Selection Of Installation Site And Installation Conditions; Required Room Height; Ambient Conditions; Vibrations At The Installation Site - Zeiss CONTURA G2 Installation Instructions Manual

1. Selection of Installation Site and
Installation Conditions
When selecting the installation site, please make sure
that the following conditions either already exist or can
be implemented there.
The system comprises the following components:
1. Coordinate measuring machine
2. Controller
3. Control console
4. Data station (peripherals)

1.1 Required Room Height

This dimension equals the sum of the height of the coor-
dinate measuring machine and a minimum overhead
clearance of 200 mm.
Example: Contura G2
Height of CMM
Minimum installation clearance
Required minimum room height above
floor or foundation
1.2 Required Floor Surface
A cutout layout plan is included in this brochure to give
you a quick overview of the required floor surface. When
preparing the space assignment plan, make sure that
your CMM is well accessible from all sides.
Please select the installation site so that there is a distance
of at least 800 mm between the CMM and the wall.
1.3 Transport Lanes
Please check the ground-floor and upper-storey floor
loading capacity of all transport lanes leading to the in-
stallation site. The doorways must be at least 5 cm wider
and higher than the largest packaged unit, including the
transport vehicle. The dimensions and weights of the
transport units are specified in this brochure.

1.4 Ambient Conditions

Bridge-type coordinate measuring machines are high-
tech products. Their specified quality is attainable only if
you ensure that the following conditions are met.
Permissible Storage Temperature Range
5°C to 40°C
Pay special attention to the storage temperature during
winter. Avoid storing at temperatures below 5°C.
Ambient Conditions for Operational Readiness
Permissible ambient temperature: +17°C to +35°C
Permissible air humidity:
40% - 60% without condensation
Sound level at installation site: <90dB
Max. altitude above sea level: for 100 - 125 V 3000 m
Temperature Conditions for Operation of CMM:
The measuring uncertainty specified for your CMM can
be guaranteed if:
1. you use a measurement correction program and enter
the workpiece and CMM temperatures as well as the
temperature expansion coefficients of the workpiece
material.
2. the following temperature conditions are observed:
CMM Type
2800 mm
CONTURA G2
200 mm
CONTURA G2 HTG
(optional)
3000 mm
Please make sure that sufficient lighting is available.
1.5 General Protective Measures
The CMM must be protected against dirt and foreign par-
ticles (e.g. casting sand, metal filings and bore chips, oil,
coolants, lubricants and soot). Deposits of materials such
as casting sand and swarf may lead to increased expenses
for cleaning and maintenance.

1.6 Vibrations at the Installation Site

The following diagram(s) show(s) the permissible floor vi-
brations.
Vibrations are often caused by heavy processing machin-
ery, transport vehicles (cranes or stackers) and stamping
or forging machines located in adjacent rooms.
A measurement is required to determine the actual mag-
nitude of local floor vibrations. You can order such a vi-
bration analysis from Carl Zeiss Oberkochen. Please call
or e-mail your contact person for more details.
In any case, the results must be made available to CZO for
evaluation.
1.7 Floor Load
When calculating or planning any floor reinforcement
(foundation etc.) which may be required, it is advisable to
