1Introduction
Note Available features depend on
urchased device version. All here
described features are not available in
all device versions.
LCD240 is a graphic LCD display with a horizontal
resolution of 128 by 240 and vertical resolution of
240 by 128 pixels. The display is optimized for lift
applications. It can be assembled either to a car or to
a level. It can present floor markings, direction ar-
rows and other graphical symbols needed for special
indications. Also other information, such as time and
date, a company logo or “floor info pictures”, can be
presented on specific versions. The user editable floor
info pictures enable presentation of any useful infor-
mation associated with certain floor(s) in addition to
a regular car position indication.
2 Display items, symbols and fields
Display is divided to four sub-areas. Names of these
fields are as follows:
Arrow/symbol field (80 x 96)
Floor marking field (48 x 96)
Logo field (12 floor info pictures only available for
LCD 240 HXC) (160 x 32)
Date and time field (only available for version HX)
Intorduction
Display items, symbols and fields
LCD 240-2xx
In normal situation an arrow is displayed in the
“arrow/symbol field” and a floor marking is displayed
in the “floor marking field”.
Appearance of the arrows can be either automatic or
externally controlled. Selection is made in the setup
menu.
When the external mode (“EXT”) is selected, appea-
rance and direction of arrow is controlled by 2 inputs
ARR-UP and ARR-DOWN (J2 / 13…14). Input
B5/MOVE (J2 / 6) activates arrow scrolling.

5
When the automatic arrow function is selected
(“AUTO”), the microcontroller continuously observes
the car position status input. In case of any change it
evaluates the direction of car movement and presents
an arrow pointing to that direction. When the floor
code stop changing, the arrow is blanked after
3 seconds.
LCD240 is capable to present 4 different symbols.
Their appearance is controlled by 4 symbol indication
inputs (J2 / 7…10). In addition, the symbol number
4 can be configured to appear when the car is in a
certain floor.
Symbols have priority: symbol number 3 overrides
symbol number 4, symbol number 2 overrides symbols
number 3 and 4, etc. Normally (and as factory default)
symbol number 1 is used for fire alarm, 2 for over-
weight and 3 for service. Own symbols can be edited
and downloaded by means of LCD240-2xx
Configurator software.
When any of the 4 symbols is displayed, it appears in
the “arrow/symbol field”. Arrow and floor marking are
both displayed in the “floor marking field”
Optional “floor info pictures” appear always in the
logo field and also optional date and time appear in
the “date and time field”.
3Electrical connections
Supply voltage (12V…24V DC) is applied to J1 connec-
tor. The device is controlled through a 14-pin connec-
tor (J2).
The connector has:
5 inputs (J2 / 1…5) for the position status,
4 inputs (J2 / 7…10) for the symbol indications,
2 inputs (J2 / 13…14) for the direction arrows and
1 input (J2 / 6) that activates the arrow scrolling
Refer to “Electrical specifications” for voltage levels
and other details.

4Electrical adjustment
LCD display contrast can be adjusted by trimming
potentiometer R57. Default contrast setting is
made in factory.
5Configuration
Device can be configured in two different ways: By
means of devices own setup menu or with “LCD240-
2xx Configurator” PC-software. We recommend using
LCD240-2xx Configurator software; it is easier and
more illustrative.
“Programming” must be enabled (ie. PROG ON), when
programming the device with LCDtool. After program-
ming, the mode has to be disabled (OFF).
When programming mode is “off”, the pin connector
is active.
“Emergency info picture” parameter is used for se-
lecting the picture to be shown in the center of the
display when power failure occurs. There are three
pictures available
Electrical adjustment
Configuration
LCD 240-2xx
Two jumpers should be set to match the input signal
polarity. J8 is for the position status inputs and J4 for
the others. When changing the jumper positions, first
disconnect the device from the power supply, then
change the jumper positions and after that connect
the device back to power supply. This is because the
device automatically adapts to different input polari-
ties by reading the jumper positions to memory when
power is switched on.

6Setup Menu
With the aid of the setup menu the user can make
changes to certain properties of the device. Three
push buttons are assigned to browsing of the menu.
Pressing the SET push button for at least 3 seconds
activates the setup menu.
If there are more than two possible values, FW steps
to the next value and BW to the previous one. Value
is stored by pressing the SET button. Text “STORED” is
displayed and device returns to menu browsing
mode. If browsing is paused (no key is pressed) for 10
seconds, device returns from setup menu to standard
display mode.
Setup Menu:
• Inputcoding(BIN/GRAY)
• Logographics(OFF/ON)
• Programming(PROGOFF/ON)
• PowerFailurePolarity(PFPOLAR0/1)
• Arrowinputselection(EXT/AUTO)
• Emergencyinfopicture(EMERINFO0…2)
• Floormarks(BUS00…BUS31)
• Time/Date
Menu items are scrolled by buttons FW (forward) and
BW (backward) and selected by SET button. When
selected, pressing the FW button toggles between
values.
While editing floor marks there is one more step nee-
ded. Floor mark consists of up to two characters, so
the first pressing of SET button makes first character
editable by buttons FW and BW. Second pressing di-
rects editing to second character and finally the value
is stored by third pressing of the SET button like
usually.

VEBUS A1 – Parallel to serial converter
11.5 Function
Device reads its parallel input every 100 ms. If there
is a change in the parallel input, device immediately
sends the serial control packet to V EBUS interface.
Device also sends the serial control packet every 500
ms, if there are no changes in the parallel input.
10.6 Electrical adjustment
Jumper J5 should be set tomatch the input signal
polarity. When changing jumper position, first dis-
connect the device frompower supply, then change
the jumper position and after that connect the de-
vice back to power supply. This is because the device
automatically adapts to different input polarities by
reading the jumper position tomemory when power
is switched on.
