1.1 About this document
This Service Manual is part of the device documentation of the
FLOWSIC600-XT with the further components:
●Operating Instructions (Part No. 8018846)
●Interface Description FLOWSIC600-XT
This version is valid for:
●FLOWSIC600-XT with firmware as from firmware version V1.x.xx
●Operating and Parameter program FLOWgate as from version 1.x.x
All service work that can be carried out by trained personnel is described. The valid Operat-
ing Instructions contain all basic information on the measurement method, layout and
function of the measuring system and its components as well as on using the device, there-
fore additional information is only provided here where necessary to understand the func-
tion.
The Service Manual may therefore only be used together with the valid Operating Instruc-
tions.

1.2 For your safety
1.2.1 Intended use of the device
The measuring system FLOWSIC600-XT is used for measuring the actual volumetric flow
rate of gases transported in pipelines. Apart from that, the FLOWSIC600-XT can also deter-
mine the actual corrected volume and the sound velocity.
The measuring system shall only be used as specified by the manufacturer and as set forth
below. Special attention must be paid that:
●Usage is compliant with the technical data, specifications on allowable use as well as
the requirements for assembly and connection, and ambient and operating conditions
(to be found in the order documents, on the type plate and in approval documents, and
the Operating Instructions).
●All measures required for value conservation, e.g. for maintenance and inspection,
and/or transport and storage, are observed.
●The device is not subjected to any unallowed mechanical stress, e.g. through pig clean-
ing.
1.2.2 Authorized personnel
Persons responsible for safety must ensure the following:
●Any work on the measuring system may only be carried out by qualified persons and be
approved by responsible skilled persons.
●Qualified persons are those who, based on their training, experience or instruction as
well as their knowledge of relevant standards, regulations, accident prevention rules
and plant conditions, and authorized by those responsible for persons and plants to
carry out such work. It is decisive that these persons can recognize and avoid any possi-
ble hazards in good time. Skilled persons are persons in accordance with
DIN VDE 0105 or IEC 364, or directly comparable standards.
●These persons must have and demonstrate exact knowledge on hazards arising from
operation, e.g. through hot, toxic, explosive gases or gases under pressure, gas-liquid
mixtures or other media as well as adequate knowledge of the measuring system
gained through training.
●It is important that, during all work on the measuring system, the persons have received
training by “SICK Engineering GmbH”.
●In hazardous areas with potentially explosive atmospheres, wiring and installation shall
only be carried out by staff trained according to EN60079-14 and according to national
regulations.

1.2.3 General safety instructions and protective measures
Improper use or handling can cause health or material damage. Please therefore read this
Section thoroughly and observe this information during all tasks on the FLOWSIC600-XT as
well as the warning and caution information in the individual Sections of this Service Man-
ual.
Basically applicable:
●Always comply with the statutory provisions and the associated technical rules and reg-
ulations relevant to the equipment when preparing for and carrying out any work on the
measuring system. Pay particular attention to potentially hazardous aspects of the
equipment, such as pressurized piping and explosion protection zones. Always pay spe-
cial attention to the relevant regulations.
●All work must be carried out in accordance with the local, system-specific conditions
and with due consideration to operating hazards and specifications.
●The Operating Instructions belonging to the measuring system as well as system docu-
mentation must be available on site. Always observe the information on the prevention
of injuries and damage given therein.
●Depending on the particular hazard potential, an adequate number of suitable protec-
tion devices and personal safety equipment must be available and used by the person-
nel.
1.2.4 Hazards by hot, corrosive and explosive gases, or high pressure
The FLOWSIC600-XT is fitted directly in the gas-carrying line. The operating company is
responsible for safe operation and for complying with additional national and company-
specific regulations.
WARNING: Hazards by the gas in the system
The following conditions can increase the risk:
●Toxic gas or gas dangerous to health
●Chemically aggressive gas
●Explosive gas
●High gas pressure
●High gas temperature
▸ In installations with an increased risk, the FLOWSIC600-XT may only be
fitted and removed when the line is vented or when the installation is at a
standstill.
▸ The same applies to repair and service work which involves opening any
pressurized component or the explosion-proof SPU.
Otherwise health or injury risks can possibly arise through escaping gas (e.g.
poisoning, burns).
WARNING: Hazards through leaks
Operation in leaky condition is not allowed and potentially dangerous.
▸ Regularly check leak tightness of equipment.

1.2.5 Hazard through heavy loads
The FLOWSIC600-XT measuring system must be attached securely to the carrying structure
when being transported and installed.
▸ Only use lifting gear and equipment (e.g. lifting straps) suitable for the weight to be
lifted. Maximum load information can be found on the type plate of the lifting gear.
NOTICE:
The lifting lugs are designed for transporting the measuring device only.
Do not lift or transport the FLOWSIC600-XT with additional loads using these
lugs.
