol), before connect-
ing the local communicator or converter, it is necessary to check whether the Ro resistance
seen from terminals (2) and (3) of the display towards the power source is in the range
240≤Ro≤1100 Ω.
8.5. Earthing

9. OPERATION
The LCD has three primary information fields in the figure belowa as LCD1, LCD2, LCD3.
Figure 8. Display information fields.
LCD1 - value of current or guidance percent preset range display. Depending on the display
configuration will be displayed the current value of the current line 4…20 mA with a resolution of
0.1 mA, or percent guidance the preset range with a resolution of indications 1%.
LCD2 –display field for the digital value measured by display, the value rescaled by user’s units, and
error codes. The position of the decimal point can be set in the local MENU.
LCD3 –information field. During normal operation it is designed for continuous display of the base unit
or the user units. In the MENU operation mode it displays the setting options. It is also used to display
errors related to the execution of commands in the local setup MENU.
Display backlighting - local display is equipped in backlight which can be switched on or off depend-
ing on needs. Switching the backlight on increases the voltage drop for all versions by 3 V. Enable or
disable the backlight is possible using the jumper after removing the back cover of the display. The
method of switching the backlight on or off is shown in figures below.

9.1. Display configuration
The user can change the display settings using the buttons below the display. The buttons can be
accessed by unscrewing the display cover. The buttons are marked with symbols: [↓], [↑] and [●].
The buttons [↓], [↑] are used to move up and down the MENU structure, and the button [●] confirms
and executes the selected option. Pressing and holding any button for about 4 seconds will cause
enter to the local setting mode, and the following message “EXIT” appears on the display in the field
LCD3. No activity in the MENU area for longer than 2 minutes automatically exits the local setting
mode and goes to display process variable. After confirming the selected parameter, the display will
confirm the acceptance of the command with a "DONE" message. The "← BACK" button allows to
move up a level higher in the MENU structure.
The way of navigating in the MENU structure of the local display is shown in the diagram below.
