1. Operation of X-ray devices

1.1 German X-ray Ordinance (RöV), Information on radiation protection

The following information refers to the operation of X-ray devices in the Federal Republic of Germany. In other

countries, the locally applicable regulations must be observed by the operator.

The METROTOM system fulfills the conditions of Annex 2, Item 3 of the RöV (X-ray Law); it thus complies with

the properties of a fully protected device.

Operation of the METROTOM must be approved in compliance with § 3 of the RöV.

In order to obtain an operating permit, the operator must do the following:

• Have the METROTOM inspected by an authorized independent expert for technical inspections of X-ray systems.

• Authorize a (local) radiation protection officer.

• Submit an application for a permit to operate the system to the supervisory authority far enough in advance of the

beginning of operation. The components of the permit application include the result of the inspection performed by

the above expert, the personal data of the radiation protection officer, proof of his technical qualification and autho-

rization, etc.) as well as detailed information on the radiation protection organization.

The supervisory authority can stipulate further conditions which must be fulfilled as a prerequisite for the notice of ap-

proval.

According to § 18 of the RöV, the METROTOM must be inspected by an authorized expert after 5 years of operation at

the latest (recurring inspections).

The responsible supervisory authority of the relevant state is usually the Trade Supervisory Authority, the Occupational

Health and Safety Administration or the Regional Board.

United states

The system conforms to 21 CFR 1020.40

Typically, an x-ray system must be registered with the appropriate state agency. This registration must occur prior to the

x-ray system being placed into service. Regulations may require initial and periodic inspections by a government agency

or a qualified vendor. In addition, the regulations may require the implementation of standardized operating procedures,

specialized training and posting of radiation exposure warnings and other special notices. Radiation safety requirements

differ significantly from one jurisdiction to another. It is the users' responsibility to ensure that the x-ray system is installed

and operated in compliance with all applicable governmental regulations. Failure to comply may result in substantial pen-

alties.

Other countries

In other countries, the national regulations regarding x-ray protection must be observed.

It is advisable to report a planned installation to the supervisory authority in due time, i.e. 2 to 3 weeks in ad-

vance.

3. Preparations for installation / Electric power supply

Please make sure that the following preparations are made by the date of installation:

3.1 Preparation of required floor space

The floor space must be clean.

Maximum difference in level of the 4 seating surfaces: ≤

4 mm

Maximum slope per contact surface: 1 mm/m

3.2 Electric power supply

We recommend connecting the system to an electric power line which is not used to supply any peak load equipment

(elevators, air conditioners, etc.). To prevent negative influences, avoid installing the CT scanner near:

– systems with a high power consumption: (e.g. welding machines) and

– systems that emit strong perturbing radiation: (e.g. electrical discharge machines).

The use of mobile telephones or walkie talkies within a radius of ≤

3m around the machine also must be prohibited. If

properly enforced, these measures will help prevent malfunctions, especially in connection with the electronic data

processing systems.

A 5-pin CEE-form plug connection or an equivalent national plug or permanent connection is provided for the system (16

A). This connection must be protected with an automatic cutout. Alternatively, you can also use other protective devices

with an equivalent rating. It is recommended to install a lightning current arrester, e.g. Phoenix Flashtrab FLT 25-400, as

a coarse protection against overvoltages.

We recommend making the connection according to the following connection diagram, however, also would like to point

out that the pertaining national laws and regulations must be observed.

This is a class A device, and may therefore cause radio interference in the surrounding area. In such cases, the operator

may be required to take appropriate action and bear any costs thus incurred.

3.5 Installing the Connecting Cables

The cables can be protected by installing them in an electric raceway included in delivery. This raceway can accommodate

all cables and must be fastened to the floor. Or, as an alternative, the cables may also be installed in an underfloor cable

duct.

3.6 Stabilization of the power supply

If brief fluctuations occur in the root mean square value of the line voltage, a line voltage analysis must be performed.

cable from the main distributing frame to the connecting point of METROTOM is sufficient in most cases.

3.11 Compressed air supply

Please make sure that the compressed air supply required to operate the METROTOM is provided as follows:

● Minimum pressure 6 bar, maximum pressure 10 bar.

● Precleaned air; free of dirt particles, water residues and oil vapors.

● Air quality according to ISO 8573 Part 1 Classification 4 including:

Sect. 6.1: Max. particle size 15 µm, max. dirt particle concentration 8 mg/m

Sect. 6.2: Max. dew point of compressed air = +3° C

Sect. 6.3: Max. oil concentration of 5 mg/m

If the above air quality is not attained, an additional air filtration unit and, if necessary, a membrane dryer must be con-

nected upstream. These units can be ordered from CZ; ask your contact man.

If the required air quality is not attained, this could cause damage not covered by the warranty.

Air consumption (rotary table):

Max. 15 l/min at 5bar (75 normal liters/min at 1 bar).

Connection point for compressed air

Our service engineer requires a connection point to connect the METROTOM to the compressed air supply. You should

provide this connection point as shown in the brochure. The machine-side connection (9x2.5) is provided for compressed

air hoses with an internal diameter of 9 mm. The air supply line from your connection to the connection point of the

METROTOM will be laid during installation.

If you do lay the air hose up to the machine, please make sure that the connection point is accessible. The air hose must

be laid in such a way that it is protected.

3.12 Unloading/Transport vehicles

The unloading and transport of packaged units may be performed only with hoisting rings or pallets; the insulated pa-

kkaging must not be damaged in the process. Please ensure that suitable transport vehicles operated by qualified

personnel are provided for unloading the crates and transporting them to their storage site. The type of transport vehicle

used depends on local conditions. The load carrying capacity of the transport vehicles is specified on the following pages.

Suitable transport vehicles include e.g.:

● forklifts ● mobile cranes ● gantry cranes

Keep all transport paths free during installation to ensure a smooth workflow. Always remember that the CMM is a valu-

able, precision instrument and that jolting the crates or setting them down hard therefore must be avoided.

Transport locks, lashing straps, shipping crates and pallets must be returned.

Since packaging materials such as e.g. plastic foils or styrofoam chips are recycled by Zeiss, they can be returned

along with the transport locks if they are clean and no dirt or debris is mixed in with them.

3.13 Storage/Unpacking

If the outside temperature is <0°C, the machine assemblies are shrink-wrapped in aluminum-coated foil instead of a pro-

tective PVC wrapping, with a desiccating agent added (insulated packaging).

Please store the packed unit in a covered location as close as possible to the installation site.

Preliminary temperature adjustment:

Transport the assemblies no less than two days before our system specialist is due to arrive to a storage site with an am-

bient temperature of ≥ 15° C. The assemblies may be unpacked and the insulated packaging removed only by our sys-

tem specialist! Please provide an appropriate location for the empties.
