3.13 Range Expander of X-3000-ce-UW
Range expansion divides the torque capabilities of a braking system into multiple
ranges. Only ranges required for a desired torque are active at any given time. This
feature allows a braking system to run a much wider scope of materials and tension
settings. Each combination uses the braking system to its maximum potential and
efficiency.
With a normal braking system, each brake pad is connected in parallel to regulated air
output. The pads may be divided into groups called ranges using the range expander,
which requires a P-3000 RE Pneumatic Interface. There can be anywhere between 2
and 4 ranges. Each range is driven from a separate valve switch in the P-3000. Using
this method, only the ranges required for adequate torque within the linear range of
brake functionality are active. The range expander will automatically switch in the
number of ranges that are required and raise or reduce pressure on the brake
accordingly. This will maintain the same tension across ranges.
Possible applications include:
The range expander can operate by two possible modes, by output or by diameter:
Changing Ranges by Tracking Output Pressure
Output Mode.
The range expander will change
to a lower range
when output
pressure regulates below 20%
[Dn Level]
for more than 20 seconds (range time) or
to a higher range
when output pressure regulates over 80%
[Up Level]
