1Characteristic features of the VISY-View
The VISY-View display is an optional component of the VISY-X system (volume
information system).
The VISY-X system can be used to carry out precise, continuous filling level measurements
of up to 16 tanks directly at the filling station. At the same time, the product temperature
and the water level at the tank bottom are also measured. As an extension, several
environmental measurement sensors can be connected.
The system includes:
control unit VISY-Command
up to 16 measurement sensors VISY-Stick
up to 16 measurement sensors VISY-Stick/-Reed Interstitial
up to 16 measurement sensors VISY-Stick/-Reed Sump Manhole
up to 16 measurement sensors VISY-Stick/-Reed Sump Dispenser
up to 8 VISY-Input 8 to connect external systems
up to 8 VISY-Output 4
configuration software VISY-Setup
VISY-View can be used to evaluate and show the tank data alternatively to the filling
station computer.
The display VISY-View serves the purpose of indicating recent tank data, delivery data and
various alarm messages provided by the control unit VISY-Command (see separate
instruction manual "VISY-Stick and VISY-Command").
The appliance is equipped with a four line display screen. VISY-View makes use of an LED
and a buzzer to signal alarm statuses, a serial interface to enable printing alarm and tank
data via a printer, two potential-free outputs to control external devices when selectable
alarm statuses are activated, and one remote input for the connection of a switch.

3Structure and mode of operation
The VISY-View display stands on two nonslip feet in order to ensure unproblematic
operation of the buttons.
The front operator side is screwed at an angle with the feet so that user-friendly
operation is ensured. The operator interface comprises the display screen (1) and five
operator buttons (4–8). For the indication of operating statuses, the VISY-View unit is
equipped with two LEDs (2–3) (see Figure 1)

Page 6/34 VISY-View

3 Alarm LED 7 Cursor right / down
4 Alarm 8 Cursor left / up
3.1 Display screen
The display screen (1) represents four lines each with 20 characters. The different data
supplied from the control unit VISY-Command are generated in several submenus (see
chapter "Menu structure") and are shown on the display screen (1). Except for the main
and configuration menus the first line of the screen always shows the relevant tank
respectively probe. The other three lines are used to display the relevant tank data or
alarm messages. By using the two cursors you can recall the various menu functions to
the display.
There are two different cursor forms:
The Up-Down cursor „█“ which moves up and down on the left side in the
display screen and marks specific lines.
The Left-Right cursor "</>" which pages through the menu items at the
beginning of a line.
The cursor is moved using the operator buttons (7 and 8). Regular blinking of the Up-
Down cursor or changing between "<" and ">" indications show the properly running
program.
VISY-View is provided with a protective function that switches off the
display screen automatically following a configurable period of time (1–
60 minutes) without any inquiry via the operator buttons. This function
prevents the free view of data. The display screen is switched on again by
pressing any button.

3.2 Operation elements
3.2.1 On-Off switch
The on-off switch (9) is found on the underside of the device (see Figure 2). After
installing and turning on the device by using the on-off switch, the "Power" LED lights up
green (see section "Power LED" in this chapter).
Figure 2: VISY-View rear
3.2.2 Operator buttons
To page through the various menu items and call up the desired tank data, five operator
buttons (4–8) are available (see Figure 1):
Cursor left / up (8) depending on the cursor form with two functions:
1. By this button the Up-Down cursor is moved upwards. You can select a sub-
menu of the main menu or individual menu items of the submenu. If the cursor is
already positioned in front of the top line, you can go to the superimposed menu
by pressing this button.
2. The Left-Right cursor pages via this button through the various menu items of
the submenus.
Cursor right / down (7) depending on the cursor form with two functions:
1. By this button the Up-Down cursor is moved downwards. You can select a
submenu of the main menu or individual menu items of the submenu.
2. The Left-Right cursor pages via this button through the various menu items of
the submenus.

Page 8/34 VISY-View
Return button (6) has four functions:
1. With the Return button you can change between the two cursor forms.
2. In the main menu only the Up-Down cursor exists. Here you will use the Return
button to confirm the selection of a submenu.
3. In the alarm menu, only the Left-Right cursor exists. Here the Return button is
used to acknowledge an alarm message (the "!" will no longer be shown, the
red Alarm LED changes from flashing to constantly on and the buzzer is switched
off).
4. In case of acknowledged alarm messages, you can also use the Return button
to toggle between the indication "alarm status" and "alarm time".
Print (5)
This button can be used to initiate a data output operation via the printer. It is
possible to print out all data available in the submenus “Tank data”, “History”,
“Configuration” and maybe other submenus that might exist. More information
about the different printouts can be found in the chapters of the individual sub-
menus.
This operator button will only initiate printing operations if the
connected printer has been configured (see section "Printer" within
chapter "Configuration").
With the printer activated, the printing-out of alarm messages and filling
operations is carried out automatically in case of an alarm activation or a
filling operation.
A thermal printer with 32 columns and serial interface has to be used.
This printer is available as an optional equipment unit from FAFNIR.
Alarm (4)
By pressing this button, the alarm menu is called up. In the case of a new alarm,
the alarm initiating tank or probe appears on the display screen, (the red Alarm
LED flashes and the buzzer sounds). Pressing the button repeatedly will display all
the alarm messages that have not been acknowledged yet in successive order.
When all the alarm messages have been acknowledged with the Return button
(5) (see above), the red Alarm LED changes from flashing to permanently on and
the buzzer is switched off. To exit the alarm menu, press the alarm button once
again.

