Cleveland Motion Controls Classic CLT Cantilevered Transducer REV AA - Manual

1.0 GENERAL INFORMATION
1.1 RECEIVING AND UNPACKING
Handle and unpack the equipment carefully.
Immediately upon arrival, check the shipment against the
packing list. Any damage should be reported
immediately to the carrier and to the nearest CMC®
representative.
Equipment which will not be installed immediately should
be stored in a clean, dry location. Precautions should be
taken to prevent moisture, dust and dirt from
accumulating in storage and installation area.
1.2 PRECAUTIONS
1.2.1 Shipping - It is recommended that the sensing roll
be removed when the machine is shipped with the
transducers mounted. The shock and vibration
transmitted to the transducers by the sensing roll during
transporting can damage them.
1.2.2 Handling - An impact such as dropping the
transducer or a sharp blow to the transducer can
damage it. The unit should be completely surrounded by
a soft foam cushion when being transported.
1.2.3 Overloading - Repetitive overloading above the
maximum working force, shock or severe overloading
should be avoided because they can damage the unit.
1.2.4 Overvoltage - The excitation voltage should not
exceed 10 VDC or AC (RMS). Excessive voltage can
destroy the semiconductor strain gages.
The voltage between the gage and beam or base
(ground) should not exceed a peak of 50 volts.
Exceeding this voltage can cause an insulation
breakdown between the gage and the beam.
