Page 1/9 Overview
1Overview
The VISY-Output 1 is a 1-channel relay output module for connecting an external safety
device or an alarm indicator to the VISY-Command. Alarms detected by the VISY-X tank
gauging system can thus be forwarded to an external system. With the VISY-ICI 485, the
VISY-Output 1 can be extended with the VISY-Output 8 and the VISY-Input 8 modules.
VISY-Output 1 is located on a module carrier for installation on DIN mounting rails and is
intended for installation in the VISY-Command, from which the wiring is done.
Only one (1) VISY-Output 1 is allowed to be connected to the VI-4 interface in
the VISY-Command.
2Installation
2.1 Safety instructions
When installing VISY-Output 1 following safety instructions should be observed:
•VISY-Output 1 is intended for use within the VISY-X system only.
•Modifications to the VISY-Output 1 are prohibited without the prior consent of
the manufacturer.
•All installation and maintenance work, except for the functional inspection must
be performed when the device is not under current.
•The installation and configuration of the VISY-Output 1 may be carried out only
by expert personnel. Specialised knowledge must be obtained by regular training.
•Operators, installers and service technicians must observe all applicable safety
regulations. This also applies to any local safety and accident prevention regulation
which is not stated in this technical documentation.
The safety instructions in this manual are marked as follows:
If these safety instructions are not observed, it may result in the risk of accidents
or damage to the VISY-X system.
Useful instructions to be followed in this manual are displayed in italics and
are marked with the adjacent symbol.

Installation Page 2/9
2.2 Requirements
For installing the VISY-Output 1 in the VISY-Command, an interface card of version VI-4 or
higher must be present.
2.3 Installation
VISY-Output 1 is designed for installation in the VISY-Command. For installation, the VISY-
Output 1 is plugged onto the DIN mounting rail inside the VISY-Command. Hold the
module carrier of VISY-Output 1’at an angle to the mounting rail and plug the snap-on
foot onto the rail in such a way that one side of the module holder is fixed in place. Then
press the other side of the module carrier onto the rail until this side snaps in and the
module carrier sits firmly.
The VISY-Output 1 can be used only in conjunction with the VI-... interface
card (version VI-4 and above).
Mount the VISY-Output 1 leftward next to the VI-... interface card on the DIN rail.
The module carrier can be released from the rail only by levering with a
screwdriver
2.3.1 Design and construction

2.3.5 Connection of the relay contacts
The VISY-Output 1 has a relay with a potential-free changeover contact. An external safety
device or alarm indicator can be connected to the terminals marked NO – C – NC of the 3-pin
screw terminal (see figure below). Whether the contact is to be used as a closer (NO –
Normally Open) or as an opener (NC – Normally Closed) depends on the specific application
and the relay’s operating mode (see chapter 2.4.3).
Figure 2: Relay screw terminal
2.3.6 Connection to the VISY-Command
Connect the VISY-Output 1 to the VI-… interface card using the 6-pin ribbon cable sup-
plied (see Figure 1: Structure of VISY-Output 1). The power supply and communication
are established through this ribbon cable.
NO CNC

Installation Page 4/9
2.4 Configuration
As is typical for the VISY-X system, the VISY-Output 1 is configured using the VISY-Setup
configuration software.
With VISY-Setup the data protocol for communication with VISY-Stick must be
set to “Multi Probe protocol” . Due to the shorter communication times, it is
preferable to use “Multi Probe 4800 bps”.
For addressing, the serial number of VISY-Output 1 must be entered in VISY-
Setup.
Please follow the appropriate instructions mentioned in the VISY-Setup manual.
•Technical documentation VISY-Setup, Art. No. 207158
Changing the configuration adjusts the VISY-Output 1 to the requirements of the relevant
application. The following settings are possible:
(1) Hold time after communication loss
(2) Behaviour of the output after the hold time expires
(3) Relay mode
(4) Relay delay
After configuration, it should be checked whether the alarm signalling works as
expected.
2.4.1 Hold time after communication loss
The hold time (timeout) is used to determine whether and when the output should react
after a communication loss. The hold time can be configured from 0 to 240 minutes.
Hold time = 0 (minutes)
The hold time is deactivated. The output maintains its current status.
Hold time = 1 – 240 (minutes)
The hold time is set to 1 – 240 minutes. After the hold time has expired, the output behaves
as described in the following chapter.

Page 5/9 Installation
2.4.2 Behaviour of the output after the hold time has expired
This setting is used to specify how the output behaves after the hold time expires
(timeout). After the hold time, the output can either be activated or deactivated.
If a hold time of "0" is configured, the output does not change its state.
The relay behaves according to the set relay mode.
2.4.3 Relay mode
The following relay operating modes are possible:
Standard mode
In the standard mode, a relay is normally de-energised (passive) and becomes energised
(active) when the output is activated.
Fail safe mode
In the fail safe mode, a relay is normally energised (active) and becomes de-energised
(passive) when the output is activated.
The fail safe mode offers the advantage that even if the auxiliary energy of
VISY-Output 1 fails, an alarm signal can be sent via the relay that is then
going passive.
The following table shows the status of the relay based on the configured relay mode and
the status of the output.
Relay mode

Table 1: Relay mode
2.4.4 Relay delay
If the relay delay is activated, the relay status (passive/active) changes as soon as the event
for activating the output is in cue for at least 1 minute. Relay delay occurs only during
output activation. If the output is deactivated, the relay status changes without delay.
If the output is activated, the relay delay is turned on.

Installation Page 6/9
2.4.5 Maintenance mode
The maintenance mode is used to deactivate the output of VISY-Output 1 temporarily. For
example, this function can be used during configuration to prevent an alarm from trigger-
ing through the relay contact due to a still incomplete configuration. The maintenance
mode is turned on and off using the VISY-Setup configuration software, if this function is
supported.
The maintenance mode automatically stops as soon as VISY-Setup quits or
there is no longer a data connection between VISY-Setup and the VI-... interface
card.
Because the maintenance mode may deactivate active safety devices, one
should be aware of the possible consequences before the activation.

Page 7/9 Fault diagnosis
3Fault diagnosis
VISY-Output 1 has several LEDs to make diagnosis easier when there are problems. The
position of the LEDs can be seen in Figure 1.
3.1 Relay LED (3)
The red LED for the relay shows whether the relay is energised or deenergised (active or
passive).
3.2 Status LED (4)
The yellow status LED gives information on the status of communication between the VI-...
interface card in the VISY-Command and the VISY-Output 1.
The following table lists the possible states of the status LED and explains their meaning.
Status LED
Fault
Meaning
On
No error
Correct data is being received regularly
Continuous flash
No communication
No correct data received since the last switch-
on
1 short flash

interruption
No correct data received for longer than 1
minute
2 short flashes
Hold time exceeded
No correct data received for longer than the
configured hold time
Table 2: Status LED
Under normal conditions, the status LED should be on constantly.
3.3 Operating voltage LED (5)
The green operating voltage LED shows whether the VISY-Output 1 is being supplied with
power. After the auxiliary energy is turned on, the operating voltage LED glows continu-
ously. An LED that flickers or goes out indicates a problem with the auxiliary energy or the
electrical adaptor.
