What you should know!

Safety devices must be checked regularly. Some safety devices must be
checked at least once every three months, for others a check once a
year is necessary. A distinction is made between a check by the operator
and a check by a specialist.
NOTE
When the function of the safety device cannot be guaranteed, the
CMM must not be operated. Inform a ZEISS service engineer.

Check by the operator

Checking the collision protection
The CMM is equipped with safety devices for the ram and the probe.
Both safety devices must be checked at regular intervals.
Collision protection function
When the travel movement is hindered by a collision with the ram or the
probe and triggers the collision protection function, the drives must au-
tomatically switch off.
NOTE
The function of the protective device must be checked regularly in order
to guarantee safe operation of the CMM. Check the protection device
function at every start-up.
In automatic measuring mode with maximum travel speed, the CMM's
working area must be delimited using additional measures. For more in-
formation, please refer to the »Installation site requirements«.
Checking the ram collision protection
It is recommended that the collision protection function is checked daily.
A check should be carried out when the machine is at rest.
