Unlocking
-
manual unlocking
turn the enclosed handle anticlockwise (VRE; VU120) or clockwise (MARKAGE MB; VUW120). -
remote unlocking
power cables 1 and 2.
Resetting
-
manual resetting
turn the enclosed handle clockwise (VRE; VU120) or anticlockwise (MARKAGE MB; VUW120). -
motorised resetting
power cables 1 and 3.
MANF - Upgradeable remote controlled unlocking mechanism
The unlocking mechanism MANF EVO unlatches the damper blade via remote control by sending an electric impulse (VD) or by interrruption (VM) of the magnets power supply. A begin- and end of range switch (FDCU) is standard available.
The blade can be reset manually (MANF EVO) or by an electric motor ME (option and kit).

Unlocking
-
manual unlocking
use the unlocking button (1). -
automatic unlocking
n/a -
remote unlocking
(option VD/VM MAN EVO FDCU) by sending an electrical impulse (VD) or by interrupting the power supply (VM) to the magnet's entrance.
Resetting
-
manual resetting
turn 90° counter-clockwise with a hex socket wrench 13 mm (2). -
motorised resetting
(option ME MANF) switch off the power supply for at least 10 sec. Power the actuator for at least 30 sec. (respect the prescribed voltage and polarity). The resetting stops automatically if a torque > 20 Nm is detected.
NF - Remotely controlled spring return actuator (for small dimensions)
The servomotor is designed to control smoke control dampers from a distance. This solution is suitable in case of counter-pressure.
Beginning and end of range switches included.
- Access for manual resetting
- Locking button
Variants

NF24
Actuator NF 24V -
NF230
Actuator NF 230V
Unlocking
-
manual unlocking
use the enclosed handle and turn 1/4 turn counter-clockwise; push the locking button to the left. -
automatic unlocking
n/a -
remote unlocking
by interrupting the power supply (for dampers with NF/SF-VD module: by sending an electrical impulse).
Resetting
-
manual resetting
use the enclosed handle and turn counterclockwise. To block the motor, push the locking button to the right. -
motorised resetting
switch off the power supply for at least 10 sec (3 sec for NF/SF-VD module). Supply the actuator (respect the prescribed voltage) for at least 180 sec. The resetting stops automatically when the end of range is reached (damper closed).
SF - Remotely controlled spring return actuator (for large dimensions)
The servomotor is designed to control smoke control dampers from a distance. This solution is suitable for use in case of counter-pressure.
Beginning and end of range switches included.
