Tankvision Gauge Link Basic safety instructions
Endress+Hauser 5
2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill the
following requirements:
• Trained, qualified specialists: must have a relevant qualification for this specific function
and task
• Are authorized by the plant owner/operator
• Are familiar with federal/national regulations
• Before beginning work, the specialist staff must have read and understood the instructions
in the Operating Instructions and supplementary documentation as well as in the
certificates
(depending on the application)
• Following instructions and basic conditions
The operating personnel must fulfill the following requirements:
• Being instructed and authorized according to the requirements of the task by the facility's
owner operator
• Following the instructions in these Operating Instructions
2.2 IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
2.3 Designated use
2.3.1 Application
The Tankvision Gauge Link is a tank gauging protocol converter to allow integration of third
party gauging equipment into the Tankvision system. The Tankvision Gauge Link is available
with a range of different field bus interface options. Most field bus interfaces will support
connection of a number of gauges in a “multi-drop” or bus configuration. The number of
gauges which may be configured in the Tankvision Gauge Link is limited to 32, which should
be adequate for most typical tank gauging field busses, however electrical and / or protocol
limitations may reduce this number. The functionality which obtains will be determined by
that offered by the connected gauge(s) and the interface / protocol.
Connection to the host system is via EIA/TIA-485 (formerly RS-485) Modbus. This is
primarily intended for “one-to-one” connection with the Tankvision Tank Scanner or similar
device.
The Tankvision Gauge Link must only be used in “safe” areas where there is no hazard from
the presence of potentially explosive or flammable atmospheres.
The Tankvision Gauge Link has not been assessed in respect of functional safety.
Accordingly it is not intended to be used as a safety critical component or part of a safety
critical system or in the implementation of any safety function.
2.4 Workplace safety
For work on and with the device:

Basic safety instructions Tankvision Gauge Link
6Endress+Hauser
• Wear the required personal protective equipment according to federal/national
regulations.
• Switch off the supply voltage before connecting the device.
2.5 Operational safety
Risk of injury!
• Operate the device in proper technical condition and fail-safe condition only.
• The operator is responsible for interference-free operation of the device.
• In normal operation the Tankvision Gauge Link contains hazardous voltages. Connectors
on the front panel, accessible behind the front cover / door are “touchproof”, but care
must be exercised when carrying out service work with the door open. The unit must not
be operated with any other cover removed.
• If (or it is suspected that) any liquid or conductive object or debris has entered the
enclosure of the Tankvision Gauge Link, the mains supply to the equipment must
immediately be isolated.
Proper operation of the Tankvision Gauge Link is dependent upon correct installation and
configuration. The equipment must be operated and maintained by suitably trained and
competent personnel who are aware of and fully understand the instructions provided
herein.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers
• If, despite this, modifications are required, consult with Endress+Hauser.
Repair
To ensure continued operational safety and reliability,
• Carry out repairs on the device only if they are expressly permitted.
• Observe federal/national regulations pertaining to repair of an electrical device.
• Use original spare parts and accessories from Endress+Hauser only.
The Tankvision Gauge Link contains no user-serviceable parts. Other than the mains supply
fuse, the Tankvision Gauge Link contains no user replaceable parts. Any modification or
repair work must only be performed by the manufacturer or its authorised agents.
2.6 Product safety
The device is designed to meet state-of-the-art safety requirements, has been tested and left
the factory in a condition in which it is safe to operate. The device complies with the
applicable standards and regulations as listed in the EC declaration of conformity and thus
complies with the statutory requirements of the EG directives. Endress+Hauser confirms the
successful testing of the device by affixing to it the CE mark.

Installation Tankvision Gauge Link
10 Endress+Hauser
5Installation
5.1 Mechanical installation/mounting
Prior to installation, visually inspect the Tankvision Gauge Link for any signs of damage.
Confirm that the type label shows the correct field bus interface for the intended application.
The Tankvision Gauge Link must only be installed in a “safe” area where there is no hazard
from the presence of potentially explosive or flammable atmospheres.
The Tankvision Gauge Link must be installed in a cabinet or similar enclosure which provides
protection against dust and water ingress. The location must also provide protection against
moisture or the formation of condensation.
Ensure that the temperatures likely to be encountered at the installation location lie within
the relevant minimum /maximum operating and storage temperature ratings of the
Tankvision Gauge Link.
The Tankvision Gauge Link should not be installed near to high voltage circuits or to cables
feeding motors or other high current loads, or near to contactors, variable frequency drives,
inverters or frequency converters or other switchgear / controlgear which may emit
significant electromagnetic interference.
A clear space of about 50 mm (1.97 in) above and below the Tankvision Gauge Link
enclosure should be allowed for ventilation. A gap of 10 mm (0.39 in) to either side of the
Tankvision Gauge Link will ease mounting and opening of the front cover of the enclosure.
GaugeLink_Dimensions
The enclosure of the Tankvision Gauge Link is intended to be mounted onto “top hat” DIN
rail, T35 to BS EN 60715 (or BS 5584 / EN 50022 / DIN 46277-3). The rail should be
mounted on a vertical surface, with the rail running horizontally, so that the Tankvision
Gauge Link connection plate / access cover is to the front and in a readily accessible location.
To attach the Tankvision Gauge Link to the mounting rail, first hook the enclosure over the
top of the rail, then turn downwards until the spring clip on the back of the enclosure latches
onto the lower edge of the mounting rail (fig. A below).
