When the machine is equipped with a chain drive, a chain slipping control system is provided, featuring an
inductive sensor that counts the teeth of the hose guide chain pinion and relates them to the pulses
detected by the speed detection system. The first data to be set is the number of pulses detected for each
reel revolution that corresponds to the number of pinion teeth (figure 14), when the system is not present
leave 0 as the setting value, while if the system is present the exact number of pulses must be entered.

As shown in the new image, when the pulse value is different from zero, two new settable data appear
which represent the alarm thresholds. In the specific case the value indicated with the YELLOW danger
symbol represents the tolerance (in percentage) of the error that the machine can have on 4 reel
revolutions. When this threshold is exceeded, an alert is emitted but normal operation continues; the
machine is immediately blocked only if the error exceeds 150% of the threshold. The RED danger symbol
on the other hand indicates the slipping alarm threshold that immediately stops the machine if the threshold
is exceeded during the last half-revolution of the reel.
