“Selematic” function
When working reels with high diameter and weight ranges, in order to maintain the same material tension,
the torque required from the brake when the reel has the maximum diameter is much higher than the
torque requested from the brake when the reel has the minimum diameter. Therefore, the brake must size
itself dynamically to adjust itself to the instantaneous torque requested, rendering the adjustment more
sensitive even when low torque levels are required from the brake.
The “Selematic” function manages, through two electro valves, the activation of three different braking
sections (section 1 is always active) whose torque percentages are known. In this way it sizes the brake
according to the instantaneous torque requirements.
The figure shows the pneumatic connection diagram of the three braking sections to the 2 electro valves and
to the transducer.
How to assign the calipers to the braking sections
SECT.1 Calipers that develop the smallest torque of the brake must be connected in section 1 (in the
example a caliper at 16%).
SECT.2 Calipers that develop a higher torque than the calipers in SECT.1 must be connected in section 2 (in
the example a caliper at 40%).
SECT.2 max (maximum value that can be assigned to section 2) = SECT.1 x 4 (in the example 64%)
SECT.3 Calipers that develop the highest torque must be connected in section 3 (in the example a caliper
at 100% plus a caliper at 40%).
SECT.3 max (maximum value that can be assigned to section 3) = (SECT.1+SECT.2) x 4 (in the
example 224%)
Note: All the examples refer to the maximum configuration, that is three braking sections.
However, only two braking sections can be set (SECT.1 and SECT.2) as long as the assignment criteria set out
above are complied with, and you set SECT.3 = 0, as it is absent and unusable.
RE calipers torque percentages
The torque percentage developed by each
caliper is shown by the colour found on the
actual caliper:
Black = 100 %
Red = 40 %
Blue = 16 %
Yellow = 10 %
