M9220-Bxx-3 On/Off Electric Spring Return Actuators Installation Guide
8
Once the command to rotate is removed, the actuator
holds its position, until either another command to
rotate is applied or until all power is removed. When
power is removed, the actuator spring returns to its -5°
position (unless an external mechanical limit is
reached). A stall condition while driving between -5 to
90° causes the output hub to stop motion and hold its
position until power is removed. Rotation is
mechanically limited to the -5 and 90° positions by
integral end-stops. Optional end-stops are available to
limit the output hub travel. An anti-rotation bracket
prevents rotational movement of the actuator body.
See Figure 9 and Figure 10 for proper wiring of the
M9220-Bxx-3 On/Off Electric Spring Return Actuator.
!
CAUTION: Risk of Electric Shock.
Disconnect the power supply before making
electrical connections to avoid electric
shock.
MISE EN GARDE : Risque de décharge
électrique.
Débrancher l'alimentation avant de réaliser
tout raccordement électrique afin d'éviter
tout risque de décharge électrique.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires may
result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit ou
connectés de façon incorrecte risquent
d'endommager irrémédiablement
l'équipement
IMPORTANT:
Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the M9220-Bxx-3 On/Off Electric Spring Return
Actuator.