VISY-View Page 9/34
3.2.3 Key switch
Through connection 13 (see Figure 3) an accessible key switch can be mounted for use by
tanker drivers in case the filling station has already closed. Before refilling, a repetitive
turning of the key switch will bring the relevant data of all the tanks one after another
onto the display screen. Which three Tank data for a tank should be displayed are
selected in sub menu "Configuration" under "DspTruck" menu point (see section "Truck
display" in chapter "Configuration").
3.3 Power LED
The green Power LED (2) lights up as soon as the unit is connected to the power supply
system and is switched on by means of the on-off switch (9) (see Figure 2).
3.4 Interfaces
The VISY-View display is equipped with the following interfaces:
Figure 3: VISY-View interfaces
(10) Connection to appropriate power supply unit included in the scope of supplies
(11) Alarm outputs (11a = output 1, 11b = output 2)
The two alarm outputs can be configured so that a potential-free
transistor is closed for a specific alarm status (see chapter "Configura-
tion" and load limits in chapter "Technical data").

Page 10/34 VISY-View
When connecting the alarm outputs the correct polarities must be
observed ("+" for connections 1 or 3). If the poles are confused
then the contact is always closed!
(12) RS-485 interface for connection to the control unit VISY-Command
(13) Remote input for a key switch (see section "Key Switch" in this chapter) or input
for an external alarm (see section "Alarm input" within chapter "Configuration")
(14) Sub-D socket (9-pin) for connection to a printer
A thermal printer with 32 columns and serial interface has to be used.
This printer is available as an optional equipment unit from FAFNIR.
3.5 Alarm signalizing
The VISY-View display is equipped with a red Alarm LED (3) and a buzzer in order to
indicate alarms optically and acoustically. All detected alarms of the VISY-X system are
displayed. Alarms are either coming directly form connected probes or are the result of
exceeding or dropping below alarm thresholds of the control unit VISY-Command, set via
the software VISY-Setup.
The buzzer is switched off as soon as all alarms have been acknowledged in the alarm
menu, using the Return button (see section "Operator buttons" in this chapter). When
acknowledging an alarm the operator confirms that he/she has noticed the alarm. The
alarm menu can only be left after all alarms have been acknowledged. The volume of the
buzzer can be adjusted in the submenu "Configuration" (see section "Loudness buzzer"
in chapter "Configuration").
The alarm signalisation can be in one of the following states depending on the current
alarm situation:
Alarm signalisation Alarm situation
Alarm LED is flashing
Buzzer is on
There is at least one unacknowledged alarm, in this case it is
insignificant if the alarm is still active or not.
Alarm LED is on
Buzzer is off
There is at least one active alarm and all alarms have already
been acknowledged.
Alarm LED is off
Buzzer is off
There is no alarm.
When turning the device on the red Alarm LED lights up for approx. 1
second.
A new alarm is indicated by a flashing Alarm LED while an acknowledged
alarm is indicated by an Alarm LED that is constantly on.

4Putting into operation
In order to put the VISY-View display into service, proceed as follows:
(1) First choose which RS-485 interface of the control unit VISY-Command will be
used to connect the display VISY-View.
The display VISY-View is connected to the host interface of the VISY-Command
when no other host system (e. g. POS system) will be connected.
If the host interface of the VISY-Command is already used by another device
VISY-View must be connected to the extension interface of VISY-Command.
Figure 4: Interface connections of VISY-Command
(2) Use the configuration software VISY-Setup to configure the interfaces of VISY-
Command (see separate operating instructions for VISY-Setup). If the host inter-
face is used to connect VISY-View, enter "108" as host computer. If the exten-
sion interface is used, activate the function "External display" when using VISY-
Setup version up to V2.10, or activate the function "Extension interface" with
version V3.00 and higher.
The required protocol configurations for the VISY-View are described in
section "Protocol", chapter "Configuration".
(3) Connect the RS-485 interface of the VISY-View display to the RS-485 interface of
the control unit VISY-Command using the terminal clamps 5 (B) and 6 (A) of the
VISY-View (see rating plates in Figure 5 and Figure 6).
With devices from no. 525, terminal 7 can be used, if required, to apply
a cable screening or for potential equalisation with the RS-485 interfaces
of connected devices. Terminal 7 may not be connected to earth poten-
tial, as there is the danger of potential equalisation currents which are
too high and could damage the interface.
