Operating Procedure For The - Gates 507C Manuel D'utilisation

3. Operating procedure
for the 507C meter
The sonic tension meter enables non-contact,
simple and accurate measurement of installation
tension by analysing sonic wave action, which is
related to belt function. The sonic wave is
generated by flipping the belt span with the belt
standing still, and it is captured by the sensor
UK
and processed by a high performance computer.
Belt tension is displayed in digital mode.
Attaching sensor
Each of the male and female connectors has a
notch on the surface. Fit the connectors together
at the notch and push them together. To
disconnect, hold the collar on the sensor and pull
out.
Turn on the power
Press the "Power" key and the LCD screen
displays the current input data storage register
number. To change, refer to "Input data storage
and retrieval".
Enter belt unit weight
M =
(Grams per metre length per millimetre width –
enter factors page 10-11-12).
Capacity available for input is from 000.1 to
999.9 g/m/mm. Push the "Weight" key and enter
numbers on the keypad. Make sure the decimal
is placed correctly in the display panel. If your
entry is incorrect push "Weight" again, and the
cursor returns to the original position.
Enter width or number of
ribs/strands
W =
Capacity available for input is from 000.1 to
999.9 mm or number of ribs or strands. For a
synchronous belt, enter the width in millimetres.
For a Micro-V
a Polyflex
Enter the number of ribs/strands only for the belt
being tested.
Enter the span length
S =
Capacity available for input is from 0001 to
9999 mm. The span length represents the
distance between the contact points on adjacent
sprockets/pulleys/sheaves. This distance may
be measured directly, or it may be calculated from
the formula below. Calculating the span length
gives the best results.
