1. Overview
VISY-Output 8 is an 8-channel relay output module, installed in a case with the protection
IP66. It connects the VISY-X high-precision tank gauging system to external safety devices
or alarm indicators.
With VISY-Output 8, different alarm conditions detected by the VISY-X system will be
transferred to external devices. As VISY-Input 8 has its own housing it can be installed at
any position where the simplest wiring can be made. To connect to the VISY-X tank
gauging system only a low-cost communication cable has to be laid. Up to eight modules
VISY-Output 8 can be operated simultaneously with the VISY-Command.
2. Installation
2.1. Safety information
When installing VISY-Output 8 following safety instructions should be observed:
•VISY-Output 8 is designed for operation within the VISY-X system only.
•Modifications to the VISY-Output 8 are prohibited without the prior consent of
the manufacturer.
•All installation and maintenance work, with the exception of function testing,
must be carried out with the power disconnected.
•The installation and configuration of the VISY-Output 8 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 regula-
tions which are not stated in this technical documentation.
The safety instructions in this manual are marked as follows:
Failure to observe these safety instructions runs the risk of potential acci-
dents and damage to the VISY-X system.
Useful tips and information in this manual that should be observed are writ-
ten in italics and identified by this symbol.

Installation Page 2/11
2.2. Requirements
To connect the VISY-Output 8 to the VISY-X system an interface card of version VI 4 or
higher must be installed and connected to the communication adapter VISY-ICI 485.
2.3. Installation
The VISY-Output 8 is designed for wall mounting inside a building.
For mounting the casing cover must be removed.
2.4. Design and construction
The following figure shows the position of the connectors, LEDs and controls on the
board of the VISY-Output 8.

(5) 2-pin plug connector to activate a terminating impedance for the RS-485 inter-
face. Normally, the communication on the RS-485 network should be trouble-
free without activation of the terminating impedance (jumper not plugged in),
because the data rate is comparatively low.

2.5. Connection of the power supply
The power supply (230 VAC) has to be a permanent installation. The wires for the power
supply are to be connected to the screw terminals marked with PE, N and L.

2.6. Connection of the relay contacts
The VISY-Output 8 has eight output relays, each with a potential-free changeover con-
tact.
External safety devices or alarm indicators can be connected to the clamps marked with
relay 1 to 8 of the 24-pin screw terminal (see following figure). The VISY-Command alarm
signals can freely be assigned to the relays. Whether the contact shall be used as normally
open (NO) or normally closed (NC) depends on the particular application and the relay
mode (see chapter 3.3).
Figure 3: Relay screw terminal
2.7. Connection to VISY-Command
Up to eight VISY-Output 8 can be operated simultaneously with the VISY-X tank gauging
system. For the connection of VISY-Input 8 a communication adapter VISY-ICI 485 is
required which must be installed inside VISY-Command. The communication between
VISY-ICI 485 and VISY-Output 8 is performed via a galvanically isolated RS485 interface.
The communication line is to be connected to the terminals A, B and GND of the 3-pin
screw terminal.
For the wiring of VISY-Output 8 with VISY-ICI 485 it is recommended using a 3-core cable
with signal ground (GND connection terminal) to increase the noise immunity.

Additional information about the connection of the communication line can be found in
the documentation of VISY-ICI 485, see:

3. Configuration
Further configuration of VISY-Output 8 is done - as usual for the VISY-X system - with the
VISY-Setup configuration software.
If a VISY-Output 8 will be connected to the VISY-X system, the data proto-
col for communication with the VISY-Stick must always be set to “Multi
Probe”
using the VISY-Setup. Due to the shorter communication times, “Multi
Probe 4800 bps” should preferably be used.
Please follow the appropriate instructions in the VISY-Setup instructions.
•Technical Documentation VISY-Setup V4, art. no. 207158
Changing the configuration means to adopt VISY-Output 8 to the requirements of the
special application. The following settings are possible:
(1) Hold time after communication loss
(2) Output action after hold time
(3) Relay mode
(4) Relay delay
After the configuration it should be tested whether the alarm signalling
works as expected.
3.1. Hold time after communication loss
With the hold time it is configured if and when the outputs react after a communication
loss. The hold time can be configured in the range of 0 to 240 minutes.
Hold time = 0 (minutes)
The hold time is deactivated. The outputs keep their current states.
Hold time = 1 - 240 (minutes)
The hold time is set to 1 - 240 minutes. After the hold time is exceeded, the outputs react
as described in the following chapter.

Configuration Page 6/11
3.2. Output action after hold time
This configuration defines how the outputs react after the hold time is exceeded. After
the hold time the outputs can either be activated or deactivated.
If a hold time of "0" is configured, the outputs keep their current states.
The relays act according to the configured relay mode.
3.3. Relay mode
The following relay modes are possible:
Standard mode
In the standard mode, the relay is normally de-energized (passive) and it will be energized
(active) when the corresponding output is activated.
Fail-safe mode
In the fail-safe mode, the relay is normally energized (active) and will be de-energized
(passive), when the corresponding output is activated.
The fail-safe mode provides the advantage that even in case of a failure
in the power supply of the VISY-Output 8 an alarm can be signalled via
de-energized (passive) relays.
The following table shows the state of a relay depending on the configured relay mode
and the state of the associated output.

Page 7/11 Fault diagnosis
3.4. Relay delay
If the relay delay is on, the relay state (de-energized/energized) changes when the event
for the output activation is present for at least 1 minute. The relay delay occurs only upon
activation of an output. Upon deactivation of an output the relay state changes without
delay.
If an output is activated and the relay delay is on, the corresponding output
LED blinks slowly to show the delayed reaction of the relay.
3.5. Maintenance Mode
The maintenance mode is used to deactivate the outputs of the VISY-Output 8 temporari-
ly. This function can for example be used during the configuration to prevent alarms via
the relay contacts caused by incomplete configuration. The maintenance mode is turned
on or off using the VISY-Setup configuration software, as far this function is supported by
the used version. During the maintenance mode, the output LEDs flash rapidly.
The maintenance mode is terminated automatically when VISY-Setup is
closed or the connection between VISY-Setup and the VI interface card is
interrupted.
Before activating the maintenance mode you should be sure about possible
consequences, as active safety devices might be turned off.
4. Fault diagnosis
VISY-Output 8 has several LEDs which help in diagnosing problems. The positions of the
LEDs can be found in the Figure 1.
4.1. Transmit LED (7) / Receive LED (8)
The two red communication LEDs indicate, whether data are received or transmitted from
VISY-Output 8.
Under normal conditions, the communication LEDs should light up
regularly.
