Checking the protective circuit

CenterMax Operating Instructions 61211-1020202
• Move the probe (head) in the x axis at constant speed.
• Try to stop the travel motion (v
x
) by pressing one hand against
the quill housing at the marked position (F).
This increases the shearing force of the drives. Once the shearing
force has exceeded a certain value, all drives will be deactivated.
v
x
: Speed of quill in x axis
F: Force exerted against the quill housing by pressing it with one hand.
Important!
You may press only against the quill housing.
• Do not press against the quill or against the probe head.
The probe head and quill could otherwise be damaged.
Check by a ZEISS service
engineer
Under normal circumstances, the force of your hand should suffice to
stop probe movement. If the movement can not be stopped in this
way, the protective circuit must be checked immediately by a ZEISS
service engineer.
• Call your service engineer and arrange for him to check the protec-
tive circuit.
Danger!
If the protective circuit is not functioning properly, the CMM must be
taken out of operation until the protective circuit has been checked by
a ZEISS service engineer.
Reactivating the drives
If you can stop the travel motions, you must reactivate the drives
