Rotonivo

Function

2
A brushless synchronous motor drives a rotating measuring
vane.
When the material level reaches the measuring vane, it is
handicapped in its rotation. The motor is freely suspended
within the housing. The caused reaction torque is used to
3
operate a micro switch giving a signal output and to stop the
motor (figure 2).
When the paddle becomes free again due to falling material
level, a spring draws the motor back into his operating position,
the micro switch returns to his initial position and the motor is
switched on. The output signal is switched back (figure 1).

Signal output delay:
The version "universal voltage" and "PNP" has an integrated
adjustable delay for the signal output.

Option fail safe alarm
With the fail safe alarm it is possible to recognize a fault of the
unit in time and to initiate an alarm relay. The following faults are
observed:
• Motor
• Gear
• Electronic for motor power supply
• Supply voltage failure
• Defect of the connecting wires
Umschaltbare Sicherheitschaltung FSH/FSL:
