“SCD” DEVICE
The “SCD” Device can be setted to guarantee the safety of coupling and machine and the product quality.
The “SCD” device is an electronic controller which receives a train of pulses by a sensor. The pulses are converted into a voltage proportional to
the pulses frequency. This voltage is compared with a variable reference voltage (SET POINT). The internal relay changes over when the input
speed is faster or lower than the fixed (SET POINT). It is emploied to control the shaft revolution speed. In case of speed decrease, the device
gives a signal to the operator.

OPERATION
As the trasmitted torque is increased, this gives rise to an increased slip of the fluid coupling. Possible overload can be detected by measuring
the resulting speed reduction in the driven half coupling by means of overload “SCD”. This with change-over contact at the output may either emit
an alarm signal or switch off the main motor. A delaying action (max 120 sec.) prevent the unnecessary triggering of the relay, when the motor is
started. It only occurs once when the operating voltage is applied. False alarms are prevented arising from very short torque fluctuations, by the
introduction of a preset time lag (max. 30 sec.)

For the mounting of the ROTOFLUID coupling to the motor it is indispensable to operate on the shaft (1) of the coupling to avoid axial stress on
the bearings. It is recommended to fix on the motor shaft a screw stay (2) on which a nut (3) is tightened possibly resting to a thrust bearing (4)
(see Fig.1).
It is indispensable to lubricate the motor shaft before mounting the coupling.
Check that the coupling shaft rest on the motor shaft shoulder and lock by means of screw (5), spacer (6) (see Fig.2)

1) 1) Demount the ROTOFLEXI rubber element (F) as shown at Fig.1
2) 2) Fit the ROTOFLUID hydraulic coupling (A) on the motor shaft(M), fit the ROTOFLEXI hub (B) on the driven shaft ©. Assure that the driven

shaft is coaxial with the hydraulic coupling (A). The concentricity is assured when it is possible to fix the hub (B) to the hydraulic coupling flange
(A) by means of the screw (D), as shown at Fig.2. It is now possible to fix definitely the motor and the driven machine checking that between
the hub (B) and the driven shaft shoulder there must be a space (E) equal to the thickness of the rubber element (F).
3) Remove the screws (D), move the hub (B), place the rubber element (F), lock the screws (G) and (H) as shown at Fig.3.
